You raised the money. Somebody wrote a check, clicked a button, or handed you cash at the bake sale table. What you do in the next few weeks decides whether that person ever gives to you again. That work is donor stewardship: how you thank, report back to and stay in touch with donors after a gift, so they give again.
Most organizations are losing this part. Across the sector, fewer than half of donors give again the following year: 43.3% in 2025, according to the Fundraising Effectiveness Project’s 2025 results. Its organizers call turning a first gift into a second the most consequential problem in the donor pipeline that the sector has not yet solved.
This guide is for the small Miami County nonprofit, church group or volunteer committee with one paid person or none. It lays out a stewardship plan you can run from a kitchen table, the three numbers worth tracking, and what a local funder reads when you ask it for support.
What Donor Stewardship Is, and What It Isn’t
Donor stewardship is everything you do after a gift arrives: thanking, reporting back, keeping in touch, and treating the donor as a partner rather than a wallet. It runs until you ask again, and then it starts over.
It is easy to confuse with cultivating donors, which is the work before a gift: introducing people to your cause, inviting them to see it, getting to know them. Cultivation earns the first gift. Stewardship earns the second.
Stewardship is also not a gift shop. Mugs, tote bags and plaques are recognition, and they can be nice. What keeps people giving is evidence that their money did something.
A good benchmark is the Donor Bill of Rights, written by the Association of Fundraising Professionals, the Association for Healthcare Philanthropy, CASE and the Giving Institute. Read it as a stewardship checklist. Donors are entitled to know how their gifts will be used, to be assured the money goes where they gave it, and to receive appropriate acknowledgment and recognition. Deliver those three things reliably and you are already ahead of most organizations.
Why Donor Retention Matters More Than Finding New Donors
Donor retention is the share of last year’s donors who give again this year. It is the number that tells you whether stewardship is working.
Small organizations tend to pour their energy into new donors: the event, the new mailing, the social media push. That is understandable, and it is also the expensive half of fundraising. Every donor you lose has to be replaced before you can grow at all.
The national picture shows the squeeze. In 2025, total dollars raised went up while the number of donors fell an estimated 3.6%. Retention of first-year donors stayed essentially flat. Organizations are raising more from fewer, larger givers, and struggling to keep new ones.
The hopeful part is the pattern inside the data. The more times someone has given, the more likely they are to keep giving. In the Fundraising Effectiveness Project’s first-quarter 2026 figures, donors who gave once the year before had been retained at 7.4% so far that year, while donors who gave seven or more times stood at 88.1%. Those are early-year numbers, but the gap is the point.
For a small organization the arithmetic is simple. Every donor you keep is one fewer you have to find next year just to stand still. The second gift is the one to plan for, and that is what a stewardship plan does.
A Donor Stewardship Plan a One-Person Office Can Run
A donor stewardship plan is a short written schedule: what each donor hears from you, and when, after they give. It does not need software. A spreadsheet with a date column works fine.
Here is a plan built for an organization where one person does everything.
| When | What | Who gets it |
|---|---|---|
| Within 48 hours | A thank-you note or call | Every donor |
| Within 30 days | What the gift did | Every donor |
| Around 90 days | An update with no ask | Every donor |
| Before the next appeal | A personal note | Anyone who has given twice or more |
| On the anniversary | A short “a year ago” note | First-time and memorial donors |
Within 48 hours: say thank you
Thank the donor by name, mention what they gave to, and sign it as a person. A handwritten line on a plain letter beats a perfect letter that goes out three weeks late.
Mind the paperwork too. For any single gift of $250 or more, the donor needs a written acknowledgment from you to claim a deduction.
Under the IRS written acknowledgment rules, it must name your organization, state the cash amount or describe (without valuing) a non-cash gift, and say whether the donor received anything in return. Many small groups simply build this into the thank-you letter. The IRS’s Publication 1771 has sample wording.
Within 30 days: show what the gift did
Report in units, not causes. “Your gift bought a week of groceries for a family” sticks. “Your gift supports food security” does not. If the gift went into a larger pool, say what the pool did.
It is the same habit behind the digital fundraising campaigns that actually work: one concrete unit of impact the donor can picture.
Around 90 days: an update with no ask
Send one short email or postcard: a photo, a sentence about something that happened, a thank-you. No donate button.
This is the touch most organizations skip, and it is the one donors remember. It proves you were not only writing when you wanted something.
Before the next appeal: a personal note
Before your year-end letter goes out, write a line by hand to everyone who has given twice or more. They are your most loyal supporters and the most likely to give again. They should not hear about the appeal from a form letter first.
