You have total control over push notifications you receive for each Workspace and List. By default, notifications are on for all Workspaces and Lists. You can choose to turn them off for each workspace or individual list.
Navigate to the workspace settings, and then press Notifications to open the workspace notification settings. From there, you can select between Watch, Mention, or Ignore.
Navigate to the list and press the bell icon at the top format menu to open notification setting for that specific list. You can have Workspace notifications on, but choose to turn notifications off for particular lists inside.
