A great team communication tool

Slack is honestly the best tool for team collaboration. You can communicate via voice or text with your coworker or friends from the browser, desktop or phone and it's reliable a lot. The messages are there and so are the files shared. Also same with the chat rooms.

Pros

I like Slack. I have been using it for aprox 4 years now. It's simple and it get's the job done. You can add extensions like JIRA, Google Drive, DropBox and so on. Basically slack you can have different rooms for different teams (you can manage the members per room or invite) and you can also have private chat conversations with other people. It's basically a chat server for your company or organization. The mobile app is awesome, the desktop app is fine and you can also use Slack on the browser. The free tier is good if you have a small team, now if you message a lot there's like a 10,000 message limit for the history so if you want to get the best deal, you'll need to pay. Same for the file sharing, there's a limit but it works super good.

Cons

Honestly Slack is great, but with the time, it's become stagnant. A lot of other platforms are providing features that are more robust and free. For instance, Discord, even if it is for gaming, it does everything Slack does and better. Even the desktop sharing is better. I wish Slack just kind of moved out of the stagnant position they are right now and innovate a bit more or refresh their app, but hopefully they don't break it, because it works fine as well.

Reasons for Switching to Slack

I initially started with it, before Discord even got better, the thing is, we are so integrated with Slack at the moment, we wish Discord could just add extensions but they have bots. so they're almost there.

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.

Awesome Business Communication Tool!

I have enjoyed using the application. I like how it can be installed on both my phone and tablet as well and easily sync and take calls on either devices.

Pros

1. I like how sending messages to teammates is effortless2. I love the huddle feature as it's quite helpful in aligning on goals.3. I enjoy the customization of the application in terms of notification sounds, themes etc.4. I like the ease of use of the application.5. I like the dark theme as it's a lot easier on the eyes.6. I like how you can attach various forms of media and send them to colleagues.7. The capability of making channels private.8. I like how you can schedule messages that automatically get sent a bit later.9. I enjoy how close it makes colleagues feel even in a work-from-home setup.

Cons

1. The pricing is a bit steep2. I wish it had better huddle and video conferencing capabilities. 3. I wish they could be rolling out updates and new features more often.4. I hate how when choosing an emoji the emoji tab disappears and you need to click again to bring it up. 5. I hate the display picture feature whereby a picture can come up as all messed up when uploaded.

Communicate and Collaborate in real time

Pros

It enhances the process of collaboration with in teams that is real-time. It also allows a lot of apps to get integrated such as Google Drive, Trello and Salesforce.

Cons

It can be slow at times and for the first time use, it can be overwhelming for a user. It is also an expensive tool and should be thoroughly analysed before finalising.

Teams can hold virtual meetings, conduct audio conferences, or have face-to-face discussions using Slack's built-in calling capabilities.Screen Sharing: Slack's screen sharing feature allows users to share their screens with teammates during calls or even within channels. This functionality is particularly useful for presentations, remote collaboration, and troubleshooting.App Directory: Slack has an extensive App Directory that offers integrations with numerous third-party applications and services. These integrations enable users to bring data, notifications, and actions from other tools directly into Slack, making it a central hub for productivity and collaboration.Workflow Automation

Users can send messages to individuals, groups, or entire teams, facilitating easy and immediate communication across the organization.Channels and Threads: Slack's channel-based communication structure enables users to create dedicated spaces for specific topics, projects, or departments.

Additionally, threaded conversations within channels allow for more in-depth discussions without cluttering the main conversation.Notifications and Mentions: Slack's notification system ensures that users stay informed and engaged. Users can customize their notification settings to receive alerts for mentions, direct messages, or specific keywords. This feature helps ensure timely responses and reduces the chances of missing important information.File Sharing and Collaboration

My favorite Business Messaging App

Slack has become my favorite internal chat software! It's simple to use, you can sort the communications by open and closed groups, highlight words you don't want to miss, tag people, voice, video and screen huddle, use emoji and more... As someone who is typically active in groups or in chats and want to keep it fun, I love that you can upload your own emoji, allowing you to have more realistic reactions in your chats. I'd definitely recommend slack to organizations.

Pros

Voice and video huddles, they're great if you need to have a quick 1-on-1 or a quick team meeting and don't want to send invites to everyone via Zoom or Google Meets.

