I used to get the notification email, but it's not working now

They are not working and they're not going to my spam folder either. I used to get them, but I'm not now. I wonder if they got the auto reply message.  Also- when I went into my account it said that I was out of storage, so I upgraded my account.  Does that mean that there were submissions that I did not receive in the meantime?  Why didn't I get an email saying that I was out of storage space?
