Enrolling in feedback loops (FBLs) is an important deliverability best practice, allowing you the opportunity to remove or suppress subscribers from your list who no longer wish to receive your email. This helps you manage spam complaint rates, which is an important reputation metric that mailbox providers use to decide whether they will deliver your email to the inbox, spam folder or if they will block your email.
Save time setting up and managing Validity-hosted complaint feedback loops by using our Universal Feedback Loop. The Universal Feedback Loop is a single FBL management tool to simplify the configuration process and coordinate subscriptions in one location.
