Why my RSVP guests do not receive confirmation emails after they click "Yes" in the RSVP email and submit their registration?

If you invite your guests via RSVP, you will need to turn on and setup RSVP Confirmation before sending RSVP emails.

When RSVP Confirmation is On, the guests who click Yes in the RSVP email, complete and submit their registration will receive a confirmation email to confirm the registration.