Cons

Honestly, I can't complain, Slack has been a very accessible and reliable tool whenever I've had the chance to use it.

Perfect for our company's communication!

Pros

Slack offers the feature of creating several channels/groups with specific people. This is incredibly helpful when sharing information that just needs to be sent to a group of co-workers. It is also quick when sending direct messages, and allows you to attach files such as images, files, and videos. The desktop and mobile versions are so user-friendly and easy to use that you won't need a tutorial to learn how to use them.

Cons

I would love to be able to change the notification sound and customize the colors of the interface.

My most used tool

I've been using Slack for almost 10 years and it's impressive to see how they have grown.

Pros

I use Slack all day long for chats, but also for meeting notes, for knowledge base, for calls. I like a company better if I know they use Slac.

Cons

I get caught by surprise when they make major changes, I wish they would give heads up. If they do, I wish I know how to see what they are about to do.

Best Collaboration Tool Available!

Slack has been wonderful to use both professionally and personally. I have managed multiple cross functional projects utilizing this tool to gather the most recent information needed for status reports, metrics, check-ins etc. Personally I use it to collaborate with my Agile Coach friends across the globe to share tools, tips and tricks we use while supporting our teams at work. We also use it monthly during our zoom meetups to chat amongst ourselves and share info during the call etc. I highly recoomend this collaborative tool.

Pros

I LOVE that you can create your own channels to keep conversations and shared documents organized and easily accessible for different groups you are collaborating with.
I also LOVE that these channels don't expire and can be accessed by anyone across the globe that you are collaborating with. This has changed the way collaboration can happen virtually in real time!

Cons

The # hashtags can cause me issues when I am searching for things but I am starting to get better at using them.

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.

Alternatives Considered

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.

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.

The only way to communicate within a team

I use it for all manners of communication with my team - from quick huddles when we get stuck and need a rubber ducky moment, to bigger team meetings. We have groups for smaller teams to collaborate in, we have fun channels to blow off steam, and we even use it for the food train organization.

Pros

It is easy to use and feels natural. For us coming from Discord or IRC, it is very intuitive to understand how to use it without any learning curve whatsoever. Slack helps me connect with coworkers, share project updates, send cat photos to my team, send random funny quotes, gifs, reactions, all of it still in a very professional application that handles all of my communication needs.

Cons

Slack sometimes becomes too much, but it is easy to mute it to focus on work so this is easily solveable.

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.

Cons

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

The best chat application.

Slack makes team communication easy. I use it to send updates to team members, build relationships with team members (it's funny how much team culture and unity can be built on a strong foundation of memes), post polls, gather feedback on internal projects, get quick answers to quick questions, etc. Slack makes it easy to integrate, so I've used third-party integrations like HeyTaco for employee recognition. Slack makes it possible to do a significant portion of your work out of a chat app.

Pros

Slack has by far the best UI, the best organization, and the best set of features. Competing products like Google Chat (the business version of Hangouts) don't even come close. The most critical feature is being able to simultaneously log in to multiple Slack instances which each have multiple rooms, groups, etc. Slack makes text-based communication super easy.

Cons

It's pricey in comparison to some of the competing software (especially if your organization already uses G Suite, it may be a hard sell to move to Slack). Also, Slack literally makes me more of a slacker - it's too easy to BS with coworkers or members of other non-work-related slack groups when I should be working.

Slack is an easy communications package for everyone

An excellent tool that has helped numerous businesses I have installed and suggested it for. Most slip straight into using it and find very little barrier to entry; in short order the app has become default communications platform for the organizations I've set it up in. I've seen the opposite in other organizations I've worked in or for - other platforms did not experience the pickup at all. Slack is very usable and intuitive in its interface. Well recommended as a communications platform for organizations.

Pros

Slack is very easy to pick up and use. Most people are used to some form of online chat or comms and Slack is familiar in short order and easy to work your way around. Most of the functions you expect are there - able to upload files, etc. and the integration with Google Drive is an added convenience if you use Google Suite. Notifications are easy to manage which is important when you have a large group using the app as they can come thick and fast and being able to turn them off, especially if you have it installed on mobile, is very necessary.

