Once you’ve sent your reply, you can’t change it yourself. The host can. So if your plans change, just let them know.
How to sort it out
- Contact the host the way you normally would: a message, a call, or a reply to the email the invitation came in.
- Say which name you used for your RSVP and what has changed: coming or not, or a different number of people.
- The host updates or removes your reply.
Why not just fill it in again?
You can, but then the host’s list shows two replies from you, the old one and the new one. That easily leads to counting mistakes. If you do submit again, mention in the personal message that this is your new answer.
Got the invitation by email? At the bottom of that email you’ll find the host’s email address for questions about the event.
