Should we still ask newsletter subscribers this question and should we still make two copies of the newsletter (1 for html, 1 for text)?
Many online newsletter serivce don't ask if you want to use html format or pure text format anymore today. They just send you the html format. Even on some of the text only email tool, you can still read the email. And in the email, they may add a text line in the beginning tell you that if you cannot read html format email, go to that link to read the newsletter online.
Thanks!
