"A great team communication tool"

Comments: 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.

"Slack is the solution for internal communication and collaboration"

Comments: Slack helps our team stay coordinated, interact in a timely manner, and track information in channels that provide context.

Pros: Slack's ease of use and understanding it paramount. While I find Teams to be over-extending itself into the Office world, Slack is just about making sure you can keep communication clear, timely and open. The ability to shift between private DMs, open channels, and private channels nicely delineates the way you can manage communication across a team. We use Slack for all internal communication, relegating email to external comms, which works really well.

Cons: The channels can overwhelm casual users at times. While the system tries to clean things up with suggestions, I think Slack should do more intentional hiding of under-used channels to keep it clean.

"THE digital tool for team communication"

Pros: I think that, these days, Slack is among the most popular picks for teams that would like to work remotely, for instance. So, through Slack, teams get a sort of a centralized digital hub where they can gather and exchange value and info. I'm a fan of the ability, that nowadays, Slack gives to its users, of being able to host call straight from Slack. No worries about third-party platforms working with Slack, you can use the platform's own technology to communicate with the members of your team, video calls included. Plus, the smartphone app enables you to work, access your Slack channels and interact with people from anywhere. And lastly, I'm a big fan of the Apps integrations that can be used with Slack. Would you like for your Slack channel to do something you can't do right now? There's probably a Slack app for that. Are you looking for a better way to use Slack in combination with a project management tool you use? It's doable, and so is providing customer support by connecting your customer service tool to Slack.

Cons: I'm probably not the first to say this but, when it comes to Slack notifications, there must be a better way to control them. Think about having a very engaged Slack space with several channels... and each channel received and keeps receiving a notification after the other. It can be disruptive and distracting, and I think it's something that Slack should address and change as soon as they can so that users don't get "bombarded" by a ton of notifications.

"Slack is essentially advanced texting for business users"

Comments: I started using Slack because my client required it. I find that it cuts down on my email dependence but I'm often frustrated when attempting to compose a message without standard elements such as tables, inline images, etcetrera.

Pros: I like the ability to stay in touch with our users via whatever device I'm currently using. For example, I can respond from my home computer, tablet, work computer or via my phone. I especially like the ability to be notified of a new message via my phone where I can read the message on the phone but can step over to my laptop to reply. I also appreciate the ability to add an email thread to a Slack Channel by simply adding a slack email address (each channel has a unique email address) to the CC field when I reply.

Cons: The biggest con for me is the extremely limited amount of formatting available to Slack messages. I can make a font bold and add links to files/images but I really miss the rich text features many similar apps provide. It's also frustrating to need to keep typing adding the user name(s) when I'm responding to a message. I'm assuming that this is by design but it would really be nice to be able to "Reply All" to a conversation thread. The desktop Slack application (running on Windows 10 Pro) has a "clunky" feel to it. It's written with a framework that allows the Slack developers to write HTML and JavaScript code that is essentially compiled into a Windows application and it definitely shows. Something as simple as selecting text is counter-intuitive (until you realize that it's essentially a web page mascaraing as a Windows application.

"Mostly perfect"

Comments: Slack has been fantastic for keeping our remote workforce connected, fostering a sense of community within our organization, and freeing up our inbox for more important items. There have been a few quirks over the years, but the UI changes have been mostly positive. It seems like the platform is constantly improving with features that are actually useful instead of features for the sake of adding new features.

Pros: Slack Connect is great for facilitating efficient communication with partner businesses, vendors, and clients. Slack was already a vital part of our business and the ability to connect with other organizations on Slack cuts down on email significantly.

Cons: My only complaint with Slack at the moment is that Slack Connect conversations are placed at the top of the conversation list, even above starred conversations. Internal communication is more important to me and not having an option to place conversations with outside organizations below the ones I've determined are most important is an annoyance.
