Attorney Direct Mail: Rules, Labels and Waiting Periods

Attorney direct mail is a letter a firm sends to a named person on a list, the targeted end of law firm advertising and the one channel where the envelope itself carries rules.

The Model Rule comments treat communications aimed at the general public, like billboards and TV, as not solicitation; a letter addressed to one person is what those rules were written for.

More Booked Cases does not run direct mail programs, so this page is rules and response mechanics, not a pitch.

Can a law firm use direct mail?

The starting case is Shapero v. Kentucky Bar Ass'n, 486 U.S. 466 (1988): the Supreme Court held that a state may not categorically ban truthful, non-deceptive letters to potential clients known to face particular legal problems.

ABA Model Rule 7.3(a), amended in August 2018, defines solicitation as a communication initiated by or for a lawyer, directed to a specific person the lawyer knows or should know needs legal services in a particular matter and offering to provide them.

Rule 7.3(c) reaches every channel, mail included: it bars soliciting anyone who has said stop and any solicitation involving coercion, duress or harassment, and Comment [6] says live contact with especially vulnerable people (the elderly, non-English speakers, the disabled) is ordinarily not appropriate.

Model Rules bind no one until a state adopts them; what states add is the timing, content and labeling below, covered rule by rule at ABA Model Rule 7.3 and solicitation.

The envelope rules: the advertising material label and state markings

In 2018 the ABA deleted the Model Rule requirement that targeted written solicitations carry an "advertising material" label, finding no evidence unmarked mail harmed consumers; the Model Rule binds no state, and many keep their own labeling rules.

The state versions regulate the envelope; Texas's Rule 7.03 (effective July 1, 2021) requires targeted written solicitations to be marked "ADVERTISEMENT," presumed proper when envelope and first page carry it in 3/8-inch bold capitals (Comment 10).

One New Jersey notice reads: "Before making your choice of attorney, you should give this matter careful thought. The selection of an attorney is an important decision."

Waiting periods: Went For It, Florida and Texas

Florida Bar v. Went For It, Inc., 515 U.S. 618 (1995), upheld Florida rules barring personal injury lawyers from mailing targeted direct mail to accident or disaster victims and their relatives for 30 days; the holding upheld Florida's rule and did not give other states a waiting period.

Florida's current Rule 4-7.18(a), as of October 1, 2026, bars a written solicitation about personal injury, wrongful death or an accident or disaster unless the event happened more than 30 days before the mailing, counted to the mailing itself.

Texas reaches the same window by statute: Penal Code §38.12(d), current text as of 2026, makes it an offense to send an unsolicited communication about personal injury, wrongful death or an accident or disaster "before the 31st day" after the event, a first offense a Class A misdemeanor.

Mail or email: CAN-SPAM and the letter-only state

Email adds a federal layer: the FTC's CAN-SPAM guide says the law applies to all commercial email, business-to-business included, and requires accurate headers, non-deceptive subject lines, identification as an ad, a valid postal address and a clear opt-out honored within 10 business days by a mechanism that works for at least 30 days.

The same guide, accessed October 3, 2026, puts penalties at up to $53,088 per violating email, yearly adjusted.

New Jersey stacks a channel rule on top: RPC 7.3(b)(5), read literally, allows specific-event solicitation only by regular-mail letter.

One mailed notice belongs to the court: for a Rule 23(b)(3) class, the court must direct "the best notice that is practicable," including individual notice to identifiable members by U.S. mail, electronic means or other appropriate means.

That court-ordered notice differs from a firm's own outreach, which bar advertising rules still govern.

Lawyer direct mail marketing: after the piece lands

A targeted letter asks the reader to call, scan or type a web address; the response is a call, form fill or email, and intake decides what it produces.

In Clio's 2019 secret-shopper study, a third party emailed 1,000 randomly selected US law firms and 60% never responded; of the replies, only 29% were timely, clear, answered a question and gave cost or consultation information, and a 2024 rerun found 33% responding to email (different sample, directional).

Clio's 2019 survey of 2,000 US consumers found 79% expected a reply to a phone message or email within 24 hours.

These are email tests in five practice areas (family, criminal, bankruptcy, employment, business), not measurements of a mailing, so the lesson is about intake.

More Booked Cases does not sell direct mail; the work is CRO, local SEO and managed Meta ads, judged on consultations booked and cases signed.

For the rest of a channel plan, the estate planning marketing guide covers a practice where readers plan ahead rather than react.

Checks before a targeted mailing

Rules change and each state's version differs, so confirm any mail piece with your state bar's ethics counsel or an ethics lawyer.
