Maizzle is a framework for HTML email development.

It’s powered by Tailwind CSS and an email-tailored, custom Node.js build system that enables various transformations necessary for HTML emails.

A series of markup and styling hacks that exploit HTML interpretation quirks of various web email services can be hacked to intentionally vary message appearance between services. Coupled with forwarding, which further transforms the email using service-specific quirks, you can make a game where different paths of forwarding across services trigger different appearances.
