Organized communication with categorized channels and content sharing
Pros and Cons
  • "Slack's categorization of content and the availability of channels are highly valuable, as they keep communications organized."
  • "Slack's Canvas feature could be improved in terms of its user experience."

What is our primary use case?

We mainly use Slack as a communication channel. Additionally, we use it for remote working and voice meetings through Slack Connect.

How has it helped my organization?

Using Slack has significantly improved our internal communications, helping avoid personal and work communications being mixed. With Slack, we have categorized channels that help in maintaining clarity in communication.

What is most valuable?

Slack's categorization of content and the availability of channels are highly valuable, as they keep communications organized. 

We also use Slack's features for brief ideation, sharing content onto Notion for comprehensive documentation. We are really satisfied with Slack, having used it since my first company for about five years.

What needs improvement?

Slack's Canvas feature could be improved in terms of its user experience. While they are trying to integrate something like Notion, it doesn't work well, which is why we still use Notion for official documentation.

For how long have I used the solution?

I have been using Slack for about five years.

What do I think about the stability of the solution?

Slack has been very reliable, with server issues occurring only once or twice a year.

How are customer service and support?

We have never contacted Slack support since we haven't had any issues.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

Before using Slack professionally, we used platforms like KakaoTalk, which mixed work and personal communications and lacked a clear system for organizing conversations.

How was the initial setup?

The setup was straightforward as we simply use Slack as a communication channel.

What's my experience with pricing, setup cost, and licensing?

The pricing is reasonable. While cheaper would be better, we are generally satisfied with the current pricing model.

Which other solutions did I evaluate?

Discord is more customizable than Slack but is also more complicated and suited more for casual or club environments rather than professional company use.

What other advice do I have?

If your organization needs a fixed number of participants and an organized communication structure, Slack should be adopted instead of a messaging app. People who have used competitors like Microsoft Teams often prefer Slack. 

I rate Slack ten out of ten, as I've never considered replacing it.
