What US cell phone providers offer sms to email capabilities?

I've looked all over but found minimal on this. I would just like a list of carriers (cell phone providers, companies) that allow their users to send email via sms or text messaging.
ALSO: If you can send emails from a certain provider, what is the format? Is the number simply replaced by an email?
