A FBL is an agreement between the sender (Circulator) and the recipient (ISP). If a subscriber complains about an email they received (marked as SPAM), Circulator will automatically unsubscribe the user from future email campaigns. By unsubscribing users who complain, marketers reduce their overall complaint rate per IP or domain, ensuring that targeted mail is much more likely to reach subscribers who actually want to receive it.
