(Slightly paraphrased from a thread on ClassicCmp.)
In differentiating e-mail versus email, the hyphen — and the evolution over the years that accompanied the dropping of the hyphen — means this:
“E-mail” is bottom posting, some but never enough trimming, proper inline quoting, set off by chevrons, plain text and a stab at spelling and capitalization.
“Email” is top posting, fancy fonts, colours, background wallpaper, pictures and sounds with dancing kangaroos and yodelling jellyfish, no attempt too even try spelin and no trimming at all ever of the old crap, all of which has they're own dancing kangaroos.
