It’s Official: email not e-mail

I think anytime (not any-time) a culture can eliminate a hyphen and create a sensible compound word, the language moves forward.

The swiftness of the change probably stems from the consensus rejection of "e mail" and which then led to folks finding the addition of a "-" tedious (except as an emoticon!).

I write "any time" as two separate words, but maybe that's just me.
I hope we never go down the German route of mashingwordstogetherlikethis, but you did say "sensible", which imo excludes that :)

In formal writing, and especially resumes, I always hyphenate e-mail. It looks better to me.

I just received this in an e(-)mail. This matter is now surely resolved once and for all:

I totally disagree. I'm gonna miss the hyphen. The hyphen is wide open space: rest your eyes, take your time, figure it out. Sure it takes more brain bits to process five characters than four, but we've now created a row of letters that are ugly when viewed close together (to the glancing eye, it might read 'snail') to create a word that forces one letter to carry a syllable alone.
("We're gonna have another 'awhile' on our hands!").

I have always advocated against the hyphen in this case. I believe Winston Churchill would have too.

I never take the AP style guide as the definitive reference. They will always lean on the side of less space taken up in column type. An anacronism in the Internet age. For example they have advocated against the serial comma for years when every other reference still calls for one. I will stick with:
e-mail
E-mail for sentence caps
E-Mail for title caps

Depends if you want to go by Gregg Reference Manual or Chicago Manual of Style

For Titles-- Gregg: E-Mail Chacago: E-mail
Beginning of sentence-- E-mail
