Markdown to Email HTML Converter
Convert markdown to email HTML with inline CSS for Gmail and Outlook. Copy as rich text or HTML and paste into any email client. Free, no signup.
What Is a Markdown to Email Converter?
A markdown to email converter turns markdown into HTML that email clients render correctly: every heading, paragraph, link and table carries its CSS as an inline style attribute, because Gmail strips style blocks, Outlook ignores most external CSS, and neither supports the classes a normal web page relies on. The result pastes into a compose window or an email service as a formatted message rather than as asterisks and pound signs.
This tool renders your markdown, applies one of three themes, optionally wraps the content in a centered table, and gives you three ways out: copy as rich text, copy the HTML, or download a .html file. A plain-text version is produced at the same time. Everything runs in the browser.
How to Send a Markdown Email
- Write or paste the message in markdown in the left pane. Headings, lists, links, code and tables are all supported.
- Pick a Theme: Plain for everyday mail, Newsletter for announcements, Minimal for short notes.
- Leave Wrap in centered table on for a standalone email; turn it off when pasting into a reply.
- Check the preview, then click Copy as rich text and paste into Gmail, Outlook or Apple Mail.
- For an email service template, use Copy HTML or Download instead.

| Newsletter | Georgia, 16px; Helvetica headings with a rule under the title | Amber, underlined | Dark box, light text | Announcements, digests |
| Minimal | System font, 14px | Text color, underlined | Thin border, no background | Short notes, transactional mail |
Gmail Markdown and Outlook Markdown Notes
Gmail keeps inline styles on paste but drops anything in a <style> block and rewrites <pre> spacing, so code blocks use white-space:pre-wrap and an explicit font. Outlook for Windows renders with Word, which means no max-width on divs, no CSS margin:auto centering and unreliable padding on paragraphs; the table wrapper and per-element margins are there for it. Apple Mail and Thunderbird accept nearly everything.
Dark-mode clients invert colors on messages that do not declare them. The converter sets the text and background color on the wrapper and on code and table cells, and the downloaded document includes a color-scheme meta tag, which keeps light backgrounds light in Gmail and Outlook mobile.
When to Use a Markdown to Email Converter
Release notes, weekly summaries, onboarding sequences and incident reports are usually written in markdown first. A markdown to email converter gets them into the inbox without rebuilding the formatting in a compose window or hand-writing table HTML. Use the rich-text copy for one-off messages, and the HTML download when the same markdown email will be loaded into a sending service as a template. Pair it with the markdown to plain text tool when you only need the text part.
Frequently Asked Questions
How do I send markdown as an email in Gmail?
Paste your markdown into the left pane, pick a theme and click Copy as rich text. Open a new message in Gmail and paste; the headings, bold text, lists, links and tables arrive formatted because the clipboard carries an HTML version alongside the plain text. This is the fastest markdown to email path for gmail markdown users because no add-on is needed.
Does the output work in Outlook?
Yes. Outlook's desktop clients render HTML with Word's engine, which ignores style blocks and many CSS properties. The converter inlines every style as an attribute, uses table-based centering instead of flexbox or margins, and sets explicit colors, so outlook markdown pastes stay readable. Code blocks fall back to a bordered box when the client drops background colors.
What is the difference between Copy as rich text and Copy HTML?
Copy as rich text puts the rendered email on the clipboard so it pastes formatted into Gmail, Outlook, Apple Mail or Thunderbird. Copy HTML copies the full HTML document as text, which is what you paste into an email service's HTML editor (Mailchimp, SendGrid, Brevo) or save as a template. Download .html saves the same document as a file.
Why is the email wrapped in a 600px table?
Most email clients render a message at roughly 600 pixels wide before scaling, and a centered table with a fixed width is the layout technique that survives Outlook, Gmail and mobile clients alike. Untick Wrap in centered table if you are pasting into a reply where the surrounding message already sets the width.
Is the plain-text version used?
When you Copy as rich text, a plain-text version is written to the clipboard as well, so a client set to plain text still receives readable content with link URLs in brackets. You can also view and copy it with the Plain-text version output for the text part of a multipart email.
Is anything uploaded?
No. The markdown to email conversion runs in your browser. Nothing you write leaves your device, which makes the tool safe for internal announcements and customer emails.
