Three messages, one calendar, no per-message bill
It reads your calendar and sends at the intervals that actually move the number — a week out, the day before, the morning of — on WhatsApp, SMS or email, whichever that person replies on.
- WhatsApp first, because that is where the message gets read
- A reply of "yes" or "no" writes back to your calendar
- Cadence per appointment type — a cleaning and a surgery are not the same lead time
- 600 messages a month included, not metered
Expected launch price $39 a month, one calendar, messages included.
What the alternatives cost and what they assume
Published pricing, August 2026, converted where necessary.
| Option | Entry price | Primary channel | What you also have to adopt |
|---|---|---|---|
| No-Show Reminders | $39/mo, messages included | Nothing — it reads your existing calendar | |
| GoReminders | from ~$25/mo by volume | SMS and email | Nothing, and it is a good product |
| Apptoto | ~$39/mo, 450 credits | SMS and email | A credit budget you now have to think about |
| Booking suite (Trinks, Simples Agenda) | varies by plan | SMS and WhatsApp | Their scheduling, their payments, their client app |
| Twilio or Zenvia plus glue | per message | Anything you build | A developer, permanently |
| The front desk phoning | staff time | Voice | Nothing, and it costs more than all of the above |
GoReminders is the one to beat and this table is not going to pretend otherwise. The bet is narrow: WhatsApp as the first channel rather than the third, and a flat price instead of a credit balance.
Why the channel is the whole product
Every product in this category sends reminders. The difference between the ones that work and the ones that do not is almost entirely whether the message is read, and that is a question about the country you are in rather than about the software.
In Brazil and across Spanish-speaking Latin America, an SMS from an unknown number is close to invisible and an email is worse. WhatsApp is where appointment confirmations already happen, by hand, typed by a receptionist between calls. The American incumbents treat it as an add-on channel because their home market does not need it.
That is the entire thesis. Not a better algorithm, not smarter timing — the correct channel first, priced flat so a clinic sending four hundred messages a month is not doing arithmetic before it sends them.
The arithmetic, unglamorously
- expected launch price a month, messages included — $25 held for founder-tier signups
- $39
- recovered appointment a month at a $90 ticket more than covers it
- 1
- the range published no-show studies report by sector, which is why an average is useless to you
- 5–30%
One calendar, no contract

The cadence that the evidence supports
Three touchpoints, each doing a different job. More than three annoys people; fewer than three leaves the main one uncovered.
- 1
One week out: the reschedule window
This message exists so the person who already knows they cannot come tells you now, while the slot is still fillable.
It is the only reminder that recovers revenue rather than merely preventing loss, and it is the one most often skipped because it feels too early.
- 2
The day before: the actual reminder
The workhorse. Most no-shows are forgetting, and this is the message that addresses forgetting.
Afternoon rather than morning. A message that arrives at 9am on a working day is read in a queue of other things and remembered less well than one that arrives at 4pm.
- 3
The morning of: the last chance
Short, with the address and a way to say no. This one turns a silent absence into a phone call two hours ahead.
Two hours is not enough to fill the slot from a waiting list in most practices, but it is enough to stop a clinician standing in an empty room.
Three is not a magic number and nobody should present it as one. It is the point past which the marginal message stops changing behaviour and starts eroding goodwill, and where that point sits varies by how often you see the same person.
What it would cost
One calendar, flat, no contract. The message allowance is generous on purpose — metering is what makes this category's advertised prices meaningless.
Expected launch price
$39per month
Founder price$25 per month
One calendar, unlimited appointments, messages included up to 600 a month. Included rather than metered, because a per-message price is how the advertised number in this category stops predicting the invoice.
This product does not exist yet. The number above is the price we expect to launch at, not a commitment. If the waitlist says it is wrong, it changes.
What the price covers
- Up to 600 messages a month, included in the price
- WhatsApp, SMS and email, chosen per patient
- Cadence rules per appointment type
- Confirmations written back to your calendar
- A weekly note: who confirmed, who went silent, who did not show
- Message templates in English, Portuguese and Spanish, editable
What it does not cover
- Booking. Your calendar stays where it is, and this reads it.
- Payments, deposits, and no-show fee collection.
- Automatic waiting-list backfill. Genuinely useful, genuinely a different product.
- Any claim about how much your no-show rate will fall.
Above 600 messages, overage at cost with the rate shown before you cross it. Founder price holds while the account stays open.
Objections
- Our patients confirm by phone and it works.
- It does work, and it is the most expensive option in the table above. Two minutes a call including the unanswered ones, across sixty appointments a week, is a morning of somebody's time every week — usually the person who is also the first thing a patient sees when they walk in.
- WhatsApp requires template approval and that sounds like a headache.
- It is a headache, it is real, and it is the biggest operational risk in this product. Templates have to be submitted and approved before they can be sent outside a 24-hour window, and a rejection is a support ticket. The product's job is to absorb that; whether it can absorb it at $39 is the open question, and it is stated here rather than in a footnote.
- We already pay for a booking system that sends reminders.
- Then you have this covered and should not buy anything. The specific case this is for is a practice whose calendar is Google or a paper-adjacent system, where the booking suite would be a migration rather than a purchase.
- A reminder will not stop someone who never intended to come.
- Correct, and the week-out message is the one aimed at that person. It does not stop them missing the appointment; it gets them to say so while the slot can still be resold, which is a different and more valuable outcome.
