Picture this: you’ve sent 80 wedding invitations, each with a nice reply card and a stamped return envelope. Three weeks later, 40 cards have come back. For the other 40 people you have to chase. Via WhatsApp, phone, email. Aunt Brigitte lost the card, your cousin forgot to post it, three replies are utterly illegible.

Sounds exhausting? It is. That’s why RSVPs today are almost always digital.

What does RSVP mean anyway?

RSVP is French (“Répondez s’il vous plaît”) and means “please reply”. On a wedding invitation: let us know whether you’re coming, and by when.

Classically this happens by reply card in the invitation set. Modern: by QR code, link or online form.

Why digital RSVPs simply work better

1. Answers come back faster

Filling out a card, stuffing the envelope, posting it, that often takes weeks, because it’s not something you “just quickly do”. A QR code is scanned, a form filled, done. Most digital RSVPs come in within the first two weeks. Paper cards spread answers over two to three months.

2. You get more information

With a reply card you usually only ask “Coming? Yes/No”. Online you can also ask:

Meal preferences (vegetarian, vegan, gluten-free, allergies)
Accommodation (“Do you need a room in the hotel block?”)
Song requests for the DJ
Travel info (coming earlier? Carpooling?)
Plus-one (“Coming alone or with someone?”)
Directions and programme delivered directly

All on one page, stored digitally.

3. No transcription errors

Anyone who has ever typed reply cards into a spreadsheet knows: deciphering handwriting, interpreting ticks, reading allergy scrawls. With digital RSVP all answers land straight in a list, no transcription step.

4. Follow-ups are easier

Anyone who hasn’t replied is immediately visible in the system. A short reminder email or WhatsApp, done. With paper cards you need a separate tracker.

5. Less paper, less waste

Per invitation you save a reply card, an envelope, a stamp. At 80 guests that’s 80 fewer cards and 80 stamps (around €75 in postage alone). Also more sustainable.

How QR-code RSVP actually works

The flow is simple:

You create an online form with all the questions (often via the wedding-planner app or a service)
The form URL becomes a QR code
The QR code goes on the invitation, usually on an extra card or at the bottom
Guest scans with their phone, lands on the form
The answer is automatically added to your guest list

Some couples also include a text link, in case someone has no QR scanner to hand.

Things to keep in mind

Not every guest is digital

For great-aunt Brigitte at 84 a QR code probably won’t work. Three solutions:

Hybrid approach: older guests or those without a smartphone, still ring them
Involve a family member: a family member handles entry for non-digital guests
Backup phone number: put it on the invitation: “No QR code handy? Give us a ring at …”

Simple language

Don’t make the form too long. Eight to ten fields is enough. Faced with 25 questions people click away. Actually useful:

Name(s)
Yes / No / Maybe
Number of people
Meal preference
Allergies
Accommodation desired? Yes/No
Optional: song request
Optional: message to the couple

Set a clear deadline

“Please reply by 15 May 2026”, a concrete deadline pulls in far more answers than a vague “soon”. Plan 4 to 6 weeks before the wedding as the cutoff, so you have time for seating, catering confirmation and hotel block.

Send a confirmation

After submitting the form, the guest should get a short confirmation, by email or directly in the form. Everyone knows the answer arrived.

Design ideas for the QR code on the invitation

It doesn’t have to look like a subway ad:

Own RSVP card in the style of the invitation with the code in a subtle frame
QR code in the brand colour (instead of black)
Small icon in the centre, a heart, an initial, a couple icon
On the back of the invitation with a short line: “Please let us know by 15 May, scan the code or reply online at [URL].”

When digital RSVP isn’t worth it

For very small weddings (under 20 guests), the effort of a digital form is often greater than the benefit. A WhatsApp broadcast or personal calls are enough.

If your crowd is mostly older (your parents’ ballroom-dancing club, the seniors’ bridge club), stay classic. For everyone else, digital is faster, easier and greener.

What Marrily takes off your plate

In Marrily, RSVPs are tied directly to your guest list. You don’t have to build or configure anything: once you add a guest, you can send them an RSVP invitation, by email link or as a printable QR code.

Answers land automatically in the right guest profile: yes/no, plus-one, meal preference, allergies. Miri shows the dashboard live: “57 of 80 guests have replied, 12 still pending.” With one click you can send friendly reminders to non-responders.

And when you build the seating plan, allergies and meal preferences are visible right there. No more back-and-forth between three spreadsheets.
