Text messages have a 98% open rate. That number gets cited a lot in marketing circles, usually by people trying to sell you SMS software. What gets cited less often: the unsubscribe rate spikes the moment you start using that channel carelessly.
Here is what we’ve learned from watching service businesses use SMS well and badly over the past four years.
Why SMS works for service businesses specifically
Service businesses — clinics, salons, plumbers, personal trainers — have a natural rhythm to their customer relationships. Appointments create moments. Moments create legitimate reasons to send a message.
The problem with most marketing advice is that it’s written for e-commerce brands who are manufacturing reasons to reach out. You don’t need to manufacture anything. You already have the appointment.
The permission question
You need opt-in. This is not optional and it’s not just legal compliance — it’s practical. A list of people who asked to hear from you converts. A list of people who didn’t ask converts at roughly zero and burns the channel for the next time.
The cleanest way: ask at booking. “Would you like appointment reminders and occasional tips by text?” Most people say yes because most people want appointment reminders.
The three rules
Rule one: only send what you’d want to receive. If you find yourself thinking “well, we haven’t sent anything this month,” that is not a reason to send something.
Rule two: every message needs a reason to exist today. An appointment reminder has a reason. A “we miss you” message sent to anyone who hasn’t booked in three months has a reason. A “check out our spring specials” message has no reason.
Rule three: the reply path must be human. If someone replies to your SMS and gets an auto-response, you’ve burned the relationship. Someone needs to be monitoring that inbox.
What to send
Appointment reminders 24 hours out: open rate near-universal, cancellation rate drops 20–40% depending on your industry. This alone pays for any SMS tool you’re using.
Rebooking prompts 48 hours after a visit: “Great seeing you yesterday — when would you like to come back?” Feels human, converts well, and surfaces before the gap grows.
Occasional useful tips related to your service: a dental practice sending one tip per month about home care; a personal trainer sending a meal-prep idea the week before a big event. These build goodwill. They are not every week.
What not to send
Discount announcements. Promotions. “We’re running a special.” These train your subscribers to wait for discounts instead of paying full price, and they attract exactly the customers you don’t want more of.
What you should see
If you implement appointment reminders and one rebooking prompt, expect a 15–25% reduction in no-shows and a 10–15% lift in rebooking rate within ninety days. The tip content doesn’t move those metrics — it moves retention over a longer horizon.
