Application-to-Person (A2P) SMS
A2P SMS (Application-to-Person Short Message Service) is the process of sending mobile messages from an application to a mobile user, typically via an automated process, for marketing or service-related purposes.
A2P facilitates the automation of sending large volumes of messages, streamlining the delivery of critical messages such as two-factor authentication, emergency alerts, appointment reminders, as well as promotional and sales-type messaging.
