Donor Surveys: What to Ask and What to Do With the Answers

A donor survey tells you why people give and what keeps them. What to ask, how to keep it short, how to boost responses, and how to actually act on the answers.

Short answer: a donor survey is the cheapest market research a charity can do, and most charities never do it. You are guessing, constantly, about why people give to you, what they want to hear from you, and what would make them give again - and your donors already know the answers and would happily tell you if you asked. A short, well-made survey turns that guesswork into fact. It tells you which stories move people, how often they want to hear from you, what almost stopped them giving, and how they found you in the first place. It costs nothing but a free form and a little courage, and the act of asking is itself a form of respect that donors notice. But a survey is only worth running if you plan to act on what it says, because nothing damages trust faster than being asked for your opinion and then watching nothing change. Here is what to ask, how to get answers, and what to do with them.

Why ask at all

Start with the mindset, because it decides whether the survey is worth running. Most charities operate on assumptions about their donors - assumptions formed years ago, rarely tested, and quietly wrong in ways that cost real money. You assume people give because of your annual gala; they actually give because of one story they read three years ago. You assume they want monthly updates; half of them find the volume tiring and the other half wish you wrote more. You are making decisions about appeals, cadence, and content on a foundation of hunches.

A survey replaces hunches with evidence from the only people whose opinion counts. It also does something a spreadsheet cannot: it makes donors feel consulted rather than merely solicited. Being asked "what do you think?" instead of only "will you give?" is a small act of respect, and respect is the currency of donor retention. Even donors who never open the survey notice that you sent one, because it signals a charity that listens. The information is valuable; the gesture of asking is valuable too. Both are available to you for the price of a free form and a well-written email.

Keep it short, or nobody finishes

The single biggest mistake charities make with surveys is greed - trying to learn everything in one form, building a twenty-question monster that exhausts people three questions in and gets abandoned. A long survey does not gather more data; it gathers less, because the drop-off is brutal and the few who finish are unusual in ways that skew your results.

Discipline yourself to the questions you will actually use. Before adding any question, ask: what decision will this answer change? If you cannot name a decision, cut the question. Five to eight good questions that people finish beat twenty that they abandon. Tell people up front how long it will take - "three quick questions, two minutes" - and mean it, because an honest, small ask gets a far higher response than a vague one. Mix a few multiple-choice questions, which are fast to answer and easy to count, with one or two open text boxes where people can say what is really on their mind. And put the easy questions first and anything sensitive last, so that even a partial response leaves you with something useful. Short is not a compromise here; short is what makes the survey work at all.

The questions worth asking

Now the substance. A few questions earn their place in almost any donor survey because the answers change what you do. Ask why they first gave to you - not in the abstract, but the actual reason, because it reveals which of your messages truly moves people and which you only assume does. Ask how they first heard about you, which tells you where your real supporters come from and where to spend your limited effort finding more.

Ask what they most want to hear about from you, and how often, because this reshapes your communications directly: it tells you whether your newsletter is landing at the right rhythm or wearing people out. Ask, gently, what almost stopped them giving, or what would make them give more - the honest friction and the honest motivation, both of which you are otherwise guessing at. One open-ended question is worth including: "Is there anything you wish we did differently?" People will tell you things in that box that you would never have thought to ask, and some of them will be the most valuable sentences in the whole exercise. Avoid loaded or leading questions that fish for the answer you want ("How much did you love our gala?"), because they corrupt the data and waste the trust you spent getting the response. Ask plainly, and be ready to hear things you would rather not.

Getting people to actually respond

A survey nobody answers teaches you nothing, so treat response rate as a design problem rather than luck. The mechanics matter. Send it by email to people who already know you, with a subject line that is honest about what it is and how little time it takes. Explain briefly why you are asking and, crucially, what you will do with the answers - people respond far more readily when they believe their input will actually be used rather than filed.

Make it frictionless: a single link straight into a form that works on a phone, no login, no app, nothing to download. Every extra step sheds respondents. Consider keeping it anonymous, or offering that option, because anonymity often produces more honest answers, especially to the awkward questions - and honesty is the whole point. You do not need an incentive, and a prize can even distort your sample by attracting people who only want the prize, but a warm, personal tone and a sincere "your view genuinely shapes what we do next" tends to lift responses more than any reward. Send one gentle reminder to non-responders a week later, since many people mean to reply and simply forget, and then close the survey rather than letting it drift. A clear open-and-close window also gives you a clean set of results to actually work with.

Do something with the answers

This is where most surveys die, and it is the part that matters most. Data sitting in a spreadsheet changes nothing. The point of asking was to act, so read the responses properly - count the multiple-choice answers to see the patterns, and read the open text carefully, because the specific sentences are often where the real insight hides. Look for the things several people say independently; those are your signal.

Then change something visible, and change it soon. If people say your emails are too frequent, ease off, and if they want more impact stories, write them. Even one clear improvement is worth the whole exercise. And close the loop with your donors, because this is the step that compounds trust: tell them what you heard and what you are doing about it. "You told us you wanted to hear more about the people behind the numbers, so here is a new story each month" turns a survey into a relationship. It shows supporters that speaking up actually moved something, which makes them far more willing to engage the next time you ask - and it is close cousin to the discipline of thanking donors well, because both prove that you were genuinely paying attention. A survey you act on and report back on builds trust twice: once by asking, and once by responding. A survey you ignore quietly teaches people that their voice does not matter to you, which is worse than never having asked at all.

Frequently asked questions

How many questions should a donor survey have?

Fewer than you want to include - aim for roughly five to eight. A long survey does not gather more data; it gathers less, because most people abandon it partway and the few who finish tend to be unusual in ways that skew your results. Before adding any question, ask what decision the answer will change, and if you cannot name one, cut it. Tell people honestly how long it will take, put the easy questions first and anything sensitive last, and mix a few quick multiple-choice items with one or two open boxes. Short is not a compromise or a sign you are not serious; it is the thing that makes the survey get finished, which is the only version that teaches you anything.

Should donor surveys be anonymous?

Anonymity, or at least the option of it, usually produces more honest answers - especially to the uncomfortable questions like what almost stopped someone giving, or what they wish you did differently. Since honesty is the entire reason to run a survey, that candour is worth protecting. The trade-off is that you cannot connect an anonymous answer to a specific person's giving history, so if you genuinely need to link responses to records, say so plainly and explain why. A reasonable middle path is to keep the survey anonymous by default but invite people to leave their name if they are happy to be contacted about their answer. Whatever you choose, be transparent about it, and handle whatever people tell you with care and respect.

How do we get more people to respond?

Treat response rate as something you design for, not something you hope for. Send the survey to people who already know you, with an honest subject line about what it is and how little time it takes, and explain what you will actually do with the answers - people respond far more readily when they believe their input will be used. Make it a single frictionless link that works on a phone with no login. A sincere, personal tone tends to beat any prize, which can even distort your sample by drawing people who only want the reward. Send one gentle reminder to non-responders about a week later, since many people mean to reply and simply forget, then close the survey so you have a clean set of results.

What is the biggest mistake charities make with surveys?

Asking and then doing nothing. A survey sitting unread in a spreadsheet changes nothing and, worse, quietly teaches the people who took the time to reply that their voice does not matter to you - which erodes more trust than never asking would have. The fix is to plan the action before you send the questions: read the responses properly, look for the things several people say independently, change at least one visible thing soon, and then tell your donors what you heard and what you are doing about it. Closing that loop turns a survey into a relationship and makes people far more willing to engage next time. Ask only what you are prepared to act on, and then actually act on it.
