Send less mail,to the right driveways,and call behind every piece.

It can, but only your own numbers can prove it for your store. Mail has its clearest job when it reaches people who already know you, such as sold and service customers, and its hardest job when it goes to strangers with a generic sale message. Test it the way you would test any channel: one list, one offer, one drop, then decide on what it booked and sold rather than on how busy the phones felt that week.

There is no benchmark worth planning around. Published figures vary widely and are hard to verify, and a response rate counts calls and visits that never became appointments. Set your own baseline instead: shown appointments per 1,000 pieces for each list, compared with a holdout group that got nothing. A good result is one that beats your last drop and costs less per shown appointment than your other sources of buyers.

Postage is the easiest piece to look up. When we checked the USPS Every Door Direct Mail page on 8 October 2026, it listed EDDM Retail flats at $0.26 per piece, and postal prices change. Printing, design, any rented list and your team's calling time are quoted separately and vary by vendor and format. Add them all up for the drop and divide by shown appointments. That number tells you more than any price per piece.

Pick the format by how private the message is. A postcard can be read without being opened, which suits a service special or a Saturday appraisal on the conquest routes. Anything that names a customer's own vehicle, loan or payoff belongs in a sealed letter, because a postcard shows it to everyone who handles the mail. Whichever you choose, print one offer, one expiration date, and only that list's tracking number and landing address.

Every Door Direct Mail is a USPS service that delivers a piece addressed to 'Postal Customer' to every address on the carrier routes you pick, so no mailing list is needed. USPS lets you filter routes by Census age, income and household size (checked 8 October 2026). It is worth testing on the routes nearest the lot with a concrete offer, like a Saturday appraisal, and judging it against your equity and service drops, because nobody on those routes asked to hear from you.

A 'pre-approved' piece sent to people picked because their credit reports met a lender's criteria is a prescreened offer, and the Fair Credit Reporting Act sets specific rules for it. It must be a firm offer of credit, and it must carry a short and a long opt-out notice in the required type size and placement (15 U.S.C. 1681a(l), 15 U.S.C. 1681m(d) and 12 CFR 1022.54, checked 8 October 2026). Whether one mailer meets them depends on how the list was built and who makes the offer, so the lender and your attorney should approve it before it prints.

We cannot speak for any particular piece, but regulators have acted on this tactic. In a 2014 sweep of auto dealer ads, the FTC alleged that a Michigan dealer's prize mailers told people they had won when they had not (FTC press release, checked 8 October 2026). If you mail a game piece, print the real prizes and terms on it, never imply that every recipient is a winner, and have counsel read it before it prints.

Print a tracking number and a landing address that appear on that one drop and nowhere else, and tag every call and form fill in the CRM with the list it came from. Then, after a window you set, for example 45 days, match the mail file against DMS sales by name and address. Compare the result with the unmailed holdout, because some of those buyers would have come in anyway.
