Wedding RSVP: what message to send, and how to follow up without offending

The RSVP is the reply you expect from each guest: 'I will come', 'I will not come', and how many people will accompany them. Without it, it's impossible to confirm a headcount with the caterer, make the seating plan, or order guest favors. Yet some guests reply late, or not at all. It's almost never bad will: the message got lost, the RSVP deadline was unclear, or no one thought to reply for the whole family. Here’s how to ask, and follow up, without awkwardness.

Asking for the RSVP: the right timing and the right information

When to ask for an RSVP

The RSVP request is sent with the invitation, or just after. Set a deadline about six to eight weeks before the wedding: that's when the caterer and the venue will ask you for an almost final number. A date too close to the wedding puts you under pressure; a date too far away is easily forgotten.

What the message should say

An effective RSVP message fits in a few lines, but it should include:

• the first names of the invited people, to avoid misunderstandings about plus-ones and children;
• the response deadline, written out in full;
• the simplest possible way to reply;
• useful questions for planning: dietary requirements, need for a shuttle, accommodation.

Be clear about plus-ones from the start: our article on the 'plus one' and accompanying guests helps set the rule.

An example message

Hi Leïla, we're getting married on Saturday, June 12 in Lyon and we'd be very happy to have you and Karim with us. Can you let us know before April 30 whether you'll be there? Everything is on our site, with the RSVP form: [link]. See you soon, Sarah and Yanis

The tone depends on your families: more formal for older relatives, lighter for friends. The important thing is that the guest understands at a glance what you expect from them, and by when.

Choosing the channel: WhatsApp, SMS or email

WhatsApp and SMS for most guests

A message to the phone is read almost immediately. It's the most effective channel for the majority of guests, especially close family and friends. A personalized link to an RSVP form avoids endless exchanges ('we'll be three, or maybe four...').

Email and paper for some guests

Some guests, often older relatives or professional contacts, prefer email or a paper card. Nothing prevents mixing channels: the essential thing is that all replies arrive in the same place. For the invitation card itself, see the essential information for the invitation card.

One place for all RSVPs

The trap is having replies scattered: three via WhatsApp, two by phone to your mother, one on a sticky note. Note each reply as soon as it arrives, in a single list. A wedding website with online RSVP does this work for you: each guest replies for themselves and their household, and the list updates itself.

Following up with guests who haven't replied

Best times to follow up

A first gentle follow-up one week before the deadline. A second, more direct, a few days later. Beyond that, a phone call is often simpler than a third message. Reminders at 60, 30, 14 and 7 days before the wedding are good checkpoints to check your status.

An example follow-up

Hey Thomas! We're finalizing the guest numbers with the caterer this week: can you tell us if you'll be there on June 12? The form takes a minute: [link]. Thanks, hugs.

Giving a concrete reason ('we're finalizing with the caterer') works better than a blunt reminder. Avoid reproaches: a guest who hasn't replied has often simply forgotten.

Delegating part of the follow-ups

For extended family, a parent or a witness often knows people's habits better. Give them a precise list of names, and ask them to record the replies in the same place as yours.

Mistakes that delay responses

• A missing deadline or one buried in a long message;
• a form that requires creating an account, or asks too many questions;
• an invitation addressed to "the family" without specifying who is invited;
• follow-ups sent to everyone, including those who have already replied.

The last point annoys quickly: only follow up with guests who haven't replied. An up-to-date list lets you know exactly who to contact, and to send each person a personal message rather than a collective reminder.

After the RSVPs

Thanking those who replied quickly

A small note to those who replied in the first days is always appreciated, and encourages others to do the same. For those who can't attend, a warm message shows you understand: a 'we'll think of you that day' is better than silence.

Confirming the numbers with vendors

Once the deadline has passed, count the attendees and absentees, and give the caterer a rounded number according to what your contract provides. Keep a small margin for late replies. If you don't have a caterer yet, compare the wedding caterers near you.

Moving on to the seating plan

The RSVPs give you the final list of attendees: it's the starting point for the seating plan. Our simple method for seating your guests takes over from there.

Frequently asked questions

How long before the wedding should you ask for RSVPs?

Set the deadline six to eight weeks before the wedding. This leaves time to follow up and to confirm the headcount with the caterer and the venue.

What to do if a guest never replies?

After two written follow-ups, call them. If there's no reply by the date you must confirm with the caterer, count them as absent and politely let them know their place is not reserved.

Should you ask about allergies in the RSVP?

Yes: it's the ideal moment. A simple question ('any allergies or special diet?') avoids having to call each guest afterwards, and your caterer will have the information in time.

Can you ask for an RSVP via WhatsApp?

Yes, it's often the most effective. Send a link to a form rather than waiting for a message reply: you keep all answers in the same place.
