I DID get an email on 1MM. I did get a choice of token gifts at 2MM. I chose the Tumi computer bag. I doubt I will reach 3MM as started to travel on AA and Delta.
I think you should be fortunate to get an email thanking you instead of one asking for a donation! But then again you can say you made one at the mileage award counter.
We are not appreciated. We are over entitled.
