What is Release B?
Release B is a temporary suppression with an auto-expiry cooling-off period. When a recipient's complaint auto-suppresses them, they enter Release B — after the cooling-off window (configurable, default 30 days) they are automatically released back to the active queue. Manual and hard-bounce suppressions are permanent.
