Subscriber displays as unsubscribed by "Reply Mail Management"
|Knowledge Article Number||000221979|
A subscriber is noted as being unsubscribed by Reply Mail Management (RMM), but RMM is not active in the account.
"Unsubscribed by ExactTarget RMM service based on subscriber Leave/Reply email."
In the header of emails, the Marketing Cloud automatically appends a list-unsubscribe message that contains an e-mail address for unsubscribing. Hotmail live and other providers use that link when offering subscribers an unsubscribe option in the e-mail.
This is in lieu of reporting it as junk. So instead of showing up as a spam complaint it shows up as unsubscribed by RMM. This also works the same when a subscriber sends an email to spam folders.
