Description: When an admin or staff member reschedules a customer’s appointment, the system should automatically send an email notification to the customer with the updated appointment details (date, time, service, staff member if applicable). Requirements: Email should include both the original appointment details and the new rescheduled details for clarity. Email template should be customizable in the admin panel. Email should be triggered instantly after rescheduling. Option to toggle this feature on/off in settings. Benefit: This ensures customers are always informed of changes to their bookings, reducing no-shows and miscommunication.
