Pulls 19 HTML email coding rules and 6 component patterns directly into your AI client so Claude or Cursor generates templates that actually render in Outlook 2007 through 365, Gmail, and Apple Mail. Exposes structured tools for fetching bulletproof button markup with VML fallbacks, spacing patterns, MSO conditionals, and dark mode handling. You'd reach for this when building transactional or marketing email templates and you're tired of AI hallucinating table structures that break in Outlook or forgetting inline styles. Also includes a playground with screenshot-to-HTML conversion. Available as an npm package or a hosted JSON-RPC endpoint if you don't want to install locally.
