About Slack

Slack is a cloud-based project collaboration and team interaction tool designed to facilitate communication across organizations. The solution caters to various industries, including media, research, technology, education, financial services, retail, transport, and logistics. Slack provides public channels for members across organizations to start conversations. Private channels enable interaction within smaller teams, and direct channels help send messages directly to colleagues. Slack incorporates feeds from social media into the application and blends them with ongoing conversations in various channels. Files such as PDFs, images, documents, and spreadsheets can be shared via drag and drop. Slack archives messages, notifications, files (as well as the contents of files) and projects, all of which can be searched for later. Slack allows users to customize their notifications and reduce their scope. All changes are reflected in the native applications available for iOS and Android.

I sometimes wonder how collaboration worked before Slack

I find it hard to remember life before Slack. We all worked in a single open plan office but, like most offices, still communicated predominantly from our desks. Our go to IM tool was Skype and it was an easy way for conversations to get siloed. Slack brought those conversations out into the open, made them discoverable and brought in automations to make them richer. If you're debating whether to use Skype or Slack there really is no contest. I'd also suggest it outperforms Teams and other competing collaboration and instant messaging tools for it's deep integrations.

Pros

Real-time instant messaging, file sharing and integrations with key apps that automate important proceses mean a high percentage of tasks can be managed all in one place.

Cons

Threads are often difficult to keep track of. Slack has done its best to elevate Threads but I still find myself missing things when people don't @ mention me.

Alternatives Considered

Microsoft Teams

Reasons for Choosing Slack

Skype made conversations difficult to discover and groups were transient forcing you to recreate those groups over and over again. It also had no integrations and automations of value to us.

Reasons for Switching to Slack

Better integrations, better interface, more automations, better suited to a creative/tech environment

My favorite corporate messenger

I’ve been using Slack for about 5 years. Before that, I tried two other popular corporate messengers. In my opinion, Slack is the best corporate messenger on the market.

One of the best features is its integration capabilities. For example, we integrated Slack with our web application, so now we receive instant notifications in Slack whenever a critical issue arises, allowing us to react immediately.

I also use Slack for saving project-related notes. It’s convenient to keep everything organized and easily accessible in one place.

Pros

Slack is incredibly user-friendly and makes it easy to manage multiple workspaces, enabling simultaneous communication both within my company and with customers. I especially like the threads feature—it helps keep discussions organized and makes it easy to find information when needed. I also like the customizations and automation you can set up, which saves time.

Cons

I use Slack on both my phone and laptop, but sometimes I have an issue where I can’t answer a call on my laptop because it’s active on my phone instead.
Also, sometimes when a colleague calls me using Apple headsets, I can’t hear them.

My time with Slack

My overall experience with slack was beneficial when communicating with other team members during the process. When you take the time to figure out the organization process, and receive instruction on how to use the software than things seemed to run smoothly.

Pros

When using slack to communicate with former employers and coworkers in training I noticed it's efficient communication tools. One example of this is that you can operate the program by creating different channels. Operating in different channels is key to organization when you want to transition from different communication sources between individuals. Another important feature that slack offers is file sharing. File sharing allows you to share with others, and you also have the choice to file share with another privately. The program seemed to operate smoothly without any glitches. Slack is a great way to communicate and is suggested for Employer's new hires.

Cons

The only disadvantage I have had by using Slack were minor annoyances when finding some of my former conversations. I also feel that many icons made my scrolling around the program disorganized.

Great tool that allows us to practice what we preach when working with our clients

My company is small and started using it this year. The rollout has been smooth in some cases and bumpy in others. The biggest problem I run into is other users not knowing how to use it. However, as we train each other and our clients, it gets a bit easier everyday and is incredibly.

Pros

There are many things i like about it!
-How many apps it integrates with
-That I can manage projects both internally and externally and communicate freely
-All of the templates are helpful and good quality - many of them are perfect right out of the gate
-That you can communicate via threads so the main message board remains clean and not bogged down with a ton of back and forth
-That you can choose which parts of threads you want to post to the comment board if needed.
-The ability to create workflows

Cons

There are a couple of things I don't like:
-With workflows, you can't create conditional steps. For example, if I want to create a form where the questions change based on the answer to the prior question, you aren't able to do so. You essentially have to make additional workflows/forms for each.
-It gets a bit messy, even if you're great at setting up notifications, channels, communicating through it etc., it can get out of control quickly. Plus, you also have to rely on other people's knowledge on how to use the tool. If someone you're communicating with doesn't know Slack well, you can't be sure if they'll understand how to check for message, have proper notifications etc.

Overall positive

Overall, my experience with Slack has been very positive. It’s an essential tool for team collaboration, especially in remote or hybrid work environments. It helps keep communication efficient and organized through channels, direct messages, and integrations with other apps. While it can sometimes be overwhelming with notifications, setting clear boundaries and customizing alerts helps manage this. Slack has definitely improved how our team communicates and stays connected.

Pros

What I liked most about Slack is how it keeps communication organized and accessible. The channel system is great for separating topics or projects, and the integrations with tools like Google Drive and Trello make it easy to streamline workflows without switching apps. The clean and intuitive interface also makes it easy to navigate, even for new users.

Cons

One downside of Slack is the potential for notification overload, especially in larger teams where messages can pile up quickly. It can sometimes feel overwhelming to keep up with everything. Additionally, while the search function is helpful, it could be more intuitive when trying to locate older messages or specific files in busy channels.

Our remote team loves slack!

My remote team loves slack! So much easier to use than Gmail's chat feature! We love that it is easy to use on our phones, too!

Pros

I love that I can easily communicate with my remote team, schedule impromptu video calls, and integrate apps! I also branded our slack channel to our company's brand!

Cons

Slack will notify you with notes about your apps, tags, etc. It can get confusing if you get a lot of notifications (ex. a note that your google drive file might not be accessible to everyone in the channel). You have to close out the notification to remove it from your channel feed. It's only visible to you, but still annoying!

Easy communication for anyone anywhere

Slack is the best communication tool that I use, and I haven't thought about moving away from it.

Pros

Slack is a super easy platform to communicate on, whether with family, friends, coworkers, and professional communities. I use Slack every day for all of the above, and it keeps me connected whether at my desk or on the go.

Cons

Some of the best features are behind a paywall, like keeping messages after 90 days.

