Once an order/appointment is created, a notification email is being sent to both merchant and customer including a calendar event file (.ics) to be imported to your calendar of choice.
Default reminders are set as event alerts which can be customized easily.
You can manage the email notifications in:
Sesami > Settings > Email confirmations and calendar events
We currently have an integration with google calendar and Sesami. For more information, check out our Google Calendar help page.
Currently, Sesami does not have any appointment reminders available for yourself or your clients. What you and your clients receive however is a booking confirmation email from Sesami with a calendar event file (.ics).
