How do they know they are HTML before they open them? Also, I read in plain text. If you want me to read it in HTML format, include a link to the web version and, if I'm interested, I will actually click on that - which has the added benefit of putting me on your site. Not many do that. 'If you want to read this in HTML format, click this link.' That works and I may very well click it. Edit: Never mind. I see they speak of unstyled HTML email, not plain text email. So, the email is still HTML, it's just not pretty. Chances are, I won't notice as I read in plain text most of the time.
