By default, SingleCase sends a large number of notifications to your email (e.g. a newly submitted task or a note in your Case) to keep you in control. But it can be annoying when there's a lot going on. You can then adjust this setting yourself.
In the menu, select "My name" -> "Mail and calendar settings".
2. Select the "Notification settings" tab.
3. Here you can choose which notifications to keep and which not to keep.
