I've yet ever to see HTML, RTF, nor any other fancy presentation used to make
email easier to read or to understand. For web pages, yes, but never yet for
email. It's used to call attention to the message, to show off the sender's
purported design skills, or to give away that the sender doesn't know how to
send plain text.
Very often the choices involve foreground and background colors with very
little contrast, nearly illegible fonts, or other things that make the
content considerably more difficult to read.
