Open   Activity from your sidebar to quickly review all of your notifications. Think of it as a place to focus your attention or to get caught up after some time away from Slack.

Work from Activity

When you open Activity, you’ll land in the All tab — a chronological feed of your notifications. Click each tab to switch between the different types of notifications, like mentions, replies to threads or reactions to your messages.

• A dot on a message indicates new activity.
• Use the Unreads toggle in the top-right corner of the navigation pane to only see new messages.
• Reply inline without leaving Activity, or click any message to jump to its original conversation. 

Note: If you've configured your notifications for all new messages in a channel, only those that mention you will show in Activity. 

Filter unread activity

Each notification type that appears Activity has its own filter. Using the filters, you can adjust the feed to see the latest unread notifications, or switch to All to revisit all your notifications.

All	View all your notifications in chronological order.
Mentions	Messages you’ve been mentioned in will be listed with the name of the conversation, the name of the person who mentioned you, and a preview of the message.
Threads	A list of replies to threads you’re following, or threads you’ve been mentioned in.
Reactions	When someone reacts to your messages, your Activity view will update to show the message and all of its reactions.
Invitations	View invitations to collaborate in Slack. This includes Slack Connect invitations, channels you’re added to, and canvases that have been shared with you.
Apps	View messages from apps, like Google Calendar invitations or updates from JIRA.

Take action on messages

Hover over any message in the feed to take the following actions:

•   Save for later
•   Mark as read
•   Open in new window

Or click the   three dots icon to:

• Open in  Home
• Turn off notifications for replies
• Set a reminder
• Copy the link to the message
  
  

Understand badges

You’ll see a badge on   Activity in the sidebar every time you receive a notification. Reactions to your messages won't trigger a badge, but you will be able to view which messages have new reactions as they happen.
