Stop Hand-Coding HTML Emails: JSX Templates, Multi-Provider Sending, One TypeScript Library
Short summary
This TypeScript library replaces hand-coded HTML email templates with JSX components, automates Outlook-safe markup, dark mode, CSS inlining, and plain-text fallback rendering via React SSR. It abstracts email providers (Resend, SES, SMTP, SendGrid, Postmark, Mailpit) behind one send() interface, enabling single-line provider switches and failover strategies. Type-safe props and theme context prevent common bugs.
- •JSX email templates with server-side rendering, auto-inlined CSS, dark mode, and plain-text fallback
- •Multi-provider abstraction (Resend, SES, SMTP, SendGrid, Postmark) with one-line swaps and failover support
- •Type-safe template props caught at build time and theme context for consistent rebranding
