You can configure which notifications you receive by email in your user settings.
To access user settings, click the User icon on the toolbar and then select Settings. Navigate to the Notifications section.
The Notifications section lists categories of events that trigger notifications, such as changes in an asset's stakeholders and new comments on an asset. By default, you receive an email notification each time an event occurs. You can disable all email notifications, disable event notifications by category and subcategory, and for some categories you can choose to receive an email summarizing events at an interval that you specify.

Note: Depending on which service you're in, the user settings page might appear differently and might show slightly different names for the sections.
