There’s the kind that no one can possibly like. The popups, popunders, high-pressure, track-your-private-data, scammy, spammy, interruptive, overpriced, overhyped, under-designed selfish nonsense that some people engage in.

And then there’s the kind that inspires us, delights us and brings us something we truly want.

We call them both marketing, but they couldn’t be more different.
