EOTS (Email Of The Species), the gem for easily declaring your email types and their fields, is now at version 0.0.2, and now allows HTML in labels and captions. (Just be aware, these should therefore be hardcoded in an initializer, never using stored user input!) Rubygems info is at https://rubygems.org/gems/eots , code is at https://github.com/davearonson/eots , and a site that uses it (mine) at http://www.Codosaur.us (but please don’t send me emails just to test it).
