"Ended internal email overload in one day!"

Comments: Making progress on internal discussions can start in seconds with a Slack group chat. It is hard to imagine a way of managing teams in different countries any other way. Slack removed a reliance on internal emails which often fell short where key people weren't copied in or involved in the discussion. In a similar way, it avoids the CC happy emails where some team members may not need to be included and is an unnecessary distraction. With public channels, anyone can decide if they continue to remain invovled or just choose to 'mute' a channel, even just for a period of time. After using it for over 2 years now, the results are that people in our organisation can manage their communication and let it fit in their workflow. With various integrations it can also be a real timesaver when on the move.

Pros: The options of private/direct group conversations and public and private channels make the various types of cross-team communication most companies need so simple that it's hard to remember how we got anywhere when relying on email. As a personal favourite feature, the option to upload custom emojis makes messaging easier, not just for fun but in the cases where logos/symbols can be easily understood by everyone, it makes quick shorthand.

Cons: Someone who reccomended this product did warn to be careful that it may take over our lives, and they weren't wrong! Through no fault of Slack , the ease of adding channels, setting up groups etc does admittedly add to the noise that can sometimes be a distraction. The Slack call quality can sometimes be unreliable and audio quality isn't amazing.

"Great Business Continuity Tool"

Comments: It has been a great experience using Slack. It is a valuable tool and I really like how we are able to collaborate as a team and make it seem as if we are still working together in the office.

Pros: 1:1 Chat - Ability to have 1:1 conversations with team members. Useful when working on a project together.
Team Collaboration - Ability to bring a project together and share with a team.
Group Chat - Ability to have one area/space where the team collaborates, shares ideas, and works together to communicate issues.
Bot Integration - Ability to integrate various tools and bots that can make the day easier. Ability to integrate to web conferencing tools like Zoom, Webex, Teams. Ability to create to-do lists, track time, etc.
Manage Team - Great way to manage a team who is working remotely in various geographic locations.

Cons: Still trying to work around our SSO integration - This is mostly an internal bug we are trying to work on, but it would be nice if we can make Slack to work for a single sign on experience.

"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.

"Best Team Communication Software Out There"

Comments: Very positive. Few complaints. A super fun, dynamic, effective platform for work, projects, etc. alike.

Pros: I don't think anything can compete with Slack. It's quick, efficient, fun to use, social, playful (GIF's! /giphy), unclogged and dynamic. The calling and group chat features have been especially handy lately with remote working. I also love that you can add such a diverse range of content (code, movies, images, gifs, lists, quizzes, link previews, etc.). The polls + GIF randomizers also keeps things 'fun' and light, useful for all types of people in all types of roles. The UX is very straightforward, the interface design is beautiful and FUN, which is important for a communication platform. People enjoy being on Slack. I don't mind opening it up - and that means a lot, considering it means I'm working. The search and archive functions are also great.

Cons: Don't have many complaints, honestly. I think it might be better if you had a way of storing 'updates' for projects, the way Basecamp does. Pinning messages, or files? To prioritize them, so they don't get lost in the conversation flow. Also could maybe benefit from a 'presentation mode' for Slack video, unless it exists already, to compete more with its competitors like Zoom? But overall, I have few/no complaints.

"An industry leader for a reason"

Comments: I love slack and it is always getting better. Finding my chats, creating channels, and adding integrations are easy. I can’t recommend it for business enough. It’s so fun that I am trying to find other uses for it just so I have an excuse to use it.

Pros: Slack has become the industry leader in workplace communication and for good reason. It makes for a flexible place to have contextual conversations and integrates Into your workflow by easily allowing tools to integrate Into the application. From shopping carts to service monitoring alerts to team polls, there are integrations for just about everything. These integrations also allow meaningful, yet simplified, interactions so I don’t always have to leave The context of my conversations.

Cons: The largest problem is cost as well as limits in how I can leverage Slack For both work and for non-work related communication. It wasn’t built for non-work communication so I can’t truly complain. But I would love to see some focused paradigms show up in the ecosystem to make it so I don’t have so many chat applications. One other issue is the confusing of finding and managing my custom web hooks. As often as I use it I always end up spending 5 minutes on the site trying to figure out what we hook integrations I have and where to reconfigure them.
