Post-event survey

Definition

A post-event survey is the questionnaire sent to attendees after the event to measure satisfaction, identify weak points and gather suggestions for future editions. It is the primary source of structured feedback to improve the next event.

Details and formula

Anatomy of an effective survey (max 8 questions, 3-minute completion):

1. NPS (Net Promoter Score): "From 0 to 10, would you recommend this event to a colleague?"

2. Closed quality questions: content, organization, venue, catering, networking (1–5 scale)

3. Favorite session (multiple choice from agenda)

4. Least useful session (multiple choice, important to improve next event)

5. Open question on "what to improve" (the richest insight source)

6. Interest in next events (for marketing pipeline)

7. Permission for sales contact (for lead qualification)

Context and typical ranges

Best practices to maximize response rate:

• Timing: send within 24h post-event (while memory is fresh). After 72h response rate drops 40%.
• Length: max 8 questions, 3 minutes stated. 20-question surveys see 5% completion.
• Mobile-first: 60% of surveys opened from smartphone, 1–5 scale with tap (no small sliders)
• Stated incentive: "in exchange for your opinion, we send you the full recording + slides" → +25% completion
• Personalization: pre-filled with name, recognize you attended specific sessions

B2B event benchmark: 25–40% completion rate. Below 20% there's a survey UX/timing problem.
