Translated documentation

Introduction

MJML is a markup language created by Mailjet and designed to reduce the pain of coding a responsive email. Its semantic syntax makes the language easy and straightforward while its rich standard components library shortens your development time and lightens your email codebase. MJML’s open-source engine takes care of translating the MJML you wrote into responsive HTML.

Installation

You can install MJML with NPM to use it with NodeJS or the Command Line Interface. If you're not sure what those are, head over to Usage for other ways to use MJML.
