Mastercard's CMO wanted to transform marketing to better measure effectiveness and serve commercial objectives. Marketing evolved from Marketing 1.0 focusing on emotions to Marketing 4.0 leveraging digital connections. Key campaigns included Priceless Cities providing exclusive experiences, Priceless Surprises creating special moments people were passionate about, and Priceless Causes supporting charitable causes through spending. The Priceless Engine platform delivered personalized offers through stories and data to drive engagement and transactions with merchants and banks. Evaluations found the campaigns increased spending, brand preference, and were effective in engaging customers, though competitors could potentially copy the approach.
