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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The microphone's noise cancellation and static feature that record a human's voice are some of the most valuable features."
"We use the solution for document sharing, video conferencing, instant messaging, and file sharing."
"Slack helps me to read bulk messages."
"It offers customization options for various applications, including integrations with Zoom for video calls and a wide range of other integration plugins."
"The portal is at its best version now."
"I use Slack for communication with my colleagues."
"You can create channels between teams internally and externally, which is great. There is a lot of security with Slack internal, which is what I value."
"It's valuable for announcements and communicating between team members."
"Slack offers the ability to make customizable applications and plugins."
"Overall, it is a good idea as it works better than most solutions out there."
 

Cons

"There were some additional features coming up, as they informed us through email. But we didn't get any update on them."
"The audio calling service needs to improve its quality."
"I think Slack could add additional features without making the solution slower or more difficult to use."
"Slack tends to crash once a month."
"We’d like it to have more capability for everyone to work on one doc in real time all at once."
"Slack should add a feature to schedule meetings."
"The way groups are created on slack could be improved. Once you create a group of people, you can't add additional people unless you convert it to a channel."
"Slack could add additional and better integrations."
"It could be more stable than one of its competitors."
"It would be better if Slack had a 'select all' option to delete all the files."
 

Pricing and Cost Advice

"The license grants you a subscription and costs about $120. I am not aware of additional costs."
"Slack is not the cheapest solution, but that's okay."
"I would rate the tool's pricing a four out of ten."
"It is an affordable solution."
"The solution is expensive."
"Slack is definitely worth the money."
"It is less expensive than one of its competitors."
"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."
