Ended internal email overload in one day!
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.
PROSThe 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.
CONSSomeone 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.
Reason for choosing Slack
We barely tried alternatives as Slack was so highly reccomended, by the time we begun evaluating it , it was already sold. If there were other software used for 'Chat' they will all have been removed.

Slack is essentially advanced texting for business users
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.
PROSI 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.
CONSThe 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.
Reasons for switching to Slack
My client required us to use Slack.

Slack is the engine room of team interaction.
We use Slack extensively for communication purposes. Slack acts as a collaboration hub within my department, for extensive group discussions between members of my department. Infact , it is the fastest way to get responses to most work related queries from team members.
PROSI like that Slack retains our conversation history as a team . This is very important for future referencing purposes. Slack is available on a variety of platforms , and this makes seamless access to my team channels possible. This is important because team channels is where a lot of team discussions take place in real time.
CONSIt is common place to experience lags and stability issues during Slack calls. This is the only area where my use of Slack has been affected negatively.

Slack boosts collaboration and productivity.
Slack contributes hugely to improved team communication and collaboration.
PROSSlack channels is my most preferred feature on the Slack platform. They are easy to set up, customizable, and allow for important messages to be pinned. It also contributes to improved communication across the length and breadth of my company , ensuring we always stay informed with latest project and company news.
CONSAudio and video functionalities on Slack, tend to be unreliable. Especially , when one begins to compare the quality of audio and video call on Slack, with what is obtainable on traditional video meeting platforms.

Great way to stay connected with your team.
Really great tool, to keep communicated with your team when we all are working from different places in the world. Really robust system and also easy to use.
PROSI like the way you can have everything in one place: chat, calls, video conference, etc without the need of having any other software.
CONSI didn;t kie much the syncing with the mobile application, as if I read something on my computer, it will not get marked as read in my phone. So I had to open the conversations on my phone to to mark them as read.

A setup learning curve, but then pretty smooth
I have many larger organization groups that use Slack all the time... so much so that they assume EVERYBODY uses Slack all the time. And these groups consist of a large varied group of tech skill levels, so the software is pretty user-friendly, but takes a bit of hand-holding to get the app connected to the right workspaces on the right accounts.
PROSQuite easy to use and communicate with different groups once you have your workspaces configured and ready to go. Also, being able to jump from using my mobile phone app to using a desktop app is very handy (as long as both have been setup in advance).
CONSOccasionally I will need to be part of large-ish private channel who I don't know who the owner is or often the exact name. Figuring out who I need to contact to be allowed into the private channel can be difficult. Also, using different workspaces from different companies (or personal social groups) takes a bit of setup and not easily to transfer the same setup to different computers/platforms (if I want changes on my phone to mirror my home desktop to mirror my work desktop)

Messaging application used in professional setting
I liked this app very much but it had limitations. Also it somewhere fits the software space better that telecom for daily collaboration purposes.
PROSI liked the look and feel of the app. It was well designed and has many features when it comes to instant messaging. It is comparable to Skype for business before but just obviously better.
CONSIt does not have a calling feature. Also, it can be tough to get used to for people that are less tech savvy.

Love/hate relationship with Slack
I use Slack across 7-9 workspaces, one for each client/collaborator/workgroup. It's effective for keeping up with lot of people at once and the fact that I can mute certain workspaces/channels makes it manageable.
PROSSlack does a fine job of facilitating collaboration with co-workers, and does cut way down on the fragmented nature of workplace communications. The workspace -> channel structure does a good job of organizing communications, but messages and threads can become atomized very easily. Overall its the best tool I've used and is a vast improvement over the old ways. And the voice/video calling feature is perfectly integrated - can't wait for them to add transcription.
CONSI don't think this is Slack's fault, but the volume of stuff flowing through Slack is hard to wrangle. If you have more than a few workspaces open with a few channels each, it is incredibly easy to lose track of a message, thread, or link. and if you're using the free version you can find a critical message or link disappears behind the 10K message limit very quickly. Again, if you're getting good value from a product then you should pay for it, so no complaints about pricing, except that it's hard ot know what paying to: a workplace, or your own access to everything?

Basecamp had a product called Campfire which was integrated into Basecamp. It offered low-level messaging but Slack made it obsolete.

Great Business Continuity Tool
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.
PROS1:1 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.
CONSStill 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.
Reason for choosing Slack
Slack was inexpensive and has the value of simplifying the use across our different levels of technological expertise in the company.
Reasons for switching to Slack
To streamline processes across the globe and to ensure a means of consistency across all teams.

