Any idea on stuffing a web font into a multipart message so the tracking-adverse email clients can still use it? Could be impracticable depending on volume anyway, 18k (size of font in example) extra per message isn't nothing.

It occurs to me that that would be a slick way to get around spam filters... Just have a character in your e-mail that maps to the "Cialis" glyph, for instance. :)

I like running my own mail server. It means I can null route people who think this is acceptable.
