If event space is limited, you may want to constrain RSVPs by limiting them to one RSVP per email address. This setting is enabled by default on all new event pages.

To update it:

1. Go to the Settings tab in your event page.

2. At the top of this screen, choose the Privacy sub-tab.

3. In the Registration options on the right, find "RSVP Limit Once Per Email" and check or uncheck the box. This will restrict guests from registering for your event more than one time with the same email address.

Remember to save your changes!

If space is very limited, we recommend sorting your RSVPs by First Name and Last Name and checking to ensure guests didn't use multiple email addresses to RSVP.
