When to send it
Collect feedback twice from the same survey: once in the room and once the next day. Put the QR code on the closing slide and on printed cards at the exits, and mention it from the stage before the final session wraps up. Then email the link the next morning to everyone who registered, for those who left early or forgot. The survey takes one response per phone by default, so the same phone can't answer twice.
Why these questions
Overall satisfaction comes first, followed by a grid that rates six parts of the event: talks, speakers or hosts, venue, food and drinks, chances to meet people, and organisation and timing. Events have many moving parts, and the overall number rarely tells you which one to fix. The grid does. Delete any row that doesn't apply, such as food at an evening talk.
Two open questions follow: the highlight, and what to change next time. Highlights tell you what to keep and which speakers to invite back. The change question is where you'll hear about queues, sound problems and sessions that overran.
The last page asks whether they'd come to your next event. Anyone who answers "probably not" is asked what would change their mind. Read those answers carefully: a handful of them can explain more than every score on the grid.
The coupon
A unique 20% code off the next event ticket thanks attendees for their time and gives them a reason to book early. Unique codes matter for events because ticket discounts travel fast through community groups and social posts. Every attendee who completes the survey gets one, however they scored the event.
What to do with the answers
Within a week, send attendees a short "what we heard" note with two or three changes you'll make. It shows people their feedback mattered and is a natural moment to announce the next date. Keep the grid scores for each event in one place so you can see whether a new venue or format actually helped.
If you want to quote highlights in your marketing, ask the person first. For online sessions, use the webinar feedback template; for smaller regular gatherings, the community meetup template; and for hands-on training days, workshop feedback.
