I do not see a transaction for this on the Google website. I do not see a transaction for this on my hosting company's website. I receive periodic snail mail offering a certain credit for Adwords if I spend a certain amount more for these "small business websites". I am not interested in using Google Adwords for these websites, nor will I ever be. These mailings are a waste of human time, paper, and fossil fuel in printing and delivery. How do I stop them?
Can you identify them before opening them? If so, there's always "refused-- return to sender". People tend to notice actions that require them to take some physical action in return. Outgoing mail is automated; incoming requires a human.
