How to RSVP
How do you RSVP to an invitation?
RSVP stands for the French phrase "répondez s'il vous plaît", which means "please reply". To RSVP, you tell the host whether you will come. You do it the way the invitation asks: by link, reply, call or card, and before the date it gives.
This guide is for guests. It shows how to accept, decline and ask about a plus-one, with short sample replies. If you are the host, see the event RSVP guide and the RSVP wording guide instead.

How to RSVP in five steps
Replying takes a minute. Doing it early helps the host most.
Find out how to reply
Look for a link, an email address, a phone number or a reply card. Use the method the host names, not another one.
Note the deadline
Look for a line such as "RSVP by June 1". Add that date to your calendar.
Check who is invited
The envelope or the form often shows the names. If a plus-one is not mentioned, do not assume one is welcome. Ask.
Reply with a clear yes or no
Give your name as the host knows it and say whether you will attend. Add any dietary needs if the host asks.
Tell the host if your plans change
If you said yes and cannot come, say so as soon as you know. The host may be counting seats.
What the common phrases mean
Invitations use a few short phrases. This table explains each one.
| Phrase | What it means | What to do |
|---|---|---|
| RSVP | Please reply, yes or no | Reply either way |
| RSVP by [date] | The host needs your answer by that day | Reply before the date |
| Regrets only | Reply only if you cannot come | Reply only to decline |
| RSVP to [name] | Send your reply to that person | Use the contact given |
| RSVP required | The host needs a count, often for a venue limit | Reply even if unsure, and update later |
What "regrets only" means
"Regrets only" means the host will assume you are coming unless you say you are not. You reply only if you must decline.
If you plan to come, you do not need to answer. Some guests still send a short yes to be safe. That is polite and never wrong. If you are unsure, reply.
Sample replies you can copy
These are samples. Change the names and details to suit your event.
Sample RSVP replies
ACCEPT Hi [Host name], thank you for the invitation. I would be glad to attend on [date]. Please count me in. [Your name] DECLINE Hi [Host name], thank you for inviting me. I am sorry I cannot attend on [date]. I hope it goes well. [Your name] ACCEPT WITH A PLUS-ONE QUESTION Hi [Host name], I would love to come. Is it all right if I bring a guest? If not, I understand. [Your name] LATE CHANGE Hi [Host name], I am sorry to say my plans have changed and I can no longer attend. I wanted to tell you as early as I could. [Your name]
RSVP etiquette in short
A few habits make you an easy guest.
Reply on time
Even a late reply is better than none. Late answers are hard to plan around.
Answer for yourself only
Do not reply for someone else unless the host asked you to.
Do not add guests on your own
Ask first. The host may have a fixed number of seats.
Keep your answer
If you said yes, come, or tell the host early. If you said no, do not turn up without asking.
RSVPing to a work or large event
For a conference or workshop, the "RSVP" is often a registration form. You enter your details and may pick a ticket. A form can also ask about meals or access needs.
Eventdex's pages describe registration forms with questions per order or per attendee, and waitlists for a ticket. If a ticket is full and a waitlist is offered, join it. See how to register for an event for the full process.

FAQ
How to RSVP: common questions
What does RSVP mean?
It comes from the French "répondez s'il vous plaît", meaning "please reply". The host wants to know whether you will come.
What does regrets only mean?
Reply only if you cannot attend. The host will assume everyone else is coming.
What if I miss the RSVP date?
Reply anyway and apologize briefly. The host may still have room, and an answer is better than silence.
Can I bring a plus-one?
Only if the invitation says so or the host agrees. Ask the host before you add anyone.
What does RSVP mean in a text?
The same thing: please let me know if you are coming. A short reply of yes or no is enough.
