Mine stopped too
Three of us have mypoints accnts. They all stopped receiving mail a couple of months ago. They are not going to a spam folder. I just can't figure out what the problem is. We haven't done anything that mypoints forbids. I even did that update thing several weeks back that was good for 60 points.
I even sent them a couple of emails asking what's up. No reply! I sure miss the fast and easy Hilton points!
