I wrote to someone at Dictionary.com a while ago with the same question. It took a while to get a reply, but they
said it should be e-mail since it means electronic-mail and is shortened to e-mail. I’m not saying you are wrong at all, but
I’m still curious about it. If it is email wouldn’t that be spelled electronicmail, all one word, no hyphen? That makes less
sense to me. Isn’t e-mail/email just an acronym for electronic mail? You should be able to replace them with each other,
shouldn’t you?
Also what about these examples:
“I’m going to send you an e-mail/email” — “I’m going to send you an mail” (as in snail mail)
“I’m going to send you e-mail/email” — “I’m going to send you mail”
“I’m going to send you a letter” — “I’m going to send you letter”
Obviously you can’t just replace these all with “electronic mail”, but why not? Aren’t they all forms of mail, electronic or not?
Electronic mail is used far more often now than postal mail. I guess it just proves that our language is changing all the time.
Any input will be welcome.
p.s.
If I send e-mail/email to someone of the fairer sex, would I be sending her fe-mail or femail?
