react-email

React Email is a powerful, modern framework designed to simplify the complex landscape of cross-client email development. It enables developers to construct sophisticated, responsive email templates using familiar React syntax, eliminating the need for archaic, table-based HTML structures. By abstracting the inconsistencies between email clients like Gmail, Outlook, and Apple Mail, it allows teams to focus on design and content while ensuring consistent rendering across diverse platforms.

• Component-based architecture using specialized primitives like Html, Body, Container, Row, Column, and Section to manage layouts reliably.
• Integrated Tailwind CSS support via a specialized component, enabling utility-first styling with pixel-based presets optimized for email client limitations.
• Built-in live development server with hot-reloading and a browser-based preview interface for rapid iteration of template designs.
• Embeddable visual email editor based on Tiptap and ProseMirror for content management and no-code template modifications.
• Robust rendering engine to convert JSX/React components into raw HTML strings suitable for injection into any SMTP service or email API.
• Comprehensive compatibility layer that automatically handles the specific markup requirements for different email clients.

Usage notes and best practices include:

• Use the provided CLI tools (npx create-email) to scaffold projects and manage email templates in an organized directory structure.
• Always define brand colors, logo hosting (CDN), and style preferences before development to ensure consistency.
• Images should be hosted on a production-ready CDN; use the environment-aware URL pattern to switch between local development assets and production URLs.
• Avoid using CSS features like media queries where broad support is not guaranteed; rely on the framework's recommended layout components instead.
• Do not use template variables (e.g., {{variableName}}) directly in JSX components; instead, pass them through component props and use the PreviewProps pattern for testing.
• Integrate with popular transactional email providers like Resend, Nodemailer, SendGrid, Mailgun, AWS SES, or Postmark by rendering to HTML and passing the result to their respective APIs.
• The tool is ideal for building welcome sequences, password reset notifications, order confirmations, newsletters, and complex transactional notifications.
