Before you can improve your return, you need to measure it correctly. Here are the core metrics. “Campaign costs: Total everything: design, copywriting, printing, postage, list rental or acquisition, data processing, and any technology fees.” Cost per piece (CPP): Divide total campaign costs by the number of pieces mailed. CPP varies significantly by format, paper stock, mailing class, and personalization complexity. A standard postcard might cost $0.40 to $0.65 per piece, while a personalized letter package could run $1.00 to $1.50.
