USMail.AI

Law firm notices? Mail clients in one upload.

By the USMail.ai team, more than 50 years of combined expertise in printing and mailing

Direct answer: Every client learns what is changing at your firm and what to do next, and we print and mail each letter you approve. You upload the letter and your client list, check the proof and the full price on screen, and approve. USMail.ai handles the printing, envelopes and postage, so nobody leaves the office.

Statutes checked October 29, 2026: client-notice duties for law firms come from your state's rules of professional conduct, ethics opinions and court rules, not one federal statute, so this page quotes none. Your state bar or ethics counsel decides what your letter must say. General information, not legal advice.

Which law firm letters does this cover?

Law firms mail clients at the moments that change the relationship. These pages cover the four we see most often:

  • Attorney leaving the firm: the letter that tells clients a lawyer is leaving and lets them choose who keeps their matter.
  • Law firm closing: the letter that tells every client the firm is closing and where their files go.
  • Disengagement letter: the letter that ends a representation, including a withdrawal from a matter.
  • Non-engagement letter: the letter that confirms you are not taking a prospective client's matter.

The firm also mails engagement letters, status updates, billing statements and demand letters. For a single demand, see how to send a demand letter online.

Why mail these letters instead of only emailing them?

Email is fast, but a paper letter leaves a clear record that the firm sent written notice to the address on file. Many firms send both: an email for speed and a mailed letter as the written copy. Clients who rarely check email, older clients and clients without a portal login still get the letter. Your state's rules and your own policies decide which channel a given notice needs, and your ethics counsel can confirm the method.

When should a letter go by Certified Mail?

Use Certified Mail when one client or prospective client must receive a single letter and you want a USPS record of mailing, such as a disengagement or non-engagement letter. Certified Mail is $1.15 plus the current USPS Certified Mail fee, which USPS publishes in Notice 123. We don't offer paper Return Receipt yet. You can read more on what Certified Mail costs. A letter to every client, such as a firm closing or a lawyer's departure, usually goes First-Class, because the same letter goes to a whole list.

How does mailing work on USMail.ai?

You upload. You approve. We produce. You upload the letter as a PDF or document, add your list, and check the proof on screen. You see the complete price before you approve, and nothing prints until a person on your staff says yes. From our own production floor: we print, envelope and hand each piece to USPS, and you see the proof and the full price before you approve. Every address comes from you. We check every address before mailing, and the AI never suggests or adds one.

If plans change, you can unapprove an approved job before its mail date, and the money goes back on your meter balance, not your card. A meter balance is optional, and you can pay per mailing.

What does it cost?

Letters starting at $1.15, postage included. For a one-page, single-sided, black-and-white First-Class letter. You see the full price for the whole mailing before you approve. Certified letters cost more, and the exact amount shows before you approve. USMail.ai is an AI print-to-mail platform, not USPS.

How far ahead should the firm mail?

Mail as soon as the decision is made and the letter is approved by the responsible lawyer. Clients may need time to choose counsel, ask for files or meet a court date. USPS lists First-Class Mail at 1-5 business days on its First-Class Mail page, and USPS delivery times vary, so mail early enough. If a deadline is close, call or email the client first and treat the letter as the written follow-up copy.

What does USMail.ai not do?

We don't write your letter, choose which clients get it, give legal advice, or file anything with a court. We don't store your client files. Your conflicts checks, client list and trust accounting stay in your own systems. We print the letters you upload, exactly as you approved them, and hand them to USPS. Keep your own copy of every letter you send, along with the list it went to, since the job record is kept only until the expunge date you set.

Who at the firm usually sends these?

In a small firm it is often the office manager, a paralegal or the lawyer. Because the steps are the same for one letter or a long list, anyone on staff can prepare the job, and the responsible lawyer can review the proof before anyone approves it. That keeps the mailing off the front desk's plate on a busy week.

What do people ask about USMail.ai?

Can one upload go to every client on our list?

Yes, when every client gets the same letter. Upload the letter once, add your client list, check the proof and approve.

Can a single letter go by Certified Mail?

Yes. Certified Mail is $1.15 plus the current USPS Certified Mail fee. We don't offer paper Return Receipt yet.

Do you look up client addresses?

No. Every address comes from you, and the AI never suggests one. We check every address before mailing.

Is this legal advice?

No. This page is general information, not legal advice. Your state bar or ethics counsel decides what your letter must say.


When does my letter go to USPS?

By default, letters you approve before 10 p.m. CT are handed to USPS the next business day (Monday to Friday). USPS delivery times vary. USPS handles delivery from there. There are no contracts, subscriptions or setup fees.
