About thirty years ago I too heard voices. I would be sleeping and clearly hear "You have mail". Cleaning my home office I'd hear "You have mail". Putting tile in the bathroom off the office "You have mail". Late nineties it just stopped. The puzzling part is that on many occasions I did not have mail. I'd go to the mailbox, and no mail. I asked the mailman about this and he just shook his head and walked away.

You probably had AOL too.

I remember the 90s. “You got mail” was heard quite often in my house. I remember one time, though, I was home alone and I heard a door shut. I finally figured out what it was, but it scared me at first. It was the email account on the computer.