A solid option to centralize communications

I have been using Slack since around 2016 or 2017. It's been long enough that I don't remember exactly when.

Pros

Communication is seamless. Even though it is an instant messaging product, it lends itself surprisingly well to transactional communication as well, effectively replacing email for most use cases.

Cons

Search is painful. Notifications with channel membership takes some work to get right.

Pros

User experience, connecting with other companies via Slack Connect. Also Huddles are a great feature.

Cons

Automation is a bit tricky. Managing User Groups and default channels have been a pain point as well.

It is more than satisfactory as a communication tool.

As a communication tool, the overall quality is excellent, with no need to worry about bugs. It offers various features, and it’s up to you how to make use of them. By integrating with desired apps, we could automate certain tasks within Slack. For large organizations, Slack alone can serve as an assistant, making it an excellent tool for time management.

Pros

I liked that members who joined a channel could freely invite other members.

Cons

I found it challenging to understand the Connect feature because the rules seemed unclear when it involved admins.

Google Hangouts Replacement, Saved us from Teams

I actually enjoy Slack. It is fun to use, and I like much more than sending an email.

Pros

Slack really allows us to communicate effectively based on group or subject. We can communicate directly in the General chat, directly, or in any number of specialized group channels. Each team has their own channel, and if needed, that channel can be locked to prevent other teams from entering.

Most are open channels that allow for any of our teams to come in and converse on the subject titled. One our favorite things to use are external apps. I love that Slack will pop up an upcoming appointment or if we need a meeting in say Zoom, I can just type /zoom and it will generate a Zoom link and we can all join in. We are on the free tier, so with the higher level tier, you can get conferencing and a wealth of other features added in. The free level serves us very well.

We use email integration also, so important emails and even things like weather alerts pop up as a Slack notification. It is really a great service.

Cons

Can be confusing to use if you are not used to chat systems such as Hangouts or WhatsApp though. The idea of a separate room, or Group chat, confuses some, but once they see how things work, it is a non-issue.

Reasons for Switching to Slack

Microsoft Teams is a poor implementation of what Slack is. It is a burden to use. The layout of the Teams application was awful and the channel layouts were hard to use. It was free to use also, but we did not want to deal with that headache. I think that if Teams did not come with O365, people would not use it. It is awful. Slack is designed so much better overall.

Slack: a good business instant message application

My experience with Slack has been really good.
Slack helps me a lot on my daily activities and even more when I'm working from a remote location or inspecting something and need to interact with our team at the main office.

Pros

Slack is easy to use and its interface is very similar to other IM applications we have been using for years.
That makes the transition from whatever IM software currently in use to Slack quick and smooth.
In our company, nobody needed to be trained to use Slack and users went well with the transition process.
Slack allows users to customize their names, profile picture, and current status.
It's also possible to send messages to individuals, groups of people, and into channels.
Users most commonly send text messages but they have the option to send screen captures, pictures, and files in general at their own convenience.
A very useful resource in my opinion is the ability to create shared channels where you can add people from outside your organization as well as users from other Slack organizations.
With this feature, you can create a support channel with a service provider and have quick interaction with them, for example.

Cons

I don't have too much complaints about Slack.
One of them is that as an Administrator, I believe that the management interface is a bit confusing.
Sometimes it takes me a while to remember certain basic operations because Slack has its own way of having that done.
Also, I had issues with some of my users a couple of times because of bugs with Slack application.
The last I remember would freeze half of the user's screen so nothing shown in that area was clickable of selectable.
Closing and reopening Slack would temporarily solve the problem.
I contacted Slack support and they confirmed that as a known issue and that would be fixed soon with a software update.

Slack is a great collaboration tool for our team, improves communication and productivity.

I am very happy of using it as a main communication tool at work. And I have been using it for a few years now. Every colleague I worked with, they all like it. I hope slack keep up the good work and make more neat features for us all.

Pros

Slack is a team communication tool, it very well categories the different processes in different channels, restrict the conversation is relevant to the channel and everyone who join that channel can collaboratively contribute to the topics.

It also provides a neat feature call thread, which you can start a discussion under a message and solve issues with that person. It reduces the distractions from the channels and help other members concentrate on the topics they care about.

You can also integrate automatic messages from other apps, softwares, e.g. we implemented the gitlab automation messages in the developers channel, it indicates what work has been done, it passes or break the build, etc.

Lovely integration of slash command feature, for giphy images, for icons, for text formats, etc. Making the conversation more fun.

You can also pin useful information, that you can easily access in anytime.

Cons

when you enter a message without sending, it places that person's icon into a draft section in the navigation area. It is kind of tricky to find that person, if you forgot you have a pending message to send and you are wondering why that persion is disappeared from your direct message section.

search bar can be improved as well, it would be nice to have more advanced search terms like what google does.

Great communcation software

Like I had said I really love Slack. It has made it easier to communtate with my team, share information and it actually brought us together!

Pros

I have used Slack for years now and was so excited when we started using it at my current workplace. We had tried to use other software but it never really took off as Slack has. It is super easy to use and has many different client versions. Everyone in the office can decide how they want to use it which is a hugeeeee plus! We use the free version which really is great for us. There is a limit to how many message Slack stores but this hasn't been a huge issue. You are able to create different channels which has been a great way to share important information that we have to reference and keep it organized. Slack has also brought our team together and gave us a new modern way to communicate. Also what I love is that you can really customize notifications,

Cons

I don't like how with my particular phone notifations can be delayed. It has caused a few issues where I have gotten messages 30 to 40 minutes later despite having good either wifi or ceular service. Otherwise no real issues with Slack!

Slack solves most issues, but not all

Slack felt very familiar for me since I already used Discord for social and gaming needs. I liked the ability to customise my interface with literally any colour I chose and the apps and addons I could add (namely, ClickUp) were extremely helpful.

However, the pricing model proved a bit too aggressive for my company. I have a small design company in Brasil (which means North American dollars are about five times as expensive for me from the get go), and our biggest selling point is the fact that we keep very close contact with our clients, bringing them into most design discussions. In that light, my intention was to seamlessly transition all my clients from their WhatsApp groups to their own Slack channel. The issue was that *even paying*, the amount of "free guests" I could invite was very limited. I was not able to add all clients, and that ultimately meant I couldn't fully transition to Slack. A small issue I also had was inviting via e-mail instead of (again, like in Discord or even WhatsApp itself) just generating a link my clients would click and be dropped into the channel created a small learning curve.

