Frequently asked questions
How far in advance should the RSVP deadline be?
For weddings, most planners recommend 3–4 weeks before the event (giving you time to chase late responders and confirm numbers). Caterers typically need final numbers 10–21 days out.
When should I send invitations?
Wedding invitations should go out 6–8 weeks before the RSVP deadline. For destination weddings or holiday dates, 3–4 months ahead is better. Save-the-dates should go out 6–12 months in advance.
What if guests don't RSVP on time?
Build a 7-day chase window between your RSVP deadline and your caterer's cutoff. Send a reminder text or call non-responders. For meal choice weddings, assume the cheapest option for anyone who hasn't replied.

Why the RSVP deadline matters
Caterers, venues, and table planners all need confirmed numbers before a fixed deadline. Setting your RSVP date too late leaves no time to chase stragglers; too early and some guests haven't checked their calendars yet. 3–4 weeks before the caterer cutoff is the sweet spot.
Handling late RSVPs
Assume 10–20% of guests will miss the deadline. Send a reminder text or WhatsApp message 3 days before the cutoff — a friendly nudge dramatically improves response rates without feeling pushy.
