Slack is the absolute best communication tool
I love Slack! I've used Slack for 5+ years, I've also integrated it into numerous companies I worked with. To me, it's the absolute best work comms platform.
Pros
Huddles! It's so great to be able to hop on a quick call, with or without video, to chat about a task briefly. It's a game-changer for remote workers.
Cons
I like the canvas options but it can be confusing.

I am a professional developer who has used Slack for around 5 years
I enjoy how Slack is in a unique space of being the preferred messaging platform for software developers, both enthusiasts and professionals. It is modern & feature-rich enough to fit both personal and professional use. As mentioned earlier, the adoption on the professional side lags behind similar tools. I’ll finish by saying one of the most versatile features that Slack for Enterprise has built is the workflows/automation feature.. and it should continue expanding on this feature to outpace it’s competition.
Pros
The interface and integration capabilities of Slack are several times more modern than similar messaging tools.
Cons
Slack has more work to do to overtake market share in Enterprise use cases, meaning those professional teams who are already integrated into the Microsoft environment and prefer Teams. It is often the case where Slack is used on the side, as an addendum, to a team that is already using a different communication platform. I guess this kind of problem would be best remedied by better marketing & outreach to promote Slack’s features and ease.

Slack for building a community
My overall experience with Slack is good. It is the best tool in the market to build a community and manage projects within.
Pros
I like that I can create private channels for me and my C-executives team and control who access the channel. I like that I can access Slack in different ways like Web based, Software and mobile application which enable me to stay up to date with my Slack community anytime, anywhere. Integrating third party apps like Calendly with Slack is also very useful for me.
Cons
It is really confusing to find the people and conversations where I was tagged or mentioned on Slack. Sometime Slack sent me notification on email which I prefer, and many times it does not. Also, I don't like video calls in Slack, the quality if poor and the feature for sharing my screen is not very functional.

Fun tool to stay connected with your team.
Overall, I'm a big a fan of Slack. I really enjoy being able to customize it to my needs, and keep conversations separate in their respective channels. I also like that I can add a guest user at no additional cost; this is great when I just need to extend access to one channel to someone. The software is super user friendly and the ability to customize the layout colors and emojis make it super fun!
Pros
Slack is an awesome team tool! I have used Slack for years now and absolutely love it. It's easy to create channels for different topics and select who has access to each channel. You can build lists, save items for later (bookmarking them), view activity at a glance, direct message other teams members, and even customize and add fun emojis to the platform. Our team has so much fun with the emojis throughout the day! It's actually the best part of our day because it keeps the conversations fun and engaging.
Cons
I have yet to find a way to upload custom backgrounds for the huddle calls. The backgrounds that are available as default in the system don't do well during live calls. The image is poor and it's not a great user experience there.

Slack is the internal chat tool for any business
Great piece of software that does what it sets out to do very well. We've tried Teams, Hipchat, RocketChat and Slack is by far the best.
Pros
We are a prodominently remote business now and what stands out most about Slack is its ability to centralize communication in a way that makes teamwork seamless. The channels allow for organized discussions around specific topics, and the integration with other tools makes it easy to streamline workflows. It makes collaboration feel more dynamic because you can react to messages, share updates in real-time, and even automate some tasks to save time.
Cons
One of the things I like least about Slack is the potential for information overload. With so many channels, threads, and messages, it can sometimes feel overwhelming to keep up with everything, especially if you're part of a large team or working on multiple projects at once. Notifications can pile up quickly, and it’s easy to miss important messages buried in a sea of conversations.

Sleek team collaboration with Slack
Its a great communication tool that provides features for most users in companies of different sizes. It integrates well with a range of software to enable automation and search functionality.
Pros
The best features of Slack are the channels - public/private/shared, instant messaging and powerful search functionality
Cons
Risky security measures that make data loss a concern and the effort required for new learners to learn and adapt to the tool.

