Twilio is more complete and supports a lot more carriers and doesn't look like it came from an email address.

TextBelt is pretty sweet though if you want basic messaging.

Textbelt uses sendmail under the hood and keeps a list of carrier email domains. So you're actually sending emails to [e-mail]. Depending on the carrier, those text messages look a bit weird.

I checked the source to see what it's doing, and it actually is sending the text to every provider that has an email-to-text address, and therefore probably ignoring the returned failure emails.