Cons

The interface is fairly vanilla and unassuming. It could do with an overhaul and some options for adjustment. When you have the mobile app, if you have a large group of people using it the notifications can become very disruptive. Fortunately, the options to switch on Do Not Disturb or to log yourself Away between certain hours are very helpful.

Slack: Communicate with Flair

Overall, the platform has been the best out of several team communication applications. This had a much easier sense of user navigability and user experience with its sleek, modern look. It also had the capability of customizing your profile to an extent, with being able to add pictures, a bio, as well as static and dynamic emojis. It also had a unique gif feature that allowed for the posting of gifs but being able to randomize them. So essentially, typing in a random word would net several options of gifs, some of them quite unexpected and hilarious. This provided a good amount of entertainment for the younger crowds in the office.

Pros

The app and website had a very modern feel to it and relatively easy to navigate across. There was a section that provided what slack calls channels that usually was filled with members of certain teams or company-wide channels where messaging would go out to all these larger groups. Below that, there was a section that was dedicated toward smaller group messaging between coworkers or between individuals. The program would also keep your most highly used personal channels between groups and individuals pinned for easy access and these channels would contain the entire history of the conversations so it was very easy to find a particular message from someone if you were looking for specific information.

Cons

The notifications would be intrusive at times, so if you didn't turn off your notifications there would be large messages coming across your screen with a resounding ding that would announce the message. It would also preview a bit of the message being sent, so if you were having a particularly private conversation, there was the possibility of that popping up across your screen for others to see. It would be easy to forget to turn this feature if you weren't constantly running into meetings, but it seemed like this was an issue in terms of keeping things private.

Slack is an exceptional communications tool for teams of all sizes. I highly recommend it.

Pros

Slack was built with a very powerful software architecture in mind, yet so many individuals can use it because of its friendly user-interface. The design is very fun, playful and gives you the powerful functionality that you never thought existed. For how many use cases there are in Slack, they make the user experience very streamlined and easy to pick up. In addition, you can sync a lot of the other programs that you use with their integration features.

My favorite is the ability to keep up with internal conversations based on the topic. I personally dislike being in group chats where the conversation isn't relevant to me. It can be of annoyance receiving notifications that don't pertain to your role and you have to check and delete at a later time. With Slack, their channels can be very specific and allow you to pick and choose which ones you want to join.

Cons

The biggest takeaway is if it's not used right within an organization, it can be a productivity killer. Slack connects to both your mobile device and your laptop so if you do not manage you notifications right, it can be virtually impossible to escape the conversations that are going on. Saying this, our team implements certain hours of the day where ALL phone and laptop notifications are off. Slack makes it possible to do this by changing your modes of availability and/or snoozing the notifcations for certain periods of time. As long as you limit the amount of channels to the ones that require you rattention and don't spend your whole day falling in the trap of checking your notifications all the time, it can be an awesome tool for communication.

This is the new way to communicate online

I use Slack for daily communication business and to stay connected to coworkers and suppliers distributed among different locations. We have implemented Slack as a missing link that smoothly makes working with people on the other side of the country as if they would be sitting in an office just down the hallway.

Pros

Slack is simple, it is easy to use it has a lightweight user experience thus, at the same time is very powerful. In day to day routines it is just a great way of communicating (chatting) with coworkers. Perfect, reliable, fast asynchronous communication. Then someone tells you something you need to remember next week- use integrated reminders, that send you a message when you need it. Or you want to share your desktop real quick, to sho someone something in order to get their opinion. Slack has you covered. Or have a video call with someone or even a group of people. There you have it. Share files ? No problem. Want to have your conversations deleted after a while. there you go. The most impressive thing about all this is the simplicity and ease in which these features integrate into the core functionality which is a chat. Bravo !

Cons

Some of the features seem - behind the scenes - not optimized allready. Sharing data from my mobile device require it for example, to be uploaded first and then downloaded to the recipient. It works, but it takes more time and, I don't care when it is on the server I only care for it to reach the intended recipient(s). Synchronize it to the server whenever its suitable. Connection and reconnection gets tangled up sometimes, with Slack insisting that there is no connection available although all other applications have reconnected already. This however is complaining on a very high level, as these issues are really minor compared to almost all other platforms for online communication I have used.

