What does RSVP mean? Meaning, how to reply, and how to collect replies

RSVP means "please reply". It is short for the French phrase répondez s'il vous plaît, and when it appears on an invitation it means the host wants to know whether you are coming, ideally by the date they mention. That is the whole answer. The rest of this guide covers how to reply properly, what the common variations mean, and, if you are the one hosting, how to collect replies without chasing anyone.

Where the phrase comes from

RSVP is one of the few bits of French that survived intact in English etiquette. French was the language of polite society across much of Europe for a long time, so formal invitations borrowed its conventions, and the abbreviation stuck even as the full phrase fell out of use.

Strictly speaking, "please RSVP" says "please" twice, since the s'il vous plaît already means that. Nobody minds. "Please RSVP by 12 May" is normal English now, and clarity beats pedantry on an invitation.

The letters are always written as RSVP, in capitals, without full stops. As a verb it works like any other: you RSVP, you RSVP'd, and your host is waiting for people to RSVP.

What the common RSVP phrases mean

Invitations rarely stop at the four letters. These are the variations you will meet most often and what each one asks of you.

RSVP by [date]

The reply deadline. The host needs final numbers for a venue, a caterer or a seating plan, and this date is when they have promised those numbers to someone else. Reply before it, not on it, and certainly not after it.

Regrets only

Only reply if you cannot come. If the host hears nothing, they will count you in. It keeps the host's inbox quiet for casual events, but it also means a forgotten invitation turns into an unexpected guest, which is why larger or catered events tend to avoid it.

RSVP to [name, email or phone]

How the host wants to hear from you. Use that channel and not another one. A reply sent to the wrong person, or buried in a group chat, is easy to miss and may never reach the list.

Plus one, "and guest"

You may bring one person. Give their name when you reply so the host can add them properly. If the invitation names only you, it is for you alone, and the polite move is to ask before assuming.

RSVP card, RSVP link

The two ways to reply. A card comes with a formal paper invitation and goes back by post. A link opens an online RSVP page where you confirm, add companions and answer any questions in a minute or two.

How to RSVP as a guest

Replying well takes less than five minutes. Here is the short version.

1. Reply by the date, whatever your answer. A quick no is far more useful to the host than silence, and it is not rude to decline.
2. Reply for everyone named on the invitation. If it is addressed to you and your partner, say whether both of you are coming, not just you.
3. Use the method the host asked for. If there is a link, use the link. If there is a card, post the card.
4. Give the details they asked for. Meal choice, dietary needs, whether you are bringing children, your plus one's name. The host asks because they need to know.
5. Do not change your answer casually. If your plans genuinely change, tell the host straight away so they can adjust numbers.
6. Put it in your calendar the moment you say yes.

If you are writing the reply yourself, keep it simple. Something like "Thank you, we would love to come, both of us will be there. Anna is vegetarian" does the job. A decline is just as short: "Thank you for the invitation, sadly we can't make it. Have a wonderful evening." You do not owe anyone a detailed reason.

What hosts should put on the invitation

Most RSVP problems start on the invitation. Guests reply late because there was no date, reply to the wrong place because there was no clear channel, or reply with half the information because nobody asked for the rest. Four things fix nearly all of it.

• A reply deadline, as an actual date. "RSVP by 3 April" works. "Please let us know soon" does not. Pick the date by working back from when your venue or caterer needs numbers, then add a week of buffer.
• One way to reply. A single link, email address or phone number. Offering three channels means tracking three channels.
• The questions you need answered. Meal choice, dietary needs, children, plus ones. Ask on the invitation or the RSVP page, not in a follow-up a month later.
• Who is invited, by name. This is how you avoid uninvited plus ones without an awkward conversation.

If you are starting from a blank page, our invitation templates have the RSVP line and deadline already in place, so you only need to fill in the details.

How to collect RSVPs online

For a dinner with eight friends, a group message is fine. For anything bigger, replies arriving by text, email, phone and in person turn into a spreadsheet you maintain by hand, and the same three people still have not answered the week before.

An online RSVP page removes most of that work. Guests open a link, say yes or no, add their companions and answer your questions. Every reply lands in one list that updates as it comes in, so you always know your current headcount and who is still outstanding. Reminders go to the people who have not replied, not to everyone, and you can export the final list to CSV for the venue, the caterer or the place cards.

This is what GuestlistOnline's RSVP page does. You set up the event, add your custom questions and plus-one rules, send email invitations and reminders, and watch the live guest list fill up. The free plan covers one event with up to 50 guests, and there are no fees on free events. If you also want QR tickets and check-in at the door, that comes with the paid plans (Per Event at 19.99 euro one-off, or Pro at 29 euro per month). The platform runs in seven languages and is hosted in the EU.

Whichever tool you use, the principles are the same: one link, one list, reminders to the right people. We go into the setup step by step in how to collect RSVPs online.

What to do when guests do not reply

Some guests will not reply, however clear your invitation is. It is not usually a snub, they simply meant to and forgot. Plan for it rather than taking it personally.

• Send one reminder a few days before the deadline. Keep it friendly and short: "Quick reminder, we would love to know by Friday whether you can make it." One line, one link.
• After the deadline, go personal. A direct message or a call to the handful who are still silent gets answers that a third mass email will not.
• Decide what silence means, and tell people. For catered or ticketed events, say on the invitation that no reply by the deadline means no seat. Then stick to it.
• Keep a small buffer. Expect a few last-minute changes in both directions and let your numbers absorb them.

That is really all there is to it. RSVP means "please reply", replying well means doing it on time with the details asked for, and hosting well means making the reply so easy that nobody has an excuse not to.
