If you have a meeting or you would like to suspend the notifications in AltaMail for a period of time, follow the steps below;

1. Open the app settings (View) - "Email Management" section and then tap on "Email Notification Settings"
2. Tap on the "Suspend notifications" in the top of the screen
3. Choose to disable notifications or just sounds and then choose a time

Note: If you have enabled Synchronize settings (View) then other devices will also have their notifications suspended, but it may take some time for iCloud to sync the changes.
