Thank You Is More Than Good Manners: Why Donor Stewardship Matters
Sharon and I did a Zoom training today on Giving Tuesday for one of our clients.
As you can imagine, we talked about a lot of things: making the ask, telling a compelling story, making it easy to give, engaging your Board, using social media, and of course what happens after someone clicks that DONATE button.
We were talking about the importance of thanking donors, both individuals and businesses, when a participant asked an important question:“How should my organization be thanking an anonymous donor?”
It’s a great question.
And it made me think about all of the reasons that we thank our donors—and why a sincere thank you can have a much bigger impact on fundraising success than simply being polite.Because here’s the thing:Fundraising is not a transaction.
It’s a relationship. And relationships need to be nurtured.
A donor should never feel like the only time they hear from you is when you need something.So, let’s talk about why saying THANK YOU is such an important part of your fundraising strategy.
Yes, There Are Tax Requirements
Let’s start with the practical piece.For certain charitable contributions, donors need written acknowledgment from the organization to substantiate their charitable deduction. For example, the IRS generally requires a contemporaneous written acknowledgment for a contribution of $250 or more. That acknowledgment includes information such as the amount of a cash gift, a description of non-cash property, and whether the donor received goods or services in return.
So yes, your acknowledgment letter, email, or receipt has an important administrative purpose.But please don't confuse a tax receipt with a thank you.
A tax receipt says:“We received your $500 contribution.”
A good thank you says:“Your $500 contribution is helping us do something meaningful.”See the difference?
One documents the transaction.
The other begins or continues the relationship.
There are some additional considerations with gifts made through donor-advised funds (DAFs) or Foundations. Make sure you are looking carefully not only at the donor’s name - but at how they’ve chosen to make their gift.
The lesson for nonprofits? Know where the gift came from, know what acknowledgment is appropriate, and don't let your automated tax receipt be the only communication your donor receives.
Thank Them AND Share the Impact
This is where the magic happens.Your donor gave because they care about your mission.They may have given $25 or they may have given $25,000.They may have given because someone they love has been helped by your organization. Maybe they attended an event. Maybe a friend asked them. Maybe they saw a story on social media.Whatever brought them to you, their gift is an opportunity to bring them closer to your mission.
So don't just say:“Thank you for your generous donation.”Tell them what their support makes possible.
Did their gift help provide meals?
Support a child?
Keep an animal safe?
Fund a scholarship?
Give someone access to healthcare?
Keep a critical program running?
Tell them!
Your donors want to know that their generosity matters. Give them a reason to feel good about saying YES.
Thanking Donors Can Help You Find MORE Donors
Here is another reason we love a good thank you:It gives you something to talk about.
Your thank-you communication doesn't have to be a private transaction between your organization and one donor. With appropriate permission and respect for donor privacy, you can use gratitude to tell your broader community what is happening.
Now you've done two things.You've thanked the people who supported you.And you've shown everyone else that people are supporting you.
Social proof matters.
When potential donors see that other people believe in your mission, they may be more likely to stop, learn more, share your story, or make a gift themselves.
Today’s thank you can become part of your next fundraising story.
Don't Forget Your Corporate Partners
Businesses are donors, too.And sometimes (or always) the relationship with a business is a little different.A corporate partner may be supporting your organization because they believe deeply in your mission. They may also have specific marketing, visibility, employee engagement, or community-relations goals. That means your thank you should recognize the partnership—not simply the check.Did they sponsor an event?
Thank them publicly.
Did their employees volunteer?
Show them the impact.
Did they help you reach a new audience?
Tell that story
Did they provide funding for a specific program?
Share the results.
And if you've agreed to provide recognition as part of the partnership, do it!
Make sure logos are correct. Make sure signage is visible. Tag the company when appropriate. Provide photos they can use. Give them the information they need to share their community investment internally and externally.
Corporate engagement in your work should feel like a partnership.
But What About the Anonymous Donor?
Now let's go back to the original question.
“How do I thank an anonymous donor?”
Sometimes “anonymous” doesn't mean you don't know who the donor is.
You may know exactly who made the gift—but the donor has chosen not to have their name shared publicly or included in donor recognition.
And that's perfectly okay.
In fact, respecting a donor's wishes is part of good donor stewardship.
You can still thank them personally. You can still share the impact of their gift. You can still keep them informed about the work their generosity is making possible.
What you shouldn't do is publicly acknowledge them if they've asked you not to.
So, instead of putting their name in your annual report, on your website, at your event, or in a social media post, you might say:
“We are incredibly grateful to one of our generous supporters who has chosen to remain anonymous. Their generosity is helping us…”
Or simply recognize them privately:
“Thank you for your generous support. We know you have chosen not to be publicly acknowledged, and we want you to know how much we appreciate your commitment to our mission. Because of your generosity…”
And here's the important part:
Anonymous does not mean unappreciated.
In fact, a donor who chooses to remain anonymous may be giving you an opportunity to demonstrate just how well you understand donor stewardship.
Honor their wishes.
Thank them personally. Learn more about what prompted their generosity.
Share their impact.
And continue building the relationship—just without putting their name in the spotlight.
Because sometimes the most meaningful thank you is the one that happens quietly, directly, and sincerely.
Don't Make Thanking Donors One Person's Job
This is one of our favorite fundraising lessons: Everyone in your organization is a part of the fundraising team … Everyone can say thank you.
Your Executive Director can make a call.
Your Board member can send a handwritten note.
Your program staff can share a story.
A volunteer can make a personal connection.
Your development team can send the formal acknowledgment.Y
our social media team can share the collective impact.
Your CEO can call a major donor.
There are so many opportunities to make donors feel seen and appreciated.And saying thank you is often a much easier way to get your Board and volunteers involved in fundraising.They don't have to ask for money.They don't have to make a pitch.
They just have to say:“Thank you for believing in this work.”
That's fundraising, too.
Remember: The Donor Cycle Is a Circle
We often talk about the donor cycle: identify, cultivate, solicit, steward, and eventually ask again.
There’s a reason it’s a circle and not a straight line.
The thank you piece of stewardship isn't the end of the process—it’s what keeps the relationship moving.
So don't just thank your donors because it's the right thing to do. Thank them because gratitude, communication, and stewardship are what bring donors back around the circle.
And that's how one gift can become a lasting relationship.
The Bottom Line
We spend so much time talking about how to get the gift.We should spend just as much time thinking about what happens after we receive it.Because every donor is a potential long-term partner.
Every gift is an opportunity to deepen a relationship.Every thank you is an opportunity to tell your story.And every story is an opportunity to bring someone closer to your mission.So, whether your donor gave $10, $10,000, or $100,000…Whether they are an individual, a business, a foundation, or a donor-advised fund…Whether you know their name or they chose to remain anonymous…Say thank you. Say it quickly.Say it sincerely.Say it more than once.
And, most importantly, tell them what their generosity made possible.
Because the best thank you isn't just:“Thank you for your gift.”It's:“Thank you for believing in what we do. Look what we are accomplishing together.”And THAT is where fundraising relationships begin to grow.
