Short answer: cold texting is not flatly illegal, but most of it is done illegally. Under the federal TCPA, sending a marketing text to a mobile number without prior express written consent is unlawful and carries $500 to $1,500 in damages per message. Consent is the whole ballgame. There is no "we found your number publicly" exception, no "it was just one text" exception, and no opt-out-only workaround.
Everything below is the detail: what consent actually means, what the fines look like in practice, which states go further than federal law, and how real estate investors text motivated sellers without buying a lawsuit.
This is not legal advice. It is a plain-English overview so you know the questions to ask. TCPA and state texting laws change often. Talk to a telecom or TCPA attorney before you run cold outreach at scale.
Key takeaways
- Automated marketing texts to cells need prior express written consent under the TCPA.
- Penalties are $500 to $1,500 per message, and cases are often class actions.
- A2P 10DLC registration is required for deliverability, but it does not replace consent and opt-out rules.
- State laws matter: Texas SB 140, Florida's FTSA, and others add liability.
- The safe path is A2P registration, honored opt-outs, legal send windows, DNC scrubbing, and avoiding the strictest states.
Is cold texting illegal in the US?
It depends entirely on who you are texting, what you are texting them, and whether they agreed to hear from you. The same message can be perfectly legal to one recipient and a $1,500 liability to the next. Here is how the common scenarios actually break down.
| Scenario | Legal? | Why |
|---|---|---|
| Marketing text to a cell, no consent, sent by software | No | TCPA requires prior express written consent for autodialed marketing texts |
| Marketing text to a cell, written consent on file | Yes | Consent is the exception the statute is built around |
| Manually typed one-to-one text, no consent | Gray area | May fall outside the autodialer definition, but state laws and DNC rules still apply |
| Transactional or informational text (appointment, receipt) | Usually yes | Not telemarketing, so the written-consent standard does not attach |
| Cold B2B text to a published business line | Lower risk | TCPA is aimed at wireless consumer numbers, but many cell numbers are both |
| Any commercial text into Texas or Florida without consent | No | State mini-TCPAs add their own private right of action |
The line people miss: publicly available is not the same as consented. A phone number sitting in a county record, on a business listing, or returned by a skip trace carries no permission with it. Finding a number legally says nothing about whether you may text it.
What the TCPA actually says
The Telephone Consumer Protection Act (TCPA) governs calls and texts to consumers. For text messages, the core rule is this: if you use an autodialer to send a marketing message to a cell phone, you generally need prior express written consent from that person first. A motivated seller on a skip-traced list has not given you that consent, which is why "blast every number on the list" is a legal trap.
There is nuance. Some investors send messages manually, one at a time, arguing they are not using an autodialer as the law defines it. That reduces one category of risk but does not remove state-law exposure, carrier filtering, or Do Not Call issues. It is a gray area, not a green light.
Penalties are per message, not per campaign. At $500 to $1,500 each, a single blast of 1,000 non-compliant texts can mean $500,000 to $1.5 million in exposure. Plaintiffs' attorneys watch for exactly this.
What are the fines for cold texting?
TCPA damages are statutory, which means the plaintiff does not have to prove they were harmed. They only have to prove the message was sent. That is what makes this area of law so expensive.
| Violation | Damages per message | 1,000-message campaign |
|---|---|---|
| Negligent violation | $500 | $500,000 |
| Willful or knowing violation | Up to $1,500 | Up to $1,500,000 |
| State mini-TCPA claim (varies) | Often $500 to $1,500, stacked | Additional exposure on top of federal |
Two details make this worse than it first looks. First, damages are per message, not per recipient, so a five-touch follow-up sequence multiplies the exposure by five. Second, TCPA claims are routinely filed as class actions, and there is a well-established plaintiffs' bar that monitors for exactly this pattern. Most cases settle, but settlements on a mid-size list still land in six figures.
Cold texting vs cold calling: are the rules the same?
Mostly, but not entirely. Both are governed by the TCPA and both require you to scrub against the National Do Not Call Registry for marketing outreach. The differences that matter in practice:
- Consent standard. Texts to a cell are treated like calls to a cell, so autodialed marketing needs prior express written consent either way.
- Manual dialing. A human dialing numbers one at a time is a well-worn (if imperfect) path on the call side. The text equivalent is harder to run at any real volume.
- Carrier layer. Texting adds A2P 10DLC registration and carrier filtering. Calling has no direct equivalent, though spam labeling does similar damage.
- Evidence trail. Every text is a written record with a timestamp. Calls are harder to prove without a recording. Texts hand a plaintiff the exhibit.
If you are weighing the two channels on cost rather than risk, see the cost per deal by channel breakdown and the cold calling scripts guide.
A2P 10DLC for real estate texting: required, but not a legal shield
A2P 10DLC is the carrier system for registering application-to-person texting on standard 10-digit numbers. You register your business (brand) and your messaging use case (campaign), and carriers then allow your traffic at proper throughput. Skip it and your messages get filtered, throttled, or blocked, so your deliverability collapses.
