The Complete Wedding RSVP Guide

Wedding RSVPs seem simple — ask people if they're coming, collect the answers. In practice, it's one of the most stressful parts of wedding planning. Guests reply late, forget to include dietary information, bring uninvited plus-ones, or simply don't respond at all. This guide covers everything you need to manage RSVPs efficiently.

When to send wedding invitations and RSVP deadlines

Communication	When to Send	Purpose
Save the date	12–18 months before (for summer/peak dates)	Reserve the date in guests' diaries
Save the date (off-peak)	6–12 months before	Reserve the date; less urgent
Formal invitations	6–8 weeks before (UK) / 8–12 weeks (destination)	Official invite with venue, time, dress code
RSVP deadline	3–4 weeks before the wedding	Gives time to chase, confirm numbers with caterer
Final numbers to caterer	2–3 weeks before	Most caterers require a final headcount

Tip: Set your RSVP deadline one week earlier than you actually need the numbers. This gives you a buffer to chase non-responders without the stress of a hard deadline looming.

What information to collect with each RSVP

Don't make guests answer multiple forms. Collect everything at once:

Attendance — Will they attend the ceremony, reception, or both?
Plus-one— If you've given guests a plus-one, collect the guest's full name (you'll need this for the seating chart and place cards)
Meal choice— If you're offering a choice of main courses at the wedding breakfast
Dietary requirements — Vegetarian, vegan, gluten free, allergies, or other restrictions; important for the caterer
Children — If children are invited, their names and ages for catering and seating
Song request — Optional, but guests enjoy it and it helps your DJ/band

Paper RSVP cards vs digital RSVPs

Most couples now use a mix or go fully digital. Here's how they compare:

	Paper RSVP Cards	Digital / Online RSVPs
Cost	£50–£200 for printing + postage	Free to low cost
Tracking	Manual — transcribe each response	Automatic — responses collected in one place
Ease for guests	No internet required; familiar	Faster; no stamp, no envelope
Guest demographics	Better for older guests who prefer paper	Works well for most guests under 70
Data quality	Legibility issues; incomplete responses common	Fields are required; no illegible handwriting
Response rates	Often lower — guests lose the card	Higher when you can send direct links

Many couples use a hybrid approach: QR code RSVP on paper invitation cards, directing guests to an online form. This works well for mixed guest demographics.

How to write wedding RSVP wording

Keep it simple. Your RSVP should tell guests exactly what to do and by when. A few examples:

Formal:
“Kindly respond by [date]. Please indicate your attendance, meal preference, and any dietary requirements.”

Informal:
“Let us know if you can make it by [date] — just scan the QR code or visit [link]. We'll need your meal choice and any dietary needs too.”

Digital-first:
“RSVP online by [date] at [link] or scan the code below. Takes less than a minute.”

What to do when guests don't reply

You will have non-responders. It's not rudeness — people are busy and forget. A chasing process helps:

One week after RSVP deadline— Send a brief, friendly reminder to everyone who hasn't responded. Keep it light: “We just want to make sure you got the invite — hope you can make it!”
Two weeks after deadline — Contact remaining non-responders directly (WhatsApp or phone call). At this point you need an answer.
Treat no response as a “no”— If you genuinely cannot get hold of someone by one week before your final caterer deadline, assume they're not coming. It's easier to add a last-minute “yes” than to deal with a caterer overage.

Digital RSVP advantage: ForeverAftersends individual RSVP cards by email directly to each guest. Each card has a unique link — so you can see exactly who has and hasn't responded, and resend to non-responders with one click.

Managing the RSVP data

Once responses come in, you need to track:

Confirmed attendees (total headcount, ceremony vs. reception)
Declined guests
Dietary requirements by guest name (share with caterer)
Meal choices (for the seating plan and caterer brief)
Plus-one names (for place cards)
Children attending (ages, for caterer and potentially seating)

Keeping this in a single place — rather than across emails, WhatsApp messages, and paper cards — prevents errors. ForeverAfter's guest management captures all of this automatically as guests respond to their digital RSVP cards.

Frequently asked questions

When should I send wedding invitations?

Send formal wedding invitations 6–8 weeks before the wedding for UK guests, or 10–12 weeks for destination or overseas weddings. Save the dates should go out 6–18 months ahead depending on how far guests need to travel and whether the date is in peak wedding season.

What should my RSVP deadline be?

Set your RSVP deadline 3–4 weeks before your wedding. Most caterers require final numbers 2–3 weeks in advance — so a 3–4 week deadline gives you time to chase non-responders before you need to submit numbers.

What do I do if more people RSVP yes than expected?

Contact your venue and caterer immediately — most can accommodate small increases (5–10 extra guests) with reasonable notice. If capacity is the issue, you'll need to have a difficult conversation with late responders about whether you can accommodate them.

Should I use paper or digital RSVPs?

Digital RSVPs are faster, cheaper, and easier to track. Paper RSVP cards work better for older guests or very formal weddings. Many couples use a QR code on paper invitations to bridge the gap — guests can use the QR code or you can add a paper alternative.
