I know of one regulator in USA (WSLCB) that sends critical and time sensitive notifications via email only. Has had delivery problems for at least five years and cannot see the flaw in their system.

Is the flaw on their side or your side?

		Varies. Some times their system doesn't get the message to their outgoing gateway, sometimes their gateway doesn't deliver (and it's a different agency that runs that, so support is hardly available), sometimes our provider (G) filters the messages. It's a mess all round. The core flaw is depending on email for this. In fact it used to be a real-time API and the agency regressed to this. And their own system doesn't recognize invalid or undeliverable messages so it can get lost easy.
