SMTP/E-mail Protocol

The SMTP/E-mail interface is ideal for sending SMS messages from applications that already support outgoing mail.

This interface converts mail to SMS and sends it to the end user. Sending an SMS message is done by sending e-mail to: <phonenumber>

Method #1: Direct connection to mailserver:

Connect directly to our smtp (e-mail) server at and authenticate with your username and password. Send an e-mail to <phonenumber> or <phonenumber>. The body of the e-mail is converted to a SMS and sent to <phonenumber>.

Method #2: Routed e-mail
