1. Allow one booking per email address only - This restricts bookings to one booking per email address. If a customer attempts to create a second booking with the same email address as the first they will not be able to proceed to complete the booking.
2. Limit Sales to these addresses - If you are holding an event that is not open to all, you can provide a list of email addresses for us to check against. If the booker's email address is not on this list they will be prevented from completing their booking.
If you want to allow everyone at a particular organisation address to book, you can just list the domain (the part after the @ in the address, for example “bookitbee.com”). This list of email addresses remains private. If a booker does not match this list, they will be instructed to contact you.
These restrictions only apply to the person making the booking. If you are collecting individual attendee email addresses, those are not checked against this list.
