Opt-out keyword handling must be declared, not assumed

The requirementstatement

The campaign must declare an opt-out keyword set, and that set must be the one the sending platform is configured to honour.

Why this rule existsrationale

We cannot observe runtime STOP handling before a campaign exists, but we can observe whether anything was declared at all. An empty or single-keyword declaration is the reliable predictor of a platform that honours only STOP, which is narrower than the law now requires.

How to fix itremediation

Declare the full keyword set your platform honours, then verify in the platform that each one actually triggers an opt-out. The declaration and the configuration must match.

A compliant exampleexample

STOP, QUIT, END, REVOKE, OPTOUT, CANCEL, UNSUBSCRIBE

Notesnotes

Registration-side twin of the runtime obligation. Verifies the declaration, never the behaviour.
