Signing up to a guest list costs a guest nothing. That is precisely why ignoring it costs them nothing either. Twenty to forty percent no-shows is normal on free lists — not carelessness on your guests' part, but the price of the low barrier that makes the list valuable in the first place.
Measure first, act second
Most venues estimate their rate and are wrong. The number you want is simple: check-ins ÷ sign-ups, across several events. Which is exactly why you need check-in data rather than just a list — see why a spreadsheet cannot give you that.
It gets interesting when you break the rate down: by promoter, by weekday, by how far ahead someone signed up. People who sign up three weeks out show up less often than people who sign up the day before. That alone changes when you release links.
What actually helps
- A small commitment. A confirming tap on the day, a token amount, named entries instead of "+3". Anything that makes the guest act once lifts the rate noticeably.
- Timing over volume. One reminder on the day works. Three across the week work worse than one, because they read as noise.
- A waitlist. It does two things: it backfills cancellations automatically, and it signals to the person holding a spot that the spot has value.
- Overbooking with your own number. If your rate sits reliably at 30%, you can price that in. Overbooking against a guessed rate produces exactly the argument at the door you were trying to avoid.
What does not help
More reminders. From the second message on, open rates fall faster than attendance rises — and you train your guests to ignore you.
Nor does penalising no-shows you never warned anyone about. Someone who does not make the list next time and cannot tell why simply stops coming.
EventSync derives the rate per event, promoter and guest straight from check-ins — you do not have to count anything to plan with your own number instead of a rule of thumb.
