emscli allows "ini", "rep", and "ret" as notification options. "rep"
repeatedly triggers notification while the condition is met. "ret" triggers
once when the condition changes from "met" to "non-met".
Unfortunately "ini" is not the opposite of "ret": It triggers notification
when the condition changed from non-met to met, but also triggers notification
when the first poll happens.

It's documented (vaguely) that way, but I really think the last two cases
should be handled separately. With the current state if you configure EMail
notification for a dozen of events, you'll receive a lot of messages, all with
the same subject (Oh, yes, a more reasonable subject on email notifications
would be great).

Are there chances that things will improve in the coming releases?
