1. Click your workspace name on the top left, or click the bell icon.
2. Choose Preferences from the menu.
3. Click Notifications.
4. Under When I’m not active on desktop, check or uncheck Send me email notifications.
5. Click change to choose how often you receive them.

You can choose once every 15 minutes, or once an hour.
