The emailer I've got at home certainly does involve paying for the email checks, and I was under the impression that the E3 was the same, except with a more frequent minimum period for calling home.
According to the manual, the emailer, by default, attempts to do a send-and-receive daily, but you ought to be able to change this. It *also* calls a freephone number in the middle of the night to update its adverts; you can't turn that off, and if you prevent it from doing this, it'll stop working. And then as a third thing there's the caller-ID trick tells it whether there's email waiting, which doesn't cost anything.