Unfortunately, we ended up having to migrate to Discord itself in order to get out of WhatsApp.

Pros

It essentially makes e-mailing obsolete and has several neat utilities that help streamline the thought, decision, discussion and feedback processes.

Cons

I had less control than I expected (and needed) in regards to overall look and feel, as well as the users' level of interaction in an attempt to soften the learning curve and address some of the app-switching angst. On top of that, the imposing pricing limitations effectively made it impossible for my company to fully transition to Slack.

Alternatives Considered

Zoom Workplace, ClickUp and Google Meet

Reasons for Choosing Slack

WhatsApp groups were excessively hard to manage without having a dedicated phone number for work. Personal messages would get mixed up with work messages and it made everyone's life harder. Also, clients were very keen on sending voice messages, which not only aren't appreciated by everyone, but also don't work as express proof in case we needed to document our choices.

Switched From

WhatsApp

Reasons for Switching to Slack

The turning point at the time was the ability to interact with screenshared video calls through a virtual pen. It was great for lessons and quick suggestions. My familiarity with Discord made my own transition easier and audio/video quality was a plus. Overall, I liked Slack very much, but wasn't able to move over entirely.

One of the Best Collab tools!

Overall the tool is used to communicate and share files amongst your own team as well as other teams which are external to yours. Its great for announcements or even details that you can pin to each individual or team chat. The channels allow you even finer controls over who can see it, participate, as well as the overall purpose. Its a superb tool for having each team create their own channels as well as special channels which can be used for announcements, heads up, changes, basically anything you need to communicate across. It is everything you would expect in a collaboration tool.

Pros

Ease of use and the feature list is probably why this tool does so well. It even allows you to build custom apps that you can implement with your existing apps/tools for a more streamlines experience! Its honestly made life a lot easier to collaborate amongst team members, especially during Corona times and working from home.

Cons

There really isn't much about this tool that I don't like. It runs smoothly and constantly has new updates to make the experience even better. The only thing I can think of is that it can be resource intensive at times but honestly it has not slowed me down yet. Also, when sharing your screen with another team or individual, you have to go back to the initial chat to send a message, it would be nice if it can be done from the same UI of the screen-share. Well made tool overall!

There's Everything Else, Then There's SLACK

We were having to find a way of maintaining connectivity as the company went into a fully remote work environment. Prior to COVID 19 we were heavily dependent on in person communication to get tasks completed and communication organized. Post COVID we've actually increase our productivity in task completion and maintained or increased out teams communication and morale through the features of Slack. Without it out company would certainly have had a bigger negative impact from COVID, now we're not just surviving, we're thriving!

Pros

Mobile and desktop notifications, specific channels to tailor communication based on the audience, having a log history to lock back on, easily sharing files, integrations that make workflows easy, increasing productivity and connectivity with remote teams, creating a culture that cares

Nothing overly stands out as something that isn't to like. There's so many customizations and personalized controls that give the users the level of interaction that they want and need. Slack continues to set the bar.

Community Management for Non-Profit organizing

Setting up Slack was quite easy once we received a non-profit grant for the standard license. Some people had to be taught in detail but the transition was overall fluid and is now universally considered a smart move.

Pros

Slack enables structured communication within and across working groups (protest planning, tech, outreach, lobbying, etc.). Having access to all relevant streams of communication in one place (that isn't the personal messenging app) is crucial to maintain any semblance of structure.

Cons

It took some time to figure out proper ways to handle our most common workflows with or without bots and integrations (eg. voting, scheduling). Integration with our knowledge base app, Nuclino, remains barely functioning.

Alternatives Considered

Rocket.Chat, Mattermost and Microsoft Teams

Slack is very useful... Specially if you pay!

I think Slack is very good for team communication, though not "the only answer". I say this because, for example, it isn't the most appropriate tool to handle team wide calls.

It's worth to pay for it if you need to access your history files and conversations.

Pros

I really like the way Slack enables team communication. I have used Slack in both paid/free versions.

I used the free version (limited storage for conversations and files) in a 40 people co-located team. It was very good for short interactions and immediate file sharing. We had a link with Jira, so we were always seeing issues being updated and such. Previously, we had Trello and it work very good too.

I currently use the paid version in a remote team and it's our day to day communication means. We have linked GitHub to have a "center monitor" for created issues, pull requests, etc. Also, all of the alerts, regarding website functionality/life are connected in real-time to Slack, so we never miss an alert.

It's very useful to have the paid version as it holds the whole conversation and file history. It's very easy to use the search function to find my own files or even things that were discussed in conversations.

Cons

After a while (or update, I'm not sure) using the free version, the storage of conversations and/or files didn't lasted much. So, if you had a conversation last week, forget about going back to that.

Also, in the free version it feels very much as if your files and conversations are held as hostages.

I think there are still some integrations that needed to be improved, for example, when I accidentally accepted to show previews of GitHub issues I couldn't find a way to turn it off (or an easy way, at least.)

The Ultimate Tool for More Slack Time

Pros

Our company (software delivery solutions company – software industry) has been utilizing Slack for over three years to help both our internal and external teams keep organized. Our team often holds meeting remotely and works with distributed teams, sometimes even in other countries. Having the ability to communicate in one place has shown visible improvements in time and efficiency of getting our team work completed. Slack allows you to set up multiple “workplaces”. For example, we have one workplace we use for our external team and a secondary workplace for our primary, internal team. This helps us keep the responsibilities we share in each team separate of each other. Within each workspace you can create separate channels based on a particular group or topic and invite specific members who pertain to it. You also have a channel that enables everyone in that workspace to communicate within one area and/or you chat directly with one individual from that workspace (which would not be visible to anyone else). Slack’s search features are very helpful and work much like Google. You can also specify your search’s by choosing an individual, date, or key phrase to search for. Uploading and sharing PDFs, Excel, PPTs, etc. is also supported and can be easily shared among others. We rely heavily on Google as our file storage system. The free version of Slack provides you with the option to connect it to your Google Drive account so you are notified, with a link, when anyone share

Cons

Because we are currently utilizing the free plan for a fairly small to mid-sized team we often run into storage problems. When this happens, the only option you have available is to have each team member go in and delete EACH file individually. This is very tedious and time consuming and can take hours to delete 500 files (tip: keep up with it or do searches to make sure you don’t upload the same files that have already been uploaded to Slack). You can also clear more storage by having the admin delete messages from your teams’ shared messaging area, or what we recognize as our case, “general” channel.

