Notifications to my email has stopped

[sttgthar0]

I always have 5 or 6 searches saved and sent to notify me via email when one comes up. Without notice they all have stopped. I tried to add new ones and remove old ones but still I don't receive any at all. Anyone else had that happen to them. If so did you find a cure. Thank you.

Have you tried removing the option to send you messages, and then selecting that option again?
