View all your unread messages

Browsing all of your unread messages from the desktop app lets you catch up on the messages you missed when you were away from Slack. While you're at it, you can act on those messages too:

Note: For now, the All unreads view is only available from Slack on your desktop.


Set your All unreads view

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Click Sidebar.
  4. Check or uncheck the box next to Show All unreads.

Note: Messages in muted or archived channels aren't included in the All unreads view.


Navigate unread messages

From All unreads, manage how you'd like to view unread messages to help you prioritize work in Slack.

Sort unread channels

Decide how to prioritize your unread messages by changing how they’re sorted. You can sort messages alphabetically, by newest activity, or by oldest activity. On paid plans, you can also sort scientifically — a view tailored to how you use Slack.

Mark messages as read

Click Mark as Read to clear a channel's messages when you've finished reading them. You can also scroll to the bottom of the All unreads view and click Mark All Messages Read.

  • If you clicked Mark as Read too quickly, just click Undo to keep those messages in your All unreads view. 
  • Save a channel's messages for later by clicking the  arrow icon beside the channel name to collapse it. Click the arrow again when you're ready to read the unread messages.

Refresh for new messages

When new messages become available while in the All unreads view, the  syncing arrows icon will appear in the header. Click the icon to reveal a fresh batch of unread messages.

Message shortcuts

You can't post new messages from the All unreads view, but you can save, share, add a reactionpinset a reminder, or start a thread.

Jump to a channel

To post a message in a channel, or jump to a conversation, click the time stamp on any message to visit that channel.

Keyboard shortcuts

These shortcuts will help you get caught up even faster from the All unreads view.
