Cox communications a very large US based ISP have recently suspended their feedback loop.

A feedback loop is a way of an ESP or marketing department to know how many spam complaints they are getting from subscribers and automatically unsubscribe them from their lists to ensure that their spam complaint percentage remains low to ensure good future deliverability to subscribers who do wish to continue to receive their mailings.

The feedback loop website at http://fbl.cox.net now says “Thank you for your interest in the Cox Feedback Loop Service. However, at the present time, we are no longer accepting applications for new feedback loops. Note that this is a temporary change, and we do plan to offer new signups again in the near future, but currently a specific date is not known. Please check back here periodically for updates.”

There are rumours around the internet that applications for the feedback loop service are still being approved but months after the applications have been made. This would indicate that cox have been swamped by the shear amount of applications being made and they have closed their service to be able to clear the backlog.

If you have applied and not yet received your approval email, don’t panic the chances are your application will still be approved. If you have not yet applied, Email Manual will post again to let you know when the service has been resumed and applications are being accepted.
