The idea that marketing emails = "you don't want them" is fairly popular in some crowds, but it's contradicted by the tremendous business success of using marketing emails. The reality is that most people want and use marketing emails.

For example, I'm signed up for marketing emails from several airlines and these routinely save me money when booking vacations. Cheap airline tickets are a limited resource, so real-time notification of new availability has financial value to me.

Same with end-of-season sales for clothing I like. One company gives email recipients 1-2 days to shop before the sale is posted publicly on the website and social media.

It also ignores the tremendous popularity of email newsletters, which employ HTML formatting to improve the user experience, exactly the same way content websites do. In fact HTML email newsletters are often better than websites, because email clients don't execute javascript. The advertising is far less intrusive.

I know advertising is effective, it IS manipulating me. That's WHY I don't want it. "I don't want them" is not contradicted by the success of marketing, it's reinforced by the success of marketing.
