How to follow up exhibition leads within 48 hours (the maths of decay)

Every exhibition ends the same way. The stand is packed down, the team gets on a train, and a list of names sits in a portal or a spreadsheet waiting for someone to have a free afternoon. The list itself does not decay. What decays is the visitor's memory of the conversation, and with it the reason they gave you their details.

Why the first two days carry most of the outcome

A widely cited study of lead response times, published in Harvard Business Review in 2011 by James Oldroyd and colleagues, found that firms which contacted an enquiry within an hour were far more likely to qualify it than firms that waited even a few hours. The same pattern has been observed repeatedly in sales research since: the value of a contact attempt is highest while the conversation is still the visitor's most recent memory of your category.

At a trade show you are competing with a coach journey home, forty other stands, and a full inbox. The rep who writes on Tuesday is not describing a conversation any more, they are describing a badge.

The maths on your own stand

Take a realistic three-day show: 120 badge scans, of which perhaps 35 were genuine conversations about a live problem. Suppose a same-week follow-up converts 1 in 6 of those 35, and a two-week follow-up converts 1 in 20. That is roughly six opportunities against fewer than two, from precisely the same stand, the same spend and the same people.

Do the sum with your own numbers instead of mine, because yours are the ones that will persuade a manager. Multiply expected conversations by a conservative close rate, then multiply by average deal value. The difference between the fast and slow column is what response time is worth to you. If a single extra deal is bigger than the cost of the capture tool, the argument ends there.

The arithmetic also exposes the real constraint. Thirty-five personal messages is perhaps three hours of work, not three weeks. The obstacle is almost never capacity. It is that the information needed to write a personal message was never captured at the stand.

A 48-hour sequence a stand team can actually run

1. The evening of the conversation. Add one line to each lead: what they asked, what you promised, and whether they said you could contact them. This is the step everything else depends on, and it takes seconds while the visitor is still walking away.
2. Within 24 hours. A short personal note referencing the conversation, one relevant piece of proof, and one clear next step. Confirm or suggest a time to talk rather than asking whether they would like some information.
3. Within 48 hours. A second touch on the channel they used at the show — a connection request if they asked for one, a phone call if they gave a direct line, otherwise a reply in the same thread rather than a fresh email.
4. Day five. Something useful that is not a chase: a short note answering the question they actually asked, or an introduction to the right person on your side.
5. Day ten. A clean close-the-loop message. Either they want a conversation now or they do not, and both answers are useful. Mark the lead accordingly so the next show does not inherit an ambiguous list.

What belongs in the first message

Four elements, roughly ninety words. Their name and company as it appeared on the badge, so they can tell it is not a mail merge. The specific thing you discussed. One relevant proof point, ideally from a similar company or sector. And a concrete ask with two options for a time.

What should not be in it: a brochure attached to a generic greeting, three paragraphs about your company history, or a request to "book a demo" with no acknowledgment that you have already met.

Where teams go wrong

• Waiting for the organiser's export. Some lead retrieval portals release data days after the show, and some only during the event. If your follow-up clock starts when the spreadsheet arrives, you have already spent your best window.
• One mail merge for everyone. A mail merge is better than silence, but it wastes the one advantage you have over every competitor who also scanned the badge: you were there.
• No owner per lead. "The team will follow up" means nobody will. Each lead needs a name attached before the stand is packed down.
• No consent note. Knowing who said yes to contact changes how you can write to them, and it is much easier to record at the stand than to reconstruct later.

Make it a system, not a scramble

The teams that follow up reliably are not more disciplined than everyone else. They capture the note at the point of conversation, assign an owner, and set a date that appears in someone's list on Monday morning. In StandProof that is a follow-up date on each lead and a filtered view of what is due, plus a clean CSV if your team works in a spreadsheet.

Whatever tool you use, test it against one question: on the Monday after the show, can a rep who was not on the stand read a lead record and write a personal message from it in under a minute? If the answer is no, the decay has already started. You can see how the capture and follow-up flow works on the pricing page, or read how it compares with an organiser lead retrieval package.
