Definition
Email sender recovery is the process of restoring deliverability after your sender reputation or domain has been damaged, causing mail to land in spam or get rejected. It addresses the cause and rebuilds trust slowly.
A typical recovery plan includes: identify and stop the harmful behavior, clean your list of bad and unengaged contacts, secure re-permission, warm up sending gradually, and monitor metrics and feedback as you rebuild.
Recovery takes time; providers rebuild trust based on consistent, improved behavior rather than sudden volume. Fix root causes, demonstrate sustained good practice, and use monitoring to confirm recovery before scaling back up.
