Agreed wholeheartedly. I'd love to see email clients embrace markdown rendering (and sending) as an alternative to HTML. For stuff like links, headings, bulleted lists, tables, etc. in a single page, markdown is perfect. Emails rarely exceed the complication of a readme, and markdown works amazingly for those. Even better: it remains totally readable in its raw unrendered form. So you're not really forcing anyone else to adopt your syntax, just... nudging.
