Court Rules Text Message STOP May Also End Marketing Calls

For marketers, “STOP” has always been one of the clearest signals a consumer can send. But a recent federal court decision is raising a more complicated question: when someone texts “STOP” to opt out of marketing messages, does that also mean a business has to stop calling them?

A Florida federal judge recently said it may.

In Zagury v. Puragin Water, the plaintiff alleged that she revoked her consent to be contacted after replying “STOP” to an SMS message. The company did not dispute that the text revoked consent for future SMS messages, but argued that it could continue making calls because the opt-out had been made through the text channel.

The court disagreed, finding that the “STOP” request could apply to both calls and texts.

The ruling is especially relevant for marketers managing campaigns across multiple channels. It also highlights a larger compliance challenge: an opt-out is not simply a message to remove someone from one campaign. It can become an instruction that needs to flow across an entire marketing system.

What The Court Actually Decided

The case centers on the Telephone Consumer Protection Act, or TCPA, which governs certain calls and text messages and gives consumers rights around consent and revocation.

The Federal Communications Commission has previously stated that consumers can revoke consent using reasonable means. Its 2024 order specifically addressed text-based revocation and stated that when a consumer revokes consent through a reply text, the revocation can extend to both robocalls and robotexts from that caller.

That distinction matters because many marketing teams still organize communication preferences by channel.

A contact might be marked as opted out of SMS while remaining eligible for a phone call, email, or another type of outreach. The Zagury decision suggests that this approach can create risk when the applicable consent rules treat the opt-out more broadly.

There is also an important caveat. The National Law Review analysis points out that the Florida court relied in part on an FCC revocation provision that had been delayed and was not yet in effect. The broader legal landscape is therefore still developing.

For marketers, however, waiting for every legal question to be settled may not be the safest strategy.

Why A Simple “STOP” Can Become A Complex Compliance Problem

The real challenge is not recognizing the word “STOP.” Most marketing platforms can do that automatically.

The challenge is what happens next.

A consumer might receive an SMS from a company, reply “STOP,” and then receive a sales call the following day because the calling system does not share the SMS platform's suppression list.

That creates a gap between consumer intent and marketing execution.

For teams managing large volumes of campaigns, several things need to happen:

  1. The opt-out needs to be captured. The system must recognize the consumer's request rather than treating it as an ordinary reply.

  2. The preference needs to be recorded centrally. The information should not live only inside the SMS platform that received the response.

  3. Other marketing channels need to receive the signal. If the opt-out may apply to calls as well as texts, downstream systems need to know about it.

  4. Future campaigns need to respect the updated status. A contact should not be accidentally reintroduced through a new campaign, list upload, or sales workflow.

  5. The business needs evidence of what happened. Records showing when the request was received and how it was processed can become important if compliance is later questioned.

This is where marketing compliance stops being a policy problem and becomes an operational one.

The Bigger Lesson: Consent Needs To Follow The Customer

The most important takeaway from the ruling is not simply “stop calling people who text STOP.”

It is that consent and revocation need to be managed as customer-level information, not isolated campaign-level information.

That becomes increasingly important as businesses use more channels and more automated marketing systems.

A consumer does not necessarily think in terms of marketing databases, campaign IDs, CRM fields, SMS providers, or sales sequences. They think in terms of one company contacting them.

If they say, “Stop contacting me,” they expect that instruction to be understood.

Marketing technology, meanwhile, may interpret the same person as several different records across several different systems.

That disconnect creates compliance risk.

The FCC has already emphasized that consent is connected to the consumer and the number being contacted, rather than simply the method used to communicate the revocation.

For marketers, this means consent management should be designed around the customer's communication preference, with clear rules for how that preference propagates across campaigns and channels.

What Marketing Teams Should Do Now

Until the courts and regulators provide more clarity, a conservative approach can help reduce unnecessary exposure.

  1. Treat clear opt-outs seriously. Words such as “STOP,” “QUIT,” “END,” “REVOKE,” “OPT OUT,” “CANCEL,” and “UNSUBSCRIBE” are specifically recognized as standard revocation language in the FCC's rules.

  2. Review cross-channel suppression. Determine whether an SMS opt-out can automatically suppress calls and other relevant outreach, rather than assuming each channel operates independently.

  3. Audit your integrations. Check whether CRM, marketing automation, sales engagement, SMS, and calling systems are actually sharing consent and suppression data.

  4. Preserve an audit trail. Record the opt-out, when it was received, what consent it affected, and when suppression was applied.

  5. Test edge cases. Don't only test a perfect “STOP” response. Consumers may use phrases such as “don't text me,” “remove me,” or “please stop contacting me.” The FCC has indicated that other language can also constitute a valid revocation when a reasonable person would understand it as a request to stop.

  6. Make compliance part of campaign workflows. A campaign should not be considered ready simply because its creative and targeting are approved. The underlying consent and suppression logic needs to work too.

Compliance Can't End At Campaign Approval

The Zagury ruling is another reminder that marketing compliance is not just about reviewing what a company wants to say. It is also about controlling who can receive it, through which channel, and what happens when that person says no.

That becomes harder when marketing teams operate across disconnected tools.

A compliant campaign can still create problems if an old list is uploaded into a new platform, a sales sequence ignores a recent opt-out, or a calling system does not receive suppression information from an SMS provider.

The safest approach is to make consent part of the marketing workflow itself.

For organizations operating in regulated environments, that means having a clear system of record for marketing assets, approvals, policies, and the rules that determine whether communications can go out in the first place.

Because when a customer says “STOP,” the hardest part should not be figuring out what they meant. It should be making sure every relevant system actually stops.
