This video walks you through how to make the Email field optional in the BookingPress booking form. By default, the Email field is set as required because BookingPress needs the email address to create a WordPress user. First of all, go to BookingPress → Customize → Custom Fields, where you’ll see that the required option for the Email field cannot be disabled.
To make it optional, go to BookingPress → Settings → Customers and disable the “Create WordPress user upon appointment booking” option. After this, you can go back to the Custom Fields section and disable the required option for the Email field. All in all, the video shows how you can make the Email field optional in your BookingPress booking form.
