Law Firm Newsletter: Who Gets It and What to Count

A law firm newsletter should go to current and former clients, referral sources and people who asked for it. Send it to a clean list, and follow CAN-SPAM and your bar's ad rules. Judge it by replies, referrals and signed matters named in intake, not by the open-rate number a sending platform reports.

Quick answer

Build the list from three groups: current and former clients, referral sources with an ongoing relationship, and anyone who asked to join. Keep every issue truthful and give every recipient a working way to leave. Skip the open-rate column; Apple's privacy feature can inflate it for any reader who turned the feature on. Count replies, clicks on a link tagged for that issue, and what intake records when it asks how the person heard about the firm, then match any signed matter back to the newsletter before calling it a source of business.

Who belongs on the list, and what changes by group?

A firm's list usually has three kinds of names on it, and the rule that applies depends on which one a person is.

Does sending it make the message commercial email?

The FTC's compliance guide for the CAN-SPAM Act says what matters is "the 'primary purpose' of the message." It sorts content into three kinds: commercial, transactional or relationship (which facilitates or updates a transaction the reader already agreed to), and "other," which is neither. When a message mixes commercial content with "other" content, it counts as commercial if a reader of the subject line, or of the body, would likely conclude it mainly advertises, judged by where the promotional part sits, how much of the message it takes and how color, graphics and type size set it off (FTC, checked 2026-10-05). The same guide says "the law makes no exception for business-to-business email," naming a message "to former customers announcing a new product line" as an example that must comply.

Once a newsletter counts as commercial, every send needs accurate "From" and routing information identifying the firm, a subject line that is not deceptive, a clear disclosure that the message is an ad, a valid physical postal address, and an opt-out that the firm must honor within 10 business days, kept working for at least 30 days after the message goes out. The guide lists penalties of up to $53,088 for each email that violates the law, a per-message figure, not a per-campaign one.

Does your state bar count it as attorney advertising?

It depends on who is reading it, and it depends on the state. New York amended its advertising rules effective June 1, 2026, and a New York State Bar Association article on the change says the old Rule 7.1(f) requirement to label advertisements "Attorney Advertising" has been eliminated (NYSBA, checked 2026-10-05). The current Rule 7.1 bars a false or misleading communication and requires the name and contact information of at least one lawyer or firm responsible for its content (NYSBA, checked 2026-10-05). Its first comment says the rule governs communications "to existing clients and to other lawyers," so a clients-only newsletter still has to meet it, and a checklist written before June 2026 may still list the old label.

Florida still asks for a label on some email. Under Rule 4-7.18(b)(2)(B), a written communication sent to a prospective client to obtain professional employment must, when it goes by email, have a subject line that begins "with the word 'Advertisement'," with a matching mark on any attachment (The Florida Bar, checked 2026-10-05). Rule 4-7.18(b)(3) then says the (b)(2) requirements, which also include a written statement of the lawyer's background, training and experience, "do not apply to communications between lawyers, between lawyers and their own current and former clients, or between lawyers and their own family members, or to communications by the lawyer at a prospective client's request." The Bar's handbook adds that its rules for unsolicited email cover messages "sent to prospective clients or referral sources," and a CPA or financial advisor is not on that exemption list, so ask the Florida Bar how it treats a list that mixes groups.

Every state bar sets its own version of these rules. I am not a lawyer and this is not legal advice, so read your own state bar's current text before copying either example above.

When does a newsletter turn into soliciting one person?

New York's and the ABA's solicitation rules ban live, person-to-person contact, not a written mailing; Florida's extra rules for written messages are covered above. The comment to New York's Rule 7.3, amended on the same 2026 date, describes that contact as "in-person, face-to-face, live telephone, and other real-time visual or auditory person-to-person communications, where the person is subject to a direct personal encounter without time for reflection," and adds that it "does not include text messages, or other written communications that recipients may easily disregard" (NYSBA, checked 2026-10-05). The ABA's own comment to its model version of the rule uses almost the same words for live contact, excluding chat rooms and text messages from the restriction (ABA, checked 2026-10-05). New York's comment names email as one alternative to live contact, though its Rule 7.3(c)(1) still bars soliciting anyone who has said they do not want to be solicited.

