3 Emails. Zero Manual Work.
Each email is triggered at the exact right time — calculated from the appointment date and time you send via webhook.
Confirmation email
Sent the moment a booking arrives. Includes appointment date, time, service, and location. Reassures the client and sets expectations for upcoming reminders.
24-hour reminder
Sent the day before the appointment. Reminds the client of the details and includes a reschedule link if needed — giving you time to fill the slot rather than absorbing the no-show.
1-hour reminder
The single most effective no-show reducer. Sent 60 minutes before the appointment with a short, friendly message. Studies show this alone reduces no-show rates by 30–50% on top of the 24h reminder.
Works With Your Booking System
Any tool that can send a webhook — which is most modern booking platforms.
Why Service Businesses Love This
Consultants, salons, coaches, clinics, and any business that runs on appointments — this automation covers the most common scheduling pain point.
Eliminates no-show revenue loss
Businesses using automated reminders report 50–80% fewer no-shows. At an average appointment value of $150, recovering even one no-show per month more than pays for this template.
Precise timing via Wait nodes
n8n's Wait Until Specific Time feature pauses execution until the exact moment each reminder is due — not a cron job, not an approximate schedule. Reminders fire at the right minute.
Google Sheets appointment log
Every booking is logged with client details, appointment time, service, and reminder status. Your entire appointment history is visible in one spreadsheet — no extra tools needed.
Fully customisable emails
All 3 email templates are editable inside the workflow nodes. Change the tone, add your address, include a Zoom link, or add cancellation policy — no coding needed.
Zero ongoing costs
Gmail sends via your existing Google account — no Twilio, no SendGrid, no per-email fees. The only cost is your n8n plan (free tier handles this easily).
Extensible with SMS
The setup guide includes an optional Twilio SMS extension. Add SMS reminders alongside email for less than $0.01 per message — particularly valuable for mobile-first clients.

Frequently Asked Questions
Everything you need to know before buying.
How does the appointment reminder automation work?
When a booking arrives via webhook, the workflow logs it to Google Sheets and sends a confirmation email instantly. Code nodes calculate the exact 24-hour and 1-hour reminder times. n8n's Wait Until Specific Time pauses execution until each reminder is due, then sends the email automatically — no cron jobs needed.
Which booking systems does this work with?
Any system that can POST to a webhook URL — Calendly, Acuity, Typeform, Tally, Google Forms (via Apps Script), Webflow, or custom forms. The setup guide includes field mapping for Calendly and Acuity specifically.
Does this work across time zones?
Yes, as long as appointment times are sent in the business's local timezone consistently. The workflow calculates reminder times relative to the appointment datetime — no time zone conversion needed if your booking system sends local times.
Can I add SMS reminders?
Yes. The setup guide includes an optional Twilio SMS extension. Add SMS nodes alongside the Gmail nodes for under $0.01 per message — particularly useful for clients who may miss email reminders.
Do I need n8n cloud or can I self-host?
Both work. n8n cloud free tier is recommended — it runs continuously so Wait nodes always fire on schedule, even days after the booking. Self-hosted works too but requires the server to stay online between booking and appointment time.
What happens if a client reschedules?
The workflow handles new bookings. If your booking system sends a reschedule webhook, a new execution starts with the updated time. To prevent old reminder executions firing, add an IF node that checks Sheets for a "Rescheduled" status — the setup guide covers this edge case.
