Intuitive communication

4.0 4 weeks ago New

Comments: I have been using Slack for years and it's great to see product improvements over the years. It's an easy tool to setup for remote teams to get communication going in a more structured way than email. My preferred tool over MS teams.

Pros:

It's an intuitive workplace communication app that has a lot of layers of further functionality past DMs and channel communication. You can create to do lists, build automations for reminders and Slack integrates with almost every other tool you use.

Cons:

The use of threads isn't always straightforward for everyone. There is a company culture/transformation piece to using Slack effectively or to it's max potential which can be difficult to get everyone onboard. Notifications can be cluttered.

Great corporate communication tool!

3.0 last week New

Comments: I would recommend it for companies who are more corporatized to mainstream their communication, reports, and updates to team members large and small scale.

Pros:

It is easy for company-wide communication or smaller team communication.

Cons:

I did not like that some of the channels were not "opt-out"friendly. I'm not entirely sure if it was the companies corporate channels that made it hard for some of us employees to cancel out of or if it was Slack's ease of "opting" out, but that was the only true frustration I had with the technology.

Fun tool to stay connected with your team.

5.0 2 months ago

Comments: 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.

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 the internal chat tool for any business

4.0 3 months ago

Comments: 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.

Great for Team Communication, But Room for Improvement

4.0 3 months ago

Comments: 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.

Slack Knack for Greatest of all Time Messenger

4.0 last month New

Comments: After using Slack for more than two years, I felt very optimistic that Slack is the most valuable tool for communication, which makes a great replacement for Microsoft Team in the case of smaller teams or smaller companies. From using Discord for my personal uses to using Slack for work, I can really say that Slack works very well in plenty of situations for those who are into messaging.

Pros:

Slack has features that allow users to utilize a lot for their work or for other purposes. Highly versatile.

Cons:

While Slack is easily thought to be a hard-to-be-replaced tool, I'm hoping there are some improvements, including canvas, lists and developer mode. With these features considered, Slack will be spot-on. I would have expect the creator or developer to implement more features for other criterion other than just messaging.

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 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 5 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.

Cool way to work and chat.

5.0 5 months ago

Comments: My experience with Slack has been really positive. It’s incredibly user-friendly, with all the tools for both quick, casual chats and more structured team collaboration. I love how easy it is to send files like spreadsheets and data right in the chat, so we don’t have to jump between different platforms. The fun features, like GIFs, stickers, and video clips, add a nice touch of personality, making remote work feel more connected and personal.

Pros:

I love how Slack makes our virtual office feel more alive! It's easy to use, and I’m all about the fun features like stickers and videos that let me add some personality. Plus, I can send all kinds of work stuff—like sheets and data—which is super useful. It definitely makes work chats feel more efficient and way more enjoyable!

Cons:

I honestly can’t think of anything I dislike about Slack.

Slack is great!

5.0 last month New

Comments: I have enjoyed my experience with Slack. It makes it really easy to communicate with my team and separate different things into different channels for those who should be concerned about different issues. It is very easy to use as well.

Pros:

I like how different channels can be created for individual groups of people. I also like the search functionalities and that I can search for keywords and find messages from years back about the issue. I also love the bookmarking function.

Cons:

I wish that the notification settings were easier to configure.

Can't imagine my workday without Slack

5.0 2 months ago New

Comments: I was a Microsoft Teams user from 2017 - 2022, and I found it to be usable and an important tool. But that's a night and day difference to Slack's use in my life. I find the interface to be clean and easily usable. I work at a remote agency, and Slack is so integral to staying in communication across projects. We have channels for each of our clients, and these channels are such a great place to keep things organized. The huddle feature makes it so easy to have a quick call with each other. I also love the statuses - being able to see when people are in lunch, in meetings, or - as we use Slack, what their Spotify Daylist title is - is such a great way to do things. I love being a Slack user - I can't imagine my workday without it.

Pros:

I love that in a remote work culture, Slack makes it easy to get to know and appreciate co-workers. I love how easy it is to track different projects, keep up conversations with coworkers, share inside jokes, and be a hub for company experience.

Cons:

Perhaps the only thing I dislike about Slack is how easily available it is to me (no work life boundaries when you can always check it!) and every once in a while, an integration acts a little funky with it. For instance, I have my Google calendar synced up with it, but it will sometimes show me the notification awkwardly. Those two things are things I have to dig deep to find as a frustration.

Slack is a must have for your development team

5.0 5 months ago

Comments: My favorite instant messaging tool for the workplace, especially since I am on a development team. The integrations also create a single place to get updates on all of the work going on.

Pros:

Easy to use, lots of plug ins and integrations. Developers love this app and it allows you to create channels as well as small adhoc groups to keep people up to date and have quick conversations. Huddles are also very convenient for a quick oral conversation. We have integrated it with Atlassian to keep people up to date on tickets and changes in status. We also have channels with external partners to make communication with them even easier.

Cons:

Sometime the number of channels and direct messages you have available at any time can be overwhelming. You can remove yourself from channels and delete direct messages but often there are a lot that you want to keep up with.
