Marketing is often about doing what is right.
As in this beautiful, clear, honest page by Netflix introducing their free trial. They don’t fear you won’t like the service, and so they are straighforward about when the trial will end (even before you sign up). They will also let you know three days earlier, so that you can cancel if you want (they know you won’t). A credit card is still needed, but I am more likely to trust them with it with this kind of approach.
Marketing is (sometimes) also about doing what is funny.
That happens when you spot an opportunity in somebody mispronouncing your brand name at a conference. Instead of rectifying, you build numerous products with names very close to yours, and run campaigns to promote them. Everyone cheers you, and your brand is stronger than ever.
