I think we need to be clear, there's two issues here. 1. Receiving html emails in emacs 2. Sending plain-text emails in emacs I personally do not find 1. to be a problem at all. If the html gets garbled in my automatic html2text conversion (I use html2markdown) then opening it up in Firefox is just a keypress away. Easy. I agree that 2. is an issue, however in the rare occasions that I do need to write an html email, I just open up Outlook or Gmail or whatever. We don't have to be Richard Stallman about this. You can use another client when you need to. For me, 99% of the time emacs/mu4e is absolutely adequate, and better than the Outlooks/Gmails for a host of reasons. Let's not throw the baby out with the bathwater.
