Online wedding RSVP: how to get replies without chasing anyone

RSVP comes from the French répondez s'il vous plaît — "please reply". At a wedding today it means something very specific: knowing how many of you there are, what everyone eats and who needs a shuttle seat. In other words, the information the whole budget hangs on.

Why paper no longer works for this

There was a time when replying meant posting a card back. Nobody does that now: guests answer by WhatsApp, by phone, or when you bump into them. The result is that the list lives in someone's head — and that someone reconstructs it at midnight before sending it to the caterer.

An online RSVP solves exactly that: the guest replies from their phone in under a minute and the answer lands already structured in a dashboard.

Which questions earn their place

Every extra question lowers your response rate. These are worth it:

• Attendance: yes / no.
• Full name of each attendee, not just "and guest" — that is what you will use for the seating plan.
• Plus-ones and children, with ages if there is a children's menu.
• Allergies and dietary needs. Your caterer will ask for them anyway.
• Shuttle: which stop, what time. If there is transport, this question saves you two weeks of messages.
• The song that cannot be missed: optional, but the most answered of all — and your playlist writes itself.

What to leave out: postal address, ID numbers, long open-ended questions.

Timing

• Save the date: 8–12 months ahead if guests are travelling.
• Invitation with RSVP: 3–5 months ahead.
• RSVP deadline: 4–6 weeks before the wedding, written down and visible.
• Reminder: one week before the deadline, only to those who have not replied.

How to actually get replies

Three things move the needle more than anything else:

1. One minute to answer, straight from a phone. The moment sign-up is required, the rate collapses.
2. A personal message when you share the link, not a forward into a sixty-person group.
3. A concrete deadline with a reason: "we need to confirm the caterer on 1 August" works far better than "whenever you can".

With that, 95% replies with zero follow-up calls is entirely normal.

And afterwards: what to do with the data

At least three vendors need the final list, and each wants something different:

• Caterer: final headcount, menu split and the allergy list with names
• Transport: seats per stop and per departure, out and back
• DJ: the requested songs, without duplicates
• Venue/styling: table count and who sits with whom

With an exportable dashboard you filter and send each of them only their part as an Excel file. No retyping, no copying out of WhatsApp, no 3 am spreadsheet.

The RSVP wording that works best

Phrasing moves the reply rate more than you would think:

❌ Weak	✅ Works
"Let us know when you can"	"Please reply by 1 August — that is when we confirm the catering"
"RSVP requested"	"One minute, and it helps us enormously"
"State any intolerances"	"Any allergies? It goes straight to the caterer as written"
"Number of guests"	"Bringing someone? Give us their name for the seating plan"

The rule: always give the reason. "We close the catering on the 1st" turns a vague request into a deadline with a consequence.

What to do about non-responders

There is always a 10–15% who do not reply first time. The protocol that works best for us:

1. 10 days before the deadline: a general reminder in the group, friendly, singling out nobody.
2. On the deadline: an individual message only to those outstanding. Personal, not forwarded.
3. Three days later: phone them. By now it is usually older relatives or people with genuine questions.
4. A week later: no reply counts as "not attending" — and you say so: "We are marking you as unable to come; if that changes, let us know before X."

That last step is the hardest and the most useful: without it, the list never closes.

How many actually confirm

Rough figures from the weddings we work on:

Moment	Share of the list confirmed
First 48 hours	35–50%
First week	60–70%
By the deadline	85–90%
After individual reminders	95–98%

If you are under 50% after a week, the problem is almost never the guests: usually the link got lost in a big group chat, or the form asks for too much.

Frequently asked questions

When exactly should the deadline be? Four to six weeks out. Fewer than four does not leave time to close the catering; more than six and people park it.

Menu choice in the RSVP or later? If there is a menu choice, in the same form. A second round of emails loses half the replies.

What about people who confirm and then do not come? It always happens — budget for 2–3%. That is why you should confirm numbers with the caterer a few days after the deadline, not on the day itself.

Can I see who has opened the invitation? On your own website you can see aggregate visits. Knowing whether a specific person opened it is a privacy question, and we do not do it.
