I was considering purchasing IntelliSMS but was wondering about the functionality with my PHP form handler. The clients mobile number is a required form field and as the PHP form is passed across my server after submit I want a text to the clients email immediately i.e. "we have received your application, blah,blah" does IntelliSMS offer this facility and if so what should I be buying as I note there's about 4 opptions on the home page.
