Emails that come from the portal are automatically redirected once the email address on a user's profile is changed but marketing emails are not automatically updated. This list has to be changed manually. Once you've confirmed that the updated email address is showing on the user's account in both places, please escalate.

I apologize that you are still receiving emails at your old email address, please allow me just a moment to create a ticket to request that the Administrator update your information on their email list.
