How to Manage Private Events
Some events are meant to be private based on your business needs.
Limit the access of those who can attend your meeting, think tank, or conference. Make your event private, by selecting the option “ Only allow guest registration” for the desired attendee types. This way, only those (the lucky ones) who are on your list will receive your invitation emails and will be able to register.
NOTE: If you select the "Only allow guest registration" option, please make sure that you import a list of guests.
To import a list of guests, please refer to the article How to Import a List of Guest.
