Automated appointment reminders reduce no-shows by up to 80%. When a client books a week in advance and receives no follow-up, life gets in the way. A single reminder sent 24 hours before — and another one hour before — is enough to cut most absences.

Why no-shows happen

Clients don't cancel out of malice. They forget, they get confused about the time, or they assume cancelling is complicated. Research across service businesses consistently shows that the gap between booking and appointment is the main risk factor. The longer the gap, the higher the no-show rate.

Manual reminders — a phone call the day before — work, but they eat 20–40 minutes of staff time per day and get skipped when the salon is busy. That's exactly when clients need reminding most.

The two-message sequence that works

You don't need a complex system. Two messages cover most cases:

  • 24 hours before: confirmation with the date, time, address, and a simple way to reschedule if needed.
  • 1 hour before: a short reminder. No action required — just a nudge.

Adding a post-visit message (sent 2 hours after the appointment ends) also increases rebooking rates, since the client is still thinking about the service.

Which channel to use

The best channel is the one your client already uses. For most service businesses in Europe and Latin America, that means WhatsApp or Telegram for the reminder and email for the confirmation. SMS works as a fallback.

Pronto sends reminders through all four channels — WhatsApp, Telegram, Viber, and email — automatically, without staff involvement. Each business connects its own credentials, so there's no per-message cost beyond what the platform charges (WhatsApp via Meta Cloud API is free within the 24-hour customer service window).

What to write in the reminder

Keep it short. The reminder is not a marketing message — it's a service. Three things are enough: the client's name, the appointment time, and where to go. Avoid promotional language in reminder messages; clients find it off-putting and it reduces open rates.

Setting it up in Pronto

In Settings → Notifications, connect your Telegram bot token or WhatsApp credentials. Reminders for 24h and 1h are enabled by default. You can adjust timing or disable specific channels per event type. The setup takes about five minutes during onboarding.

Frequently asked questions

How much does it cost to send appointment reminders via WhatsApp?

Using the Meta Cloud API, messages sent within a 24-hour window after a client contacts your business are free. For business-initiated messages like reminders, Meta requires pre-approved message templates (HSM). There is no per-message fee for the API itself — costs depend on Meta's conversation-based pricing, which varies by country.

Can I send reminders through Telegram for free?

Yes. The Telegram Bot API is completely free with no message limits. You connect your own bot token in Pronto settings, and all reminder messages are sent at zero cost.

What if a client hasn't connected to my Telegram or WhatsApp bot?

Pronto sends reminders through whichever channels the client has connected. If a client has only provided an email address, the reminder goes by email. You can set a fallback priority order in notification settings.
