This feature is available for the following CRMs: InterAction, OnePlace and Dynamics as well as for Standalone lists.

When registering a new attendee for an event, you can add them to the guest list without inserting their email address, at the point of arrival. The Events App will store the guest's information until you "Close" the event, at which point you must add email addresses for these walk-ins before sending them to your CRM.

To use this feature, please contact your Client Success Manager, who can enable it at "Admin.System.Events. Display Walk-Ins Without Email Option".

Once enabled, you will be prompted when closing the event, to fill in the missing email addresses before the event is closed.  Once closed, the data from the event will be sent back to your CRM.

Please note, when using this feature, an email address is required before the contact will save back to your list.
