Follow up within 24 hours for your hottest leads and within two business days for everyone else. Grade every lead at the booth, then run a 10-day cadence: a personal email on day one, a call on day two or three, a useful resource around day five, and a final check-in by day ten.
I've helped companies exhibit since 2006, and I've worked with hundreds of them. This is the plan I recommend for the two weeks after a show. Adjust the days to fit your sales cycle, but keep the order.
Why speed matters
Speed matters because the booth conversation fades fast. By the end of a show, a visitor has talked with a lot of exhibitors, and the details of what they asked you for start to blur. A personal note that arrives while the conversation is still fresh reminds them who you are and what you promised. Wait too long and your email looks like every other one in their inbox, and a competitor may have already called. That's why I move fast on booth leads.
Michael's Tip
Block time on your calendar for the day after the show before you leave for it. Your first emails to A leads should go out within 24 hours, and that's hard to do if your first day back is already full. Have each person who met an A lead send that email themselves.
Before the show ends: grade every lead at the booth
Follow-up starts at the booth. Grade every lead as you capture it:
- A: real need, a say in buying and timing in the next quarter
- B: real interest, but later timing
- C: information only
In the notes, write what they asked for, the next step you promised and who owns it. These are the same grades I use in my booth staff huddle script.
Lead retrieval works differently at every show. IDDBA lists SWAP by Maritz and SWAP REACH by Maritz as its options (IDDBA). At CES, your company's Registration Coordinator orders lead retrieval through the Exhibitor Dashboard (CES). Whatever your show uses, export a sample lead file before the doors open so you know the data will come out the way you need it.
Michael's Tip
The note field I'd make everyone fill in is the next step you promised. If a visitor says "send me pricing" and nobody writes it down, nobody sends it. One line is enough for whoever follows up.
The 10-day cadence
This is my recommended plan, counted in business days after the show closes.
Keep subject lines short and specific. A few examples:
- "Following up on our talk about [topic] at [show]"
- "The [resource] I promised at [show]"
- "Next step on [topic]?"
Michael's Tip
I'd stop after the day-10 check-in if there's no reply and move the lead to a slower nurture track. Only add them to marketing email if they've said yes to it. Keep the notes, because a lead who goes quiet for two weeks may still buy later.
Who owns each lead
Decide ownership before the show, not after. The person who met the visitor sends the first email, since that's the name and face they remember. If a lead belongs to a territory or account owner, the booth staffer still sends the first note and copies the owner. Sales leadership checks progress on day 3 and again on day 10, so nothing sits.
Where AI lead capture helps in 2026-2027, and where it doesn't
Lead apps are changing quickly. At OTC 2026, the show's exclusive lead retrieval vendor, Spargo, offered "SMART CAPTURE! Mobile AI," which it says "researches leads as you scan them" and returns a company overview and a lead score within seconds. Its standard CAPTURE! app lets staff scan badges, add notes, qualify prospects and export leads, with CRM integration (OTC 2026 lead retrieval flyer, PDF). That's one vendor describing its own product, and I'm not making claims about its accuracy.
A company overview saves your sales team research time. A score is a starting point. Check both against what the visitor actually said, which is in your staffer's notes. If your app records audio, check the consent rules where you're exhibiting with your legal team before you turn that on.
Michael's Tip
Treat an AI lead score as a first sort, not a verdict. Before you call, read your staffer's notes and compare the score with what the visitor actually said. When the two disagree, go with the notes.
Email rules for trade show leads
A badge scan isn't a newsletter sign-up. The FTC's CAN-SPAM guide says the law covers all commercial email and "makes no exception for business-to-business email." Commercial messages need a valid physical postal address and a clear way to opt out, and you have to honor opt-outs within 10 business days. Each violating email can cost up to $53,088 (FTC).
Google's sender guidelines tell senders not to buy email addresses or email people who didn't sign up. Senders of more than 5,000 messages a day to Gmail accounts must support one-click unsubscribe for marketing messages and keep spam rates below 0.3% (Google).
So send personal, one-to-one follow-up to the people you met, and ask before you add anyone to a marketing list. This isn't legal advice. Check with your own legal team on how the rules apply to you.
Measure what happened
At day 10, and again at 30, 60 and 90 days, count replies, meetings booked and opportunities by lead grade. Joe Federbush, president of EVOLIO Marketing, said in The Exhibitor Advocate's May 2026 release that exhibitors "are increasingly evaluating cost-per-qualified lead and pipeline contribution" (The Exhibitor Advocate). Leads are one of the 3 things to measure at trade shows, and I've also written about how executives should measure trade show results. There's more in the Measurement and Lead Follow-Up sections.
If you exhibited at IAAPA Expo in Orlando or RSNA in Chicago in late 2026, this cadence fits the weeks after those shows. More dates are on our show guides page, and you can find more trade shows there too. For pre-show invites, see my pre-show email templates and the marketing section, and skim the 25 most common trade show mistakes.
Trade show lead follow-up FAQs
How soon should you follow up after a trade show?
Within 24 hours for your hottest leads and within two business days for the rest. The sooner you reach out, the more likely they are to remember your conversation and what you promised.
How many times should I follow up with a trade show lead?
I plan four or five touches over 10 business days, mixing email and phone, then move people who haven't replied into a slower nurture track.
Should I call or email trade show leads first?
Email first, from the person they met, the same or next day, then call within two or three days. A quick personal email gives the call context.
How do I prioritize trade show leads?
Grade them at the booth: A for real need and near-term timing, B for interest with later timing, C for information only. Call A leads first.
Can I add trade show leads to my email newsletter?
Be careful. CAN-SPAM applies to business email, and Google tells senders not to email people who didn't sign up. Ask for permission before adding leads to marketing lists.
How can AI help with trade show lead follow-up?
Some official lead retrieval apps now research each lead as you scan, giving a company overview and a lead score. Use those as a starting point, and check them against your notes.
What should a trade show follow-up email say?
Mention where you met and what you talked about, deliver what you promised, and suggest one clear next step with a date. Keep it short and personal.
Want a second pair of eyes on your follow-up plan?
Just back from a show with a stack of leads? Tell me how you're following up, and I'll tell you what I'd change.
