Post-event survey: what to ask after a conference or webinar
A post-event survey has a very short attention window: the person is already back in their routine, and the longer the gap between the event and sending it, the lower the response rate. This survey's design depends more on timing and length than on the content itself.
When to send it
Within 24 hours of the event is the window that best balances fresh memory with willingness to respond. Past 48-72 hours, the response rate drops noticeably because the experience isn't top of mind anymore and competes with the rest of the inbox.
The essential questions
- "How satisfied are you with the event overall?" — CSAT, 5-point scale.
- "How likely are you to recommend this event to a colleague?" — event NPS.
- "What was the most valuable thing you took away?" — open text, optional.
- "What would you improve for the next edition?" — open text, optional.
Event-type-specific questions
For a conference with multiple talks, adding "Which session was your favorite?" (single choice, with talks as options) gives specific, actionable input for the next edition. For a webinar, "Was the content at the level you expected?" (Too basic / Just right / Too advanced) helps calibrate future audiences.
Using the survey to qualify leads
If the event has a sales angle (a trade show, a product webinar), adding one or two qualifying questions at the end — company size, interest in a demo, rough budget — turns the survey into a source of qualified leads, with no separate form needed. In SurvIQ, mapping the contact questions (name, email, company) to lead fields turns every completed response into a tracked contact automatically.
How to distribute it
A QR code on the event's closing screen (for anyone completing check-out) combined with an email to the registered list within 24 hours covers both people still on-site and those who left before closing.
Keep it short
Five to seven questions is a reasonable ceiling for a post-event survey — the person already invested time attending, and a long survey afterward feels like asking for more than is fair. If there are sales-qualifying questions, they go at the end, after the satisfaction questions, never before.
