SMS and Text-Message Marketing Compliance for Law Firms

Texting is one of the highest-response channels a personal injury firm has, but it is also one of the most regulated, so you have to earn the right to send before you press send. Text messages get read within minutes, which is exactly why they help you respond to leads fast. That same reach is why federal law, carrier rules, and bar advertising rules all pay close attention to how firms use it. This guide walks through what actually keeps your texting clean.

First, the honest disclaimer: this is general information, not legal advice. Text-message law changes, carrier rules change, and your state bar has its own opinions. Before you launch anything, run your plan past qualified counsel and your carrier or platform. Treat everything below as a starting checklist, not a green light.

Why texting is powerful and why that scares regulators

People open texts. Open rates dwarf email, and replies come back in minutes instead of days. For an injured person weighing whether to call you back, a short, human text can be the nudge that keeps them in your pipeline instead of a competitor’s.

That power is exactly the problem from a regulator’s view. Because texts are so effective and so cheap to blast, they attract abuse. So the rules that govern texting are strict, layered, and enforced by more than one party at once:

• The TCPA and related federal rules govern consent for automated and marketing texts. Start with our parent guide on TCPA compliance for personal injury lead generation.
• Wireless carriers enforce their own rules through the A2P 10DLC system, and they block traffic that does not follow them.
• Your state bar governs attorney advertising and solicitation, which can apply to marketing texts. See bar advertising rules for personal injury lawyers.

You can satisfy one layer and still get shut down by another. That is why texting deserves its own plan, not a bolt-on to your email.

Consent basics: get it in writing, keep it specific

Consent is the foundation. The core idea is simple: before you text someone for marketing, you generally need their prior express written consent to receive texts at that number, and that consent should not be buried or forced.

A few plain principles:

• Say what they are agreeing to. The person should clearly see that by giving their number they agree to receive texts, roughly how often, that message and data rates may apply, and how to opt out.
• Do not make consent a condition of service. Marketing consent should be optional, not something they must accept to get a consultation.
• Keep consent tied to the number. Consent is for the specific phone number the person gave you, for the purpose they agreed to.

Your intake and lead forms are where this lives or dies. We cover the exact language and setup in personal injury lead form TCPA consent. If your form does not capture clean, logged consent, no amount of careful sending downstream will save you.

Transactional and one-to-one texts versus marketing campaigns

Not every text is a marketing text, and the difference matters. Think of it in two buckets.

One-to-one and transactional texts are the human, expected messages tied to a relationship or a request the person already made:

• A staffer texting a signed client back about their case.
• A reply to someone who just texted you first.
• An appointment reminder for a consult they booked.

Marketing and automated campaigns are the ones sent to promote your services, often to many people, often on autopilot:

• A blast to old leads saying you have space for new cases.
• Automated drip sequences that fire on a schedule.
• Any promotional offer sent from software rather than typed by a person.

The stricter consent and disclosure rules generally hit the second bucket hardest. But here is the trap: many firms think a friendly automated follow-up is transactional when a regulator would call it marketing. When in doubt, treat it as marketing and get consent. If you are running follow-up sequences at all, read should my law firm use email and text follow-up to see where the line usually sits.

A2P 10DLC registration in plain English

Here is the part that surprises most firm owners. Even with perfect consent, carriers can block your texts if your numbers are not registered.

A2P 10DLC stands for Application-to-Person messaging over standard 10-digit long codes, which is the ordinary local phone number your software sends from. Carriers built the 10DLC system to know who is sending business texts and why. If you send business or marketing texts from an unregistered number, carriers increasingly filter, throttle, or block them outright. Your messages may simply never arrive, and you often will not get an error.

Registration has two basic layers:

• Brand registration. You identify your firm as the legal entity behind the messages, usually with your business name and tax ID. This is the carriers vetting who you are.
• Campaign registration. You describe what you will send: the use case, sample messages, and how people opt in and opt out. This is the carriers vetting why you are texting.

A few plain-English truths about this process:

• Your texting platform runs the registration, but you supply the facts. Sloppy or vague campaign descriptions get rejected. Describe your real use case honestly.
• Unregistered blasts are the classic failure. A firm buys a number, imports a list, and blasts it. Carriers see unregistered high-volume traffic and block it. The firm assumes nobody replied, when in truth few messages landed.
• Registration is not a substitute for consent. It is a separate carrier requirement stacked on top of your legal obligations, not a replacement for them.

If you use a CRM or intake platform to send texts, confirm the 10DLC status before you rely on it. Our guides on whether personal injury lawyers need a CRM and on choosing an intake service both touch on the plumbing that makes this work.

Quiet hours, frequency, and clear opt-out

Even registered, consented texts can cross the line if you send at the wrong time or too often.

• Quiet hours. Sending late at night or early morning is a common way to generate complaints and violations. Many firms follow a conservative window, roughly 8 a.m. to 9 p.m. in the recipient’s local time zone, and hold marketing messages outside it. Confirm the specifics for your situation with counsel.
• Frequency. Match what you disclosed at opt-in. If your form said occasional messages, do not send daily. Over-texting drives opt-outs and complaints faster than almost anything.
• Clear opt-out. Every marketing program must let people stop easily. Honor STOP, UNSUBSCRIBE, and similar replies immediately and automatically, then send one confirmation and go silent. Do not argue, do not send a win-back to someone who just opted out.

If someone texts STOP and your system texts them again, you have turned one annoyed lead into a complaint. Opt-out handling is not optional plumbing.

Keeping records so you can prove it

When a complaint or dispute lands, the firm that can show its work wins. Keep records that let you reconstruct any message.

• Consent logs. Store what the person agreed to, when, from what form, and the exact language they saw.
• Message history. Keep a record of what you sent, to which number, and when.
• Opt-out records. Log every STOP and the moment you honored it.

Good software does most of this automatically. If you are stitching together a phone, a spreadsheet, and a memory, you have no defense. Tie this into your call tracking and intake records so the whole conversation lives in one place.

The do and do-not checklist

Do:

• Get clear, written consent before marketing texts, and log it.
• Register your numbers and campaigns under A2P 10DLC before sending.
• Keep one-to-one client texting separate from marketing blasts.
• Respect quiet hours and the frequency you promised.
• Honor STOP instantly and keep proof.

Do not:

• Buy a list and blast it. That fails on consent and 10DLC at once.
• Assume an automated follow-up is transactional. When unsure, treat it as marketing.
• Text someone who opted out, ever.
• Rely on registration to cover your consent obligations.
• Launch without running your plan past qualified counsel.
