When you mention a workspace group in a Notion page, all current members of that group receive a notification. But you may notice that members who have left the group still get notified when the group is mentioned. This happens because Notion sends notifications based on the membership list at the moment the mention is created, not the group’s current state. This article explains the technical reason behind this behavior and shows you how to stop notifications for former group members.
Key Takeaways: Why Group Mentions Still Notify Ex-Members
- @group mention snapshots membership at mention time: Notion records the member list when you type the mention and sends notifications based on that snapshot, ignoring later group changes.
- Remove the group mention and re-add it: Deleting the old @group mention and typing it again refreshes the membership snapshot so only current members are notified.
- Use individual mentions instead of group mentions: Mentioning specific people by name avoids the snapshot issue entirely and gives you full control over who receives notifications.
How Notion Group Mentions Generate Notifications
Notion workspace groups are collections of members that you can mention in any page using the @ symbol followed by the group name. When you type @group-name and select the group, Notion creates a special link that points to the group. At that exact moment, Notion takes a snapshot of the group’s current member list. Every person in that snapshot receives a notification when the page is published or updated.
The snapshot is stored as part of the page content. If you later remove a person from the group, the existing @group mention still references the old snapshot. Notion does not automatically update existing mentions when group membership changes. This is by design to prevent unexpected notification floods when group membership fluctuates frequently.
What Triggers the Notification
The notification fires when any user with edit access to the page makes a change that causes the page to be saved. Simply viewing the page does not trigger notifications. But if someone edits a property, adds a comment, or changes any block, Notion re-evaluates all mentions on the page and sends notifications to every email address stored in the snapshot.
Steps to Stop Notifications for Members Who Left the Group
You need to refresh the group mention snapshot so it reflects the current group membership. The only way to do this is to delete the existing @group mention and re-add it. Follow these steps for each page that contains the stale mention.
- Open the page with the stale group mention
Navigate to the Notion page that contains the @group mention. This can be a wiki page, a database description, a comment thread, or any other Notion block. - Locate the @group mention in the page content
Scroll through the page and look for the group name that appears as a highlighted link. It will look like @group-name and be clickable. - Delete the @group mention
Place your cursor just after the group mention and press Backspace until the mention is removed. Alternatively, select the mention with your mouse and press Delete or Backspace. - Type @ and select the same group again
Type the @ symbol, then type the group name. A dropdown list appears. Select the group from the list. Notion now takes a new snapshot of the group’s current members. - Save the page
Click anywhere outside the block or press Escape to deselect. The page auto-saves. Any future edits to this page will send notifications only to the current group members.
Repeat these steps for every page that contains the old group mention. If the group is mentioned in a database property, such as a select or multi-select field, you must delete the entire property value and re-add the group mention there as well.
Alternative: Use Individual Mentions Instead
If you need precise control over who gets notified, mention specific users by name instead of using the group mention. Type @ followed by a person’s name and select them from the dropdown. This bypasses the snapshot system entirely. Each mention is tied to a specific user account, and notifications follow that user even if they leave the workspace later.
If Notion Still Notifies Ex-Members After Refreshing the Mention
Ex-member still appears in the group membership list
First verify that the person has actually been removed from the workspace group. Go to Settings & Members > Groups, select the group, and check the member list. If the person is still listed, remove them by clicking the three dots next to their name and selecting Remove from Group. Then refresh the @group mention on your page as described above.
Notifications are delayed or cached
Notion may queue notifications for a few minutes. If you just refreshed the mention, wait 5 to 10 minutes and ask the ex-member whether they received a new notification. If they did, double-check that you deleted the old mention completely. Sometimes a mention remains hidden inside a toggle block or a synced block. Expand all collapsed blocks on the page and search for the group name using Ctrl+F or Cmd+F to find hidden mentions.
The group mention is inside a database template
Database templates in Notion store a snapshot of the content at the time the template was created. If the @group mention is inside a template, you must edit the template itself. Open the database, click the arrow next to the database name, select Templates, find the template that contains the mention, delete the mention, and re-add it. New pages created from the template will then use the updated snapshot.
Group Mention Snapshot vs Real-Time Mention: Behavior Compared
| Item | Group Mention (Snapshot) | Individual Mention (Real-Time) |
|---|---|---|
| Notification trigger | Snapshot taken at mention creation time | Current user account status at edit time |
| Updates when member leaves group | No — old snapshot remains in page content | Not applicable — mentions a specific user |
| Updates when user leaves workspace | No — snapshot still contains the user’s email | Yes — user account becomes inactive, no notification sent |
| Fix required to stop notifications | Delete and re-add the @group mention | No fix needed — inactive users are ignored |
Notion group mentions are a quick way to notify an entire team, but they rely on a static snapshot. Individual mentions give you real-time accuracy at the cost of typing each name. For teams that change membership often, individual mentions are more reliable.
Now you understand why ex-members receive notifications from old group mentions and how to stop it. The next time you update a workspace group, check all pages that mention that group and refresh the mentions. For critical notifications where you must exclude specific people, use individual @mentions instead of the group mention.
