Thanks for reaching out Bret. The issue I've found is it's much harder to monitor on an email NOT arriving, than one arriving with specific text. With the latter I can be as lazy as setting up a GMail fiter, with the former... I'd have to build my own reporting system that knows you'll email about 8-9am and if the email doesn't arrive, assume it's failed. That's a lot of overhead.

How to best monitor something doesn't happen (e.g. a scheduled, remote job) is something I've yet to solve.
