Reply-by date gone, or the venue full? Close the RSVP. The RSVP button disappears from your invitation, and every reply you’ve had stays put.
How to close it
In your dashboard, open the RSVP page of your invitation.
Click the menu (the three dots) next to the RSVP heading.
Choose Close the RSVP.
You close and reopen the RSVP in the same menu.
What changes
Guests no longer see the RSVP button. Your other buttons stay as they are.
In the list of all your invitations, the RSVP shows as Closed.
You can still view and download the list, and edit replies too.
Opening it again
Choose Open the RSVP in the same menu. Only one late cancellation by text or phone? No need to reopen anything. Just edit the reply yourself (Edit or delete an RSVP).
Change details reopens the RSVP. If you later click Save settings there while Enable RSVP is ticked, the RSVP is open again. Close it once more if so.
