How to follow up leads after a trade show in 48 hours

Follow up every trade show or exhibition lead within 48 hours, and message your hot leads on the day you meet them. Sort leads into hot, warm and cold the same evening, send a short personal WhatsApp message that mentions what they asked about, then phone the hot ones the next working day. The plan starts on the stand, where you capture a WhatsApp number, a one-line note and consent to message.

Why event leads go cold

A visitor speaks to dozens of exhibitors in one day. Your team returns to a full inbox and a list of badge scans with no notes. The longer the gap before your first message, the less either side remembers about why the conversation mattered.

What the numbers do and do not show

You will see “80% of trade show leads are never followed up” credited to CEIR on many pages. We could not trace that figure to a primary source, so we do not rely on it.

Momencio, an event software vendor, says, citing its own 2026 report on US B2B events, that 40% of exhibitors wait three to five days to follow up, and that 80% of leads receive no follow-up at all. The page gives no sample size or method, so read those as one vendor’s figures.

The 2007 Lead Response Management study, run with Professor Oldroyd of MIT on InsideSales.com data, looked at three years of data from six companies: more than 15,000 leads from web forms and more than 100,000 call attempts. The odds of qualifying a lead fell 21-fold when the first call came after 30 minutes instead of 5.

That study measured phone calls to people who had just filled in a web form. It did not measure event leads. Take the direction from it (sooner is better) and leave the exact minutes. Our source-checked lead response time statistics cover what each study measured.

Before the show: what to capture, and consent

A badge scan gives you a name and an email address. A follow-up needs more. Capture five things for every conversation:

1. Name and role. Whether they decide, influence or research.
2. Company.
3. WhatsApp number in international format (starting +234, +44, +254 and so on).
4. What they asked about, in one line. “Wants weekly chilled deliveries from Lagos to Abuja from January, comparing two suppliers” is a lead. A bare scan is a name.
5. Consent to message them, and the channel they prefer.

Add a hot, warm or cold rating and the name of the person who had the conversation. A short phone form or a shared spreadsheet is enough.

Get consent on the stand

WhatsApp’s Business Messaging Policy says you may only contact people if they have given you their mobile phone number or username and you have received opt-in permission (checked on 2 October 2026). Meta’s opt-in guidance says the opt-in must make clear that the person is agreeing to receive messages over WhatsApp, and must name your business. In person or on paper counts.

A tick box does the job: “Yes, Delta Freight can message me on WhatsApp about my enquiry.”

The law applies as well. In the UK, the ICO’s guidance treats texts and direct messages as electronic mail, and marketing to individuals needs specific consent, with a narrow exception for existing customers. Other countries have their own rules, so check the law where you exhibit. This is general information, not legal advice.

Let the visitor message you first

Put a QR code on the stand that opens a WhatsApp chat with your business number. When the visitor sends the first message, you have their number and a written record.

If your team uses the WhatsApp Business Platform (the version behind most shared inboxes and CRMs), that message opens a 24-hour customer service window. Meta’s pricing documentation says non-template messages are free and can only be sent inside an open window (checked on 2 October 2026). After that you need an approved template. Our guide to the WhatsApp 24-hour rule explains the detail.

So get two or three follow-up templates approved before the show, and hold time in each rep’s diary for calls on the two days after.

The 48-hour timeline

Hour 0 is the moment the show closes on the day you met the lead. At a three-day exhibition, run the plan for each day’s leads.

Hours 0 to 6: sort hot, warm and cold

Do this the same evening, while the stand team still remembers faces.

• Hot: named a need and a date or budget, or asked for a price, a quote (quotation) or a meeting.
• Warm: has a real problem but no date, or is not the person who decides.
• Cold: took a brochure, entered the prize draw, or is a student, supplier or competitor.

Give every hot and warm lead one owner and one next step with a date. Merge duplicates.

If a hot lead messaged your WhatsApp number on the stand, reply tonight while the window is open.

