Using SMS/MMS Text Messaging with your mailing list
SMS and MMS are similar but different technologies for sending text messages to telephones.
You can add subscriber's telephone numbers to your list, and they will receive the emails as text messages on their phone. They can reply to the text message, and it will come back to the mailing list.
We will send the message to their telephone carrier via email, using a special domain name their telephone carrier gives us. While the email gets there within a few minutes, the time it takes for the carrier to send the text message can vary. Therefore, this service is not useful nor reliable if you need instant delivery.

MMS can contain text and graphics. While we won't send any graphics, the size of the text message can be fairly large.

Notice how some phone carriers have different domain names for SMS and MMS messages.
Typically smart phones can handle MMS messages, while basic phones are limited to SSM messages.
So the address you add to your list will look something like this
firstname.lastname@example.org Basic phone getting short SMS messages
email@example.com Smartphone getting longer MMS messages
Do not include parenthesis or dashes in the telephone number. Just digits.
Because SMS and MMS have size limitations, we will truncate long messages we send to telephone numbers.
SMS text messages are for older cellphones, and will have typically only receive the first 140 characters of the email message.
MMS will work on the newer smartphones (like the iPhone and Android), and can typically receive up to 3,000 characters of the email message.
In order to converse space, Headers, Trailers, and Physical Address will be automatically removed from outgoing messages.
Because the Click to Unsubscribe link is not included in text messages, we send a simple text email twice a month to all SMS subscribers. This text message asks your subscriber to reply if they want off your list.
