Heads up: Some of the features we talk about here require a paid plan. If you'd like, read about limitations on the free version of Slack or consider upgrading your workspace.


From the sidebar, you can access the channels you've joined, open your direct messages, view activity that might need your attention, and see a list of your saved items and reminders.

2. DMs

3. Activity

4. Later

  Home is where you'll access your conversations, including channels. Choose the conversations you're part of by joining and leaving channels, and keep them organized with custom sections. Organizing conversations in the Slack sidebar into customized sections
  DMs is a list of all your direct messages (DMs) that you can search and filter. Use DMs for one-off conversations that don't require an entire channel of people to weigh in, or as a way to start a   huddle with a coworker when it’s easier to talk than type.
  Activity is a single view of everything that might need your attention. See messages you’ve been mentioned in, threads you’re part of, and reactions to messages you’ve sent.
  Later is where you’ll find messages and files you’ve saved for later and reminders you’ve set. Prioritize tasks and enjoy the satisfaction of marking items as complete.

Tip: Tailor what you see in your sidebar by adjusting your preferences whenever you need.


Channels are fundamental to working in Slack — they bring the right people and information together in one place, and make it possible to organize work around a common purpose.

Click the channel name to see details about the channel you’re in, like the channel topic and description, and files shared in the channel. You can also open the   canvas and start a group   huddle to meet with your teammates over a voice or video call.
Channels provide a dedicated space to write messages and add files. With everything related to a particular topic, project, or team in channels, you can scroll up or jump to a date to see the conversation history any time you visit a channel. Navigating to the very beginning of a Slack conversation
Emoji reactions are a quick way to respond to any message in Slack. They're both fun and helpful for getting work done — a simple reaction can often replace the need for a follow-up message.
