The process involves routing messages originating from an electronic mail system through a specialized service that translates and delivers them as Short Message Service (SMS) text messages to mobile devices on the AT&T network. This functionality allows users to send text messages to cell phones directly from their email accounts, using a specific address format provided by the wireless carrier.
This capability provides a convenient and often cost-effective method for sending alerts, notifications, and reminders to individuals who may not always have access to email. Its roots lie in the early days of SMS technology, when bridging the gap between email and mobile communications was essential for time-sensitive information dissemination. Historically, it served as a foundational element in early mobile marketing and customer service strategies.
