The email address that recipients see is the same email address that you entered in your Contact Info. To change it, click Personalizer, then click Contact Info. If you enter an email address that has not previously been verified, then we will send you a new verification email. If you don't see the email for at least 15 minutes, check your spam or junk folder.
