View all your unread messages

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

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


Set your All unread view

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Click Sidebar.
  4. Tick or untick the box next to Show all unread.

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


Navigate unread messages

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

Sort unread channels

Decide how to prioritise your unread messages by changing how they’re sorted. You can sort messages alphabetically, by newest activity or by oldest activity. On paid subscriptions, 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 unread view and click Mark all messages as read.

  • If you click Mark as read too quickly, just click Undo to keep those messages in your All unread 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 unread view, the  syncing arrows icon will appear in the header. Click on the icon to reveal a fresh batch of unread messages.

Message shortcuts

You can't post new messages from the All unread 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 to catch up with what’s new even more quickly from the All unread view.