On the anniversary: a reason to remember you
A note on the anniversary of a first gift takes five minutes and lands harder than almost anything else you send. For memorial gifts especially, the family will notice that you remembered.
Donor Stewardship Ideas That Cost Almost Nothing
You do not need a budget to steward well. Some of the best donor stewardship ideas are free:
- Board thank-you calls. Give each board member a few names a month to call, just to thank. Keep expectations modest: a field experiment with about 500,000 new donors found thank-you calls alone had no measurable effect on whether they gave again. Treat calls as a courtesy, and put your effort into showing donors what their gift did.
- Volunteers to donors. Your volunteers already know what you do. Thank them the way you would thank a donor, and invite them to give at the end of a season rather than the start.
- A handwritten line. Add one sentence in ink to every printed letter.
- A photo, not a report. One picture from the work, sent by text or email, can say more than a page of results.
- Ask why they gave. Write the answers down. They are your best appeal copy next year.
- Respect the mailing list. The Donor Bill of Rights gives donors the right to be taken off any list you plan to share. Honor it the first time they ask.
These pair naturally with the fundraising ideas that work without staff. A structured board ask and a monthly giving option both depend on donors who feel looked after.
Stewarding a Funder: What the Foundation Reads
Stewardship applies to funders too. A community foundation is a donor with a board.
If your organization works in Miami County, here is how the Miami County Community Foundation considers a request. There is no application form and no grant cycle.
Executive Director Tammy Booe puts it plainly: “That is a feature, not a gap. We do not have a form.” The reason is scale. The Foundation is not yet big enough to run a grant cycle.
The email is the application. It should cover:
- what the project is, and what it will do in Miami County
- how much you are asking for
- whether your organization is a 501(c)(3)
- who is asking, and how to reach you
Requests are accepted year-round, and a decision comes about a month after the Foundation receives your email. There is no fixed amount; it depends on the project. As Tammy puts it: “Do you want five Bibles or do you want 500 Bibles?”
Three programs are published, and each sets its own eligibility: Avelyn SonShine Journey, Shifting Gears and Stomp Out Suicide. Beyond those, the board considers other projects case by case. The project has to take place in Miami County, though the people running it do not have to live there. The details, and where to send your email, are on the Foundation’s grants page, linked at the end of this guide.
One language note is itself a stewardship lesson. The Foundation calls much of what it pays out donations or contributions. “We don’t call them grants,” Tammy says. “We call them donations or contributions.” Use a funder’s own words when you thank them.
Then thank them the way you would thank any donor: within days, and again when you can say what the money did. If you are drafting that first email, here is how to write the email that replaces a grant proposal.
Measuring Donor Stewardship: Three Numbers to Track
You cannot improve what you do not count, but a small organization only needs three numbers to see whether its donor stewardship is working.
- Donor retention rate. Donors who gave last year and again this year, divided by everyone who gave last year. If half of last year’s donors gave again, your rate is 50%.
- First-time donor retention. The same calculation, counting only people whose first gift came last year. This is where stewardship shows up first.
- Time to second gift. The months between a donor’s first and second gift. If that number is shrinking, your plan is working.
Check all three once a year, in January, and put them on the first page of your board packet. The national 43.3% is a rough yardstick, but your own trend matters more than anyone else’s average.
FAQ: Donor Stewardship
How soon should you thank a donor?
Within 48 hours is a good standard for a small office. Speed matters more than polish. For any single gift of $250 or more, make sure the written acknowledgment the IRS requires goes out with it or soon after.
What is the difference between donor cultivation and donor stewardship?
Cultivation is the work before a gift, getting to know someone and showing them your cause. Stewardship is the work after every gift: thanking, reporting back and keeping in touch. Cultivation earns the first gift; stewardship earns the next one.
How do you calculate donor retention rate?
Divide the number of last year’s donors who gave again this year by the total number of last year’s donors. Multiply by 100 for a percentage. Run it separately for first-time donors to see where you are losing people.
What should a donor stewardship plan include?
Who hears from you, what they hear and when. At minimum: a thank-you within days, a note on what the gift did, an update with no ask, a personal note to repeat donors before your next appeal, and a simple way to track who got what.
Conclusion
Donor stewardship is not a program you add once you have staff. It is a calendar of small promises kept: a thank-you on time, a report on what the money did, a note that asks for nothing. Organizations that keep them stop spending every year replacing the donors they lost.
Start with one promise this month. Thank every donor within 48 hours, and write down the date you did it. If you are still getting set up, how to start a nonprofit in Miami County covers the groundwork first.
