The show ends.
The opportunity
continues.

Start with the timing you agreed with each visitor. Send promised materials and time-sensitive answers promptly, and let the person know if you need longer. Review the remaining leads soon after the show while the conversations are fresh, assign owners, and set realistic follow-up dates. A relevant message that keeps a promise matters more than sending every contact the same email at once.

Remind the person where you met and mention the need or question they shared. Deliver what you promised, or say when it will arrive. Suggest one clear next step that fits the conversation. If no next step was agreed, ask a brief, courteous question about whether further information would be useful. Keep it short and avoid claiming an interest they did not express.

Bring the team together while the details are fresh. Compare the goals with the evidence you have, then discuss what helped, what got in the way, and what visitors repeatedly asked. Separate observations from assumptions. Finish with a short list of changes, an owner and date for each, and any missing results you will review later.

Use the person's stated timing and preferences to guide the cadence. Each message should have a useful reason to exist. After unanswered attempts, send a courteous closing note and pause rather than continuing indefinitely. If the person asks you to stop, stop and update the record. For a later project, agree on a future check-in when possible.

Compare results with the goals you set before the show. Track qualified leads, booked meetings, completed next steps, and later opportunities or revenue where you can connect them to the event. Compare those results with the full cost and record useful customer learning too. Set review dates that fit your sales cycle; early lead counts alone cannot tell you the final return.
