@sun @thatguyoverthere If it can't do white text on yellow background I'm not interested :blobcatdevil:

HTML emails are problematic due to the fact they are freaking websites read by web browsers. So they can be used for evil or just graphical design is my passion/looks nice on my screen emails. Not to mention all the fluff like pixel trackers, hiding link urls, sending 6mb images scaled down to tiny icons on the signature etc.

Markdown or similar is way better. Or just plain text with some ASCII "formatting" and anchors for images. (As in: described in the attachment 3, or [3] etc whatever citation/anchor you prefer). There's plenty that can be done with plain text.
