Preview SMS format when sending email to SMS

Question

I'm using carrier-specific addresses to send email to SMS, which works fine. In reference to the answer of this question Limitations on SMS messages sent using free email->SMS gateways is there any websites or other resources that list the format that is delivered for each carrier. ATT for example delivers the SMS with some added formatting that is not present with T-Mobile.

I realize this is not a coding question, but since I can only see this question arising for someone that is creating email to SMS specific applications, it seems relevant to SO.

Answer 1

I spend a lot of time working with SMS (I work at Twilio) and I don't know of such a thing, but I can't say for sure.
