As I skimmed this I thought about reading text on my phone. When there is no formatting, the text flows pretty well. There aren't obnoxious colors or flashy imagery and the phone's dark mode gets respected. So, in our increasingly mobile-centric life, I think that HTML-less or minimal-HTML is probably a better reading experience.

That said, most people probably don't sit down to read text in emails most of the time, especially from a business.
