SPAM COMPLAINT FEEDBACK LOOPS
Being an email marketer, spam complaints are a truth of life. You may have a strict opt-in policy or your email messages may be absolutely legitimate, but, at some point or other one or more recipients will knock the spam button and will lodge a complaint against you.
Feedback loop is a means to notify the ESPs that a user has reported mails they send, as spam. Feedback loop reports come in the form of an email with special headers, sent by the ISPs. Upon receiving, proper action for the ESP is to discontinue sending any future emails to the reporters address.
