What it does

Generates production-ready HTML email using MJML 4.x as the authoring layer. MJML's responsive components compile to table-based HTML that is compatible with Outlook 2013 through 365, Gmail web and mobile, Apple Mail, and other major clients. Output meets WCAG 2.1 AA accessibility standards (sufficient contrast, semantic structure, alt text). The skill self-activates when asked to create, compile, or troubleshoot any HTML email.

When NOT to use

• Marketing web page HTML — use design-html instead
• Animated web content or interactive landing pages
• Email rendering testing across clients (use a dedicated email testing service like Litmus)