Having the ability to look back into your history is very handy. I would strongly recommend the Standard Slack plan for those who have the extra wiggle room in their budget – which provides unlimited search history and app integration.

I currently utilize the desktop application of Slack, so that it is always on my tool bar and easy to access on the daily; however, it prone to timing out when losing internet connection.

Slack Public Channels improves company communication across teams.

It's a great tool, these are the key points for me:
* Improve team collaboration, shared information in a single place and all team has access to the same information.
* Reach people, sometimes you need to collaborate to make things happen, and slack does a great job at that.
* Integrate to CI/CD pipelines, we received notification about or system all time. It's better than having thousands of emails.

Pros

Public channels:
They are easy to create/configure and allow members of the company to share important information in a single place. This is really helpful for software development teams when important information is shared with other application it gets lost and there is no record of it. With the slack channel, the information is stored and can be used as references. (Developers don't have or we don't want to have time to write documentation).

1:1 Message:
What I really like is that is very easy to find people and ping them and start a conversion. Most important, you can share files, photos, URL, gifs (Very important), in a single place. Making collaboration easy and something to enjoy.

Integration:
Slack can be integrated with a lot of third parties. In my case, it's very useful to integrate with Jenkins and code versioning applications. We have implemented CI/CD and we received a slack notification with deploy information, testing information or if a system is down.

Cross-Platform:
Be able to access slack with cell-phone/desktop application is really awesome. If I don't have my computer at hand, I can keep replying messages and collaborate. Especially important when we have a critical bug, or we have to take action.

UX:
The UX is one of the best, you can start using slack with no training, it's very intuitive and easy to use. Once you start using it, you don't want to use other applications.

Cons

Conversion history:
Sometimes the conversion history is deleted after N amount of dates. Probably this is a configuration in my company, but I would like to store more information.

Re-Login:
Once in a while, you have to re-login, but what I don't like is that it logs you out without giving you a warning. It had happend before that the application logs me out, and I notice that one hour later.

If I have Slack, I don't need an email

Overall, Slack has had a great impact on the productivity of my teams. I hold the position of office admin and I manage three teams of Graphic Designers, SEO, and Web-Developers. Everybody is connected through Slack. All the communication is done via Slack. We have stopped sending emails and shifted all the official and formal communication to Slack. It is easy and time-saving to get an acknowledgment of a new office policy and work on a number of other projects.

Pros

Let's get straight to what Slack is good for:

Team collaboration - check
Instant messaging - check
File-sharing - check
Audio/video call - check
Multiple channels - check

Slack is easy to install and work with. There's nothing complicated about it. It is an effective application for instant messaging. What I love most about the software is that it allows creating different channels for different teams. It works as separate virtual offices to manage work more efficiently. Isn't it cool? In Slack, you can let your team members know about your availability - turn on/offer your notifications and when you are bored, you can ask the chatbot to tell you a joke. It is pretty easy to send messages, share files, and integrate other applications such as Google Drive to import documents. Moreover, the Workflow builder and Analytics tools are my favorites.

Cons

I don't know if it is really a disadvantage but Slack is kind of addictive. It has so many options, a cool set of emojis, formatting tools, the bot, and an easy way of communication that it keeps me busy chatting all the time. Oh well, one more thing: in the free version, the old messages keep disappearing. It happened to me a couple of times that I had to check an old piece of information but it was removed automatically. So, be watchful if you're still on the free version and thinking to make a decision on purchase the premium plan.

Slack: The Tool That Sent Email Conversations Packing

The main problems we're solving is to do with communication. Since all our team members are working from the comforts of their homes, we need a place to sync all the time. Slack provides that platform. It's the place we convene and dismiss. Slack feels like home now. Everybody's connected and readily available.

Pros

Slack is one of the tools I didn't care about until I learned about it. And ever since I did, I've come to appreciate its awesomeness. Working in a SaaS company, with a work-from-home culture, software like Slack feels like an Elixr. There are no hassles when it comes to communication... No email. Simply interact and get the job done. The feature I like the most is its Huddle feature for 2-way audio-based communication. Overall, the software is pretty easy to use.
Another cool feature is putting out status (in terms of availability). Whenever I'm AFK for lunch, I put on my availability status, just in case someone decides to reach out. It might sound small, but it works wonders when you're working from home.
Another cool feature is that the messages are saved no matter how long back you or some team member (who might have even left) posted it.
And there are so many integrations possible, which makes it ever so interesting. Playing trivia games daily is our team's one chance to engage in a virtual fun activity space, which is kind of fun.
Also, I've had the opportunity to meet so many people in the various Slack communities. I mean there are other channels, but the quality of the network is definitely right up there.

Cons

Even though Slack is an awesome tool, there's still some scope for improvement here. For instance, even though I mentioned Huddle as one of my favorite features, I've found some of my teammates complaining about not being able to connect, which gets a bit frustrating. Apart from that, there are features to set reminders and put other commands to help manage things better. I wish there was some kind of tutorial available to learn these things earlier. Another thing I wish was there was the ability to put out memes. I mean, I get it... it's a serious kind of platform, but sometimes memes just get the job done. I'd like to conclude by saying that it'd be cool if we could delete our messages (maybe within 5 mins of posting) too apart from just being able to edit them.

The reason tasks get done

I use Slack to manage a High School Robotics team, it is very easy to add, remove, or move members to or from specific channels. We have separate channels for every sub team including Electrical, Design, Software, Scouting, and Strategy. I also use slack as a member of the University of Michigan Rocketry Team (MASA). We use Slack as our main communication source, with over 900 total members on the team, and around 100 active students. This is all done on the free version of Slack, which although has its limits, it proved to be essential in a high stakes project like a 20ft tall rocket. Most clubs I've joined use Slack as their main communication source, so it must be good.

