Navigate to Settings > Notifications
You'll notice you can set a threshold for receiving new appointment request and canceled appointment email notifications.
If you set them to 48 hours, you would receive a notification when a new or canceled appointment is scheduled to start within 48 hours of the request.
Trick: There Is No Limit!
There is no limit to the number of hours you can enter. If you want to be notified of every request or cancellation, just set the threshold to 1 Year or 8,760 hours 😎
Tip: Todo List
To cut down on email, start by setting a shorter threshold. To stay up to date on new requests, use the weekly schedule view as an approval todo list. Start by selecting the weekly schedule view. Next, select the pending (orange) filter. The result is a weekly todo list of approvals that need attention.
