I really like the simplicity of the 'How it works' section and I will probably steal the concept for explaining parts of our build to new employees.
Are you open to pull requests? I forked this and added a couple of things that I'd be happy to contribute back to:<p><pre><code> -- Less support
-- added a Gemfile to bundle install the ruby requirements
-- added an npm preinstall task to run bundle install
</code></pre>
I tested and it's working locally
This is pretty cool; we've put a lot of work into sendwithus to solve many of these same problems (inline css at send time, staging versions of templates, and multiple types of api keys).<p>Kudos for having a README that actually makes sense.
