Text messages are the most effective channel for appointment reminders, follow-ups, and quick replies. They're also one of the few places where a small business can get into real trouble without meaning to. Most of the posts on this blog involve texting customers, so it's worth being direct about the ground rules.
A note before we start: this is general information for small business owners, not legal advice. Rules vary by situation and change over time, so talk to a qualified attorney about your specific setup.
Why this is worth five minutes
In the U.S., the Telephone Consumer Protection Act (TCPA) sets rules for automated and marketing text messages, and it allows people to sue for statutory damages of $500 per message, up to $1,500 per message if a violation is found to be willful. As an illustration of exposure, not a prediction: 200 automated texts to people who never agreed to receive them could, in theory, mean $100,000 in claimed damages. Most small businesses never face this, and it's rarely the plan. It's usually the result of a list nobody checked.
A plain-English checklist
- Get clear consent first. Customers should agree to receive texts, ideally at the moment they give you their number, in words they'd recognize: "Text me appointment reminders and updates." Marketing texts generally need a higher bar than reminders, so ask your attorney which applies.
- Keep a record. Note when and how each person agreed. If you can't show consent, you don't have it.
- Make opting out effortless. Honor "STOP" immediately, and don't text that person again about anything automated. Don't make anyone argue to leave.
- Identify your business in the message so people know who it's from.
- Mind the clock. Avoid sending automated messages late at night or early in the morning in the recipient's time zone.
- Register with the carriers. Business texting from standard local numbers generally requires registering your brand and use case, often called A2P 10DLC. Unregistered traffic can be filtered or blocked, which looks like "my texts stopped going through."
How good automation handles this
A well-built setup treats consent as a requirement, not an afterthought. It only texts people who opted in, stores when they did, stops the moment someone replies STOP, and goes through the carrier registration process with a provider like Twilio before anything is sent. It syncs opt-outs back to your records in ServiceTitan, Jobber, Housecall Pro, or your CRM so a customer who opts out of one system is out of all of them.

Where we draw a hard line
We don't text anyone who hasn't agreed to it, we don't buy or scrape lists, and we don't make it hard to say no. We also won't tell you that a particular setup is legally safe, because that's your attorney's call, not ours. What we will do is build the consent, opt-out, and registration steps in from day one so you start from a sound position.

Texting works because it feels personal, and that's exactly why people expect it to be a choice. Clear consent, an easy exit, and proper registration protect your customers and your business.
