A birthday is the one piece of customer data with a built-in deadline. A brand that asks for it is making a promise: we will remember, and we will do something about it. The brands in this post kept that promise, and the way they did it is worth copying.
We tried to join more than 300 quick service and fast casual email, loyalty, and lifecycle programs by hand, using one identity and one inbox. More than a dozen brands sent a birthday email, and the best of them treated it as a small campaign rather than a single send.
