I've been preaching for years to people that using HTML-enhanced email
is a questionable practice, and on a mailing list it's even worse.
There is no established standard for this usage, and graphic
attachments may or may not be handled, or handled as the sender
expected. On a mailing list it's a pretty sure bet that at least _some_
subscribers won't be able to see what the sender intended, so SOP on
the lists here is to just strip them off. An email with _only_ an HTML
MIME part is identified as spam.
Smart phones have complicated the issue since in my experience smart
phone MUAs are fairly brain-dead.
I tell my Mailman mailing list customers that spot color, font effects
(bolding, italics, etc) and simple layout are probably fine, but the
use of images, either embedded or attached, is dicey.
It used to be that HTML-ized emails were up to 10 times the size of
plain text emails, depending on the generating MUA. This is probably
still true, but bandwidth and storage capacities around the Internet
have risen over the years so that this isn't the problem it used to be.
