Collaborate effectively in channels

Communication at work happens in different places, like emails, chats, and calls. This can result in silos that make it difficult to work effectively and share information.

In this tutorial, you’ll learn how to use Slack to:

  • Work in channels
  • Share files and clips
  • Communicate clearly


Work in channels

In Slack, communication with your team about specific topics takes place in channels. When you work in channels, use mentions to get the attention of the right people, and emoji reactions to simplify communication.

Mention a teammate

Add an emoji reaction

If you have a question for a specific teammate, you can mention them in a channel to get their attention. They'll receive a notification and the rest of the team can follow along for context. a mention included in a message in a Slack conversation

Share files and clips

You can add files to any conversation and record audio and video clips to collaborate with your teammates more easily.
