View all your unread messages

Browsing the All unread view on desktop 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:

  • Scan what's new and mark channels as read
  • Add a reaction to a message, start a thread or show message actions
  • Jump from the All unread view to a channel to post a new message

Keep in mind: for now, all unreads is only available on desktop. Stay tuned for updates! 📰


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

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 also sort scientifically – a view tailored to how you use Slack.

Mark messages as read

Click Mark as read to clear that channel’s messages once you’ve finished reading them. You can also scroll to the bottom of the All unread 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 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 the icon to reveal a fresh batch of unread messages!

Message actions

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

Jump to a channel

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