What does a Spam Complaint bounce mean?
A Spam Complaint occurs when a recipient manually marks an email as spam in their email client. This could in some instances be a mistake by the recipient but usually means they no longer want to receive emails from you or your customer that is sending them email.
Spam Complaints cause the address to become deactivated, so you won't be able to continue sending to them using Postmark unless they explicitly reach out requesting to receive emails from you or your sender again.
How do I fix it?
You should not be seeing many spam complaints (if any) but there is an action you can take to resume sending to them. If the recipient reaches out to you or your sender and wants to receive emails again, contact us at firstname.lastname@example.org and let us know to reactivate the recipient's address.
