RSVP stands for *répondez s’il vous plaît* — “please reply.” It’s a simple request, but anyone who has hosted a party knows how often it goes unanswered. Hosts need numbers to buy food, set tables, book venues and plan seating. A prompt reply, either way, is a small gift to the person who invited you.

## The golden rules of replying

- **Reply quickly.** The Emily Post Institute advises [replying within a day or two of receiving an invitation](https://emilypost.com/advice/invitation-etiquette), and by the RSVP deadline at the latest.
- **Reply either way.** Unless the invitation says “regrets only,” the host needs your no as much as your yes.
- **Reply the way you were asked.** Use the response card, website, e-vite or phone number provided.
- **Reply only for those invited.** The names on the invitation are the guest list.
- **Keep your word.** A yes is a commitment the host is planning around.

## How to RSVP, by invitation type

| Invitation says or includes | How to reply |
|---|---|
| A response card | Fill it in and mail it back in the envelope provided, before the deadline. |
| “RSVP” with an address but no card | Send a short handwritten reply to the host at the return address. |
| “RSVP” with a phone number | Call and speak to the host, rather than relying only on voicemail. |
| An e-mail invitation | Reply to the e-mail. |
| An e-vite or wedding website | Use the site’s RSVP button. If you choose “maybe,” follow up with a firm answer. |
| A text or group chat | Reply directly to the host, not only in the group thread, so your answer doesn’t get lost. |
| “Regrets only” | Reply only if you can’t attend. Silence means yes. |
| No reply requested | A quick note or call letting the host know your plans is still courteous. |

How to reply to each kind of invitation

These methods follow the Emily Post Institute’s guidance on [how to RSVP](https://emilypost.com/advice/how-do-i-rsvp), including its reminder that if you pick “maybe” on an e-vite, you should come back with a final answer.

## Sample wording

> **Accepting**

> “Thank you so much for the invitation — Alex and I would be delighted to come to dinner on Saturday the 14th. Is there anything we can bring?”

> **Declining**

> “Thank you so much for thinking of me. I’m so sorry I can’t make it on the 14th — I’ll be out of town that weekend. I hope it’s a wonderful evening, and I’d love to catch up soon.”

> **Accepting with a dietary note**

> “We’d love to come, thank you! Just so you know, I’m vegetarian — please don’t make anything special; I’ll happily fill up on sides.”

You don’t owe a detailed reason for declining. “I have a conflict that evening” is complete and polite. Do avoid a vague reason that you then visibly contradict on social media.

## Plus-ones, partners and children

The invitation tells you who is invited. Read the envelope or message carefully:

- **Your name only:** you alone are invited. Don’t ask to bring a date.
- **Your name “and guest”:** you may bring someone. Tell the host whether you will, and give their name.
- **Your family’s names, or “the Kim family”:** children are included. If only adults are named, they aren’t.

Emily Post’s advice on asking to add people is blunt: [don’t ask](https://emilypost.com/advice/invitation-etiquette). If you have a houseguest that weekend, the gracious move is to decline and explain why; the host can then offer to include your guest if they wish.

## Changing your answer

### Acceptable

- Changing yes to no for illness, injury, a death in the family or an unavoidable work conflict
- Changing no to yes if it won’t disrupt the host’s plans (ask first)
- Telling the host as soon as you know, by phone if it’s close to the date

### Not acceptable

- Dropping out because a better invitation came along
- Simply not showing up
- Leaving a “maybe” unresolved until the day
- Turning up with someone who wasn’t invited

No-shows hurt more than hosts let on, and the problem isn’t limited to private parties. In a survey OpenTable reported in 2021, [30% of Americans said they had skipped a restaurant reservation in the past year](https://www.restaurantdive.com/news/opentable-launches-initiative-to-combat-diner-no-shows/602034/). Whether it’s a dinner table or a friend’s living room, someone planned and paid for your seat.

> **Cancelling after accepting**

> “I’m so sorry to do this — I’ve come down with a fever and won’t be able to come tonight. I was really looking forward to it. I hope it’s a lovely evening, and I’d love to see you soon.”

## For hosts: making it easy to reply

Hosts can reduce RSVP headaches with a clear invitation:

- Name exactly who is invited, including whether children or a guest are included.
- Give a specific reply-by date. Two weeks before the event is typical for larger gatherings.
- Offer one clear way to reply, such as a link, phone number or e-mail.
- Ask about allergies and dietary needs in the same message (see our guide to [hosting guests with dietary restrictions](https://courteo.us/dietary-restrictions-allergies/)).
- Keep a single list of replies. A free planner such as [Confetti](https://allthingsn.com/apps/confetti/) tracks guests, replies and to-dos in one place.
- Follow up kindly with anyone who hasn’t replied a few days before the deadline: “Just checking whether you’ll be able to join us on the 14th — no pressure either way!”

> **Why it matters**

> A fast, clear reply says, “I respect your planning.” It is the first courtesy a guest offers, long before they arrive at the door.

## Frequently asked questions

**What does RSVP stand for?**
RSVP comes from the French “répondez s’il vous plaît,” meaning “please reply.” It asks you to tell the host whether you will attend, yes or no.

**How soon should I RSVP?**
The Emily Post Institute recommends replying within a day or two of receiving an invitation, and no later than the RSVP date if one is given.

**What does “regrets only” mean?**
It means you only need to reply if you cannot attend. If the host doesn’t hear from you, they will expect you to come.

**Can I ask to bring a plus-one?**
Generally, no. An invitation is extended to the people named on it. If the invitation says “and guest,” say in your reply whether you’re bringing someone and give their name.

**Is it OK to change my RSVP from yes to no?**
Only for genuine reasons, such as illness, injury, a death in the family, or an unavoidable work conflict, and you should tell the host right away, ideally by phone. Dropping out for a better offer is a serious breach of etiquette.
