Web application to send SMS email

Is there a web application that will let me send SMS email? Some services don't seem to support receiving normal email.

From web app Casebash

• Only the cellular phone carrier can decide whether you can send SMS via email or not. Here's how to reach people on the most popular carriers:

  T-Mobile: phonenumber@tmomail.net
  Virgin Mobile: phonenumber@vmobl.com
  Cingular: phonenumber@cingularme.com
  Sprint: phonenumber@messaging.sprintpcs.com
  Verizon: phonenumber@vtext.com
  Nextel: phonenumber@messaging.nextel.com

  where phonenumber = your 10 digit phone number

  If you have some programming skills, you could make use of an SMS API (such as ZeepMobile or Twilio) and build a database associating emails to an SMS phone number. Then you could send emails to "phonenumber@yourappname.com". The app would receive the email and redirect the message to the appropriate phone number.

  Casebash : Sorry, the question wasn't the clearest. [This](https://www.billmonk.com/about/sms) is what I meant by SMS email

  GoodEnough : @Casebash, simply sending an email to that address doesn't work? Does the service reply with some kind of error message?

  Casebash : I'm not sure what happened, testing again

  Casebash : @GoodEnough: Actually it does seem to accept normal email, just really slow about it!

• I wouldn't recommend using the email to SMS function most carriers provide for 3 reasons: (1) the email address seem to change over time (I've had mine change with my carrier a few times) and (2) some carriers charge to receive email to SMS messages and (3) it's annoying to read, since I know some of them require you to respond with "Read" or similar before seeing the who message.

  I've been using Twilio for voice and I've been quite impressed. I'm sure their SMS system isn't much different. You also wouldn't need to have much programming knowledge, although it would be a good idea to provide security.

  There is also a similar quesiton on Pro Webmasters.
