Adobe needs a little tweak in the newsletter subscription options. If you click on the link, you are immediately unsubscribed with no recourse. It should take you a page to either opt out or update your subscription preferences such as updating your email address.
Thanks for the head's up. In case we need specifics of your set-up to help us troubleshoot, are you willing to share your email address with me? I'm Terri Stone, Create's content director, and my address is firstname.lastname@example.org.
