Thank you for posting! I noticed on your account that you have your RSVP's going to a linked email address. Did you know about our EventSpot feature? We offer Eventspot as a professional way to promote and manage any kind of event you may be running. You can create customized invitations, accept registrations and also process payments if your event has any fees involved. I would suggest taking a look at this EventSpot FAQ to read more about it: EventSpot Features.
Since you do ask your readers to RSVP to an email address you mentioned, I noticed the email address is set as a clickable link. When I clicked on this link, a completely different email address populated under the To address field and not the email address you have typed out in your email. So that could also be why you may or may not be receiving these emails. Your replies would go directly to the inbox of the email address that you provided if a reader were to click on this link to RSVP. We would not have a way to see how many replied, who replied or where these went unfortunately. Here's an FAQ on how you can add or edit the mailto link: Add a mailto link to an email.
Let us know if you have any additional questions!
