`hono-email` is an ESM library for rendering HTML email and plain text from `hono/jsx`. It focuses on rendering, normalization, validation, and email-oriented primitives.

## What it does

- Renders HTML email from `hono/jsx` components.
- Derives plain text from the same JSX tree through `render()`.
- Keeps strict email validation enabled by default.
- Minifies output by default, with optional pretty printing and widow control.
- Styles markdown content with the `Markdown` component.
- Supports `hono/css` class-based CSS-in-JS as a styling option.
- Applies Tailwind utility output through `Tailwind` build artifacts.
- Sends rendered email through transport adapters (SMTP, Resend, SendGrid, Postmark, Mailgun, Cloudflare Email).
- Provides bundler integrations through `@hono-email/tailwind-plugin`.
- Live-previews templates with real-time props editing using `@hono-email/preview`.

## When to use it

Use `hono-email` when you want to build email templates with JSX in a Hono or Bun/Node/Deno/Cloudflare Workers environment, and you need validated, email-client-safe output without managing a separate React dependency.