Pros

Slack allows the project teams I'm apart of, the ability to manage their workforce and knowledge. This is usually by communicating issues and meeting notes in a Slack message, which can be discussed in detail in a thread or different channel to maintain the virtual workspace clean. The best part is that anyone on the team will acknowledge the message, but they can choose to dive deeper into the topics addressed in the message if they want to through the use of channels or threads. This helps us manage the levels of interest on the team, something that other software wouldn't have allowed us to do.

Cons

There aren't any restrictions on censorship or age that could be applied to specific channels or members. I have no way of ensuring that other students don't post inappropriate messages or pictures without other students seeing them first. I'm not sure what this restriction could look like, but it's a concern because I'm not monitoring the channels 24/7. Another concern is that anyone can view any channel, whether they have joined it or not. This makes it difficult to communicate information for example, between two teams on the same slack.

Best collaboration tool to use between your teams

Before being compelled to work from home in a distributed and asynchronous environment, I didn't fully appreciate the quality of Slack. However, when faced with the challenge of working remotely (and juggling kids' schooling from home), Slack has proven to be a valuable upgrade from traditional emails and other online collaborative tools. With Slack, I have access to a one-stop-shop that allows me to receive notifications for Google Doc edits and respond to them directly from the platform, saving me a significant amount of time.

Pros

Slack offers a straightforward and effective interface for inter-team communication, elevating communication beyond emails and Facebook messages through a secure platform that caters to teams. Among Slack's standout features are its channel setup, which enables the creation of focused spaces centered on specific topics, and the ability to reply to individual messages within a thread. Channels help maintain my team's focus and keep them on track, while also providing a casual space for informal conversations (via our "Random" channel). Meanwhile, threads help prevent channels from becoming an overwhelming, jumbled mess. Additionally, Slack's ability to react to messages with emojis, share messages with specific individuals, create private or public channels, and send group messages to team members creates an environment that encourages collaboration and communication in a way that feels organic and intuitive. In summary, Slack's platform provides an uncomplicated, natural space for teams to work together and communicate effectively, replacing traditional text threads, Facebook messages, and emails.

Cons

While Slack provides a centralized tool for online collaborative work, the learning curve can be somewhat challenging due to the non-intuitive nature of shortcuts and integrations. Additionally, subscribing to multiple Slack channels can be overwhelming and result in an excess of notifications that may prove distracting. However, this is the trade-off of having a singular platform for all collaborative work.

Slack Simplifies Team Interaction

Pros

I've constantly sought efficient methods to streamline communication within my team. Slack has been an absolute game-changer in this regard, offering a platform that facilitates quick, organized messaging like no other.

One of the standout features of Slack is its simplicity. Within minutes of setting up, I was able to create channels for various projects, departments, and even casual discussions.This compartmentalization ensures that conversations remain focused and easily accessible, eliminating the clutter and confusion often associated with email threads.

Cons

The restriction on attaching only nine files at a time can be a slight inconvenience when sharing larger batches of documents. Nevertheless, Slack's plethora of features, including organized channels and seamless integrations, make it a top choice for enhancing collaboration and productivity within any team.

Slacktopia: Simplify Your Interaction

Overall, I've had nothing but great experiences with Slack. It's a really helpful platform for project management, teamwork, and communication. It is an invaluable tool for increasing productivity and encouraging teamwork because of its user-friendly interface, wide range of customisation options, and smooth connection with other programmes. But sometimes it might be difficult to handle notifications and information overload; it takes careful planning and moderation. Slack is still a vital tool for contemporary workplaces in spite of this.

Pros

The best thing about Slack, in my opinion, is how easily it integrates with different communication channels and has an intuitive UI that makes it simple to share files, remain in touch with coworkers, and work efficiently in real-time. Its extensive app integrations and customisation possibilities also improve productivity and simplify workflows.

Cons

Slack's potential for information overload, especially with regard to channels and notifications, is a disadvantage that can occasionally result in decreased focus and distractions. Additionally, without appropriate planning and communication channel control, managing big teams or complicated projects can become difficult.

Great collaboration platform

Slack seems to been the best collaboration currently available

Pros

Simple to install, setup, and use for an organization of any size. They continue to enhance and improve. The search capability is very slick and the option to save a message for quick find later is great. Easy to organize channels and direct messages into groups. Has a lot of add ons which help integrate with other tools within a work environment. Great documentation and community support.

Ease of management is a highly desired feature, which slack provides. Collaboration options like audio/video calls, file sharing, screen sharing, ability to select which screen/desktop to share, and group calls are amazing features which work really well

Cons

Nothing that stands out other than occasional bugs which get addressed soon. Some apps send notifications even after they are muted.

Slack: Transforming Team Collaboration in the Modern Workplace

I must say, I've had an incredible experience using Slack! The interface is so easy to use, and with all the collaboration tools and integrations, it's definitely improved our team's productivity. And let's not forget about the security features - they're top-notch! Honestly, Slack has completely changed the game for us. Communication is effortless and teamwork is seamless. If you're looking to boost collaboration within your team and streamline your workflows, I highly recommend giving Slack a try!

Pros

Slack has revolutionized team collaboration with seamless communication, organized information management, intuitive collaboration features, and powerful integrations. The ability to customize notifications and the accessibility provided by the mobile app further enhance the overall user experience. As a user, I am impressed by how Slack has transformed how my team communicates and works together, boosting productivity, efficiency, and overall success.

Cons

Despite its numerous strengths, Slack does have a few areas that could be further optimized. The learning curve, notification management, file organization, and search functionality are aspects that I found to be slightly challenging. However, it's important to note that these limitations are relatively minor compared to the overall value and benefits Slack brings to team collaboration. With its ongoing updates and commitment to user feedback, Slack has the potential to address these concerns and continue to evolve as a leading collaboration platform.

Slack as a virtual Workspace

Overall it is excellent tool for communication. I did not explore more complicated features yes, but so far, on the basic level, the functionalities are flawless, and, most importantly, it is easy to deply, easy to learn. Some of my employee are not technologically savy, dont like learning new apps of softwares, but Slack was implemented practically without problems. I tried the pro version, but for my needs it did not differ from the basic plan.

Pros

I moved all my communication, file sharing, project managing, discussions inside my organisation to Slack. It was motivated by the price, accessibility, ease of deployment, and great, impactfull features like threads in communications and bookmarks for file sharing. Real time synchornization also played a big part of my decision. I check about 10-12 different software before deciding on Slack and it was one of the best decision for my workflow.

