Feedback Loop Request Form


Comcast offers a feedback loop service, operated by Return Path, free of charge, to parties sending large amounts of mail to Comcast members. The feedback loop (FBL) will forward any DKIM-signed email reported as spam back to the registered FBL email address associated to that domain. These emails are in ARF (Abuse Reporting Format). We highly recommend the use of a dedicated email address for this purpose.

A confirmation email link will be sent to the confirmation email address for each domain. Once your request has been approved, Feedback Loop email will be sent to the email address listed in the "Feedback Loop Email" field.
