You already have your customers' phone numbers, and you would like to text them about appointments, open slots and the occasional offer. You also keep hearing about fines, about providers asking you to register, and about the one angry reply that turns into a complaint. Text message marketing for a local business works well when the permission is solid, and it goes wrong fast when it is not.
The short answer to "do I need permission?" is yes. Marketing texts sent with an autodialer or prerecorded system generally need prior express written consent. That consent has to name the seller, the number being texted, and the customer's agreement to receive marketing texts.
A customer can take that permission back in any reasonable way, including a reply of STOP. You can send one confirmation text after that, and it cannot contain any marketing.
Federal quiet hours are generally 8 a.m. to 9 p.m. in the customer's local time, and state rules can be stricter. Start with permission, then choose what to send, settle how often, and learn to tell whether it paid for itself.
Key Takeaways
Marketing texts sent with an autodialer or prerecorded system generally need prior express written consent that names you, the number, and the customer's agreement to receive marketing texts.
Consent can be revoked in any reasonable manner, and you may send one confirmation text with no marketing in it.
A2P 10DLC registration vets the sender and the campaign. Your own consent records are what show a customer agreed.
Track booked appointments, redeemed offers and opt-outs, because a message that reached a phone has not yet earned anything.
Know what permission you need before the first text
Start by sorting your messages into two piles. A text that confirms or changes something the customer already arranged, such as a Tuesday appointment, is a different kind of message from a text that tries to sell something. The promotional pile is where the strict consent rules apply, and it is where the trouble starts.
For marketing texts sent with an autodialer or prerecorded system, the FCC's consent order and the rule text in 47 CFR 64.1200 call for prior express written consent. In practice, the sign-up has to say who is sending, which number will get the texts, and that the customer agrees to receive marketing texts.
Handing you a phone number is not that agreement. A customer who gave you a number so you could call about a repair has not agreed to a monthly coupon text, and one general checkbox on a website does not cover every future campaign.
The wording matters as much as the checkbox. A sign-up line such as "Text me appointment openings and offers from your shop at this number, up to four messages a month, reply STOP to quit" names the sender, the topic and the pace in one breath. Write yours so a customer could repeat back what they agreed to.
State law is the other half. The federal rules set a floor, and your state may add to it. The Connecticut rules for telemarketing and texting show how a state layer can change sending windows and requirements, so look up your own state before you schedule anything.
Stop a promotional send the moment someone replies STOP
A customer can revoke consent "in any reasonable manner," and the FCC names a reply of STOP or a similar word as one of those ways. The CTIA Messaging Principles go further and say senders should honor ordinary words such as stop, end, unsubscribe, cancel and quit. Your system should treat all of them the same way.
After someone opts out, you may send exactly one confirmation text. It confirms the opt-out and contains no marketing, no "come back and see us," and no coupon. Then the number stays off your promotional list.
The FCC's order also sets an outside limit of ten business days for honoring a revocation. Treat that as the worst case, not the target. A texting tool that suppresses the number the moment STOP arrives keeps you well inside it. The FCC has also extended the effective date of its cross-campaign "revoke all" provision to January 31, 2027, according to its 2026 order, so check the current date before you rely on that detail.
Timing is part of the same discipline. Schedule promotional sends between 8 a.m. and 9 p.m. in the customer's local time, and shorten that window if your state does. If your customers live in more than one time zone, store where each one is so the system can send at the right hour for each of them.
Keep your sending number approved by registering the business
Registration is the step providers keep asking about, and it is easy to confuse with permission. A2P 10DLC is the carrier-approved system for application-to-person texts sent from ordinary 10-digit numbers. As Twilio describes it, a small business normally registers its brand, describes each messaging campaign, supplies sample messages, explains how customers opt in, and ties the campaign to a sending number.
Which path you take depends on your business. A business with an EIN usually registers as Low-Volume Standard or Standard. A sole proprietor without an EIN can use a Sole Proprietor Brand where it is supported, generally with lower sending speed and one campaign, as Twilio's business information guide explains.
What registration does is identify and vet the sender and the use case. What it does not do is create customer consent. You still have to collect and keep proof that each person agreed, and an approval from your provider does not make a particular message compliant. If a registered number is already having trouble reaching phones, our post on business texts that are not arriving covers that side in detail.
Check one subscriber record in ten minutes
You can find out where you stand this afternoon. Open your texting tool and look at one active subscriber, then read what the record actually holds. A usable record shows the phone number, the date of consent, how the customer consented, the exact sign-up wording or campaign, the page or keyword they used, the kind of messages they agreed to, the promised frequency, and whether they have opted out.
Then test the opt-out. Send yourself a promotional message from a test number, reply STOP, and confirm the contact's status changes at once and that a second promotional send is blocked. Check that the tool keeps a timestamped history and that your staff can export it.
If the record holds only a phone number and a generic "subscribed" label, you cannot show what that customer agreed to receive. Twilio's messaging policy asks for informed, sender-specific consent, proof of that consent, sender identification and a one-step opt-out. Even if you use a different provider, those four items make a sensible standard for your own records.
The same check works for the whole list, one batch at a time. Pull the numbers that came from the web form, then the ones from checkout, then the ones staff typed in by hand, and look at each group's records. The groups with gaps are the ones to hold back.
