I'm having the same problem. Ran a PQ last night about 7:20ish, never received it. Ran another this morning shortly after 7, same result. Gmail for me too. Didn't notice the notifies until I was reading this this morning, but I'm in on that one to.
Guess I'll load a few in manually and run with that for the day.
Just tried to run a PQ and send it to my yahoo mailbox and that one didn't work either, so obviously it doesn't matter where you send it, it's down.
