    Absolute business communication software

    Updated: Nov 01 2020
    Summary

    Overall, it gives the ability on our screen to centralize all of the business communication on one page. The plugin support (Zoom, Zendesk, and others) makes lots of things easier for us.

    Positive

    We are using Slack for both aspects of communication (inbound and outbound communication). It's an ideal tool for business communication. It makes every conversation professional and streamlined at one page. The plugin support of external tools is fantastic. The interface is clean and visually attractive.

    Negative

    The special command feature (hashtag) can't give the search result what I want.

    Great communication tool

    Date: May 28 2020
    Summary

    At this point in time, we wouldn't look at changing the app to any of its competitors. But with time, who knows. The main reason for keeping it is the integration module with JIRA and Dropbox. If you have a big enough organization and can pay for it this is probably the best collaboration app out there.

    Positive

    Ability to add extensions like JIRA, Dropbox.
    Ability to create different rooms for different teams for more streamlined communication.
    Conference call is another nifty feature that our team uses extensively.

    Negative

    It's expensive than Discord which kind of does everything that Slack does.
    The free version has a lot of limitations like the deletion of history. So, if there is a message sent a long time ago, it's gone. FOREVER.

    Overall a great way to communicate.

    Positive

    Cross platform and accessible from app/web on most devices.
    Can create channels and multiple workspaces for different purposes.

    Negative

    Higher number of channels and workspaces make it harder to manage.
    The usability of storage and size is based on subscription.

    Great Platform for Team Communication

    Date: Apr 02 2019
    Summary

    It's an amazing product for team communication. It solves communication gap between the team and enhances the team coordinations.

    Positive

    Slack is very easy to use and any one can use it without any special training. The best part is that it allows to create multiple teams and you can also communicate with one-time account setup.

    Negative

    I have found only single issue regarding the desktop notification. Some people in our company have reported of a blank screen on startup, but that was due to graphics driver and it is a quick fix. Overall it's a very amazing product for team communication.