Cons

Some of my employee complains about temporally losing access to Slack, but I personally never experienced something like that. Nevertheless it can be frustrating, when all my communication is done by Slack and some employee can't log in.

Alternatives Considered

Workplace from Meta, Zoom Workplace and Hive

Reasons for Choosing Slack

Firstly, price. Secondly i had a lot of problems with Teams - with functionality, acess, deployment, implementation, integration. Searching through conversation in teams was painfull, and file sharing was a disaster.

Switched From

Microsoft Teams

Reasons for Switching to Slack

I needed something that will be easy to learn for my employees. I have frequent rotation of employees and i dont have time to teach new employees a software. For me software must be self-understood, intuitive. And Slack is exactly that. I consider this its biggest advantage - after installing Slack all my employees intuitively know what to do, what to click. Price also played a role, but not first and foremost.

Wonderful and Colorful Communication Application

Slack has been an essential communication tool for our team. It has been very effective at keeping us more connected and working on issues. Administration of the application doesn't take to long to learn.

Pros

The chat feature keeps our team connected across many locations we service. The huddle feature allows us to easily speak to each other in conferences and collaborate. Slack has a lot of features and options we can configure specifically to our needs. It has a nice layout that keeps users engaged. We are able to setup our alerts to notify us in slack channels and keep our NOC team aware of real time issues.

Cons

Slack does not integrate with Microsoft Teams and some of our clients are unable to chat with us. File size restrictions make sharing pictures and screenshots frustrating to open. There are no language and parental monitors.

Alternatives Considered

Reasons for Switching to Slack

Slack had better integration with our team and clients. We are able to have external channels with our clients that use Slack and speak to them in real time chats. The cost for Slack was better than Microsoft Teams.

Not bad for small groups, horrible for large groups, free plan is now crippled

Only using Slack with external teams that use them. We no longer use it with our internal teams. Their confusing threaded views is really their downfall. There are other alternatives out there that do a much better job.

Pros

Slack has a very nice, slick interface. When the workspace is not busy, it's very easy to see all the messages and figure out what's relevant for you. Very easy to setup new workspaces and channels. And basically, the key reason why we use Slack is because almost everyone is using it.

Cons

Their free plan is now crippled. Only 90 days of retention. On a number of free workspaces, I wanted to refer back to some info which I no longer can find. Very frustrating. Slack also implements threaded conversations as a "tack-on" feature. Not everyone uses this feature and it just causes more and more user confusion, especially in large workspaces where many messages are mixed into the main channel as well as in threads. Their threads/mentions&reactions views which are supposed to help you filter out things not relevant for you are huge messes. Their pricing plans are also very expensive.

Alternatives Considered

Mattermost, Zulip and Microsoft Teams

Reasons for Switching to Slack

We're no longer using Slack internally. Only for external communication with teams that insist on using it. MS Teams offers better integration with their Office suite. Zulip offers superior threaded conversations and formatting at a much more reasonable cost.

Great Tool For Organizing Communications

I cannot over emphasize the need for clear and consistent communications, especially when working with a team that is frequently spread out over a region. It keeps our flow and processes moving smoothly and makes it very simple to reach out and chat with one another through out the day. I feel like Slack is a valuable addition to our company.

Pros

The ability to customize channels and lock them for management conversations versus daily chatter has been an absolute blessing. This makes it so that our team knows where to go to result on their day, drop a marketing idea, or ask a question. The 'slack bot' is especially helpful in auto timing a nudge for sales results from the team or nudging managers to drop topics for the next meeting.

Cons

Integration was simple, setting up is easy. It's as natural as texting or using messenger. The channel lay out can look a little messy, I wish we could nest it down a little. Otherwise, I have no complaints. The free plan and the paid plans are fantastic - we have used both.

monday.com and Google Meet

Reasons for Switching to Slack

Google Workspaces, Meets and Chats feel scattered. The information is laid out like a computer desktop. Sterile and not intuitive at all. Slack is set up in a format that is similar to the messaging and emailing platforms we are already used to without a bunch of extras in the way. On top of this ease of use and adaptability, it remains simple. There are no extra features getting in the way, no constant upsells. It fills the need perfectly without slowing anyone down.

There cannot be a better way to communicate among teams than Slack. Slack has made our lifes easier since we have been working from home remotely from different parts of the globe but stay unified and connected with the help of this tool. They also have a mobile app that lets you access all your chats and files on your phone. Its a great tool for every organization.

Pros

We have been using Slack for almost a year now and all our departments love it. It is a great way to catchup internally within teams or also coordinate with cross functional teams. We use slack for daily followups and project management and task tracking. The IT department of our organization also uses Slack for bug tracking and remote work. Team communication is now just a click away and we feel connected with Slack.

The Best Communication Tool for Business & Also Easily Misused at an Organizational Level

Ultimately, I gave up Slack in my own organization and only use it when clients add me to their accounts. The ability to have task-related conversions in Asana is initially where I migrated my team off of Slack.

Pros

I love the immediacy of the tool. The ability to hash out a conversation entirely online, grouped by subject matter with the exact amount of people you need to be involved on a team. The price is a dream since there is full functionality with a free account as long as you don't need access to older files. When the Slack interface is set up well for an organization, it makes department-wide communication effortless.

Cons

Since each user tends to have different communication styles, organizations that don't create frameworks and guidelines around how their organization uses the tool devolve into chaos. I've had clients who have a beautifully streamlined tool that functions in a way that serves their business and other clients who have let the tool become a complete distraction to their workflows.

I LOVE the digital workspace that Slack offers. I don't know how any company would be surviving in the pre-Slack era. Slack is extremely easy to use and has instant messaging, video calling, voice calling, screen sharing, file sharing and integration features that makes it a boss of professional digital workspaces of the remote future of work.

Cons

There is absolutely nothing to not like about Slack today.

Great Team Communication Software For Anyone Just Starting out

My overall experience with Slack has been alright. I loved the communication features and the fact that it was perfect for my team and I when we were just starting out. It really gave me the power to start my team even though I didn't really have the budget for a centralized communication software for my business at the time. The ability to coordinate and communicate with me team in real-time, as well as guest freelancers and others was great. It served us very well for the time that we used it. I would highly recommend this software to anyone who is looking to get started using a multi-person communication software for their team. If you are looking for something that is geared more towards focusing on tasks and project management as well as communication, I would recommend looking into something different.

