Why a third of your registrations do not turn up — and what fixes it

The number is worse than you think

Free corporate and customer events routinely see thirty to fifty per cent of registrants not attend. Paid events do far better, which tells you the mechanism: registration without commitment is an intention, not a decision.

Plan against attendance, not registrations, and be explicit about the conversion rate you are assuming.

Reconfirm, close to the date

A short reconfirmation sequence in the final ten days — with a genuine reason to reply rather than a reminder — recovers a meaningful share. Asking people to actively confirm, rather than telling them the event is coming, is what changes the number.

Make the logistics obvious

A surprising proportion of no-shows are people who could not work out where to go, whether parking existed, what time they would be finished, or whether lunch was included. Joining instructions that answer those questions plainly reduce drop-off.

Give them something that only exists in the room

A session that will not be recorded, a peer conversation, a meeting with someone senior, an early look. The reason to attend has to be stronger on the Monday morning than it was at the moment of registration.

Overbook deliberately, not accidentally

If your model says 60 per cent attendance, register to 160 per cent of capacity with a managed waitlist, and hold catering guarantees against the attendance forecast rather than the registration count. Do it as a decision with numbers, not as a hope.
