Your response method should match how you invite people and how your venue needs to count them.

Start with the guest list
If one invitation covers two adults and two children, the response should let the household confirm each name. A simple yes or no leaves the headcount uncertain.
Separate attendance from eligibility
Invitees may have different event lists. Confirm the eligible people and events first, then decide where guests can say yes, no or undecided.
Design the change process
Agree whether guests can edit online after submitting or must contact the planner. Set a deadline early enough to update the caterer and transport team.
Protect the data you collect
Ask for information you can act on. Decide who needs to see dietary notes and when to remove the RSVP records.