Quick, Organized Messaging and High Functionality

Despite the time it took to get accustomed to the software and the constant teaching we have to do for new members of our team on how to best use it, I'm so glad that we switched to Slack. It works for us because we have minimal use for emails and are frequently messaging about things that require quick responses from many people. I have only used it on a team of 40+ people for part-time community organizing, not a full-time job or project, but it has reduced so much stress and greatly increased our productivity and communication. Plus, we can have separate channels just for jokes or recipes, so it adds a fun element to our work without ONE MORE EMAIL in everyone's inbox.

Pros

Slack helps our team of 40+ people stay organized and on task. I'm not an early tech adopter, but I LOVE having my email inbox NOT inundated constantly with various subjects and to-dos. In fact, we never use email for our team, with the exception of occasional messages that come in from someone outside of our organization that we all need to discuss (and even then, copy and pasting it into Slack often yields better results and responses!). Slack has the level of organization (through both separate channels and also individual threads/discussions within each channel) that email lacks, with practically the ease of texting if you are using the phone app. Within the computer app, the separateness of the software from a web browser minimizes distractions while working within the app, although it does require switching back and forth between the two if additional info is needed.

Cons

Slack does have a significant learning curve, especially with all of the special functions that are possible within the app; our team uses very few of the special functions because they aren't immediately intuitive and we haven't taken the time to get trained on them. Channels can get cluttered quickly if threads are not utilize properly, and it can take time to scroll back through the channel to find posts (although there is a search function). Also, it's a small thing, but we use the emoji "reaction" function regularly to post Yes/No questions, vote for approval on proposals (Thumbs up!), etc., but Slack does not currently notify posters of emoji "reactions" to their posts; they just have to go to the app to see whether anyone has responded or not.

Slack - Fastest way to communicate internally!

Overall, Slack is a communication king. It acts as a one tool for all and seamlessly allows multiple integrations with so many third party applications. All of its content are searchable, pinnable and configurable to your personal preference. Slack makes file sharing easy across all conversations and is available for across multi platform.

Pros

Slack is a communication tool for all employees in one place. I love how we are able to start a channel to talk about a specific project or chat to individual people. In my life of field i work in multiple different department from various different time zones but Slack unites all of us together. You are also able to integrate a lot of third party tools to help your conversations. I very much use the Gdoc integration and the conversation pinning functionality - I'd like to keep the more important up to date information on top of the chat thread.

You are also able to access Slack from majority of the devices, there is a nifty Desktop App, equally better mobile app and a web app all of them can be configured differently. For example, if you do not want a notification on your mobile but instead you want to follow the conversation on desktop - Boom, its possible and you can configure it all.

Cons

There are couple things Slack could improve. Firstly, Slack needs to allow their users to import table - if you are copy pasting an information from a table, Slack is not able to dissect that which is really a downer. The other being, connection issues, lately Slack has been having some connection issues whereby it is the only software in your system to not connect to the internet.

Team messaging done right

Pros

When working in teams of many sizes, Slack makes chat fun, efficient and non-obstrusive.

Slack is modelled on IRC, with users joining a "workspace" comprised of any number of themed channels. Users can set their notification preferences for each channel, which makes it possible to control the volume of notifications.
While some channels are meant to be used by everyone (#general, #random), it's very easy to create new channels for specific projects or discussions. I love the fact that all workspaces allow by default a "random" channel, encouraging non-work related discussion.

The flexibility afforded by this organization makes Slack a great fit for any kind of project sizes, but also other communities.

Finally, Slack supports powerful formatting (bold, italics, code snippets, quotes all using the intuitive Markdown syntax). Emoji and GIF support makes it even more fun. Emoji reactions are an expressive and fun way to respond to messages quickly, avoiding time wasted on picking phrasing (and spamming others with basic responses).

Cons

In settings where the free plan is not sufficient (e.g. large number of users), the "pro" options feel quite expensive.

While clients are extremely well designed on all platforms, handling multiple Slack Workspaces is still a bit of a hassle. Notifications arrive for all workspaces, but one needs to explicitly switch between workspaces to see messages. A unified view of all new messages across workspaces would be amazing.

The lack of a single account means that any preference set into one client (e.g. on desktop) will generally not carry over to another (e.g. mobile).

In terms of administration, I wish that we could set the default notification settings per channel, instead of requiring each user to go and tweak them manually.
