Email feedback loops (FBLs) allow email receivers to tell a sending network about the complaints their users are generating about email originating from the sending network. By tuning in to FBL data, sending networks can identify problematic email traffic originating from their IP address space, such as spam messages. This information can help to pinpoint and then shut down spammers.
FBL providers use two main methods to determine the destination to which feedback messages will be sent:
If you send email from a dedicated IP address which is under your control, then you should register with all major feedback loops in order to make sure you are staying on top of any spam originating from your IP address. If you do not control the IP address from which you send email, then your service provider should be registered.
Many large email receivers provide FBLs, which you can freely register for by clicking on the links below:
Google’s Gmail service also offers a feedback loop, which is currently in beta. To indicate your interest in the Gmail FBL, visit this signup form. Not all senders will be accepted into their FBL program.
