mjml-raw
JSON →MJML component for embedding raw HTML that bypasses MJML processing. Used inside MJML templates to insert unparsed HTML, often for custom code, templating languages (e.g., Liquid, Handlebars), or pre-doctype content via position="file-start". Current version 5.3.0 (stable). Released as part of MJML monorepo with quarterly minor releases. Key differentiators: preserves exact output, supports minification hints with <!-- htmlmin:ignore -->, can inject content before <!doctype html>. Unlike similar components in other email frameworks, mj-raw is an "ending tag" and cannot contain other MJML components.
