But people still speak with it in there, great quote btw:
'I don't even have an e-mail address. I have reached an age where my main purpose is not to receive messages.' --- Umberto Eco, quoted in the New Yorker
By that, do you mean people pronounce it e-mail, with a long e? Because we have words like emu, evoke, even, elongate, and others. We don't necessarily need a dash to pronounce a long e.
The New Yorker tends to hang on to hyphens far longer than the rest of the printed world. Those and diaereses. You'll still see things like "teen-ager" and "coördinate" among their pages. It's just part of their style.
