# Setting Up Time Intervals for Booking Reminder Automation

{% embed url="<https://youtu.be/Af36oTwuVsM>" %}

Timely reminders play a key role in reducing no-shows and keeping your customers engaged. With Mercuri CX, you can easily configure when these reminders are sent.

**Default Intervals:**

* A reminder is sent **24 hours (1 day)** before the appointment.
* Another reminder is sent **1 hour** before the appointment.

If preferred, you can remove one of these intervals, but at least one reminder must always be set up.

**Adding Custom Intervals:**

1. During automation setup, navigate to the Reminder Configuration section.
2. Click on “Add Another Reminder”.
3. Choose your preferred interval (e.g., 2 days before, 6 hours before, or 30 minutes before the appointment).

📌 **Note:** *The reminder may be delivered up to **10 minutes earlier or later** than the exact scheduled time.*

### Best Practices:

* Always set at least one reminder (mandatory).
* Avoid overwhelming customers with too many notifications; 2 to 3 well-timed reminders are often most effective.
* Consider your customer’s time zone when scheduling reminders.
