Is it e-mail or email?
You can vote at this poll by IntelliReach Corp.
“I dare say the hyphen in e-mail will wither away, but I vote for it. You wouldn’t write “Abomb,” for “A-bomb,” or “opositive” for “O-positive,” or “Xray” (which looks like the name of a science fiction villain), or “fstop.” And “ecommerce” is not good. It looks like it should be pronounced “ecko-merce.” And “echecking,” “efiling,” “evoting”? No. No. No. New words should be formed in such a way that they reflect as closely as possible how they are pronounced.”—Roy Blount Jr., Humorist/writer/novelistWell said, Roy. I'm with you.
