For non-profits, your reputation for transparency and impact is what drives donations. If a donor or volunteer has a negative experience at an event, they can hurt your credibility on CharityNavigator or Google. Use 'Volunteer Voice' QR codes at every event.
If someone feels their time wasn't used well, you can reach out and thank them for their feedback immediately. This prevents negative public sentiment and turns a potential critic into a heard and valued partner in your mission.
