Can I ask questions to guests after they have submitted their RSVP?
All custom RSVP questions are added to the RSVP form. But if you need to gather more information after your guests have already submitted their response – you can do that too! Simply add a new question to the RSVP form and let guests know that they need to return to fill out the new questions.
When returning to the RSVP form, guests will have the option to start over, removing all previous answers they have given, or updating only the missing information. Usually, if you just want the answers to new questions, they should select the 'missing information' option.
