Email.md Turns Markdown Into Production-Ready HTML Emails
A new open source tool called Email.md is solving one of web development's most painful problems: writing HTML emails that render correctly across dozens of email clients.
The Email Rendering Nightmare
HTML email development has barely evolved since the early 2000s. Developers must contend with:
- Table-based layouts — most email clients don't support modern CSS Grid or Flexbox
- Inline styles only — Gmail strips
<style>tags from<head> - Inconsistent rendering — Outlook, Apple Mail, Gmail, and Yahoo each interpret HTML differently
- Dark mode complexity — manual

The tool then compiles this into fully responsive, email-safe HTML that works across all major clients.
