Info Why don't I get all my email notifications

[MikeRWK]

I have notifications set to instant and no they arent going to my spam folder.It's like bl picks and chooses which ones to send and when I log in a few usually come at once, then if I don't logon for a few days they stop.

It seems to me like it's a way to save bandwidth or something? But maybe someone else can explain it or its a mystery.
