MJML: the only framework that makes responsive-email easy

MJML is a markup language created by Mailjet that simplifies responsive email development by eliminating complex HTML and CSS boilerplate. Using semantic syntax and a rich library of standard components, MJML compiles into responsive HTML automatically, reducing development time and email codebase complexity.
MJML is ideal for developers, marketing teams, and organizations that send transactional or marketing emails and want to eliminate the complexity of responsive email coding. It's perfect for those who prefer semantic, maintainable code over traditional HTML email templates.
