It has different messaging channels. Public channels allow team members to communicate without the use of email or group SMS (texting). Everyone in the workspace can use public channels.


Private conversations between smaller sub-groups go on in private channels. These private channels can also be used to organize large teams.


The direct message feature allows users to send private messages to specific users rather than a group of people. Direct messages can include up to nine people. You can use Slack to turn a direct message group into a private channel.


What sets the Slack paid plan apart from the free plan is that with the later one can search more than 10,000 archived messages and add unlimited apps and integrations.


Slack works with many third-party services and also supports community-built integrations. Some major ones are Google Drive, Trello, Dropbox, Box, Heroku, IBM Bluemix, Crashlytics, GitHub, Runscope, Zendesk, and Zapier. The free plan allows the addition of only 10 such services


It also provides an application programming interface (API) for users to create applications and automate processes. This allows the following:

  • sending automatic notifications based on human input
  • sending alerts on specified conditions
  • automatically creating internal support tickets.
