On Collage, you can use different emails for your account login and for the notifications you will be receiving from the system.
To change your notification email, click on your name in the top right corner and select Personal Settings. Under the Account Preferences section, click on the Notification Email dropdown menu to select a different email for your notifications.
Note: Your Login Email is the email address you use to log in to Collage and can also be changed under your Personal Settings. Your login email address is used by default for notifications. If you don't have another option available in the dropdown menu, please make sure you have specified your work email under My Info > Personal > Contact Information.
