Zenith is an email framework made easy using SASS.
To get started, you'll need SASS and Compass.
Install compass:
$ gem update --system
$ gem install compass
If you need more information about compass installation, please refer to its documentation.
To inline, I'm using premailer.
Once you have it installed, you just need to run the .rb ruby file I've set up by putting the following into your terminal/command line application
$ ruby config.rb
This takes your email.html from your templates folder and saves it into email.html in your inlined folder.
