We've had an email recipient reply to one of our recent emails stating that they have unsubscribed multiple times but when we checked, the *replying* email wasn't in our database but the email we *delivered* to was in our database.
For the email in question:
"To:" shows firstname.lastname@example.org
In this case would the email@example.com be an alias, forwarding email, or retired email?
Is there a workaround to force MKT_TOK to associate unsubscribe action with the delivered email?
