Appendix D. EmailSend Using the Gmail Outgoing SMTP Server
D.3 Sending a Text Message to a Phone
To send a text message to a phone, the email needs to be converted to a text
message via an email to text message gateway. Most cellular providers have
an email to text message service for their phone subscribers. To send a text
message to AT&T Wireless phone subscribers, send an email to the (10 digit
phone number of the person’s phone)@vtext.com (
).
Most text messages are limited to 160 characters, so any email messages
greater than 160 characters will be truncated.
