You can add external attendees to your Event without requiring them to acquire an Event ticket. This allows you to add non-members into an Event, in case you want to invite external speakers or add more attendees to your Event for free. To do this:

1. Go to your Event and click Event Details at the top.
2. Under Guests, click the icon in the top right and select Add External RSVPs.
3. Enter the email addresses you want to invite, separated by commas or line breaks, and click Send. Each person gets an invitation email and can attend without a ticket.
