Each message claims its row exactly once, re-checks consent at dispatch time, and leaves with the opt-out footer appended inside the send path.

EASTERNA STOP comes back. It's already handled.
The contact is unsubscribed before the webhook returns. A campaign mid-send skips them within one message.

Compliance is the architecture, not a checkbox.
One send path
Every message leaves through a single send path that re-checks consent at dispatch time and appends the opt-out footer itself. No template can forget it; no draft can bypass it.
STOP is structural
An exact STOP reply flips the contact before the webhook even returns. A campaign already mid-send skips them within one message.
Consent has a paper trail
Every contact stores when and how they opted in. Unsubscribed numbers can never be re-imported by accident.
