I do not believe HTML email is going to disappear any time now. In fact, I expect we will see an increase in HTML email which suggests we need guidelines, not proscription. I think in the interests of furthering discussion on this subject, a poll would be useful.
Personally, I care a lot less about this subject than I used to. I’m still no fan of HTML email, but it doesn’t bug me the way it once did. Formatting in email can be useful and attractive. The security concerns it raises aren’t very relevant to me since I use a Mac (though I’m still concerned for all the Outlook users out there). Even command-line pine displays the plain-text alternate properly for most HTML emails these days.
At its best, HTML email highlights the strong points in a message. At its worst (for me), HTML email is a minor annoyance, sometimes resulting in tiny font displays — but nothing I can’t get around by punching Cmd-+ on the keyboard. There are a thousand things under heaven and earth more worthy of getting het up about. What about you? Have your feelings about HTML-formatted email changed over the years?