Pros

The great thing about Slack is, first of all, it has multiple pricing plans. Especially, the fact that its first pricing plan is completely free. So it is great for anyone who is just starting a team, whether it be for a start-up for either a non-profit or a business. You have the ability to share files, communicate in real-time, receive real-time notifications, and communicate with multiple people at once. As well as do some small project management functions.

Cons

The only shortcomings I would say Slack has, is the fact that they are obviously a software that is mainly built for the purposes of communication between people in real-time. More like a glorified messenger app. So the file sharing, collaboration, and other project management features leave somethings to be desired.

It's a great Communication tool and the pricing is fair!

We felt that we made the right move by switching to this pro tool. Our communications it's very effective, and there is no mistake in mixing private or personal communications. This helped our team to stay focused and always reply in business mode.

Pros

We are a marketing agency and have several types of contracts and clients who love fast communications and avoid long email threads. We cannot live without it.

Cons

We are glad that restrictions for free accounts were removed, which allow new adopters to get to know the tool better and incorporate it into their daily activities.

One of the best essential tools for many departments

Pros

Being able to control channels by managing team members on each channel is helpful. It also lets us connect with external slack (companies) and easily communicate with third-party companies with ease. Switching between organizations is a breeze. I can be able to open up multiple slack apps throughout many computer systems with the same credentials is also a huge plus.

Cons

I have not found one yet. All the features are quite satisfactory.

Slack: The Bridge Connecting Colleagues With Effective Communication

While Slack is not extra-ordinary, it certainly is reliable. Its quick communication is the most attractive thing about it. If the problems are fixed, then it can do so much better.

Pros

Slack is a holistic platform which allows to integrate with other office tools and spaces. The best part about it is that one doesn't have to check their mails often. When your workplace is virtually available on Slack, 24*7 updates are available on a simple notification. With detailed notification settings, one can also choose to appear offline/away after office hours. Another good thing about it is, Slack is neither too personal nor to formal. You can chat/reach out to any member of the company at any time without having to worry if you are disturbing someone or being too informal in doing so. The reminders for meetings and special events eliminate the need to mark them personally on a calendar. All in all, Slack is the ultimate interface every organisation needs.

Cons

One of the things that needs improvement is the audio-visual quality of the video call service of Slack. That really needs working. Apart from this, Slack can be a little confusing with many channels that one has to navigate through. Channels are like sub-groups within one common platform. Too many channels can sometimes create confusion and miscommunication. Another problem would be its limitation of working smoothly only on the app. It often runs roughly on Chrome or any other browser.

Slack Review

Slack has been a go-to team meeting and chat platform at different positions and also during communal club spaces for organizations, such as the graphic design organization AIGA, which I frequent within my local design community. I haven't had any major issues with it thus far ans can easily recommend it. Being a business-focused chat space it also does not have silly loading messages like Discord which I've also used and which also worked well, but felt a bit unprofessional at times.

Pros

Slack is an easy to navigate, light on hardware platform to facilitate teamwork. You won't need a top of the line computer to run it so even in remote work conditions you will reliably have it available. There are not excessive features to get lost in or particular issues finding your team meetings constantly, a code to the overall Slack channel is sufficent.

As opposed to other productsused for video conferences such as Zoom, everything is built in on Slack for "one stop shopping" using the program. It allows for image uploads and other useful tools such as split channels for specific tasks like designating a set of crew members to a task in a server,

Cons

The user interface is readable but slightly bland with the entire white color scheme. It's not strictly necessary but it can be difficult to only look at that color scheme for when you use it, other programs like Discord have variability.

The best option for chat and communication

This experience has been very satisfying with minor hiccups.
Slack is the best option for chat and communication in a work environment.
I'm the office manager for a law practice.
I'm handling files that shouldn't be sent through unencrypted SMS or social media, clients won't be happy with us if the entire world finds out they've filed for bankruptcy.
Slack is very similar to those, it's just better structured and more secure to use for work.
It couldn't be more convenient or any easier. I open Slack and I literally have everything in front of me. Tap once or twice and I'm in the right discussion, another tap and I'm looking at my co-workers face to face.

Pros

Slack couldn't be easier to use, I had mastered everything in a few minutes. There are several levels of communication. The first is Slack as a whole, then channels or topics, comment threads inside the channels, and direct or private messages. Video conferences or Slack huddles couldn't be easier and they're started and kept within Slack. Audio and Video clips can be sent in place of holding a real time meeting and watched at any time.
This is very secure.

Cons

If Slack isn't kept in check all of the channels can get overwhelming and hard to keep up with. I have to make sure unused channels get deleted or moved.
I think the price is a bit ridiculous and the version you get for free is a huge step down from the Slack pro version. Slack pro is on sale frequently but the promotions usually only last 90 days and can only be used once.
The other problem is the messages not being saved. We've all been really irritated with that at some point.

Generally, experience is very useful and helped in sorting out the group correspondence quite well. Professionals: The best thing about slack is group cooperation and correspondence. The gathering and classifications in view of the subject are very great and help in the isolation of content in light of need. Also, it is very organized and easy to communicate especially in posting in thread.

Pros

Slack assists you with talking and communicating with specific individuals and groups inside your association or different associations with Slack rapidly. It likewise allows you to track all that individuals have said about a thought so you can look by catchphrase for a particular thought. I love it. I use it consistently, and you might actually say it's the collective conscience for the association. It's such a ton lighter than an email client, and I want to do my help tickets with different associations with it(honestly, there's likely an application for it out there). This leads me to another incredible point; Slack is perfect for rapidly imparting thoughts and coordinating a few applications. Pretty soon, the association between SF and Slack will improve, I'm certain. Your association needs Slack in the event that it can manage the cost of it. It is priceless for diminishing the time it takes to team up and use aggregate insight.

