Solution
Issue Resolution
This message appears when someone has unsubscribed using a special 'list-unsubscribe' option automatically contained in Marketo emails, as well as most other reputable marketing emails. This 'list-unsubscribe' feature is an email address contained in the background header information of the email. Any time someone sends an email to this address, their email address is unsubscribed from your database. This is almost always done by that person's email client, using their inbuilt 'unsubscribe' features, such as the ones in Outlook, Gmail, or other common email clients.
