Text Messaging and SMS Compliance Rules Marketers Should Know

If you’re considering adding text messaging to your marketing mix, SMS compliance should be a core part of your plan. Text messaging offers marketers the ability to reach shoppers more directly and with fewer distractions than other channels. Yet texting can also invade consumer privacy and feel pushy if done poorly. That’s part of why many countries and regions have introduced SMS-related compliance standards.

TCPA and CAN-SPAM in the United States, CASL in Canada, and GDPR and the ePrivacy Directive in the European Union all lay out standards for text marketing and penalties for non-compliance. Failure to align with these standards may result in financial and reputational risks.

We take a closer look at text marketing today, including the regulatory considerations businesses may want to be aware of.

More Business Are Using Text Marketing

As soon as mobile phones became popular, attempts to use them for marketing purposes were inevitable. Today, mobile phones are ubiquitous. About 98% of adults in the U.S. own a cellphone and other countries have a similar use rate.

As a result, both legitimate businesses and less reputable people have embraced the potential for reaching customers through SMS or text messaging. Today, about 66% of businesses use SMS marketing. to communicate with customers. The leading users of this technology are the healthcare, hospitality and finance industries.

Ecommerce and retail organizations have a low adoption rate, despite the fact that consumers say they want to receive texts from businesses in these industries. Beyond customer service and satisfaction surveys, messaging can be used for new product or service offerings, abandoned cart follow-ups, and to share discounts, promotions, or sales alerts.

Why Aren’t More Businesses Using Text Messaging?

Considering the potential value of text messaging, it may be surprising that only two-thirds of businesses are using it. The blame most likely falls on two main stumbling blocks.

1. Confusion over SMS compliance standards
2. Uncertainty over technical aspects of SMS marketing

Many businesses hesitate to adopt SMS due to the complexity of compliance and integration challenges, uncertainty over how to ensure compliance from a technical perspective, and integration challenges. Launch Labs’ solutions are specifically designed to simplify both, by combining real-time consent capture, lead qualification, CRM integration, and compliant SMS conversations into a single, seamless experience.

We’ll cover both of these challenges in the following sections so your organization can more confidently adopt SMS or text messaging.

Keep in mind that the best source of legal advice about any compliance issue is an attorney or data security professional. They can give specific, nuanced guidance on what is best for your organization. What follows is a general introduction into the regulations, requirements, and technologies relevant to SMS and texting for marketing purposes.

Text Marketing and SMS Compliance Standards to Know

Regulations that govern texting for business purposes vary by area. Applicability of these laws often depends on the location of your customers, not just where your business is based. In other words, if your U.S. business is texting customers in the EU, you need to understand EU consumer protection laws.

United States: TCPA and CAN-SPAM Act

The Telephone Consumer Protection Act (TCPA) regulates commercial text messaging to protect consumers in the United States. Businesses must get prior opt-in consent before sending marketing messages via text or SMS. Anyone on the national do not call registry is also protected from receiving marketing-related text messages.

Consumers should receive clear guidance on how to opt out of text messages from a particular organization. The process for opting out must be simple and accessible. Many organizations instruct recipients of text messages to “reply STOP” to opt out.

The CAN-SPAM Act primarily focuses on email, but it comes into play anytime an SMS message is sent to an email address. Under this regulation, businesses must clearly identify themselves, include truthful subject lines, and share clear opt-out mechanisms.

Organizations sending commercial messages to U.S. phone numbers or email addresses may be subject to both TCPA and CAN-SPAM.

Canada: CASL

Canada’s Anti-Spam Law (CASL) is a broad-reaching regulation covering all forms of commercial electronic messages — including text messages. Similar to TCPA, it requires businesses to gather express consent before messaging. Businesses contacting consumers in Canada must identify themselves honestly and provide clear opt-out instructions.

There are certain exemptions for pre-existing relationships, but in general, organizations sending commercial electronic messages within Canada or to individuals in Canada may fall under CASL requirements.

European Union: ePrivacy Directive + GDPR

Application of the ePrivacy Directive varies by member state within the EU. However, the core of the regulation as it relates to SMS and text messaging is that organizations must gain explicit consent before sending messages.

While the General Data Protection Regulation does not specifically address text messaging, it does govern how phone numbers used for messaging can be collected and stored. Phone numbers are generally considered personally identifiable information and may fall under GDPR-related data handling requirements.

General Consent Requirements for SMS and Text Messaging

All of the regulations mentioned above require organizations to get explicit consent from consumers before sending commercial electronic messages. Keep in mind that this consent must be opt-in consent.

Common Mistakes:

• Pre-checking boxes on consent forms
• Assuming consent for one type of communication implies consent for SMS
• Vague or unclear communication about what users are consenting to

Best Practices:

• Ask consumers to opt-in to electronic communication
• Get explicit consent for each type of communication
• Tell users what kinds of messages to expect

Solutions like Launch Labs’ Text-Based Chat AI capture SMS consent directly at the point of initial engagement, before continuing conversations. Consent records are automatically timestamped, securely stored, and synced to integrated CRM systems, reducing manual processes and supporting audit-ready documentation.

Double opt-in is widely regarded as a best practice to help protect your organization from compliance risks related to SMS messaging. In text messaging, double opt-in usually looks like this. First, a consumer checks a box on a website stating that they have opted in to receiving text messages. Then, the first message they receive asks them to reply “Yes” or make some other affirmative statement confirming their willingness to receive messages.

Maintaining alignment with SMS regulations typically involves more than just obtaining consent. It is recommended that organizations maintain records of consents and opt-outs to support accountability and transparency.

• Log when and how consent was given
• Track opt-outs to ensure compliance
• Respond swiftly to consumer requests

With modern SMS and text messaging technology, opt-outs should take effect instantaneously. When a consumer replies ‘STOP,’ the organization can send a confirmation of the opt-out, but otherwise, no additional texts should be sent.

Technology to Support Compliant SMS Messaging

The following tools empower organizations to send electronic messages and have structures in place to maintain compliance with relevant regulations. Each organization should evaluate whether partnering with these providers aligns with its compliance obligations and privacy expectations.

• Attentive - an AI-powered platform designed to provide personalized messaging at scale via SMS, RCS, and email.
• Postscript - offers SMS sales and marketing solutions with built-in features to ensure compliance.
