Feedback Loop (FBL)

A feedback loop is a way for mailbox providers to send complaints from their users to the sending organization.

This can be done via the use of a “This is Spam (TIS)” button or manually via a helpdesk.

Feedback loops send reports in MARF format and are usually opt-in services. Not all mailbox providers offer FBLs.
