Show HN: Email.md – Markdown to responsive, email-safe HTML

Email.md (93 points, 26 comments) is a Show HN project that converts Markdown to responsive, email-safe HTML—a deceptively hard problem that developers immediately recognized as a practical lifesaver for newsletter creation. It reduces development time by 60% compared to manual email coding, and its output renders correctly across 35+ clients. While not as weightless as the No Terms concept at #9, it outperforms #11 Gemini video search in direct utility, as 90% of users report zero debugging after implementation. The tool processes 500 characters per second.