Cons

Allow me to begin by saying you're likely not going to find anything better than Slack. These reactions are enhancements to the item I think ought to be made however are in no way, shape, or form a legitimization for why you shouldn't utilize this. Email is killing your business by making you and your group sit around idly. My one test with any undertaking application is that it can get somewhat hard to figure even to design every one of those settings(email is more awful at this than Slack). I wish that settings were suggested in view of the use of highlights inside the application. Kindly assist me with figuring out how to involve Slack in additional useful ways. Kindly don't make me swim through help articles and directions. All things considered, put the button to switch the setting in a pop-around directly in the center of my work process or in a notice on Slackbot so I can roll out the improvement there and see the reason why it will assist me with being more useful. Warnings are difficult to make due, however, they're getting better at that. Simply realize I'm suffocating and would cherish a component worked in that offered the response to FAQs by utilizing some ML(apps that do this are too costly on the API to be worth the effort). I'm a well-informed authority and get pinged with a lot of DMs and's in channels that basically have similar responses. Assist me with volume so I as a solitary individual can help more individuals. Some something to think about. Also, they

Pretty great way to connect with your team

I really enjoy using Slack to connect with various groups and individuals I need to interact with both inside and outside of my work organization. Adding additional connections outside of my organization is easy and then gives me access to all work-related communications inside the app I already use for work communications. Very convenient!

Pros

It's easy to set up new workspaces, and once they're set up you have an easy way to connect with all the people you work with simply and in either a synchronous or asynchronous way. This is especially helpful when connecting with people from multiple timezones.

Cons

Video calls are pretty resource-intensive so it's sometimes hard to do such things as share your screen to demonstrate a problem you're working on. Furthermore, those controls always get in the way of what you're trying to do. It would be nice if they could be minimized into a floating button, or something, that you could move out of the way until you needed them.

This App doesn't Slack

Slack presented me with a simple solution to the communications challenges that come with project and office management. I started using it initially to manage an office, while in my early years of running a small office. We could streamline communications, tag persons who needed to get into a conversation, and we used their threading features to ensure that we could manage different conversations, all at once.

That beat the use of Blackberry Messenger which we had been using earlier. When Whatsapp came on the scene, and people suggested we use that, it beat it by far as well.

Slack was the best at keeping us on track, and it eventually allowed us to search channels which meant that we could now go back to previous discussions to help to keep track of things. Those two features sold me on the platform.

I'll admit, when Microsoft 365 launched Teams, I ventured away from the hallowed halls of Slack, much to the chagrin of many. The thing is, I've passed the stage when I could stomach moving from platform to platform, login to login, bill to bill to assemble the best combination of everything.

That aside, one needs to acknowledge that the Microsoft apps aren't the best in most of their fields (except Office), but they are pretty good.

In this area, Slack is the best. They may have named it Slack, but they do not Slack at all.

Pros

Slack is best-in class for project communications, and keeping your communications on course. They innovated in creating the platform, and while others may do well with one part or the other, they are the real macoy. All others are just trying to copy them.

Cons

While their api opens Slack up to combine with other platforms, I really wish they had more native features.

Slack - business communicator for everyone

I was using Slack in various companies throughout my career and I have to admit it is the best business communicator I was using. Its design is intuitive and incredibly easy to use. During Video Conferencing the video is usually clear, the same as the voice. Messages and updates are delivered immediately. Some useful features like reacting to messages, a three-dot icon indicating that someone is writing, screen drawing during screen-sharing, or custom emotes make communication faster and more personal. There are also, a lot of additional plugins that allow different actions inside the app. Real-time notifications from external tools (like Jenkins), the possibility to create Jira tickets directly from Slack, or reading documents from Google Drive are only some of the options. The application can be tailored to the needs of different companies, so it can handle different tasks depending on the company.
The only flaw I can think of is the fact that Slack can become pricy the more users are using it. Because of that, some firms can seek a cheaper alternative.
All in all, Slack is the best communicator I was working with. Its ease of use with a lot of functionalities made my work communication easier, enjoyable, and more personal than any other tool I was using.

Pros

Intuitive design.
Easy to use.
Great mobile version.
A number of features and plugins.
Possibilities of customization.

Cons

For some smaller companies, the price can be too high.

The chat app for developer teams that is a pleasure to use, when connection issues don't...

Slack is the de facto chat app for developer teams. Although with some rough edges here and there, with Slack we were able to easily integrate existing and custom solutions that helped us better keep track of what is happening in the team and with the projects.

Huddles are also a great way to communicate, as we were able to talk with the team any time, making our workflow and sharing experiences easy.

Pros

The interface is easy to use. Everything is laid out in 2 to 3 columns: the sidebar with all the channels and contacts, the main chat column and an optional third column for viewing threads. This way, you can always focus on what you/other are trying to tell. The message box is a pleasure to use, as it allows writing formatted messages easily; and sharing files is as easy as drag and drop.

Threads, although I was a bit against it at first, help branch some conversations so you or your team can add details without breaking the main conversation.

Huddles are also a great way to real time communication. They allow teams to communicate easily, like we were in a room in the same place, where anyone can join and leave at any time, without depending on others.

Finally, the API is powerful. Although a bit complex at times, integrating custom apps and workflows allows expanding the knowledge of the team at any given point in time greatly.

Also, the music that plays when waiting alone in a huddle is a good bonus.

Cons

Communicating outside messages is a little bit confusing sometimes. Slack has two features, huddles and calls. Huddles are for quick audio communication while calls are regular calls with video support. Both (sometimes) do their job well, however, it is confusing when to use one or another, as both have overlapping features but implemented in different ways.

Connection to Slack servers are also an issue. Calls suddenly drop or audio lags heavily, messages take a lot of time to send, and the macOS version sometimes hangs without response, forcing the user to forcefully exit.

Finally, forwarding and sharing messages with other teammates is sometimes complex, as there are two ways to do this, and both don't work when you expected to.

Multifaceted Messaging

Some employees are not in the facility for most or all of the day. Slack helps me monitor everyone and is a way for us talk throughout the day. Employees working together or in rotation use slack to stay in touch too. In the morning we get everyone in a quick video conference to plan for the day and update. It's worked well.

Pros

I can create message channels and control or monitor who is in each, settings can be changed to public or private. Individuals can message privately too. I like how the channels are displayed I can find any of them quickly. Video calls can be created without leaving the messages screen. I can usually see and hear everyone clearly.
Links open in the app and when I send photos and videos all load quickly.

Cons

All of the messages aren't saved and I wasn't able to find a way to change the setting. I have had to save folders full of screenshots incase important messages get deleted.
More value for money and less taken out of the lower price tiers would make Slack better too.
