Got the same email! Wasn't sure what to make of it, as I open their emails and I also use the card. But, it's interesting reading about how we are being tracked with this type of techonology. Things that make you go hmmmmmmmmm.
I got this as well. Find it a bit funny that it wasn't a "use our card once every 12 months" or else, type of thing; but instead of "pay attention to our emails" or else, type of thing.
