Your default email address is used as your main contact method in Canvas and is added when creating your Canvas account. Email addresses are used to create Canvas notifications; they are not used as a contact method for other Canvas users.
If you add another email address as a contact method, you can change your default email address in Canvas.
In Global Navigation, click the Account link [1], then click the Settings link [2].
The User Settings sidebar displays your contact options. View your email address contacts under Email Addresses [1]. Your default email address displays a Star icon [2].
To select a new default email address, hover over the preferred default email address [1] and click the Star icon [2].
