I hope this does not ruffle any feathers, but I know many people who we are inviting to our wedding don't normally RSVP. What is a nice way to word asking them to on the invitation. I have a QR code on the back of the invitation for our wedding site, and for now, put "...to respectfully RSVP". Is that appropriate? If not, what would be, to let them know we are serious about RSVPing. Please don't say that they should know or anything. I just want answers to my questions. TIA.
