Direct mail prospecting rules: what the law requires

The federal floor

No federal law requires consent, an opt-in, or a do-not-mail registry for postal advertising mail. The Telephone Consumer Protection Act covers calls and texts. CAN-SPAM covers commercial email. Neither reaches a postcard or letter. See cold calling laws and the TCPA explained for the channels that do need consent.

That makes mail the one prospecting channel where a named list can be used with no consent step. It does not make mail unregulated. Five bodies of law reach it: USPS postal rules, the federal ban on mail that imitates the government, FTC deception law, the Fair Credit Reporting Act when the list comes from credit data, and state statutes aimed at foreclosure services. The sections below take them in that order. For the operating side, see direct mail prospecting, start to finish.

Is there a do-not-mail list?

There is no government one. The closest thing is DMAchoice, a mail preference service run by the ANA, an industry group. A consumer pays $8 online or $9 by mail, and the ANA says the fee keeps the preference on file for 10 years.

The ANA states that the service "is not a tool to effectuate rights under any specific law." Only companies that subscribe receive the suppression file. It does not stop transactional mail, prescreened credit offers, political mail, mail addressed to "current resident", mail from companies that do not subscribe, or mail from companies the person already deals with.

For a prospector, the practical read is simple. Subscribing and suppressing against DMAchoice is optional and cuts complaints. It is not a legal safe harbor, and skipping it is not a violation. Prescreened credit offers have a separate opt-out, covered below.

What the USPS requires

USPS rules attach to the postage you claim, not to who you mail. Three matter for prospecting lists.

• Move Update. Mail claiming presorted or automation First-Class prices, or any USPS Marketing Mail prices, must use addresses updated with an approved method within 95 days before mailing. Preapproved methods include Address Change Service, NCOALink, and ancillary service endorsements (except Forwarding Service Requested); First-Class mailers can also seek approval for alternative methods. The Domestic Mail Manual sections are DMM 602.5.0 for NCOALink and DMM 507.4.2 for Address Change Service.
• Nonmailable matter. Under 39 U.S.C. 3001, a piece that looks like a bill is nonmailable unless it carries a conspicuous notice that it is a solicitation and not a bill. A private solicitation that suggests federal approval, such as with a seal or agency name, needs a disclaimer on the face of the mailing and the envelope must say "THIS IS NOT A GOVERNMENT DOCUMENT" (3001(h)). A mailing that uses the word "census" must carry an accurate return address with the sender's name.
• Checks and sweepstakes. Under 3001(k), mail that resembles a check must state that it is not a negotiable instrument and has no cash value. Sweepstakes mail must say no purchase is necessary, give the rules and the sponsor, and may not say the recipient has won unless they have. Subsections (k) and (l) were added in 1999 by the Deceptive Mail Prevention and Enforcement Act (Pub. L. 106-168).
• Stop requests. Under 3001(l), anyone who sends mail covered by (h), (i), (j) or (k) must honor written requests to stop, made directly or through a state attorney general, and suppress that name and address for 5 years from the request. This is the one federal mail opt-out, and it reaches only these mail types.

A common investor mistake is the "official-looking" envelope or a fake check in a seller letter. Either can make the whole drop nonmailable.

What the FTC and the FCRA add

The FTC Act, Section 5 (15 U.S.C. 45(a)), declares unfair or deceptive acts or practices in commerce unlawful. Mail content is covered. A claim that a buyer will pay "full market value," a fake deadline, or a letter written to look like a legal notice are all deception questions, whatever the delivery channel. Keep the evidence for any claim you print.

The Fair Credit Reporting Act applies when the list is built from consumer credit data, which is called a prescreened list. A consumer reporting agency may furnish such a list only for a firm offer of credit or insurance, and the data is limited to name, address, a non-unique identifier used to verify identity, and information that does not reveal the consumer's history with a particular creditor (15 U.S.C. 1681b(c)). Consumers can opt out of prescreening; a system opt-out lasts five years, and a signed form lasts until revoked (1681b(e)). Each written solicitation needs a clear notice that the person may opt out, with the address and toll-free number of the notification system, and the user must keep the selection criteria for three years (1681m(d)). Credit-data lists cannot be repurposed for a general sales pitch.

Lists built from county assessor records, recorder filings and court notices are public-record lists. They do not fall under the prescreening rules. See data broker laws for the rules on how list data is sourced.

State rules that touch mail

States have no general mail-consent laws that this page found. The state rules that matter to real estate prospectors target foreclosure services. They govern the contract, not the postcard: the Texas and California sections below set notices and cancellation rights that must come before the owner signs. They still matter to a mailer, because a piece that offers foreclosure help is the start of that regulated relationship. The table also collects the federal rules in one place.

