yeah, they exist, and you can google for a list easily, BUT there's issues.
For one, you have to know the carrier (or I guess send the email to all of them, but I could see that getting you blacklisted or something). Also, I think I've heard that they're less reliable and can get slow when a lot of people are sending to them.
Also, I'm pretty sure you'd have to use something if you want a shortcode. Having them put in an email address, though it would work, is kind of ugly.
