It would be nice if the email could be modified, but that's just a small thing. Or a custom message.

What language did you use, if you don't mind my asking?

I am sorry but what do you mean by modified email? I used sinatra(http://www.sinatrarb.com/) to build the web service and ruby for back-end. It is hosted on heroku. :)
