No doubt, Dre! That's the funny part! I send out about 120,000 direct mailers a month and I don't control my lists. I'm waiting for one of my companies to send the other a postcard! I will laugh my ass off it that happenn!
Company registration is a public record so anyone can build a list just pulling from the public records of newly registered companies.
http://www.infousa.com/ is a big one that we pull lists from. We can put in criteria like "New Home Owner" and it will pull up a list of everyone who just bought a new home in the last month. I love them but then again, I hate them fuckers.
