Why You Should Design in MJML Instead of Raw HTML Tables

Writing HTML tables for email clients like Outlook desktop is notoriously difficult. Learn why Mailjet Markup Language (MJML) is the industry standard for responsive email compilers.

Designing responsive emails is notoriously challenging because different email apps render HTML differently. While Apple Mail uses modern WebKit standards, desktop versions of Microsoft Outlook rely on legacy Microsoft Word rendering engines.

Historically, developers had to write hundreds of lines of nested

tags and proprietary Outlook conditional comments to keep emails from breaking on desktop computers.

The Modern Solution: MJML Framework

MJML (Mailjet Markup Language) is an open-source markup language created specifically to solve email client compatibility.
