What Constitutes Legal Consent?
Knowing is SMS marketing legal starts with understanding consent. Proper consent starts with express written consent, such as checking an opt-in box or signing a form. For guidance on running effective campaigns, see How to Use SMS Marketing: A Complete Guide for Businesses.
Consent hidden in terms of service, implied from past interactions, or obtained through third parties does not meet legal standards. Businesses must also document consent carefully, including method, date, phone number, and exact wording. Proper consent ensures your campaigns comply with the law and protects your business from penalties.
Express Written Consent
The safest way to ensure is SMS marketing legal is to get express written consent. Customers must clearly agree to receive messages, knowing what type of texts they’ll get, how often, and from whom. This can be done through an opt-in box, a text message, a signed form, or a digital consent process. Properly documenting consent helps keep your campaigns fully compliant and avoids potential fines.
Valid consent methods include:
- Checking a box on a web form specifically for SMS marketing
- Sending a text message to opt-in to a campaign
- Signing a physical form that clearly explains SMS marketing terms
- Completing a digital signature process
What Doesn’t Count as Valid Consent
Several common practices do not constitute legal consent:
- Pre-checked boxes on web forms
- Consent buried in terms of service agreements
- Implied consent from existing business relationships
- Consent obtained through third parties without proper documentation
Consent Documentation Requirements
Businesses must maintain detailed records of how and when consent was obtained. This documentation should include:
- The method used to obtain consent
- The exact language presented to consumers
- Date and time stamps
- The specific phone number that consented
- Any additional relevant context
Compliance Best Practices
Understanding is SMS marketing legal is just the first step; following best practices ensures your campaigns remain fully compliant and effective. Simply obtaining consent isn’t enough—businesses must also manage message content, timing, frequency, and opt-out processes carefully.
Message Content Requirements
Every marketing text message must include:
- Clear identification of the sender
- Opt-out instructions (typically “Reply STOP to opt out”)
- Contact information for customer service
- Truthful and non-misleading content
Timing Restrictions
The TCPA prohibits sending marketing messages outside of reasonable hours. Generally, this means:
- No messages before 8 AM or after 9 PM in the recipient’s time zone
- Consideration of weekends and holidays
- Respect for time zone differences across your customer base
Frequency Limits
While there’s no specific federal limit on message frequency, sending too many messages can violate the spirit of consent laws. Best practices include:
- Setting clear expectations about message frequency during the opt-in process
- Monitoring engagement rates and adjusting frequency accordingly
- Providing options for customers to reduce message frequency without fully opting out
Common SMS Marketing Violations
Knowing is SMS marketing legal is only half the battle—understanding the common violations can help your business avoid costly mistakes and stay compliant. Avoid sending messages without consent, ignoring opt-outs, or using misleading content. For strategies to recover from or prevent errors, visit How to Win Back Customers with SMS Retargeting. Here are some of the most frequent SMS marketing pitfalls that can land businesses in legal trouble:
Sending Messages Without Consent
One of the most serious violations is sending marketing texts to people who haven’t explicitly opted in. Simply having a customer’s phone number does not mean you have legal permission to message them. Purchasing phone number lists or relying on implied consent is illegal under federal law, and can result in penalties of hundreds or even thousands of dollars per message. This is a key area where understanding is SMS marketing legal becomes critical for business owners.
Inadequate Opt-Out Mechanisms
Another common mistake is failing to provide a clear and easy way for recipients to unsubscribe. Every marketing message must include a simple opt-out option, typically a “Reply STOP” instruction. If customers find it difficult or confusing to opt out, your messages may be considered a violation of consumer protection laws, leading to complaints and potential fines.
Ignoring Opt-Out Requests
Even if an opt-out mechanism is in place, failing to honor requests immediately is a serious breach. Continuing to send messages after someone has opted out is not only illegal under the TCPA but also damages trust and brand reputation. Businesses must track opt-outs carefully and ensure their SMS platform automatically enforces these requests.
Using Misleading Content
Sending false or misleading information in text messages is another violation that can have legal consequences. This includes deceptive offers, unclear terms, or messages that misrepresent your brand or products. Misleading content can trigger regulatory action and consumer lawsuits, highlighting why understanding is SMS marketing legal is essential before crafting campaigns.
By avoiding these common violations and following compliance best practices, businesses can use SMS marketing effectively while staying on the right side of the law.
Penalties for Non-Compliance
Understanding is SMS marketing legal also means knowing the risks of non-compliance. Violating SMS marketing laws can result in serious financial and legal consequences for businesses of all sizes.
TCPA Penalties
Individual consumers can sue for:
- $500 per violation (each unwanted message)
- Up to $1,500 per violation if the violation was willful
- Attorney fees and court costs
FCC Enforcement Actions
The FCC can impose much larger penalties:
- Fines up to $46,000 per violation
- Cease and desist orders
- Additional compliance monitoring requirements
State-Level Penalties
State laws may impose additional penalties, including:
- Criminal charges in some jurisdictions
- Business license revocation
- Additional civil penalties

Frequently Asked Questions (FAQ)
Is SMS marketing legal for small businesses?
Yes, SMS marketing is legal for businesses of all sizes as long as they comply with applicable laws such as the TCPA, FCC regulations, and relevant state laws. Small businesses are held to the same standards as large enterprises, meaning consent and opt-out requirements apply equally.
Can I text customers who gave me their phone number at checkout?
Providing a phone number alone does not constitute consent for marketing messages. Customers must explicitly agree to receive promotional texts, and that consent must be clearly documented.
Do I need consent for transactional SMS messages?
Yes, some level of consent is still required, but transactional messages generally fall under implied consent when they are necessary to deliver a service the customer requested. However, adding promotional content changes the legal requirements.
How long should I keep SMS consent records?
Most legal experts recommend retaining consent records for at least four years, though longer retention may be advisable depending on your industry and jurisdiction.
What happens if someone texts STOP?
You must immediately stop sending messages to that number. Failure to honor opt-out requests promptly is a direct violation of SMS marketing laws.
Can I buy an SMS marketing list?
No. Purchased lists do not provide valid consent and using them is one of the fastest ways to incur TCPA violations and carrier bans.
Are international SMS laws different from U.S. regulations?
Yes. Countries like those in the European Union and Canada have stricter consent and data protection requirements. If you message international customers, you must comply with local laws in addition to U.S. regulations.
