Keysat
4becb76443
Operators selling via Keysat own their buyer-email path through their own app plus the existing webhook delegation, so a Keysat-side SMTP send path is redundant and a branding/double-send liability. The surviving need -- operator visibility into failures where the webhook channel itself is what's broken (dead-lettered endpoint, revoked provider key, expiring license) -- is re-homed onto StartOS notifications/health checks rather than a mailer Keysat ships.
