Your primary email address is your address TripIt sends emails.
If you have multiple email addresses in your TripIt account you can choose which email to make as your primary.
On both Android and iOS go to More > Settings > Email Addresses > then select the email address you wish to be your primary and tap Make this the primary email.
(Note: new trip creation emails are sent to the email address from which the vendor confirmation email was submitted.)
