Query: Don't get on his email list

I was unaware of John Zachman until recently, when myself and everyone in my company began receiving daily emails from his minions, encouraging us to become "Zachman Certified". Since out spam filters quickly caught all of these emails, I have to assume that thousands of others have been receiving the same unsolicited emails too and marking them as spam. I understand the concept of aggressive marketing, but it always forces me to wonder the value of any proposition that has to be rammed down your throat. Maybe becoming "Zachman Certified" would be a life changing event, but I really do wish they'd lose my email address.