Rule	Source	What to do
Foreclosure consultant notice in 14-point bold before the contract is signed; cancellation right	Tex. Bus. & Com. Code 21.052	If you offer foreclosure help in Texas, give the notice before any signature
Written contract, "Notice Required by California Law" in 14-point bold, cancellation form with a 5-business-day window	Cal. Civ. Code 2945.3	Use the statutory contract and notice in California
Mortgage assistance relief ads need "IMPORTANT NOTICE" disclosures, including that you are not associated with the government	12 CFR 1015.4	Add the disclosure block to every piece that sells loan relief
Look-alike government mail needs disclaimers	39 U.S.C. 3001(h)	Do not use seals, agency names or "official notice" styling
Move Update within 95 days for discounted rates	USPS QSG 602a	Run NCOALink inside the 95-day window
Prescreen opt-out notice and 3-year records	15 U.S.C. 1681m(d)	Only for credit-data lists

Regulation O applies to providers of mortgage assistance relief services. If you buy houses and do not sell a relief service, check with counsel whether it reaches you. Texas and California are two examples, not a full survey. Check the foreclosure consultant and equity purchaser statutes for each state you mail. Our pre-foreclosure list page explains where that data comes from.

The single policy that clears all of it

1. Mail only to addresses from public records, owner files or your own customers. Never use a credit-data list for general marketing.
2. Run NCOALink inside 95 days of each drop.
3. Keep an internal suppression file with no expiry. Match every list to it. Also suppress against DMAchoice if you can.
4. Print your real company name and a working return address on every piece.
5. No seals, "notice" headers, invoice layouts, fake checks, or census language.
6. Support every claim with a record you keep.
7. Do not offer loan relief to distressed owners unless a lawyer has reviewed your state rules and Regulation O.
8. Keep copies of every mailer and the drop date for at least three years.

Penalty exposure

Postal penalties are per mailing. For a person who evades or ignores a USPS order under 39 U.S.C. 3005, or helps someone who does, 3012(a) allows up to $50,000 for each mailing of fewer than 50,000 pieces, $100,000 for 50,000 to 100,000 pieces, and an extra $10,000 for each further 10,000 pieces above 100,000, capped at $2,000,000. Section 3012(d) allows up to $10,000 for each mailing to an individual made in violation of the 3001(l) stop-request rule. The Postal Service can also subpoena records under 39 U.S.C. 3016.

The FTC can seek civil penalties of $53,088 per violation for a knowing violation of a trade regulation rule (15 U.S.C. 45(m)(1)(A); 16 CFR 1.98). That figure applies to penalties assessed after 01/17/2025. Penalties of that size attach to rule or order violations, so check which rule your pitch touches. Private suits, state attorney general actions and criminal charges under foreclosure statutes are separate. Compare telemarketing penalties, which are much larger for calls and texts.

What changed in the last 24 months

• 01/17/2025: the FTC's inflation-adjusted civil penalty amounts took effect, raising the Section 5(m)(1)(A) figure to $53,088 (16 CFR 1.98).
• 10/04/2026: USPS began a time-limited 2026 price change, effective through 01/17/2027, with Notice 123 marked final on 09/18/2026 on the Postal Explorer price page. Recheck your postage budget.
• No federal statute giving consumers a mail opt-out or consent right appears in the sources reviewed for this page. DMAchoice remains voluntary.

Questions people ask

Q01Is it legal to send unsolicited mail to a homeowner?

Yes. No federal statute requires prior consent for postal advertising mail, and none creates a government do-not-mail list. The limits are on content and on the address list: the piece must not mislead, and it must not imitate a government notice, bill or check.

Q02Do I have to honor a request to stop mailing someone?

For ordinary advertising mail, no federal law requires it. For sweepstakes, skill contests, facsimile checks and mail that suggests a government connection, 39 U.S.C. 3001(l) does: honor written stop requests and keep the name and address suppressed for 5 years. Either way, keep an internal suppression file and match every future list against it.

Q03Does the Move Update rule apply to every mailer?

It applies to mail claiming presorted or automation First-Class prices or USPS Marketing Mail prices. If you pay full single-piece postage you are outside it, but you still waste money mailing to old addresses. Most list vendors and print shops run the check for you.

Q04What is a firm offer of credit?

A firm offer is a credit or insurance offer that the consumer must receive if they meet the criteria used to select them. A prescreened list built from credit data may only be used for that, and each solicitation needs the opt-out notice.

Q05Can I mail homeowners in pre-foreclosure?

Yes, on a list made from public default and auction notices. The risk is in the pitch. A service that offers to help with loan relief falls under CFPB Regulation O, and some states require contract notices for foreclosure consultants or equity purchasers.
