Our Feed Back Loop (FBL), managed by Return Path, can be found on our external resources page.
When users click "report spam", you can get a copy of the spam complaint through our Feedback Loop system. Ensure that you have an active FBL on each of your IPs and that you’re processing the complaints quickly. Many senders will treat a spam complaint as an unsubscribe and remove a name from their mailing list if the user clicks "report spam". There are several third-party tools available to help you manage your lists.
