The Christmas mailer exceeded all expectations and snowballed into a huge promotional piece for the agency. Recipients loved it (whether they got it instantly or had someone busting to explain it to them). More than that, they started talking about it and testing it on their friends. Before long, it was being picked up and discussed on radio stations and profiled in the national newspapers. Generating thousands of dollars worth of free publicity for the agency – and an unexpected ROI of over 1100% on agency costs.