Here is the part people get wrong: A2P registration is about deliverability, not legality. Being registered does not give you consent. You still have to follow TCPA consent rules, honor opt-outs, and respect state law. Think of A2P as the ticket to send at all, and TCPA compliance as the rules for what you are allowed to send.
State laws are the new minefield
Federal TCPA is the floor. Many states now stack their own "mini-TCPA" laws on top, often with private rights of action that make them easy to sue under.
| State law | What it does | Practical effect |
|---|---|---|
| Texas SB 140 | Expands the state telemarketing act to cover texts and strengthens consent requirements | Cold commercial texting in Texas is high risk without consent |
| Florida FTSA | State telephone solicitation act with strict consent and calling-window rules | Florida has driven many class actions; tread carefully |
| Oklahoma, Washington, others | Additional consent and disclosure requirements | Rules vary by state and change often |
The practical takeaway: a compliant operation does not text every state the same way. It avoids cold texting in the most aggressive states, or works only consented data there. Texas is the one worth reading in full, because it changed twice: see our breakdown of SB 140 and the November 2025 settlement.
Is cold texting motivated sellers legal?
Same rules, higher stakes. Real estate investors are texting homeowners at their personal cell numbers, pulled from skip-traced public records, with a commercial offer. That is squarely the fact pattern the TCPA was written for, and wholesalers have become a visible target for TCPA plaintiffs' firms over the last few years.
What makes it survivable is that the compliant version of this channel genuinely works. You are not choosing between "break the law" and "no leads." You are choosing between an unregistered blast and a registered, consent-aware, opt-out-honoring program that produces conversations at a fraction of PPC cost. The second one is slower to set up and considerably cheaper to run.
How to text motivated sellers the right way
If you are going to run SMS outreach, build these in from the first message, not after a complaint:
- Register A2P 10DLC for your brand and campaign so carriers deliver your messages.
- Scrub the Do Not Call registry and suppress known litigators and reassigned numbers.
- Identify yourself in the first message. No hiding who is texting.
- Honor STOP instantly and permanently. Every opt-out is suppressed across all numbers, right away.
- Stay inside legal send windows. No early-morning or late-night texts.
- Warm up numbers and keep volume sane so you look like a person, not a spam cannon.
- Respect state law. Avoid or gate the strictest states.
- Keep records of opt-outs and consent for years, not weeks.
For the message side of this, see our real estate text templates for motivated sellers, which are written to identify you and include an easy opt-out.
Compliance is not just legal cover. It is also deliverability. The same habits that keep you out of court, meaning identifying yourself, honoring opt-outs, and sane volume, are what keep carriers from flagging your number as spam.

Is cold texting motivated sellers legal?
It is heavily restricted. Under the TCPA, sending automated marketing texts to a cell phone without prior express written consent is illegal and carries $500 to $1,500 in damages per message. Some outreach is done manually to sidestep autodialer rules, but state laws and carrier rules still apply. The safe way is A2P 10DLC registration, honored opt-outs, legal send windows, and awareness of state restrictions.
What are the penalties for a TCPA violation?
TCPA damages are $500 per message, rising to $1,500 per message if the violation is willful or knowing. A single campaign of 1,000 non-compliant texts can create $500,000 to $1.5 million in exposure.
What is A2P 10DLC and do I need it?
A2P 10DLC is the carrier registration system for business texting on standard 10-digit numbers. It is required for deliverability; without it, carriers filter or block your messages. It does not by itself make cold texting legal. You still need to follow consent, opt-out, and state rules.
Which states restrict cold texting the most?
Texas SB 140 effectively requires consent before commercial texts and expands liability, Florida has the FTSA, and Oklahoma and Washington have strict rules. A compliant operation avoids cold texting in the most restrictive states or works only consented data there.
Is cold SMS illegal?
Cold SMS is illegal when it is a marketing message sent to a mobile number without prior express written consent, which describes most cold SMS. It is legal when you have documented consent, when the message is transactional rather than promotional, or in some cases when it is typed manually one recipient at a time. The medium is not banned; sending without permission is.
Is cold texting illegal in the US specifically?
Yes, in the sense that the federal TCPA applies nationwide and prohibits autodialed marketing texts to cell phones without written consent. Several states then layer stricter mini-TCPA statutes on top, notably Texas and Florida. There is no US jurisdiction where unconsented commercial cold texting to consumer cell phones is clearly safe.
Is cold texting for B2B legal?
Lower risk, not zero risk. The TCPA is aimed at wireless consumer numbers, so texting a published landline business number sits outside its core. The problem is that a large share of business contact numbers today are mobile numbers, and courts look at the number, not the job title. Treat B2B cold texting as reduced exposure rather than an exemption.
Does an opt-out link make cold texting legal?
No. Honoring STOP is required, but it is a floor, not a defense. The TCPA violation happens when the first unconsented message is sent. Adding an opt-out to a message you were not allowed to send does not cure it.
How do I text sellers without getting my number flagged?
Register A2P 10DLC, warm up numbers slowly, keep messages short and personal, identify yourself, honor STOP instantly, stay inside legal send windows, and scrub the Do Not Call list. Better still, use a system that handles all of this for you. For context on what this does to your economics, see how much motivated seller leads cost.
