What problem does it solve? Building 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 produce email templates that respect these constraints from the start, avoiding broken layouts and rendering bugs. ## Core Features & Use Cases - Component-Based Email Templates: Build welcome emails, password resets, order confirmations, notifications, and newsletters using React Email components with Tailwind styling via the pixelBasedPreset. - Email Client Safety Rules: Enforces table-based layouts, pixel units, border type declarations, box-border buttons, and PNG/JPG-only images so templates render consistently across clients. - Sending and Internationalization: Covers rendering to HTML or plain text, sending through Resend and other providers, and multi-language support with next-intl, react-i18next, or react-intl including RTL languages. - Use Case: Ask for a password reset email for your SaaS app, and the agent first asks about brand colors, logo format, and production asset hosting, then generates a template with correct static file handling and dev/production image URLs. ## Quick Start Ask the agent to create a welcome email template with React Email for your product, providing your brand color, logo file, and production asset hosting URL.
