Nothing that cannot more elegantly be solved by using MarkDown ...

... or common sense.

I don't want to parse Markdown when I read emails.

(and I don't have common sense either)

Or you could say at a plaintext email first paragraph: You have to use your own fun/gun for this, and just type in plain text.

... which is perfectly ok, because MarkDown nicely degrades to plain text.

As long as the varient of Markdown supports tables, vanilla markdown is laking in that area.

Which e-mail client can render markdown?
