Processing feedback loop results is an important part of list hygiene. After a recipient complains, they have a reasonable and legal expectation to receive no further emails from the sender.
A feedback loop (FBL) is provided by many ISPs as a forensic tool, and is typically sent in Abuse Reporting Format. You must be able to process this format.
An ISP routes complaint reports back to the originating network by using a predetermined email address (typically
email@example.com) so that complainants can be unsubscribed.
If you see a sudden change in FBL volume or type, you should investigate the cause.
- Was the wrong database used?
- Was a purchased list inserted?
Keep your email lists clean and fresh by promptly removing complainants.
