Delivery Confirmation is great, but does not prove that the person received their cards. I have a couple of friends that work for the post office and each one states that the one true way to prove delivery to the intended person is by obtaining a signature.

A fellow trader on another site had conducted a trade. The card he was to receive had delivery confirmation and it actually stated online that the card was delivered with the time and everything. However, the person did not have the card in hand. As it turns out, the card was delivered to an older woman about two blocks away from his house. That woman was nice enough to deliver it to the proper address. And yes, the address on the envelope was correct for the intended person.

Human error still comes into play with delivery confirmation. Though a great tool, it is not fool proof.
