What sponsors actually want to see in a post-event report
Sponsor renewals don't happen because the event was good. They happen because the sponsor can prove the event was good — to their boss, their marketing team, or their board. And they can't prove that with a PDF containing three photos and an estimated headcount.
If you want sponsors to come back next year, you need to give them data they can actually put in a business case. Here's what that looks like.
What sponsors actually want
After years of working with event organisers and their sponsor relationships, we've seen what gets renewals and what gets ghosted. Sponsors care about five things, roughly in this order.
Lead data. Who visited their booth. Contact details. Engagement level — did someone scan a badge and walk away, or did they sit down for a 15-minute conversation? The difference between "247 badge scans" and "247 leads, 38 qualified conversations, 12 meeting requests" is the difference between a number and a pipeline.
Visibility metrics. Where did their brand appear? On the schedule? In the event app? On floor plan signage? On the website? Sponsors pay for visibility. They want to know where they got it and how much of it they received relative to what was promised.
Attendance data. How many people were at the event overall? How many attended their sponsored session? What was the demographic breakdown? A sponsor targeting CTOs doesn't care about total headcount — they care about how many CTOs were in the room.
Engagement metrics. Booth traffic patterns, meeting bookings through the event app, session Q&A participation, post-session survey responses. These are the signals that tell a sponsor whether attendees were passively present or actively interested.
Comparison to investment. This is the one most organisers skip, and it's the one that matters most. If a sponsor paid $15,000, they want to know what that $15,000 bought them in concrete terms. Cost per lead. Cost per qualified conversation. Cost per brand impression. Without this, the sponsor has to build the business case themselves — and most won't bother.
What most organisers actually send
A PDF. Maybe a PowerPoint. It contains the total attendance number, a few photos of the sponsor's booth, a logo on a "thank you to our sponsors" slide, and a paragraph saying the event was a success.
This is not a report. This is a participation certificate.
The sponsor's marketing team looks at it, can't extract anything useful for their ROI analysis, and files it somewhere it'll never be opened again. When renewal time comes around, the conversation starts from zero because there's no data to build on.
What a useful sponsor report looks like
A report that gets renewals contains specifics. Not "great foot traffic at your booth" but "412 badge scans, 67 qualified leads captured, 23 meeting requests, average engagement time of 4.2 minutes."
It maps what was promised against what was delivered. The sponsorship package included logo placement on the schedule, a sponsored session, and a booth in the premium area. The report shows where the logo appeared (with screenshots or links), the session attendance and engagement metrics, and the booth traffic data.
It includes comparison to investment. "Your $12,000 Gold sponsorship generated 67 qualified leads at a cost per lead of $179, with 23 direct meeting bookings at a cost per meeting of $521." That's a number a marketing director can take to their CFO.
How ema makes this possible
You can't report on data you didn't capture. That's why sponsor reporting starts long before the post-event PDF — it starts with how you manage sponsors and exhibitors throughout the event.
ema's exhibitor and sponsor management tracks the full sponsor relationship: what was promised in the package, what's been delivered, and what data is being collected along the way. Lead capture at booths records who visited and how they engaged. Session attendance is tracked through QR check-in, giving you actual numbers rather than estimates.
Because the floor plan, schedule, sponsor profiles, and attendee data all live in the same system, the report can pull from all of them. You're not manually combining data from four different tools and hoping the numbers align.
The result is a post-event report that tells sponsors what they got, how it performed, and what it was worth. Not a PDF with photos. A business case for renewal.
The bottom line
Sponsor renewals are won or lost in the report. Organisers who send data-backed reports with real ROI metrics get sponsors back. Organisers who send a thank-you email and a headcount don't.
The data isn't hard to collect. It just needs to be collected in the first place, connected across your event systems, and presented in a format that helps sponsors justify the spend. That's the bar. Most events aren't clearing it.
