Feedback Loops (FBLs)

Feedback loops (FBLs) - often called complaint feedback loops.  This is complaint data collected by Mailbox Providers which provided to  anyone that has signed up for these FBLs. 

This data is collected directly from the recipients who click on the ‘report as spam’ button within the Mailbox. This complaint message then gets returned to the originating sender (or  ESP/Bulk mail provider) through a designated email address that the  sender has set up.
