React Email 5.0

React Email 5.0 introduces several new features and improvements, including a Dark Mode Switcher that simplifies theming across different email clients, integration with Tailwind 4 for more efficient coding and improved email rendering, and Resend Integration, which allows teams to collaborate on email templates in real-time using a visual editor. The update also includes eight new components, such as avatars, stats, and testimonials, to enhance email design. The platform has seen significant growth, with a 117% increase in weekly downloads and contributions from 182 open-source contributors. The latest version supports React 19.2 and Next.js 16, and users are encouraged to update both React Email and @react-email/components packages to maintain compatibility with Tailwind 4.
