Subject line: Thank you. Can we improve?
Thank you so much for your help in making our recent conference a success. We’d like to express our sincere gratitude for your fine cooperation with our administration office: you checked in, you stayed on time, and you gave a wonderful talk.
We would really appreciate it if you could help us do better. Tell us, do you see any place where we in the administration office could improve?
Please be open and frank, otherwise we won’t improve.
