Yeah, I came here to suggest pandoc too.

You can easily script mutt to include a plaintext file and an html one generated by pandoc, so that people reading your emails can fall back to a plain text version of your mails in case they can't view html.

If you folks have already done the legwork on this, could you please publish your setup?

Here is what I use.

  # convert markdown to html via pandoc
  # https://unix.stackexchange.com/questions/108485/send-    email-written-in-markdown-using-mutt
  macro compose \e5 "F pandoc -s -f markdown -t html \ny^T^Utext/html; charset='utf-8'\n"

Thanks!

Yes please! This sounds intriguing. I send plain text only from mutt but including HTML from Markdown via Pandoc would be very cool.
