Email Feedback Loops(FBLs)

Managing the reputation of your IP addresses is an important step in ensuring that emails sent by your customers reach their destination. One important step in maintaining the reputation of your IP address is joining an email Feedback Loop(FBL). An FBL is a service provided by many webmail and internet service providers. What an FBL does is, it generates a report each time an email is reported as “spam”, and it sends that report to the owner of the IP address from which that “spam” mail originated.
