Don't know if it's the same in the US, but up here bulk mailers get a greatly discounted rate if they send out more than, say, 5,000 pieces in a mailing. I imagine mass printings have similar discounts.

So, it may actually cost less money to bombard 5,500 people, even if 2,000 of them are "dead", than to cull the list and send just to the "active" 3,500.
