If you upgraded and have activated the new card I would just ignore the emails. Maybe something is hung up in the system or the app. You could try and uninstall the app and reinstall it and see if that clears the email thing. I think someone else posted this same issue right after activating. If you are on Facebook or Twitter(both icons in the bottom righthand corner of this page) send them a message and see if they will stop sending them. Make sure to include your full name and email address in the message.