Send texts customers expect, at the pace you promised
Once permission is in place, the best texts are the ones that match the relationship. Appointment confirmations, rescheduling notes, service-status updates, pickup alerts and a review request after a finished job all fit an existing customer. Time-limited offers fit when they match what the customer signed up to hear about.
| Message type | What it does for the customer | What to keep on record |
|---|---|---|
| Appointment confirmation or change | Confirms the time they booked | Booking date and the number used |
| Service-status or pickup alert | Tells them their job or order is ready | The job or order it refers to |
| Review request after a finished job | Makes it easy to share how it went | Job completion date |
| Open-slot notice | Fills a cancelled time for people who asked | Their opt-in for open slots |
| Time-limited offer | Gives a reason to book this week | Opt-in wording that names offers |
Say how often you will text when the customer signs up, and then keep to it. The wording can be as plain as "up to four messages per month." There is no single frequency from the FCC or CTIA that suits every business, so the number you promise is the number that counts. Twilio's compliance guide adds that you should identify yourself in the message, repeat the opt-out instructions from time to time, and watch your opt-outs and complaints.
A good first text names the business and gives a way out. "This is [your business name]. Your 2 p.m. appointment is confirmed. Reply STOP to opt out" does both in one line. Notice that it has no offer in it, because a confirmation and a coupon are different messages with different rules.
If you ask for reviews by text, keep the request separate from any reward. Our post on getting more reviews covers how to ask, and the one on discounts for reviews covers why a reward changes the picture.
See which texts book jobs, not only which ones arrived
A text that reached a phone has not yet done anything for your business. Track the things that move money: booked appointments, redeemed offers, revenue from those bookings, the cost of each booking, replies, opt-outs, complaints and blocked or filtered messages. Twilio's Messaging Insights shows delivery and error data, and campaign tools commonly report clicks and unsubscribes on top of that.
To connect a text to a result, give each campaign something that can be counted. That can be a unique coupon code, a booking link with a UTM tag, a landing page made for that text, or a field at the register that asks which text brought the customer in.
| Number | What it tells you |
|---|---|
| Booked appointments | Whether the text caused action |
| Redeemed offers | Whether the offer was worth what it cost |
| Opt-outs per send | Whether the list or the message is wrong |
| Complaints | Whether people expected the message |
| Blocked or filtered messages | Whether a carrier is stopping you |
Keep your confirmations apart from your promotions in the report, or the busy confirmations will make a weak offer look healthy. To keep opt-outs low, send each offer only to the people it fits, keep to the frequency you promised, state the offer clearly, name your business, and process every STOP the moment it arrives, as Twilio's compliance toolkit recommends.
A claimed industry open rate is not a number to chase. A smaller list of people who agreed, and who get messages that suit them, will usually serve you better than a bigger list with unclear permission.
Fix the list first, even if it means sending less
If you pulled several records and found gaps, the useful move is to repair intake before you send a campaign. That may mean delaying the first promotion until your sign-up wording and records are adequate. It may mean setting aside the part of your list with no defensible permission, and texting only the people who clearly agreed.
Fixing it is mostly ordinary work. Change the form, the checkout line or the front-desk script so the exact permission is recorded. Turn on your provider's opt-out handling and test every standard keyword. Store each customer's location so quiet hours work. Complete brand and campaign registration with accurate sample messages. A small list audit can take hours, while a business with several locations or several systems may need weeks.
For the people you cannot text yet, other channels are still open. A longer, lower-urgency message belongs in email, and our guide to how often to email your customer list helps you set that pace. A one-to-one call or a message the customer starts is also fair game, because it answers something they asked.
Sending fewer messages in the first month is a reasonable price for a program you can defend later. Provider approval, a high arrival rate and a registered number are good signs, but none of them stands in for the customer's own yes.

Frequently Asked Questions About Text Message Marketing
Do you need permission to text customers?
For marketing texts sent with an autodialer or prerecorded system, generally yes: prior express written consent that names the seller, the number and the customer's agreement to receive marketing texts. Appointment confirmations a customer asked for are a separate kind of message from promotions. Check your state's rules too, since they can be stricter.
Does 10DLC registration replace consent?
No. Registration identifies and vets the sender and the campaign. You still need to collect and keep proof that each customer agreed to receive your messages.
What time can a business send marketing texts?
Federal quiet hours are generally 8 a.m. to 9 p.m. in the customer's local time. Some states set a narrower window, so confirm yours before scheduling.
How often should you text customers?
Use the frequency you promised at sign-up, such as "up to four messages per month," and adjust based on complaints, bookings and opt-outs. Neither the FCC nor CTIA sets one schedule for every business.
Can customers opt out with a word besides STOP?
Yes. CTIA's principles call for honoring ordinary requests such as end, unsubscribe, cancel and quit, and the FCC says consent may be revoked in any reasonable manner.
What should your first text say?
Name your business, say what the message is about, and give a clear way out, such as "Reply STOP to opt out." Keep any offer out of a confirmation.
What This Means for You
Text message marketing for a local business starts with permission you can prove. Get a clear yes that names you and the marketing, honor STOP the moment it arrives, send inside the quiet hours that apply to your state, and treat registration as a check on your business rather than a replacement for the customer's agreement. Then choose message types that fit the relationship and keep the pace you promised.
The payoff is a list of people who agreed to hear from you, which gives you fewer surprises when a STOP or a complaint comes in. You can read the results in appointments and redeemed offers, which beats counting how many messages arrived.
