}emailmd converts markdown into responsive, email-safe HTML that works across Gmail, Outlook, Apple Mail, Yahoo, and every other client.
v0.3.0 migration:
render()is now async. Update calls fromrender(md)toawait render(md). Requires Node 20+ (MJML 5).
Bar charts, progress meters, sparklines, KPI tiles, step trackers, and star ratings, each written as a plain markdown list:
[KPI tiles, a bar chart and a sparkline, rendered by emailmd from plain markdown lists]
They are drawn from table cells and text glyphs rather than images or SVG, so they still render when the client blocks remote images, and they redraw themselves in the plain-text part instead of collapsing to a list of numbers. See the directives reference.
emailmd also ships with a command-line interface.
Run emailmd --help for all options.
@emailmd/react provides a live-preview hook (useEmailmd), an <EmailPreview /> iframe component, and <EmailmdBuilder /> — the full builder as a drop-in component for your own app.
emailmd ships a Model Context Protocol server, so an AI assistant can render, lint, and preview emails for you. It exposes three tools — render (markdown to email-safe HTML), lint (flag deliverability problems without rendering), and read_docs (look up emailmd syntax) — over either transport:
Published to the official MCP registry as dev.emailmd/emailmd. See the MCP docs for per-client setup.
Prefer plain context over tools? emailmd is just markdown, so AI is great at writing templates. Feed the full docs to your AI tool:

Render an email
Render emailmd markdown into email-safe HTML. Returns html (the complete email document), text (the plain-text MIME part), meta (frontmatter), warnings (non-fatal repairs made while rendering; aim for none), htmlBytes, and previewUrl (a live browser preview of this exact document to share with the user).
minifymarkdown必填partialsLint an email
Check emailmd markdown for deliverability, accessibility, and readability problems without rendering it: missing alt text, http:// links, Gmail's 102KB clip limit, generic link text, spam-trigger phrases, and more. Fix warnings before sending; suggestions are sometimes intentional (e.g. transactional emails without an unsubscribe link).
markdown必填partialsRead emailmd docs
Fetch emailmd documentation from emailmd.dev. Call with no arguments for the index of all pages; pass page to read one (e.g. 'buttons', 'frontmatter', 'theme', 'directives/hero'). Read the relevant page before using syntax you are not sure about.
