Monitoring feedback loops is crucial because if enough people report your email as spam by clicking the 'this is spam' button, it doesn’t matter if the reader opted in or not, inbox providers will start blocking your email!

A FBL email is more than an unsubscribe request, senders should stop focusing on the unsubscribe portion of the FBL process and focus more on the recipient feedback portion of it.

Great advice from Jeanniey Mullen: "You'll never be able to please all the people all the time. That's why your e-mail program approach must remain consistent with your brand strategy and include both multiple touches and multimedia integration."
