Slack Reviews & Product Details

Slack Overview
What is Slack?

Slack is the top choice for teams to communicate. It provides a virtual workspace that helps teams maintain open communication in a business environment. With Slack, users can host voice and video calls with up to 15 participants and even screen share with a desktop app, empowering better user interaction. Slack also supports options for private and group sessions, and one of its best features is Slack Huddles–an informal meeting space that lets you directly talk to your channel where you can share screen side by side with your team. The platform integrates well with Dropbox, Google Drive, and Trello as well.

"More than just a communication tool"
What do you like best about Slack?

All the integrations! Slack integrates with many of our data tools, making it an almost one-stop shop for alerts and messaging. Its search capability is comprehensive and makes find past messages easy to find. Additionally, Slack is easy and fun to use.

What do you dislike about Slack?

I wish you could customize a bit more in slack (the fact that command + k does not create a hyperlink is annoying). Additionally, I do not use the calls function as it is often buggy and less clear than Zoom. Notifications sometimes get lost (I wish they had an option to auto-remind you of DMs where you never responded)

What problems is Slack solving and how is that benefiting you?

I work in a completely remote workplace and Slack makes it easy for all of us to stay connected. Being able to find old messages is extremely helpful for documentation purposes. Since Slack is our predominant communication method, having all past conversations at the tips of your fingers is crucial.

"Slack makes work easier"
What do you like best about Slack?

The thing i enjoy the most is that i can get ahold of work collegues without their phone numbers, which i find less annoying. Phone numbers are more personal which i do not need.

What do you dislike about Slack?

I don't like that you can permanently turn off the notifications, this is more of a user feature, but our work is 24/7 and some people don't like to get the notifications

What problems is Slack solving and how is that benefiting you?

The problems slack is solving is that we are constantly able to communicate, which helps our work move along a lot quicker than if we were waiting for emails to come through

"A great tool for team communication"
What do you like best about Slack?

I like how Slack becomes a space to talk about certain topics in different channels, have direct communication with team members and establish processes

What do you dislike about Slack?

The fact that sometimes notifications can go unnoticed

What problems is Slack solving and how is that benefiting you?

Communication between teams can get really disorganized through emails and completely informal throught text message services such as whatsapp. Slack helps keep these conversation all in one place and section the conversations through channels, helping keep everything a bit more organized, formal, professional and within the schedule of everyone on the team

"If you want to build culture in a WFH world, this is it!"
What do you like best about Slack?

Slack is highly regarded for many good reasons. Its speed, lightweight, quick ability to make rooms, calls and ping people directly. However one that doesn't get sold is the amount of fun you can have on Slack and all the plugins that enable that. We have polls, gifs, video chats and it all makes WFH so much more bearable

What do you dislike about Slack?

Slack sometimes loves to disconnect me out in the mornings, not sure why but its a bit of an inconvenience.

What problems is Slack solving and how is that benefiting you?

As stated before, when working from home you lose any sort of human connection behind the screen. Through slack I have found it easy to connect to coworkers and befriend them.

"Slack Review"
What do you like best about Slack?

Quick intercompany connection, especially when working in a remote environment

What do you dislike about Slack?

It seems very buggy at times and the notifications sounds get a little redundant

What problems is Slack solving and how is that benefiting you?

I'm not sure, I've seen minor bug fixes, but overall is a nice interface for communicating with colleagues. I wouldn't say it more or less makes me more productive.

"Slack is the premiere team comms tool"
What do you like best about Slack?

Slack has a very intuitive approach to organizing and categorizing its information. There are plenty of 3rd party integrations and commands available and I can run multiple workspaces for multiple clients or jobs from the same window without having to switch products.

What do you dislike about Slack?

The channel lists could use some retooling to allow for better organization. I'd like more flexibility to create folders and move all channels wherever I wanted or even color code them for quick reference.

What problems is Slack solving and how is that benefiting you?

My team is completely remote, so an easy and intuitive way to communicate via IM or video or voice all in one is a game changer. I also like how multi-faceted the platform is in pulling data from other apps into a centralised database of searchable information.

"Great for internal discussions and short notifications"
What do you like best about Slack?

Everything on Slack feels professional, but with instant feedback like a chat room. The sharing of outside sources and links is particularly helpful with group products.

What do you dislike about Slack?

Slack notifications had a little learning curve at first, so I received the right amount of notifications for particular channels. It would be cool if Slack could batch process all notifications for specific time windows during the work day. I'm sure this already exists and I just haven't learned about it yet, they seem to make everything else as intuitive as possible.

What problems is Slack solving and how is that benefiting you?

Slack helps my coworkers and I communicate brief ideas and comments to each other and to work groups.
