Experiencing issues sending email to SMS via AT&T involves navigating several factors. AT&T may block messages if they suspect spam or policy violations. A key issue is the use of an unsupported AT&T gateway for bulk sending, compounded by stringent CAN-SPAM opt-in requirements. For resolution, contacting AT&T support is crucial, alongside ensuring recipient opt-in and exploring dedicated SMS providers. Technical aspects include proper email authentication (SPF, DKIM, DMARC), and awareness of AT&T's SMS/MMS message limits. Alternative solutions involve push notifications, TCPA compliance is mandatory, and direct SMS gateways are preferable for high-volume sending.
