# Unsubscribe from a notification flag

> Verifies the unsubscribe token and disables the named notification preference for that member, or, for mail no preference governs or mail sent to an email list, stops that category of mail for the address. Safe to submit more than once. Accepts the RFC 8058 List-Unsubscribe-Post one-click body, taking the token from the query string when the body carries only List-Unsubscribe=One-Click.
