A collaborative tool with a good noise cancellation feature
We use it to conduct meetings because it is private.  The microphone's noise cancellation and static feature that record a human's voice are some of the most valuable features. The application also provides notices to everyone at the same time. You can easily use it on your phone, so it's a very…

A competitive solution that improves collaboration and productivity
Slack has been around for a long time, and it's an industry leader. Of course, Salesforce owns Slack now and is starting to integrate into it. I have attended Slack conferences and met with product and support managers. They're an excellent organization. Choosing Slack depends on the organization's size, so you need to plan your deployment and make sure you put some controls and standards in place and not just turn it on. If you're a Slack shop, you will have to have something like a Zoom or Microsoft Teams platform for when you need to do video conferencing internally or externally. Many shops have both products, but they use Slack for collaboration, chat, and so on, and use Teams for video and audio conferences. At the end of the day, Slack is missing those capabilities, so either you're going to be a Slack/Zoom shop or you're going to be a Microsoft Teams shop. I rate Slack an eight out of ten.

More Slack pros
 

Cons

"The audio calling service needs to improve its quality."
"There were some additional features coming up, as they informed us through email. But we didn't get any update on them."
"It would be better if Slack had a 'select all' option to delete all the files."
"The tool is a bit slow."
"Slack's screen sharing might also add the remote control feature, which is not there."
"I have found it cumbersome to create and set up groups, or channels."
"The solution should have less frequent updates."
"I would like to see a special feature for multiple people to collaborate on a document, working on it at the same time."

Pricing and Cost Advice

"The license grants you a subscription and costs about $120. I am not aware of additional costs."
"The tool's pricing could be cheaper."
"The solution’s pricing is cheap."
"The pricing can range up to about twenty bucks a user. You can spend a lot of money, especially if you're talking about thousands of users. Generally speaking, Slack is less expensive than Teams. Slack doesn't include all the bells and whistles that Teams does. So you can go from a $6 license in Microsoft 365 to a $50 license per user per month, and there's a lot more you can do in the $50 license."
"It's on the more expensive side."
"The solution is cheap in my country."
"It is less expensive than one of its competitors."
"It is an affordable solution."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."

Overview

The nature of work is ever changing. Right now, it’s more fast-paced, less predictable. Avaya Spaces is how to handle your usual tasks, but also the unplanned and new-priority work that arrives nearly every day. Work from anywhere and still show up.

Slack is where work happens. It’s a digital workspace that powers your organization — all the pieces and the people — so you can get things done.

Slack brings all your communication together in one place. It's real-time messaging, archiving and search for modern teams.
