HTML email is an abomination and should be put to sleep. Its only use is for advertisers to spam the hell out of your inbox. It takes up more disk space than is necessary. You don't need HTML to convey a simple message to someone. In the possible (but very rare) event that it is necessary, send the HTML file as an attachment so the recipient could then open it in a web browser. Save bandwidth and disk space; say *no* to HTML email.
