The Inbox allows you to provide an alternate email address (in addition to the primary email address established with the account). To add an alternate email address, you must successfully log into the Inbox first.
Step 1. Navigate to the “User Info” section displayed within the navigation bar. After clicking “User Info”, select “Preferences”.
Step 2. After selecting “Preferences”, you should be directed to the “Preferences” page. Provide a valid email address for use as an alternate email address.
