How Do I Sign Up for Comcast's Feedback Loop?

Feedback Loop Policy

This page is intended to provide information about Comcast's feedback loop program

How to join and how the information can benefit senders.

Feedback loop data is generated by user complaints as they make use of the "This is Spam" reporting mechanism.  When a user submits a message through this system an ARF formatted report will be sent to the sender in an ARF formatted report.

All feedback loop reports will contain the full headers of the message sent, but are scrubbed of Comcast customers e-mail addresses.  Under no condition will the Comcast customer's e-mail address be added back to the message for purposes of the feedback loop.

In order to subscribe to Comcast's Feedback Loop, you must be the party responsible for a server that sends mail to Comcast customers.  If you are the owner of a service hosted on a shared mail server, it is recommended that you have the server owner contact us to sign up.

There is a 7 – 14 day window for approvals.

To sign up for Comcast's Feedback Loop, please visit http://feedback.comcast.net

To sign up for Comcast's DKIM-based Feedback Loop (still in early BETA, with limited support), please visit the signup page

Comcast reserves the right to suspend or discontinue providing feedback to any party at any time.
