5 SMS Templates That Actually Get Patients to Show Up

You’ve tried calling. Twice. The patient doesn’t pick up. But send them a text and they reply in four minutes.

This isn’t anecdotal — it’s consistent across every specialist practice we’ve worked with. Phone calls go to voicemail. Emails sit unread. SMS gets a response rate north of 90%, usually within minutes. For specialist practices trying to book patients, confirm appointments, and reduce no-shows, text messaging isn’t a nice-to-have. It’s the most effective communication channel you have.

Here are five SMS templates you can start using immediately. Each one is written to fit within a single SMS segment (160 characters) where possible, includes the required opt-out text, and covers a specific moment in the patient journey.

Template 1: Referral received confirmation

When to send: Same day the referral arrives at your practice.

Why it matters: The patient’s GP has told them “I’m sending a referral to Dr Smith.” The patient waits. Hears nothing. Calls the GP. The GP calls you. Everyone’s time is wasted. A same-day SMS confirming receipt eliminates this entire chain of follow-up calls.

Hi [First Name], your referral to [Practice Name] has been received. We'll be in touch within [X] business days to arrange your appointment. Reply STOP to opt out.

Character count: ~175 (2 segments). Worth it — this single message prevents the most common referral complaint.

Template 2: Appointment offer

When to send: When you’re ready to book the patient in.

Why it matters: Calling a patient to offer appointment times is a minimum two-attempt process. They’re at work, they’re driving, they can’t talk. An SMS lets them respond when it suits them, and your front desk isn’t tied up leaving voicemails.

Hi [First Name], we have an appointment available with [Dr Name] on [Date] at [Time]. Please reply YES to confirm or call us on [Phone] to discuss. Reply STOP to opt out.

Character count: ~190 (2 segments). You can trim by removing “please” and shortening the practice phone number if needed.

Tip: If your practice offers online booking, replace the phone number with a short link. Fewer calls for your team, faster booking for the patient.

Template 3: Appointment reminder (48 hours before)

When to send: Two business days before the appointment.

Why it matters: No-show rates in specialist practices typically sit between 10-20%. A well-timed reminder cuts that by roughly half. Two days gives the patient enough time to rearrange if they need to — and gives your team enough time to fill the slot if they cancel.

Reminder: You have an appointment with [Dr Name] at [Practice Name] on [Date] at [Time]. Please call [Phone] if you need to reschedule. Reply STOP to opt out.

Character count: ~175 (2 segments).

Tip: Don’t send reminders on the morning of the appointment. By then it’s too late for the patient to rearrange, and too late for you to fill a cancelled slot.

Template 4: No-show follow-up

When to send: Same day as the missed appointment, ideally within 2 hours of the scheduled time.

Why it matters: Patients miss appointments for all sorts of reasons — they forgot, they were unwell, they couldn’t get there. Most of them feel awkward about it and won’t call you. A non-judgemental follow-up text makes it easy for them to rebook without the embarrassment of a phone call.

Hi [First Name], we noticed you weren't able to make your appointment today. No worries — please call [Phone] or reply to this message to rebook. Reply STOP to opt out.

Character count: ~185 (2 segments).

What not to do: Don’t mention fees, penalties, or “failure to attend” language in an SMS. If your practice charges for no-shows, handle that in a separate phone call or letter. The goal of this message is rebooking, not billing.

Template 5: Re-engagement (14+ days no response)

When to send: When a patient hasn’t responded to your appointment offer or follow-up for more than 14 days.

Why it matters: These are your “ghosted” patients — referral received, attempts to contact made, no response. They represent real revenue sitting idle and, more importantly, a patient who may still need care. A single re-engagement text often breaks the silence.

Hi [First Name], we've been trying to reach you regarding your referral to [Practice Name]. We'd love to help — please call [Phone] when you're ready. Reply STOP to opt out.

Character count: ~180 (2 segments).

Timing matters: Send this during business hours on a Tuesday, Wednesday, or Thursday. Monday messages get lost in the start-of-week rush. Friday messages get ignored over the weekend. If there’s still no response after this message, it’s time for a final attempt by letter or phone — and then to update the referral status accordingly.

Australian compliance: what you need to know

SMS to patients isn’t unregulated. The Spam Act 2003 and ACMA rules apply. Here’s what you need to have in place:

Consent is required. You need the patient’s consent before sending them an SMS. This can be obtained as part of your intake process — a simple checkbox or verbal confirmation that you can contact them by text. If the patient has provided their mobile number on a referral or intake form and hasn’t opted out, implied consent generally applies for appointment-related messages, but explicit consent is always safer.

Every message must include an opt-out. “Reply STOP to opt out” is the standard. Your system needs to actually process STOP replies and suppress future messages to that number. SimpleRef handles this automatically — STOP replies are processed in real time and the patient’s record is flagged.

Keep it clinical, not promotional. Appointment confirmations, reminders, and follow-ups are transactional messages. Marketing messages (“We’re now offering a new service!”) have stricter consent requirements. Stick to operational communication and you’ll stay well within the rules.

Character counts matter for billing. A standard SMS segment is 160 characters. Messages longer than that are split into multiple segments and billed accordingly. Most of the templates above are two segments — that’s fine. Just be aware that a 161-character message costs twice as much as a 160-character one.

Putting it into practice

These five messages cover 90% of the patient communication a specialist practice needs. The referral confirmation builds trust on day one. The appointment offer and reminder reduce admin time. The no-show follow-up recovers lost bookings. The re-engagement text catches patients who’ve slipped through the cracks.

You can send these manually — your front desk can copy-paste them from a shared document. But if you’re sending more than a handful a week, automation saves significant time. SimpleRef’s SMS module lets you trigger these templates at each stage of the referral pipeline, with personalisation filled in automatically. You can check what’s included in each plan to see if it fits your practice.

Start with template 1. Send a same-day confirmation to every new referral for one week. Watch what happens to your inbound “has my referral been received?” calls. That’s usually all the evidence a practice needs.
