Donald Knuth prefers "email" without the hyphen [1], according to his webpage which dates back to 1997 or earlier [2]: > A note on email versus e-mail > Newly coined nonce words of English are often spelled with a hyphen, but the hyphen disappears when the words become widely used. For example, people used to write “non-zero” and “soft-ware” instead of “nonzero” and “software”; the same trend has occurred for hundreds of other words. Thus it's high time for everybody to stop using the archaic spelling “e-mail”. Think of how many keystrokes you will save in your lifetime if you stop now! The form “email” has been well established in England for several years, so I am amazed to see Americans being overly conservative in this regard. (Of course, “email” has been a familiar word in France, Germany, and the Netherlands much longer than in England --- but for an entirely different reason.)
