Set your RSVP deadline for 3 to 4 weeks before the wedding, state plus-one rules directly on each invitation, and chase missing replies with a friendly personal message about a week after the deadline. Those three habits prevent almost every guest-count headache, so let us look at how to handle each one gracefully.
Your caterer, venue, and stationer all need a final headcount, and they usually want it 2 to 3 weeks before the day. Work backward from the earliest of those dates and give yourself a buffer.
An online RSVP makes this far easier than paper cards. Guests reply in seconds from their phones, and you see the running total update instantly instead of decoding handwriting weeks later.
The kindest approach is also the clearest one: decide who gets a plus-one before you address a single envelope, then make it unmistakable on the invitation. Etiquette generally says to offer a plus-one to:
Address the envelope and RSVP to the specific people invited. "Jordan Lee and Guest" signals an open plus-one, while listing only "Jordan Lee" signals a single seat. If a guest asks to bring someone you did not include, it is perfectly acceptable to reply warmly that you are keeping the celebration small and cannot extend extra invitations. Say it once, apply it to everyone, and you stay fair.
Some guests will forget. That is normal, and it is not rude to follow up. Wait until a few days after your deadline, then reach out personally rather than sending a guilt-tripping group blast.
Keep the tone light. Most non-responders are simply busy, not snubbing you, and a quick nudge usually clears the whole list.
Collecting replies, meal choices, and song requests in one place saves hours of spreadsheet work. A free wedding website from MyKnotBook gives you online RSVPs, seating and table planning, and no-app guest photo and video uploads, with an optional one-time EUR 159 Premium and no subscription. Your headcount, dietary notes, and plus-one details stay in a single dashboard that updates the moment a guest responds.
RSVP comes from the French "repondez s'il vous plait," meaning "please reply." It is a request for every invited guest to confirm whether they will attend, ideally by the date printed on the card.
No. Plus-ones are a courtesy, not an obligation. As long as you apply the same rule to everyone and invite established couples together, limiting extra guests to manage budget or space is completely acceptable.
Follow up once by text or phone after your deadline. If you still hear nothing before the caterer's cutoff, count them as a no, and let them know there may not be a seat if they turn up unannounced.
