Engaging event attendees — before, during and after the event

She sent the invitation three weeks in advance. Then nothing — until the day of the event. Of the 120 registered attendees, 84 showed up. Thirty-six no-shows, each with their own reason.

"I hadn't built a relationship," she says. "They'd registered. After that, I went silent."

Phase 1: Before the event

The period between registration and the event is the most undervalued phase. Attendees who register two weeks before an event and then hear nothing lose their motivation. Those who drop out on the day itself rarely do so for practical reasons — but out of a lack of mental engagement.

What works: three to four weeks before the event, send a brief question that prompts attendees to think about the theme. "What is the question you want answered?" or "What problem do you want to bring to the day?" This is not a survey — it is activation.

Introduce attendees to one another. A short "who's coming?" featuring five to eight attendee profiles raises anticipation and increases willingness to network.

Communicate the programme — but not everything. A little suspense works. Share the broad outline but save the details for the day itself.

Phase 2: During the event

An attendee who walks in without direction is already lost. The first ten minutes set the tone for the entire day.

What works: an active welcome in which attendees immediately do something — answer a question, find a person matching a description, start a first conversation. Walking in passively and sitting down is the worst possible start.

Interaction should have a low threshold. Voting via mobile phone, writing down a question and handing it in, discussing a proposition with a neighbour — these are formats in which even attendees who would not naturally raise their hand can participate.

Visible results. If attendees submit questions, actually address those questions — not only the easy ones. If there is a vote, show the outcome and do something with it.

Space for unexpected conversations. Not every moment needs to be programmed. Attendees appreciate the room to have spontaneous conversations that the programme never anticipated.

Phase 3: After the event

More than 80% of organisers send a thank-you email after an event. Fewer than 30% send something substantive — a summary, a resource, a follow-up question — in the two weeks that follow.

That is a missed opportunity. The two weeks after an event are the window in which insights are either translated into behaviour or forgotten. A good follow-up demonstrably increases the likelihood of behavioural change.

What works: a concrete action prompt ("What single change will you make next week based on today?"), a summary of the best insights, and one next step — not ten.

Celebrate the keeping of commitments. If attendees said they would do something, ask them about it. Not as a check-up, but as genuine interest. This strengthens the relationship and the effectiveness of the event alike.

The no-show problem

No-show rates at free events average 30–40%. At paid events, they are 5–10%. The difference is commitment.

Reduce no-shows by: asking for a small confirmation investment (answering a brief question upon registration), sending a reminder email two days before the event, and providing a direct confirmation of value — not "don't forget the event is on" but "here is why tomorrow is worth your time."

The lesson

The event manager from the opening now sends a small weekly update during the three weeks before her events. "Nothing long — three sentences. A glimpse of what's coming, a question, an introduction to a speaker." Her no-show rate has fallen from 30% to 12%.

"I didn't just expect them to turn up. I invited them and then brought them along with me. That's the difference."
