On your numbers, digital is cheaper per customer ($120 vs. $260). Mail would need a response rate above 0.65% just to break even.

And the town-hall point: every piece you send adds density to a route the carrier walks six days a week anyway — which is what keeps the stamp from climbing again.

How this is calculated
  • Responses = pieces × response rate.
  • Customers = responses × share that buy.
  • Campaign cost = pieces × all-in cost per piece.
  • Revenue = customers × average customer value.
  • Digital comparison = same number of customers × your digital cost per customer.
  • Break-even rate = cost per piece ÷ (share that buy × customer value).
  • No industry benchmarks are assumed. Results ignore repeat purchases, timing, and brand effects.
