This setting determines when your attendees will be considered “confirmed registrations” and will be sent the confirmation email for your event. You can read a quick breakdown of when in the registration process each condition is met.
1) Person registers
This is the least restrictive setting. Anyone who successfully completes the registration form will be marked as “confirmed” and sent the confirmation email.
2) Person registers and email address is verified
This condition is met when an attendee has verified his or her email address. An email is sent to the email address the attendee uses to complete the registration form with a link he or she needs to click.
This condition can also be met if the event has a cost, payments are accepted, and the person completes his or her payment.
3) Person registers and completes payment (when applies)
If an event does not accept payments, anyone who successfully completes the registration form will be marked as “confirmed” and sent the confirmation email. Otherwise a person must complete payment for their registration to be considered “confirmed” and sent the confirmation email.
4) Manually marked as confirmed only
All registrations are initially marked as “not confirmed” until an administrator manually marks them as confirmed. The administrator can also send out a confirmation email from the WordPress dashboard.
