By logging into WordPress, your customers can view their past and upcoming bookings right on your site, and even be able to cancel them right then and there (optional).
In Pages > All Pages, click on "Edit" right below the page where you want to add the list of bookings to.
Click on the "Add Bookly appointments list" button.
You'll be offered to check the columns you want to be added to the table, including the "Cancel" button, which will cancel an appointment at one click of a button and bring down your no-show count.
Notifications – a good way to keep clients in the loop.
