The practice of sending Short Message Service (SMS) messages via an email gateway provided by a telecommunications carrier allows for text message delivery to mobile phones using an email client. For instance, an individual could compose an email addressed to a recipient’s mobile number followed by the service provider’s specific domain, resulting in the delivery of a text message to that phone.
This method offered a practical means of communication, especially when direct access to a mobile device was limited or when sending messages in bulk. It provided a historical bridge between traditional email communication and the rising prevalence of mobile messaging, offering convenience and accessibility before widespread adoption of advanced messaging platforms. It also helped to reduce costs associated with text messaging.