Referral sources also get some room under the in-person rules. Florida's comment to Rule 4-7.18 walks through working relationships that count as a "prior professional relationship," including a lawyer who is legal advisor to a charitable board, a lawyer with a direct, continuing relationship with another professional in a trade organization tied to both practices, and a doctor who serves as the lawyer's expert witness. The comment exempts those persons from the general ban on direct, in-person solicitation; it does not lift the written-communication requirements, which the handbook applies to referral sources. For the broader differences between states on required labels, filing and claims, see attorney advertising rules.

Can a client's matter appear in an issue?

Only with the client's consent or with the details stripped out, under the ABA's model confidentiality rule. Rule 1.6(a) reads: "a lawyer shall not reveal information relating to the representation of a client unless the client gives informed consent, the disclosure is impliedly authorized in order to carry out the representation or the disclosure is permitted by paragraph (b)" (ABA, checked 2026-10-05). Paragraph (b)'s exceptions cover situations such as preventing death or serious harm, a client's crime or fraud, and the lawyer's own compliance or defense; marketing is not among them, and ABA Formal Opinion 480 adds that the duty covers "information contained in a public record" (ABA, checked 2026-10-05). So write about a matter only after asking the client, in writing, or strip every fact that could identify the matter or the person.

Firm news travels with none of that friction: a new partner, an office move, a practice area the firm added. The same consent question comes up on the firm's other unpaid channel; social media for lawyers covers what a post can say. Law firm marketing covers how a firm tracks where its cases come from once a channel like this one is running, and the same intake field that records a referral source should record "newsletter" when someone names it.

Why will the open-rate number mislead you?

Apple says remote content in an email can tell a sender "when and how many times you view it." With Protect Mail Activity selected, the setting behind Mail Privacy Protection, that content "is privately downloaded in the background when you receive a message (instead of when you view it)" (Apple, checked 2026-10-05). The download happens whether or not the person ever opens the message, so a platform that counts an open when that content loads can record opens nobody made.

The fix is not a better open-rate dashboard; it is reading something else. A reply, a forwarded issue, a click on a link that only this issue uses, and a new consult that names the newsletter all happen because a person engaged with the message, something a background download cannot fake.

What should you log each quarter instead?

Five numbers, pulled from three places. From the sending platform: replies and clicks on a link carrying a UTM tag, the short code appended to a URL that names the source and the specific send, so website analytics can credit a visit to that issue rather than to search or a bookmark. From intake: how many new contacts named the newsletter, or named a person who reads it, when asked how they heard about the firm. From case management: how many of those were signed, and the hours staff and attorneys put into writing, cleaning the list and sending.

Illustrative: the quarter below belongs to an invented four-lawyer family and consumer-protection firm; every figure in it is made up, and none comes from a client.

Hours per signed matter = hours spent ÷ matters signed: 9 ÷ 3 = 3 hours each. At this firm's own figure for an hour of staff and attorney time, say $150, that is 3 × $150 = $450 in time spent for each signed matter the newsletter can be tied to. Measure that against what a signed matter of that kind leaves the firm once the work is done. A single quarter this size is thin; three more quarters of the same sheet before raising or cutting the time spent is a reasonable wait.

Before handing the sending platform to anyone outside the firm, ask what it will and will not show:

• Does the report separate replies and link clicks from the background-opened count, or only show one blended number?
• Will every link in an issue carry its own UTM tag, or does that have to be added by hand each time?
• Where does the opt-out list live, and who can add a name to it inside the 10-business-day window CAN-SPAM requires?
• Who checked this issue's subject line and footer against the firm's current state bar rule, and when?

A newsletter earns its place on the firm's task list once a few quarters of that sheet show matters on the signed row, not before.
