SMPP (Short Message Peer-to-Peer) is the messaging protocol natively supported by mobile carriers’ back-end transmission infrastructures. Initiating a SMPP message requires a specialized direct connection to a carrier or messaging aggregator. Due to the dedicated nature of this connection, delivery reliability and throughput rate can be maintained at a constantly high rate. SMPP is the preferred method that alerts are sent by default. SMTP (Simple Mail Transfer Protocol) is the standard protocol used to transfer electronic mail from point to point. Its universal use and open architecture led wireless carriers to construct “gateways” to translate e-mail to their internal SMPP format and vice-versa. In the process, each phone number was assigned a domain (e.g. @messaging.sprintpcs.com or @vtext.com).
