A no-show costs more than the empty slot. Someone else could have had it, and the time you set aside is gone. A short text a day or two before is the cheapest fix most businesses have, and there’s good research on how well it works.
Reminders work. In a randomized trial at a pediatric clinic, patients who got a text reminder on top of the clinic’s usual voice message missed 23.5% of appointments. Patients who got only the voice message missed 38.1%.
Wording matters. A study of more than 160,000 patients at Clalit, Israel’s largest health system, tested nine versions of the same reminder. The generic one had a 21.1% no-show rate. The best one, which said that missing an appointment without cancelling holds up care for someone else who needs it, had 14.2%. Five of the eight new versions did better than the generic one.
Both studies were in health care, where no-shows are measured carefully. The same idea applies to a salon chair, a consultation, or a service visit: remind people, and tell them why cancelling ahead matters.

Keep each one short enough to read in a glance. Put the day and time near the start, and give one action, not three.
Ask for the customer’s okay to text when they book, and include a way to stop, like replying STOP. That’s good practice, and many texting services require it. Keep reminder texts about the appointment, and save promotions for customers who asked for them.
Most booking software can send reminders, so check yours first. What it often can’t do is read the replies, move the appointment when someone writes R, or offer the slot to the next person waiting. Reminders are one of the six add-ons on Foundry24’s Growth and Pro plans, and on their own they’re the kind of single task an automation handles, from $199 a month. When customers reply with questions, an AI agent can answer them.
Yes. In a randomized trial at a pediatric clinic, adding a text reminder to the usual voice reminder cut no-shows from 38.1% to 23.5%. In a study of more than 160,000 patients in Israel, the best-worded text cut no-shows from 21.1% to 14.2%.
Send a confirmation when the appointment is booked, a reminder a day or two before, and, for longer or costlier appointments, a short one the morning of.
The business name, the day and time, the address or how to join, and one easy way to confirm or reschedule. Asking people to cancel ahead so someone else can have the slot also helps.
Get the customer's okay to text when they book, and include a way to stop the messages. That's good practice, and many texting services require it.
