Introduction

MJML is a markup language created by Mailjet and designed to reduce the pain of coding a responsive email. Its semantic syntax makes it easy and straightforward while its rich standard components library fastens 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.

npm install mjml

git clone https://github.com/mjmlio/mjml.git && cd mjml

You can also run yarn build:watch to rebuild the package as you code.
