CF7 monitors use WordPress 6.8.3 / Contact Form 7 6.1.2; other monitors are simulated HTML forms. All receipts use a fake provider. A receipt at our controlled monitoring mailbox does not prove delivery to a client inbox, spam avoidance, or CRM creation. No real email is sent. Pause, revoke and draft reset cancel queued Worker clicks. A browser command already executing may have submitted; cancellation cannot undo it.