Slack is not Slacking for your Business
We believe Slack deserves a 9/10. There is more interaction on this platform than any other platform I am apart of! Wish they had fixed the group call features better! Maybe an investment in cloud?
PROSSlack gives users and business the ability to communicate on a platform that doesn't feel to formal like Microsoft teams and it great for the Gen Z/ Mellinial generation of workers. This is importanat because I believe flow of work is also correlated to work habbits. The user experience is flawless for chat and it also create the ability to easily make channels with persmissions like flipping light switch.
CONSI think one of the cringiest problems with slack is the inability of having a lightweight screenshare and the ability to not have dropped calls. There are many scenarios where we had clients or even our own team meetings struggling to have everyone on the call in sync. It has been a pain so we ended up using Zoom for group calls. We wish Slack didn't have this problem in the first place.
Reason for choosing Slack
Costs! Too expensive and no need to have Office 365 for every member of the organization.

The Gold Standard For Workplace Communication
We have employees all over the world so Slack is our hub for communication. We use it to have conversations, post announcements, and brainstorm ideas. It can also launch video conferences with excellent annotation features which makes it easy to share ideas about a document or piece of code.
PROSIt is extremely easy to use, there are many bots and tools to customize your workspace, and the actual communication tools are superior to the ones offered by Google and Microsoft. For example, the ability to thread conversations, easily set reminders about messages, and other subtle things add up to a much better communication system.
CONSI have experienced no major negatives as a user of the product. Depending on the number of users in your organization, the monthly cost will start to add up but I think this is similar to their competitors unless you're already paying them for other services that include something like Microsoft Teams, for example.
Reason for choosing Slack
Slack has better usability than Microsoft Teams and Google Meet. Users inside the company mostly preferred to use Slack even when multiple options were available. The threading functionality is particularly useful. Flowdock actually does conversation threading the best of all the products, but its a smaller player at this point so is probably not considered as often.
Reasons for switching to Slack
Flowdock was actually a high quality product and the best competitor to Slack that I've tried, but Slack became much more popular and started to have better integrations with other third party services. At this point, Slack has become synonymous with workplace communication software in the same way that Zoom has for workplace video chat.

Slack is a mainstay for my inter-connected teams and communities!
Slack is hands down my favorite way to keep productive up, communication lines between teams clear and more concise, and as a way of messaging back and forth in a pretty straight-forward, not super distracting way.
CONSThere is not really a complaint I can think of in regards to Slack. I have never had a real issue with it in my 8+ years of using the application.
Reasons for switching to Slack
Microsoft's product did not even compare to the ease-of-use and clarity, brevity of implementation and start-up.... Slack is just way easier to use and more people I have worked with and currently with work still enjoy it/rely on it for day-to-day communication and project update needs. ESPECIALLY in a newly, mostly remote work environment!

Best app for messaging!
Slack is very fun to use and easy to get used to. I think every company should use it. It’s also very private so only people within the company have access to message you. External users cannot find you or message you. Great software overall!
PROSThis app is very easy to get used to and it’s very customizable. You can choose a color theme or create your own and manage which channels you want muted or you got want to receive notifications. I also love that they have an mobile app, a desktop app or you can use the web browser to login. It’s a great way to communicate with colleagues 1:1 or by group chats (channels). You can also generate polls or gifs in the chat bar, respond to messages in a thread to not overflow the chat with responses and react to messages with emojis. I love it. I’ve used it for years!
CONSEvery so often the software does have issues. It’s happened maybe once or twice a year where it crashes for a couple of hours and messages cannot be sent. I think it has to do with the server or something but it usually resolves pretty quickly.
Reasons for switching to Slack
Jabber was reliable but very outdated. Felt like I was stuck in the 90’s chatting on AOL or messenger. It doesn’t have half the functionality that Slack has.

Nice messaging platform
Overall slack is a nice messaging platform and really helps the individuals while working in a project of multiple team members. It helps in sharing of text messages and files and also has calling features and major third party integrations which makes it a complete package.
PROSI found slack a powerful tool to communicate with the other team members in real time. It has better voice quality on call, large size file sharing, one-to-one and group messaging. It also allows to star the messages, which is really helpful to bookmark the important information from the chat. The features such as wrapping the text in code snippet and selecting the file type (for example, html, java, js, etc.) is beneficial for developers. It provides APIs to create custom applications and also has an app directory from where users can install out-of-the-box integrations for Github, google drive and other third parties.
CONSThere are few features which are missing, for example, whenever a user is removed from the workspace, no notification is being sent back to the user. Also, the slackbot could be improved, most of the times, it just provides the search results from the slack help directory. It is not easy to switch workspaces. One has to close the workspace completely and then switch back to the another workspace.
