Pros:

The giphy integration is the perfect way to get folks engaged. I love the search function and the auto-response feature the best.

Cons:

I get lost on some of the channels - there are a lot of channels with different teams. I find that I get confused with which channel is for what.

Game Changer without much change

4.0 2 weeks ago New

Comments: I have mixed feelings about the platform. I appreciate the ability to create multiple groups, which helps organize communication effectively. Additionally, I find the huddle feature particularly useful; its informal nature allows for quick, one to one interactions that can resolve issues more efficiently than text messages. Often, textual communication can lead to misunderstandings due to lack of context or misconstrued tone, but initiating a brief huddle can swiftly address these problems.

Pros:

That it can be integrated with a number of softwares.

Cons:

Not doing a video tutorial when a new feature comes out.

Slack is okay but nothing special

3.0 2 months ago

Comments: It's very similar to sending an email because there is no interactive engagement. So for that reason, there are other platforms I prefer (like Teams).

Pros:

Slack is easy to setup and you can join a variety of group chats.

Cons:

It is not possible to see if your message has been ready or if someone is typing or responding.

Slack for building a community

3.0 3 months ago

Comments: 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.

Slack Review- 2025

5.0 2 months ago

Comments: Started using Slack about 8 years ago and i'll never go back. If you are part of a remote team and want an employee engagement platform to help with company communication, Slack is your best bet!

Pros:

Incredibly easy to communicate across multiple channels and departments. Easy to create sub groups for project management efficiency.

Cons:

The free version has a ton of limitation and almost requires you to pay for the upgraded version.

A good messaging app, except for the language barrier and messages older than 90 days

4.0 2 months ago

Comments: It is a good application for messaging, but I think it is not sufficient for general use and general evaluation.

Pros:

A nice application with a simple user interface and the ability to create multiple channels and assign people to channels.

Cons:

The workspace is displayed to all users in the language it was created in. For example, I have to use German Slack for a project we are working on together with the Germans, but I have to use English Slack for the workspace I created for my own team. Instead, it should be opened in the language of each user. It is also very illogical to ask for a subscription to be able to see messages older than 90 days. Why is there a free version if I can't see my conversations older than 90 days?

Great tool that allows us to practice what we preach when working with our clients

4.0 5 months ago

Comments: 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.

Our remote team loves slack!

5.0 4 months ago

Comments: My remote team loves slack! So much easier to use than Gmail's chat feature! We love that it is easy to use on our phones, too!

Pros:

I love that I can easily communicate with my remote team, schedule impromptu video calls, and integrate apps! I also branded our slack channel to our company's brand!

Cons:

Slack will notify you with notes about your apps, tags, etc. It can get confusing if you get a lot of notifications (ex. a note that your google drive file might not be accessible to everyone in the channel). You have to close out the notification to remove it from your channel feed. It's only visible to you, but still annoying!

PERFECT for collabing with large teams!

5.0 4 months ago

Comments: 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.

What I Contemplate ‘bout Slack

5.0 3 months ago

Comments: Sending large files online, team collaboration via unlimited communication channels and video conferencing.

Pros:

Slack for nearly three years has been a remarkable tool for sending and receiving DMs. Mobile application on my iOS works perfectly lit that I do not have to shift to cloud apps.

Cons:

Thanks to the vendor for ensuring zero issues on Slack for over two years that I have been using this tool.

Great for communication, worked better when I delegated it for just the team

5.0 2 months ago New

Comments: Easy to use, flexible for our small (8-10) team, and eminently adaptable for those who wanted to stay in touch with others. For me, I found I enjoyed not being on-call and gave the space over to the team

Pros:

It enabled my team to communicate quickly on details, maintain a sense of togetherness, and even allowed for random brainstorming.

Cons:

I am not comfortable with the idea that I could get interrupted at any time. What began as "my focus times" in two 2-hour windows became an all-day thing when I realized my team worked well or even better without me

No longer worth it

2.0 3 months ago

Comments: Good for a while but the product only really got worse with time. The massive price increase meant we could no longer trust them with our money or data so we left and we don't regret it at all.

Pros:

A lot of products integrate easily with Slack. As a replacement for Skype it was quite good.

Cons:

Rug-pull price increase forced us to migrate. We found Zulip which ended up being better in practically every way.

Slack as an excellent work team manager

5.0 4 months ago

Comments: 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).

Slack for the everyday user

5.0 5 months ago

Comments: Slack is wonderful—it’s never a question of its usefulness. It gives our team the opportunity to grow, connect, and collaborate effortlessly. Slack is easy to train on and lets you show off your personality. It also has many hacks and tricks that most people don’t know about, like setting reminders, sharing a GIF instantly, and mentioning individuals, only those online, or an entire channel. It’s a smart system that I love using.

Pros:

The ease of communication between teams, colleagues, and even adding a second or third company is so easy. I also love how easy it is to start a 'video call' huddle with anyone in your organization. With one click, you’re chatting over video, sharing your screen, and connecting with someone on the other side of the world. It also integrates very well with Zapier, Google, Asana, Calendly and many more.

Cons:

I'm not sure if this is a Slack issue or a user issue. I’m an Apple product fanatic; however, when my Slack is buzzing with notifications from all the workflows and channels I’m in, my phone, laptop, and watch all go off simultaneously, which can be overstimulating. Although I’ve turned off notifications on my watch (for my sanity), there are times I wish only certain channels would communicate to it.

Perfect for team collaboration - internal and external.

5.0 4 months ago

Comments: I've used Slack with several organizations, including a non-profit and marketing agencies. We used it to do internal planning and also planning with the client in a channel dedicated to them.

Pros:

Slack is great for working with internal teams and with external guests. I like that you can create lots of channels for specific topics or teams and that you can reply to comments in an individual comment replay thread.

Cons:

I can't think of any Cons. Slack's functionality is great and works very well.

A fundamental tool for collaboration within the workplace

5.0 6 months ago

Comments: Slack is the main tool in my role. In a fully remote position, the entire workday happens on slack, which is a reliable tool to manage conversation within a team, and across different teams. The integration with external tools (eg Knowledge Management tool) that allows to surface them within the Slack interface facilitates conversations since it allows to stay within the tool.

Pros:

- Integration with other tools - Conversation management (threading, scheduling) - emoji customization to match company culture

Cons:

- difficult to manage multiple threads without popping them out

All-in-One Communication Tool

5.0 3 weeks ago New

Comments: Overall it's been great, our team has been able to use it to the fullest, from keeping up with projects, tracking progress, sharing project links, having it as our main platform for meetings and huddles, and even being able to communicate directly with clients who also used Slack, it's been a great experience overall.

Pros:

It's the go-to communication app in our company, and with good reason. We love being able to have different ways to set up communication, from private messages to being able to create channels, it has been a great tool in keeping our workflow organized. It even supports project management needs with the possibility of using the Canvas to store key information about specific projects. Having the ability to add third-party bots also boosted our workflow, from managing PTO to having random questions in our "fun" channel to create rapport. And I personally love the customizable emojis and giphy integrations to make conversations more engaging and personalized.

Cons:

As part of a multicultural team, one minor struggle was that sometimes the voice note transcriptions were inaccurate. It would have been nice that the auto transcription could detect the language of the voice note and adjust accordingly.
