Texting your clients legally: what every service business owner needs to know

Why texting is regulated in the first place

Text messaging has one of the highest open rates of any communication channel, hovering around 98 percent. That effectiveness is exactly why federal regulators stepped in. The Telephone Consumer Protection Act (TCPA), enacted in 1991 and enforced by the Federal Communications Commission (FCC), was originally written to address robocalls. Over time, courts and regulators extended its reach to cover automated and bulk text messages as well.

The TCPA is not a technicality. Violations carry statutory damages of $500 to $1,500 per message, and class action lawsuits are common. A business that sends 500 unsolicited texts could face fines ranging from $250,000 to $750,000. The law is enforced both by the FCC and through private lawsuits filed directly by consumers.

Beyond the TCPA, the Cellular Telecommunications and Internet Association (CTIA) sets industry-level guidelines that mobile carriers use to filter and block non-compliant messages. If your messages do not meet carrier standards, they simply will not be delivered. Compliance is not just a legal issue. It is a deliverability issue.

The single most important rule: consent first

Before you send any marketing or promotional text message, you must have the recipient's prior express written consent. This is not optional, and it cannot be assumed. The TCPA distinguishes between two levels of consent depending on the type of message you are sending.

Implied consent applies when a client has given you their phone number in the context of an existing business relationship, such as booking an appointment or making a purchase within the past 18 months. You can send them transactional messages related to that relationship without a formal opt-in. However, you cannot use implied consent to send promotional messages.

Express written consent is required for any promotional or marketing text. This means the client must actively agree, in writing, to receive marketing messages from you specifically. A checkbox on a booking form, a keyword reply like "YES" or "JOIN," or a signed paper form all qualify. What does not qualify is a buried clause in general terms and conditions, or consent obtained by a third party on your behalf.

What your first message must include

The first text message a new contact receives from your business carries specific legal requirements. It must clearly identify who is sending the message, explain what kind of messages the recipient can expect, state how often messages will be sent, disclose that message and data rates may apply, and provide clear instructions for opting out.

With Frontrunners Connections, this first message is sent automatically as part of your onboarding setup. We configure the opt-in language, the STOP and HELP keyword responses, and the consent record-keeping so that your program is compliant from the very first text.

A2P 10DLC registration: what it is and why it matters

Since February 2025, all businesses sending text messages to U.S. phone numbers must be registered through the A2P 10DLC (Application-to-Person, 10-Digit Long Code) system. This is a carrier-level requirement, not a government law, but the practical effect is the same: unregistered messages are filtered or blocked by major carriers including AT&T, T-Mobile, and Verizon.

A2P 10DLC registration involves verifying your business identity with The Campaign Registry (TCR), a third-party organization authorized by U.S. carriers. The registration process requires your Employer Identification Number (EIN) or equivalent tax ID, your business address, a description of how you use SMS, sample message content, and documentation of your opt-in and opt-out processes.

Opt-out: making it easy is not optional

Under both the TCPA and updated FCC rules that took effect in April 2025, consumers have the right to revoke their consent to receive text messages at any time, through any reasonable means. You cannot restrict opt-out to a single method. If a client replies "stop," "unsubscribe," "quit," "cancel," or any similar word, you must honor that request promptly.

Once a contact opts out, you have a limited window (generally 10 days under current FCC guidance) to send a single confirmation message. After that, you must not send any further messages to that number unless the person explicitly re-subscribes.

Maintaining a do-not-contact (DNC) list is essential. If someone opts out and you accidentally text them again, that is a separate TCPA violation. Frontrunners Connections automatically records opt-outs and suppresses those numbers from future sends, so you are protected even if you forget.

Content you cannot send

The CTIA's SHAFT guidelines prohibit certain categories of content across all carrier networks, regardless of consent. SHAFT stands for Sex, Hate, Alcohol, Firearms, and Tobacco. Specifically:

• Adult or sexually explicit content may not be sent without robust age verification systems in place.
• Content that promotes, glorifies, or depicts violence, hate speech, or discrimination is prohibited.
• Alcohol and legal cannabis content requires age-gating and cannot be sent to general lists.
• Firearms and tobacco content is subject to strict restrictions and age verification requirements.
• Promotion of illegal drugs or controlled substances is prohibited entirely.

Beyond SHAFT, you may not send messages that are deceptive or misleading, that impersonate another business or individual, or that contain phishing links. Violating these guidelines can result in your messaging number being permanently banned by carriers.

When you can and cannot text: time-of-day rules

The TCPA prohibits sending promotional text messages before 8:00 a.m. or after 9:00 p.m. in the recipient's local time zone. This applies to each individual recipient, not your own time zone. If you are in Texas and texting a client in California, you must use California time.

Texas Senate Bill 140, which took effect September 1, 2025, imposes an earlier cutoff of 8:00 p.m. for solicitation-related messages sent to Texas residents. The law also limits businesses to no more than three solicitation contacts within a 24-hour period to the same person. Because Frontrunners Connections is based in Texas and serves many Texas-based businesses, we recommend treating 8:00 p.m. as your universal cutoff for any promotional sends.

Texas-specific rules: what SB 140 means for you

Texas Senate Bill 140 significantly expanded the state's telemarketing law to include text messages. The good news: the Texas Attorney General clarified in December 2025 that businesses sending text messages with prior consent of the consumer are not required to complete the state's Telephone Solicitation Registration Statement. This means that if you are using Frontrunners Connections properly, with documented opt-in consent from every contact you text, the most burdensome registration requirements do not apply to you.

However, the quiet hours restriction (no texts before 8 a.m. or after 8 p.m.) and the frequency limit (no more than three solicitation contacts per 24-hour period) do apply regardless of consent. Class action exposure under SB 140 remains a real risk, so these timing rules should be treated as firm limits, not suggestions.

What Frontrunners Connections does to keep you protected

We built compliance into the platform from the ground up, because we believe that protecting your business is part of the service. Here is what we handle on your behalf:

What remains your responsibility

Even with a compliant platform, the legal obligation for how you use it rests with you. Specifically, you are responsible for:

• Collecting consent properly. You must obtain opt-in from your contacts before adding them to any messaging list. Do not import lists of phone numbers without documented consent for each contact.
• Sending only what you said you would send. If someone opted in to receive appointment reminders, you cannot start sending them promotional offers without a separate opt-in for that purpose.
• Keeping your contact list clean. Remove contacts who have not engaged in over 18 months, and never purchase or rent phone number lists.
• Sending truthful, non-deceptive messages. Your business name must be clearly identifiable in every message. Do not use misleading sender IDs or deceptive content.
• Respecting individual requests. If a client asks you to stop texting them in any way, including verbally or by email, you must honor that request even if they have not replied STOP.
