What is the Letter ad format?

Think of an actual letter — handwritten or neatly typed — where someone's talking directly to you about why they started the company or what they believe. It creates this quiet, intimate feeling that doesn't scream "ad," so people drop their guard and actually read. It works best when you have something real to say about your mission or values, not when you're just pushing a product feature.
