This gives Claude the context to build React-based email templates that actually work across email clients. It covers the full workflow: scaffolding projects, using the dev server with live preview, composing emails with pre-built components like Button and Container, and rendering to production HTML. The skill enforces practical constraints like pixel-based Tailwind instead of rem units, table-based layouts instead of flexbox, and proper static asset handling between dev and production. It also handles the Resend integration for actually sending the emails. Useful if you're building transactional emails or need to embed an email editor in your app without fighting Outlook's ancient rendering engine.
