I am developing an application in which I would like to send and receive SMS messages, and I am thinking about using email for SMS gateways because it reduces cost and another technology that I have to integrate. I have read the restrictions on sending SMS messages using free email gateways and SMS messages , and most of these restrictions do not apply to me:
- I'm not so good at formatting
- I do not mind guessing / asking for the actual email address or at least my user name.
- I can handle email replies
The problem I am facing is that, at least for some media (I just tested Verizon in the USA), when the responder answers, there is no indication that the message is responding. In contrast, AT & T saves the original SMTP Message-IDand object.
Are there any known solutions to this problem? This is actually not a global application (as long as it is not), so I do not mind hacker hacks here and there, as long as there is a way to track the response.
Edit: here's a sample email response cut out:
