# Direct mail for teams selling to law firms

> Write to a managing partner about a public change at their firm, never a client matter. Sincerely researches, prints, and mails each letter you approve.

Cold email to a law firm has to clear spam controls and a crowded inbox. A partner can spot a mail merge in one line. Partners read arguments for a living and stop at the first claim you cannot support. A letter that works makes one point about the firm and backs it with a public fact. It is short enough to read between meetings and never mentions the firm's clients.

Sincerely builds each letter on a public fact about the firm, such as a lateral group joining or a new office. It researches the firm, writes, prints, and mails the letter, and sends the follow-ups. You read every draft, and nothing prints until you approve it.

This guide is for teams selling software and services to law firms, from solo practices to large partnerships. It does not cover corporate legal departments, which buy differently. For accounting firms and consultancies, see the [professional services guide](https://trysincerely.com/for/professional-services-agencies).

## A letter written for a managing partner

![Typed letter from Fieldnote, a legal billing company, to Rosa Alvarez, managing partner at Harlow and Pike, opening with: Your firm's new construction practice will inherit the billing complexity that comes with draw schedules and retainage.](https://trysincerely.com/samples/for-law-firms.webp "A fictional sample: a typed letter from a made-up billing software company to a law firm's managing partner, with the researched words underlined.")

What makes it work:

- It opens with the firm's new construction practice and the billing problem that practice brings.
- Its fact is public and about the firm: four construction partners joined the Denver office. No line mentions a client.
- It encloses a one-page summary, so the partner can judge the argument without a call.
- It asks for fifteen minutes and gives a direct phone number.

Use a typed letter for a researched argument. Save a handwritten note for a personal reason, such as thanks after a referral. The [handwritten mail guide](https://trysincerely.com/guides/handwritten-mail-b2b) explains when handwriting helps and when it reads as manufactured.

## Write to the partner who owns the decision

Firms assign authority by partnership role, so match the recipient to the decision.

- A managing partner or firm chair owns firm-wide strategy and margin.
- A practice group leader owns how one practice sells and delivers work.
- An executive director or COO owns operations, staffing, and vendors. In many firms this person runs the purchase.
- A CFO or pricing director owns rates, realization, and billing systems.
- A CIO, IT director, or innovation lead owns technology decisions at larger firms.

At a solo or small firm, the founding attorney is all of these people. One recipient is usually right. Write to two only when each owns a separate stake. The practice leader may feel the workflow pain while the executive director signs the contract.

## Write when the firm changes

A lateral move is the best reason to write. The arriving partner is rebuilding routines while the firm integrates them, and for a few months both expect change.

- A lateral partner or group joins, often bringing new clients and new systems.
- The firm opens an office or launches a practice group.
- The firm names a new class of partners, usually at the start of the year.
- The firm announces a merger or combination.
- Hiring concentrates in a practice area, a city, or an operations role.
- A conference conversation, referral, or bar association meeting creates a real follow-up.

## A partner will judge how you treat confidential information

Before anything else, a careful partner checks whether the vendor who wrote the letter understands privilege. Any line about client work suggests you might not, even when the matter is public. Leave out the verdict in the news, the closing on the firm's own site, and the case on the docket. A letter to Harlow and Pike can mention the new construction group. It should not name the developer that group just represented.

Write about the firm instead: its practices, offices, hiring, and the way it runs. If the piece says more than a plain invitation, put it in an envelope. Lawyers read that choice as a sign you know how their profession treats information.

Check the address as well. Large firms route mail by name, so add the practice group or floor when you know it. A solo attorney may practice from a home office or a shared suite. Their registered agent address may accept your letter and never pass it on. The [business address guide](https://trysincerely.com/guides/b2b-mailing-addresses) covers the method.

## Let Sincerely run the mail

Sincerely runs the mail channel for you. You approve every letter and take the calls.

- You write only to people who can say yes. Sincerely finds firms by practice area, size, office footprint, or a recent change. Then it adds the one or two people who own the decision.
- Every letter has a reason you can check. Each account stores its reason for writing with a date and a source.
- A person checks every uncertain or residential-looking address and confirms that the recipient works there before the letter prints.
- Nothing prints in words you have not approved. Sincerely writes each draft for one recipient. The account owner edits it and approves the exact design.
- A partner who asks to be left alone gets no new letters. Suppression and frequency caps apply across every campaign.
- After a referral or a rollout, you can send a gift with a personal note. The catalog has 46 items, and US prices start at $49. A person approves the recipient, gift, and exact price first, so you can check each order against the firm's own gift rules. The Send ledger records it beside the letters. See [gifts](https://trysincerely.com/gifts).

## See what works

Sincerely records replies and meetings against each firm. Most law firm programs reach a few dozen firms. Track replies, meetings, and engagements as separate outcomes, and describe what happened without presenting it as a controlled experiment. With a larger audience, Sincerely can hold out accounts and report lift with its interval. The [small-audience guide](https://trysincerely.com/guides/direct-mail-small-audiences) explains what a narrow program can and cannot prove.

## Start with the firms already in your CRM

Upload your target firms or sync Salesforce or HubSpot, and review the first drafts. Each letter spends prepaid credits, and you see how many before it goes out ([what each format costs](https://trysincerely.com/formats)). If nobody on your team has time, Sincerely's team can [run the program for you](https://trysincerely.com/managed-direct-mail). [Write to us](https://trysincerely.com/contact) to book a demo.
