Getting married means writing a lot of things you have never had to write before, and the RSVP trips up more couples than you might expect. It is a small piece of text, yet it has to do a lot of work: tell guests what they are being asked, gather the information you actually need, and set the tone for the day ahead. Word it clearly and warmly, and replies come back quickly and correctly. Word it vaguely, and you will spend weeks chasing people for answers to questions you never actually asked.

This guide covers what to include, how to phrase requests without sounding demanding, and how to handle the etiquette questions that catch most couples out: plus-ones, children, evening guests and late replies.

Why your RSVP wording matters

An RSVP only works if guests know exactly what they are confirming. Phrases like "kindly respond" or "regrets only" sound traditional, but they leave people guessing about deadlines, plus-ones and whether children are welcome. The result is a slow trickle of replies, a string of follow-up phone calls, and a final guest count you are never quite sure of until the week before the wedding.

The fix is not to write more, it is to write more specifically. A good RSVP tells guests three things: what they are being invited to, what you need from them, and by when.

What to include on your RSVP

Guest names, printed exactly as you want them to reply

On printed cards, pre-print the names of those invited on the reply line itself, rather than leaving a blank for guests to fill in. This removes any ambiguity about who has been invited and stops an extra name or two creeping onto the list. Online, the same principle applies: a form or message that already shows a guest's name and asks them to confirm is far less likely to cause confusion than a blank field.

Which parts of the day they are invited to

If you are running more than one event, perhaps a ceremony, a wedding breakfast and an evening reception, say so plainly. Guests should never have to guess from a save the date whether they are welcome at the meal or only the evening celebrations. This is one of the areas where a paper process tends to fall down, since every guest needs the right combination of events spelled out individually. It is also why so many couples now handle it through tools built for exactly this kind of multi-event tracking (see the Features page), so a guest invited to the ceremony and evening only ever sees those two options, never the full wedding breakfast.

Meal choices and dietary requirements

Ask for meal choice and any dietary needs in the same reply, rather than as a separate follow-up later. It saves you a second round of messages, and it means your caterer gets accurate numbers the first time.

A clear, kindly worded deadline

Give an actual date, and phrase it so it does not sound harsh: "Please reply by 14 February so we can confirm numbers with our caterer" reads far better than a bare cut-off date with no explanation.

Example RSVP wording you can use

Traditional printed card wording

M_______________________ kindly accepts / declines the invitation of [Couple's names] for Saturday, 12 June Number attending: ____ Meal choice: Chicken / Fish / Vegetarian Please reply by 1 May

A more relaxed version, for a less formal wedding, might simply read: "We would love you to join us! Please let us know if you can make it, and pop your meal choice on the card, by 1 May."

Wording for evening only guests

"We would love for you to join us for the evening celebrations from 7.30pm. Please let us know if you can make it by [date]."

Wording for an online RSVP

Online RSVPs can afford to be more conversational than a printed card, because there is a back and forth rather than a single reply slip. Instead of a rigid form, a message might read: "Hi Sarah, we are so pleased you can make it to the wedding! Could you let us know if you will be bringing anyone, and whether either of you has any dietary requirements?" That kind of natural exchange is exactly what a WhatsApp based RSVP allows for. You can try the demo to see how a real conversation flows, without a single form field in sight.

The etiquette questions couples ask most

Plus-ones. Word the restriction politely rather than leaving it ambiguous. "This invitation is for Jamie only" is clearer, and kinder in the long run, than an unaddressed envelope that leaves guests unsure whether to ask.

Children. State it plainly either way: "We love your little ones, but this evening is for adults only" or, if they are welcome, simply add a line for "Number of children attending".

Deadlines and chasing. It is entirely acceptable to send a gentle reminder to guests who have not replied by the deadline. A short, friendly nudge a few days beforehand, rather than silence followed by a terse phone call, keeps things civil on both sides. This is precisely how it works when reminders are handled automatically: a polite follow-up goes out to anyone who has not yet responded, so you are not the one doing the chasing between now and the big day. You can read more about how it works if you would like to see the process end to end.

Why more couples are putting their RSVP online

Printed cards look lovely on the mantelpiece, but they rely on a guest owning a stamp, finding a postbox, and replying before they forget. An online RSVP, whether through a form or a WhatsApp conversation, removes most of that friction and gives you a live, accurate count rather than a stack of cards to tally by hand. If you are weighing up whether it is worth it for your wedding size, the pricing page breaks down what is included at each guest count, so you can compare it fairly against the cost and time of printing, posting and chasing a few hundred cards yourself.

Get the wording right, then let the system do the rest

Good RSVP wording is really just good communication: say what you mean, ask for what you need, and make it easy for people to reply. Once the wording is right, the rest comes down to giving guests a simple way to respond, whether that is a stamped envelope or a message on their phone.
