Over the weekend, I published a Ruby gem called EOTS (Email Of The Species). It's a Rails engine that lets you programmatically declare types of emails your app will let users send from forms, including generating the routes and forms, handling submission, etc. See eots | RubyGems.org | your community gem host for gem details, and GitHub - davearonson/EOTS: Rails gem for describing, showing forms for, and delivering, multiple kinds of email for code.
