Since I was the person who said that, What I said, very specifically, is that they aren't screened for advertising. Which is true. As another user mentions, there's basically no mail service that doesn't "screen" your email. Spam classification is a form of screening. The data used to show you upcoming flights and purchase info isn't used to advertise for you, its used to show (hopefully) useful reminders.
