How to RSVP on a Wedding Website: A Guest's Guide

Open the link the couple sent you, find the page called RSVP or Reply, and type your name exactly as it appears on your invitation. The site will show you your entry, ask whether you are coming, and in most cases ask about meals. It takes about two minutes, and you can usually change your answer later.

The rest of this page is for when that does not go smoothly, which is more often than you would think.

What is this link they have sent me?

It is the couple's wedding website. It has replaced the reply card that used to come with a paper invitation, and it usually holds the schedule, the venue address, travel and accommodation notes, a dress code, and the RSVP form.

You do not need an account. You do not need to download anything. If a site asks you to create a login just to reply, check you have followed the right link, because that is unusual.

Some couples send the same link three or four times over several months. That is deliberate. The page updates as details firm up, so the version you open in March may say more than the one you opened in January.

Why can't I find my name on the RSVP form?

This is the single most common problem, and it is almost never that you have been uninvited.

Work through these in order:

1. Search your surname on its own. Most forms match partial text. Typing three or four letters of your surname will find you faster than typing your full name and hitting one wrong character.
2. Use the name on the invitation, not the name you go by. If the envelope said Katherine and everyone calls you Kate, the guest list says Katherine. Married and maiden names catch people the same way.
3. Try your partner's name instead. Households are often stored as one entry under whoever the couple listed first. Searching for them will bring up both of you.
4. Check for a trailing space. Copying a name out of a message often carries an invisible space with it, and some forms treat that as a different name.

If none of that works, message the couple. They can see the list you cannot, and adding a missing guest takes them a few seconds. Do not fill in someone else's entry to get around it, because that overwrites their reply.

How do I RSVP for my whole household?

Usually you reply once, for everyone. When you find your entry, the other people in your household should appear alongside it, and you answer for each of them in turn.

If your children are not shown, they were not invited. This is worth saying plainly, because it is the awkward discovery a lot of guests make at this exact moment. It is a decision the couple made about numbers, not about your family. Ask them directly rather than adding names to the form.

If someone in your household is coming and someone is not, answer them separately. That is what the per-person options are for, and it is far more useful to the couple than a single yes with a note attached.

What if I don't know about my plus-one yet?

Accept for yourself and decline the plus-one, then message the couple to say you may know more by a certain date.

Do not hold your whole response back waiting to find out. An unanswered invitation looks identical to a guest who is ignoring it, and the couple will chase you. A reply with a caveat is much easier for them to work with than silence.

Whether you get a plus-one at all is the couple's decision, and it is set on their side before the form reaches you. If the option is not there, it was not offered.

Can I change my answer after I have submitted it?

Usually yes. Open the same link again, find your name, and update it. Wedding websites generally let guests edit their reply right up until the deadline the couple set, and the form then closes on its own.

After the deadline, message the couple directly rather than looking for a way to submit late. By that point they may already have given the venue a number, and a change that arrives through the form may not be seen. A message gets a human's attention.

Why are they asking about meals and allergies?

Because the caterer needs the count broken down by choice, not just a total, and someone has to assemble that list.

Be precise about which of your requirements is medical and which is preference. A kitchen treats a nut allergy and a dislike of nuts very differently, and writing "no nuts" for both gives them no way to tell. If it is an allergy, say allergy.

If you are answering for someone else in your household, ask them rather than guessing. Meal choices are the field most often changed after submission, and each change is a message the couple has to relay.

What if there is no website, just a phone number?

Reply the way they contacted you. If the invitation came by text, text back. If it came on paper with a phone number, call or message that number.

Say your name, say who you are replying for, and say yes or no clearly. "We would love to come, both of us" is a complete reply. "Sounds lovely!" is not one, and it will leave you on the chasing list.

The deadline has passed. What do I do?

Message the couple now, today, and apologise briefly without a long explanation.

Late replies are genuinely difficult at this stage because the numbers have usually moved on to the venue and the caterer, and a change can cost the couple money rather than just time. Being quick about it matters more than being sorry about it. If you cannot come, say so immediately, because that is the version of this news they can actually use.

If you are the one building the website your guests will use this on, the wedding RSVP tool lets you collect meal choices and household replies through your own custom questions, so none of the above lands in your messages.

A note on privacy

The form will ask for things the couple needs: your name, sometimes your address for a physical invitation, sometimes a phone number for day-of updates. It should not ask for payment details, a password, or anything about your finances. If it does, stop and contact the couple through a channel you already trust.