Hours 6 to 24: the first message on WhatsApp

For many buyers in Lagos, Nairobi and Cairo, WhatsApp is where business conversations already happen. In the UK it varies by sector, so ask on the stand which channel they prefer.

Keep the first message under 60 words. Say who you are, mention what they asked about, and ask for one thing. Send it between 09:00 and 17:00 in their time zone.

These examples use a sample exhibitor, Delta Freight, with Amaka as the rep.

Hot lead

Hi Tolu, Amaka from Delta Freight here. We met at our stand today. You asked about weekly chilled deliveries from Lagos to Abuja starting in January. I have the route prices ready. Can I call you tomorrow at 10:00 or 14:30 to go through them?

Warm lead

Hi Sam, Amaka from Delta Freight. Thanks for stopping at our stand yesterday. You said Nile Motors will review its parts deliveries next quarter. Here is the one-page rate guide I promised. Which matters more to you at the moment: cost per trip or delivery time?

Cold lead

Hi, Amaka from Delta Freight. Thanks for visiting our stand at the show. I will not fill your inbox. If freight comes up at Kite Travel this year, reply here and I will answer you myself. Reply STOP and I will not message again.

If the 24-hour window has closed, or the lead never messaged you, send an approved template instead. Meta has charged for templates on a per-message basis since 1 July 2025, according to its pricing documentation, so save templates for leads worth the cost.

On the same day, email anyone who gave an email address but no WhatsApp consent. For more wording, see our WhatsApp sales scripts for every deal stage.

Hours 24 to 48: calls and booked meetings

Call every hot lead who has not replied, once in the morning and once in the afternoon. If nobody answers, send one line on WhatsApp: “Tried to call about the January deliveries. Is 16:00 today or 09:30 tomorrow better?”

Always offer two specific times, or a booking link.

Send warm leads the thing you promised (the price guide or the answer to their question), then ask one question that moves them closer to a date.

By hour 48, check four things:

1. Every lead has had one message.
2. Every hot lead has had a call attempt.
3. Booked meetings are in the calendar with an owner.
4. Each lead sits in the right stage of your pipeline. If your stages need work, start with our guide to sales pipeline stages for small teams.

Days 3 to 30: the slower follow-up

Many event leads are months away from a decision. A workable rhythm is day 3, day 7, day 14 and day 30. This is a starting point and not a research finding. Change the channel and the content each time.

End with a closing message on day 30 that says you will stop and that they can reply at any time. Move cold leads to an occasional update with a clear way to opt out. If anyone asks you to stop, stop that day. Our guide on how many follow-ups to send before giving up goes through the evidence.

What to measure afterwards

Hold a debrief within a week of the show. Bring six numbers:

• Leads captured, and how many had a note and consent.
• Share of leads contacted within 48 hours.
• Replies received.
• Meetings booked.
• Quotes or quotations sent.
• Deals won and their value at 30, 60 and 90 days.

Divide the full cost of the stand by the meetings booked. That figure helps you decide whether to exhibit again.

Frequently asked questions

How quickly should I follow up after a trade show?

Within 48 hours for every lead, and on the same day for hot leads. Start the clock when the show closes on the day you met them, not when the whole event ends.

How many times should I follow up before giving up?

We have not found a reliable study for event leads. A sensible plan is five or six contacts over 30 days across WhatsApp, phone and email, ending with a polite closing message.

What if prospects don’t respond to my first follow-up?

Change the channel before you change the message. If WhatsApp was first, phone the hot leads and email the warm ones. On the second attempt, send something useful and ask for one small thing.

How do you qualify exhibition leads?

Qualify on the stand with three questions: what they need, when they need it, and who decides. A named need with a date or budget is hot. A real problem with no date is warm. Everyone else is cold.

Can the follow-up be automated?

Parts of it can. Automate the thank-you message, the reminder to the lead owner and the template messages on day 3 and day 7. Keep the first message to a hot lead and every phone call personal, because they depend on what was said at the stand.
