MJML for Web

Introducing MJML for responsive email design

MJML is a specialized markup language created to simplify building responsive emails. It abstracts away many of the quirks of traditional email HTML, producing clean, production-ready output that behaves consistently across a wide range of clients and devices.

Why responsive email matters today

Recipients open email on desktop clients, mobile phones, tablets, and webmail services that all render HTML differently. Designing emails that adapt to varying screen sizes and inconsistent client support is essential for getting your message read and for preserving branding and layout integrity.

How MJML helps you

As an open-source tool, MJML focuses on generating HTML that follows best practices for email compatibility. It reduces the amount of low-level, client-specific markup you need to write, letting you concentrate on content and layout rather than hacks to support legacy clients.

Key capabilities and conveniences

• Flexible multi-column layouts that adapt to small and large screens
• Interactive image carousels and other rich components you can drop in easily
• Support for both mobile-first techniques and hybrid strategies for robust rendering
• Options to work in a browser-based editor or compile templates locally on your machine

Getting started quickly

Install MJML through your package manager or try an online editor to prototype. Write MJML tags for common structures (sections, columns, text blocks), then compile the template into HTML that you can send through your email service provider. This workflow speeds up development and testing.

Final thoughts

Well-designed, responsive emails are more important than ever. Using MJML streamlines the process of creating adaptable, client-friendly messages so your campaigns look great and perform reliably across platforms.
