Said It Here

When is the right time to set your wedding RSVP deadline?

Setting an RSVP deadline too early backfires because guests' plans inevitably shift a long way out, resulting in inaccurate headcounts and constant changes. To get reliable numbers, RSVPs need to be collected as late as possible so you can avoid tracking down shifting commitments and dealing with outdated information.

What people tried

Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.

  1. 1
    Setting the RSVP deadline 4 to 6 weeks before the wedding
  2. 2
    Sending save-the-dates 6 to 12 months ahead for travel planning
  3. 3
    Building in a one-week buffer to chase down stragglers before vendor headcounts are due
  4. 4
    Sending save-the-dates and website information now but holding back the RSVP option until formal invitations are sent closer to the event

“Since inaccurate RSVPs are completely useless, there is a reason RSVPs are collected as late as you can possibly take them, even for international events.”source ↗

“Of course we would like to get a sense of numbers as early as possible, but we don’t want to set the deadline so early, that life will inevitably get in the way and guests will be changing their RSVPs well after the deadline.”source ↗
