## What it is
emailmd is a TypeScript library and CLI that converts markdown into responsive, email-safe HTML (via MJML) that renders correctly across Gmail, Outlook, Apple Mail, and Yahoo. It also ships a React component package, a live-preview builder, and an MCP server so AI assistants can render, lint, and preview emails.

## Use cases
- convert markdown to email-safe html
- build transactional emails without writing html
- create responsive newsletters that work in outlook
- generate plain-text versions of html emails
- render email templates from markdown in node
- let an ai assistant write and lint email html via mcp
- embed an email builder in a react app

## When to choose
- you want to author emails in markdown instead of nested tables and inline styles
- you need emails that render reliably across major clients including Outlook
- you want automatic dark mode and theming from frontmatter
- you need both HTML and plain-text MIME parts from one source
- you want an MCP server or React builder for email authoring workflows

## When to avoid
- you need pixel-perfect, highly custom email designs beyond the 80% of common layouts
- you are not on Node 20+ or your stack is not JavaScript/TypeScript
- you need a guaranteed-stable API before 1.0, since breaking changes may occur between minor versions
- you already have a mature email templating pipeline (e.g. MJML or React Email) your team knows well
