Mjml
MJML is a responsive email framework and HTML email compiler that translates simplified semantic markup into complex HTML. It functions as an email template engine designed to produce layouts that render consistently across a wide range of email clients.
The system provides a markup validation tool to check structural integrity and syntax before compilation. It also includes a version migration utility to upgrade older template files to newer language versions while preserving content and layout structure.
The toolset covers several capability areas, including command-line markup compilation with file change watching and programmatic rendering via a local library or remote API. It handles CSS inlining, HTML output optimization, and the inclusion of partial templates to support modular composition.
