This looks really neat. I've spent _way_ too long on custom HTML for email signatures and email content without any tooling.. just an editor, some inline styles and a whole lot of pain. Looking forward to trying it out. No idea how y'all were able to figure out how to compile the dev-written code down to email-compliance for renderers as far back as you have, but kudos if it all works well. I could never get over how many different renderers and versions there are in the wild. Email is a TOUGH place for styling and it seems like Litmus just dominates everything else in the marketplace.