Great for Team Communication, But Room for Improvement
Slack has been useful for my team's asynchronous communication needs, but definitely lacks some of the functionality we need for maximum confidence in our communication.
Pros
I love that it has a free version and allows video, audio, text, and pictures for communicating with my colleagues. It's a good way for our remote team to stay connected.
Cons
I do not like the inconsistent notifications and the way threads work. My team has missed important communications way more often than we have with other similar apps.

Powerful tool for team communications
Powerful tool, well known and used by those inside and out of our organization.
Pros
Our company communications have been built on Slack - the ease of use and increasing features available have helped us grow and manage communications (both internally & externally).
Cons
The cost is somewhat steep, especially as the team grows. Was recently notified that they were adding a limit to 10 connected apps and would charge us 40% more if we had over 10 (this is down from the previous ulimited). Though they quicky changed their mind. Lead to a fair amount of wasted time internally assessing connections.

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.

It doesnt get better than Slack
I love it - it works so well for me and is a great way to communicate with my colleagues. I love all of the features and am constantly amazed with all the things it can do - automation is definitely a huge drawcard for me!
Pros
I love everything about slack. I have had to use other messaging services in the past and slack has everything you need and more - emojis, gifs, workflow automations, channels, groups. It is fabulous
Cons
Honestly - nothing big comes to mind. I love using Slack. I have noticed a bug recently were messages on my phone are quite delayed compared to my desktop app but this is very minor

PERFECT for collabing with large teams!
I have used Slack for almost 7 years to manage my team of over 100 contributors. We have group channels as well as team channels for certain teams (writing, editing, design, etc). It's perfect for group collab, one on one convos and group segmentation. I absolutely love it!
Pros
- Ability to have dedicated channels for certain topics
- Ability to have both public and private channels
- Option to create custom emojis (this is just fun)
- Easy to invite teammates
- Easy to @mention teammates and tag them when appropriate
- Excellent for team collaboration
- Supports video calls
Cons
Slack's free plan used to save messages for months now I believe after 90 days the old messages are deleted. This is annoying because we have group rules we have to repost often. That's the only downside.

Slack as an excellent work team manager
My overall experience with Slack was very good and I would recommend using it. Having had the chance to use both the free version and the paid version, I think that by making the small changes regarding the access to the history of old messages it would be the definitive platform for companies and team management. On the other hand, with full access through payment, you have full control of everything and no complaints at all.
Pros
For me, the best thing about Slack is the possibility of highlighting important messages, being able to make notifications such as wake-up calls and being able to gather important files for a work team within the same chat as a team. In addition to this, as an employee I appreciate the possibility of rotating between the status of “available, absent and unavailable” even while inside the platform.
Cons
The worst of Slack or rather its areas of improvement are in the limitations of the free experience, such as the search for files and messages that have limitations to be no more than 6 months old (I think there should not be limitations on the search for messages but perhaps keep it in the archives unless they are super important files marked by the team leader as indispensable).

It achieves a commitment to rapid response, ensures continuous communication between all team...
Slack contributed to achieving more effective communication and response always by ensuring that messages and data are delivered in real time.
Pros
Slack kept communication always available between all team members, gave managers the ability to continuously direct at all times. I liked how it documents the response, achieves transparency in accountability for shortcomings. I liked the ease of creating channels, defining permissions. It is great that Slack gives us the privacy needed to discuss and update data, and separates private communication for work from personal communication applications. Slack is easy to connect with all our applications, making transferring data and sharing everything simpler.
Cons
I did not think about the negatives, the positives are many and the benefits that Slack achieves are great.

This is an essential service when proceeding with the project.
When working on a project, it is very important how to collaborate with the participating members. Slack is very good as a service that we create together, such as quick conversation and data sharing.
Pros
Create projects, create channels, and easily invite members.
You can have real-time conversations with the invited members, such as 1:1 conversations and group conversations, and discussions and discussions on various topics within the channel. Also, within the same project, a separate channel for each task can be created and proceeded, so the project can be operated in various forms. And Slack is very light, providing a pleasant service environment.
Cons
I am using only the necessary functions of the slack, so there is no disadvantage yet.
