These estimates are conservative. Most operators see their first responses 90-120 days after the first mail batch lands. The math improves as the list quality compounds.

Where the defaults come from

  • $3.27 per handwritten letter — production + envelope + first-class postage. The premium tier of direct mail.
  • $0.86 per postcard — full-color, double-sided, NCOA-validated, first-class postage.
  • $2,000 average move value — residential local + small long-distance mix. Operators serving the premium tier or long-haul see higher AOV.
  • 9% response on handwritten letters — conservative against ANA/DMA's published direct-mail benchmarks for high-personalization sends.
  • 2.5% response on postcards — slightly under DMA's published prospect-list benchmark, in keeping with the conservative posture.
  • 40% close rate on responses — pro.movingletters.ai's published industry-average benchmark.
  • $399/mo ListingPro — the new all-you-can-eat flagship covering a 50-mile radius, owner + realtor contacts, unlimited zips and listings.

How to use the number

The projection at the bottom is a planning tool, not a guarantee. Run the calculator twice: once at 100% handwritten letters to see the upper-bound revenue, once at 100% postcards to see the lower-bound cost. The right mix for your shop sits between those two extremes.

Most operators we work with end up landing on roughly 20% handwritten / 50% new-listing postcards / 30% under-contract postcards. The letter is the trust play. The postcards are the volume play. The combination compounds.

When you're ready

If the projection at the bottom is the number you need to hit and the math says you can hit it, apply for access. We work with one mover per market, so the metro you're in matters. If the math doesn't pencil for you, the calculator is still yours to keep — pull it up next quarter when your volume changes.
