I also use a Unique-per-service email address with Paypal, and I noticed that Paypal actually passes on that email address to the retailer when I pay with Paypal.
I receive order confirmation emails (from those retailers) and quite a few unwanted newsletters to my unique paypal address now.
I have no idea what Paypal is trying to achieve by passing on this fairly personal piece of data. I always have to enter a separate email address with the retailer anyway, and because of this scheme, those two of course never match.
