 This gem is a no config solution for the wonderful [Premailer gem](https://github.com/alexdunae/premailer) to be used with Rails.
 It uses interceptors which were introduced in Rails 3 and tweaks all mails which are `deliver`ed and adds a plain text part to them and inlines all CSS rules into the HTML part.
