Registration, ticket and waitlist forms include settings that control how guests are added to your event. Use them to manage duplicate entries or limit who can register.
Guest Creation Options
Each form can use one of the following options:
Always Create a New Guest
Every submission creates a new guest, even if the email address matches an existing guest.
Use this option if you expect several submissions from the same email address.
Prevent Creating Duplicates
If a guest with the same email address is already in the event, the registration or ticket is saved to that guest.
Best when guests may register more than once or buy more tickets later.
Guests are matched by email address.
Restrict to Existing Guests
Only guests already in the event can register.
If the email address doesn't match an existing guest, the registration is blocked.
Useful when:
Ticket sales are limited to guests already imported into your event.
You send invitations through another email system and want to limit a public form to imported guests.
Note: This option works like RSVP Forms, but it doesn't require Diobox email invitations. You can share one public link and still limit who registers.
How to Configure Guest Creation Settings
Guest Creation Settings are part of the form's attributes. Set them when you create a form in the New Form window, or change them later:
1. Open your form.
2. Click More → Edit Attributes.
3. Under Guest Creation Settings, select Always create a new guest, Prevent creating duplicates or Restrict to existing guests.
4. Select the desired option.
Guest Experience
The form looks the same to guests. If Restrict to existing guests is selected and the email address isn't found, this error appears after the guest submits the form:
That email isn't on the guest list for this event. Please contact the event organizer.
With Prevent creating duplicates or Restrict to existing guests, each submission is matched to a single guest. Max per Submission (or Max per Order for ticket forms) is automatically set to 1 and locked, so every registration is checked against your guest list.
