Every couple is told that some guests will not RSVP. Everyone nods. Then the deadline passes, a quarter of the list has said nothing at all, the caterer wants numbers, and three weeks disappear into text messages.
It is entirely predictable, so it can be planned for.
The timings that work
- Save the dates: six to twelve months out. Only worth sending if your date is in peak season, involves travel, or falls near a holiday. Otherwise the invitation is enough.
- Invitations: around three months before. Earlier for a destination wedding or anything requiring flights.
- RSVP deadline: six to eight weeks before the wedding.
That deadline is the number that matters, and it should be set by working backwards from your caterer's final-numbers date, not chosen because it sounds about right. Ask the venue when they need confirmed numbers, then set your RSVP deadline at least three weeks before that. Those three weeks are your chasing window, and you will use all of them.
What the invitation has to carry
The design is the fun part. The information is the part that stops your phone ringing for a month.
- Who is invited, by name. This is how you handle plus-ones and children without a separate awkward conversation. "Sarah and James" means Sarah and James. It does not mean their three children, and naming them is the kindest way to say so.
- Date, start time, and full address with a postcode that works in a satnav. Rural venues frequently have a postcode that drops people in the wrong lane.
- What is happening and when. Ceremony only, all day, evening only. Guests need to know whether they are being fed.
- Dress code, in plain words. "Lounge suits" means nothing to a lot of people. "Suits and dresses, and the ceremony is on grass" tells them what to wear and what shoes to bring.
- The RSVP deadline and exactly how to reply. One method, clearly stated.
- Where to find everything else — a website address for travel, parking, accommodation, gifts and the rest.
Everything that is not one of those belongs on the website. An invitation trying to carry accommodation options is an invitation nobody reads.
Make replying take ten seconds
The single biggest lever on reply rates is friction. A card that must be filled in, put in an envelope, stamped and posted is four opportunities to put it down. A link that takes one tap on the phone that is already in their hand is not.
Online RSVPs typically arrive faster and in higher numbers, and they let you collect dietary requirements and song requests at the same time without a second round of asking. If you love the paper card — and plenty do, it is part of the pleasure of it — include one, but put the link on it too and let people choose.
Whatever you use, make sure it captures the things you will otherwise have to ask for separately: dietary needs, allergies, and whether they are coming to the evening as well.
Chasing, without losing your mind
Assume from the start that roughly a quarter will not reply by the deadline. It is not rudeness; it is a card on a fridge behind a school letter.
A system that works:
- One gentle reminder a week before the deadline, to everyone outstanding. A message, not a phone call. Plenty will reply within the hour, embarrassed.
- Split the remainder between you after the deadline, by side of the family. You chase yours, they chase theirs. Nobody should be texting their partner's second cousin.
- Delegate the last few. Your parents almost certainly have a phone number and a better relationship with the four remaining relatives than you do. Ask them.
- Set a genuine final date and hold it. "We have to give numbers on Friday, so we'll assume you can't make it if we haven't heard" is polite, honest, and remarkably effective.
That last line does the heavy lifting, and it is not rude. A caterer needs a number, and people respond to a real deadline in a way they never respond to a soft one.
The bit nobody mentions
Some of the people who do not reply are not disorganised. They are working out whether they can afford it, whether they can get the time off, or whether they can face the journey.
If someone is clearly hesitating, a short message that leaves an exit — "no pressure at all if it doesn't work, we'd just love to know either way" — is worth more than a third reminder. You will get a straight answer, and they will be grateful for the way you asked.
