What problem does it solve? Creating HTML emails that render correctly across Gmail, Outlook, Apple Mail, and Yahoo is notoriously difficult because email clients lack support for modern CSS like flexbox, grid, media queries, and SVG. This Skill guides AI agents to build email templates with React Email components that follow email-client-safe patterns automatically. ## Core Features & Use Cases - Component-Based Email Templates: Create welcome emails, password resets, order confirmations, newsletters, and notifications using React Email components with Tailwind styling and the pixelBasedPreset. - Email Client Safety Rules: Enforces table-based layouts, border type specifications, box-border buttons, and rejects SVG/WEBP images, flexbox, media queries, and dark: selectors that break in email clients. - Sending & Internationalization: Render templates to HTML or plain text, send via Resend or other providers, and add multi-language support with next-intl, react-i18next, or react-intl. - Use Case: A developer needs a password reset email for their SaaS app. The Skill asks for brand colors and logo format, then generates a template with proper static asset handling, dev/production URL patterns, and PreviewProps for testing. ## Quick Start Ask the agent to create a welcome email template with React Email, providing your brand color, logo file, and production hosting URL.
