The right reminder at the right time can cut your no-show rate in half. But what makes a great reminder? Let's break it down.

When to Send Reminders

The most effective reminder schedule uses two touchpoints:

24 hours before — gives clients time to prepare or reschedule
1-2 hours before — a same-day nudge that keeps the appointment top of mind

SMS Reminder Templates

SMS has a 98% open rate — making it the most effective channel for reminders.

24-Hour Reminder

Hi ! Just a reminder that you have a appointment tomorrow at with . Reply CHANGE to reschedule or CANCEL to cancel. —

2-Hour Reminder

Hi , your at is coming up at today. See you soon! Need to change? Reply CHANGE.

After No-Show

Hi , we missed you at your appointment today. Would you like to reschedule? Book again at . —

Email Reminder Templates

Email reminders work best alongside SMS, providing more detail and context.

Confirmation Email (at booking)

Subject: Your appointment is confirmed

Include:

Service name and duration
Date, time, and timezone
Staff member name
Location or video call link
Cancellation/reschedule link
What to bring or prepare

24-Hour Reminder Email

Subject: See you tomorrow, !

Keep it brief with key details and a prominent reschedule button.

Best Practices

Keep it short — especially for SMS. Include only essential info
Personalize — use the client's name and specific appointment details
Include an action — make it easy to confirm, reschedule, or cancel
Be friendly — reminders should feel helpful, not pushy
Test timing — experiment with send times to find what works for your audience

The ROI of Reminders

A typical service business losing 10% of revenue to no-shows can recover most of it by implementing automated reminders. At just $20 per missed appointment, a business with 100 monthly bookings recovers $200/month — far more than the cost of a reminder system.

Automated reminders aren't just about reducing no-shows. They make your business feel professional, organized, and client-focused.

With Slotsy, reminders are sent automatically — no extra work for your team. Set up once, and let the system handle the rest.
