I'm with you on this one, though I didn't realise we were extreme!

Plain text cuts all the cruft and I can reasonably expect emails I receive to largely look similar so I get good at extracting relevant information.

Every client I have, desktop and mobile, displays and sends in plain text only and I'm pleasantly surprised how infrequently this breaks anything completely and how often it exposes tracking links etc.
