I get Private messages and get email notifications of them 2 or 3 days later, even though they've been read. I received an email notification of a private message this morning that I received, read and replied to 3 days ago. Also, there doesn't seem to be an order to the notifications, either. You'll get a notification sometimes, within 1 hour and other times, within several days.
