Text messaging is the highest-open-rate channel a small business has. Ninety-eight percent of texts get read, most within three minutes. But the same channel that can fill your schedule on a slow Tuesday can also hand you a federal lawsuit if you skip the compliance basics. This guide covers what the law requires, how often to text, and what to actually say so people reply instead of opting out.
What Is TCPA and Why Does It Apply to Your Business?
The Telephone Consumer Protection Act (TCPA) is a federal law that governs how businesses can contact people by phone and text. It was written in 1991 and updated repeatedly since then. The short version: you cannot send marketing texts to someone without their prior express written consent, and you cannot use an automated system to send those texts to someone who never gave you permission.
The penalties are not symbolic. Each violation can cost between $500 and $1,500. If a court finds the violation was willful, the higher end applies. A list of 500 contacts texted without proper consent is not a minor compliance gap — it is potential exposure in the hundreds of thousands of dollars. Small businesses get sued under TCPA regularly, and class actions are common.
The good news: compliance is not complicated. It requires a clear opt-in process, an easy opt-out mechanism, and a record of both. Build those three things into your workflow from the start and you are protected.
What Counts as Valid Opt-In?
TCPA requires prior express written consent for marketing messages. That phrase has a specific legal meaning. The person must affirmatively agree — checking a pre-checked box does not count. They must know what they are agreeing to. And the agreement must be in writing, which includes digital forms.
Valid opt-in examples:
- A web form where the customer types their number and checks an unchecked box that says: "I agree to receive marketing texts from [Business Name] at this number. Message and data rates may apply. Reply STOP to opt out."
- A paper sign-up sheet at your counter with the same disclosure language and a signature line.
- A keyword opt-in where the customer texts a word like JOIN to your number after seeing a posted sign that explains what they will receive.
What does not count as valid consent: having someone's number from a past transaction, buying a contact list, or getting a number from a business card. Transactional texts — appointment reminders, order confirmations, payment receipts — operate under a lower standard called prior express consent, but marketing messages require the full written version.
Always store your opt-in records. If you are ever challenged, you need to show when someone opted in, what they agreed to, and through what channel.
How Often Should You Text? The Cadence Question
Frequency is where most small businesses either underuse SMS or burn their list. The right cadence depends on your business type, but a general framework holds across industries.
For most service businesses, one to four texts per month is the range that keeps open rates high and opt-outs low. Retailers and restaurants can push toward the higher end around promotions and slow periods. Professional services — accountants, attorneys, consultants — should stay closer to one or two per month unless a message is clearly time-sensitive.
The rule underneath the rule: every text must earn its place. If you cannot answer "why does this person need this message today," do not send it. Irrelevant frequency is what drives opt-outs, not frequency itself. A well-timed text about a service the customer actually needs feels helpful. A generic promotional blast feels like spam regardless of how often you send it.
Also respect quiet hours. TCPA restricts calls before 8 a.m. and after 9 p.m. in the recipient's local time zone. Many compliance-minded businesses apply the same window to texts. It is good practice even where not strictly required.
What Should You Actually Say?
SMS is not email. You have 160 characters in a standard segment, and people read texts in two seconds. Structure every message around one action and one reason to take it.
A message that works: "Your HVAC tune-up reminder — we have openings this week before the heat hits. Reply YES to book or call us at [number]. Reply STOP to opt out."
A message that does not work: "Hi! We're [Business Name] and we have some great deals this month on all our services. Check out our website for more info and let us know if you have any questions!"
The first message is specific, time-relevant, and tells the reader exactly what to do. The second is vague, asks for nothing clear, and gives the reader no reason to act now.
Every marketing text must include your business name (if it is not obvious from the sender ID), a clear call to action, and an opt-out instruction. "Reply STOP to opt out" is the standard language and it must be there.
Illustrative Cost Comparison: SMS Platforms vs. Pocket Boss
Many small businesses piece together a standalone SMS tool, a CRM, a scheduling app, and a separate invoicing platform. The monthly tab adds up fast.
| Tool | Typical standalone cost |
|---|---|
| SMS marketing platform | $50–$150/mo |
| CRM software | $75–$200/mo |
| Scheduling app | $30–$80/mo |
| Invoicing tool | $25–$60/mo |
| Total stack | $180–$490/mo |
| Pocket Boss Start | $100/mo, no setup fee |
Pocket Boss Start includes texting, CRM, invoicing, scheduling, and Alli, the built-in AI assistant. A business replacing a four-tool stack with Pocket Boss Start saves a conservative $80 to $390 per month — $960 to $4,680 per year — before counting the admin hours saved by having everything in one place instead of four.
Does Pocket Boss Handle TCPA Compliance Automatically?
Pocket Boss is built with compliant opt-in and opt-out mechanics. When you collect a contact through a Pocket Boss form, the consent language is part of the form. When someone replies STOP, they are removed from marketing sends automatically. Opt-in records are stored so you have documentation if you ever need it.
Alli, the AI assistant inside Pocket Boss, can help you draft message templates, suggest send timing based on your audience, and flag messages that are too long or missing required disclosures before they go out. It does not replace legal advice, but it does catch the common mistakes that get small businesses in trouble.
The system also connects texting to the rest of your workflow. A new estimate can trigger a follow-up text. A completed job can trigger a review request. An unanswered call triggers a text-back within seconds. These automations run on the same opt-in consent you collected at the start, so you are not creating new compliance exposure every time you add a workflow.
Values above are illustrative estimates based on typical standalone tool pricing. Your actual costs depend on the tools you currently use.
Is SMS Marketing Worth It for a Small Business?
For most small businesses, yes — with the right setup. The channel has higher open rates than email, lower cost than paid ads, and faster response times than almost any other outreach method. A cleaning company that texts its recurring clients a monthly slot reminder fills its calendar without a phone call. A salon that texts a Tuesday-morning slow-day offer fills two chairs by noon. A contractor who follows up an unsent estimate with a single text closes jobs that would have gone cold.
The businesses that get burned by SMS marketing are the ones that skip consent, blast too often, or send messages with no clear point. The businesses that build it correctly — opt-in at the point of contact, one to four relevant messages per month, clear calls to action, automatic opt-out handling — see it become one of their most reliable revenue levers.
The compliance setup takes about an afternoon. The payoff runs for years.
