MJML is a markup language and open-source engine that compiles semantic, component-based markup into responsive HTML email that renders reliably across email clients, including Outlook. It is available as an npm package with a CLI, a Node.js API, and an online editor.
Use cases
- build responsive HTML emails without hand-coding table layouts
- generate email templates that work in Outlook and Gmail
- compile MJML files to HTML from the command line
- create reusable email components for marketing campaigns
- integrate email template rendering into a Node.js build pipeline
When to choose
- you need responsive emails that render consistently across many email clients
- you want a component-based, semantic syntax instead of nested HTML tables
- you want a mature, widely adopted tool with CLI, Node.js API, and editor plugins
When to avoid
- you only need plain-text emails
- you need pixel-perfect custom HTML beyond what the component library supports
- your stack has no Node.js or JavaScript tooling and no community port fits
