Nonprofit Donor Communications Are Marketing (Whether You Call It That or Not)

Heading into your annual appeal? Donor letters, volunteer asks, and thank-you notes are marketing. Here’s how to treat them that way, mission first.

September is when annual appeal letters start taking shape. Development directors are pulling donor lists, drafting copy, and choosing a mail date. And somewhere in that process, someone usually says, “We’re not really a marketing organization.”

We’ve heard that from nonprofit leaders, and we understand it. “Marketing” can sound like selling, and selling can feel out of step with a mission. But your appeal letter, your volunteer recruitment post, and your January thank-you email all share one job: helping a real person decide to act. That is marketing, whatever you call it.

What Counts as Nonprofit Marketing?

Nonprofit marketing is any communication that asks someone to learn about, care about, or act on your mission. Donor letters, event invitations, volunteer recruitment, e-newsletters, social posts, and the donate page on your website all qualify. If it reaches an audience and asks for a response, it’s marketing.

Why Does This Matter Before Your Annual Appeal?

Here’s a quick look at where giving stands heading into the season:

Giving is up. Americans gave a record $617.2 billion in 2025, and individuals contributed about 64% of it (Giving USA 2026).

Donors are down. The number of donors fell 3.6% in 2025, the fifth straight year of decline, according to the Fundraising Effectiveness Project (FEP).

Retention is low. Overall donor retention was 43.3%, meaning more than half of the prior year’s donors did not give again (FEP).

December carries weight. Neon One data suggests roughly 17% to 22% of a nonprofit’s annual revenue arrives in December.

Simply stated: Fewer people are giving larger amounts. That makes every donor relationship worth more, and protecting relationships is exactly what a marketing plan is for.

Mission Messaging or Marketing Strategy?

Mission messaging explains why your work matters. A marketing strategy decides who hears that message, where, and what happens next. Many nonprofits have the first and skip the second.

The difference shows up in the copy. A general appeal might read: “Our organization has served the community for 40 years. Please give generously this holiday season.” A version written for a lapsed donor might read: “Two years ago, you helped us open the food pantry on Saturdays. We’d love to have you back as we work to add Wednesday evenings.”

PRO TIP: Write your appeal for one specific reader first, then adapt it for each donor group.

How to Plan Your Annual Appeal Like a Marketer

Start simple. These five steps work for a development office of any size:

Segment your list. At minimum, split donors into new, lapsed, and loyal. Each group needs a different message.
Give each piece one goal. One letter, one ask. Combining a donation request, a volunteer call, and gala tickets usually means none of them land.
Match the channel to the person. Some longtime supporters still prefer a printed letter with a reply envelope. Some younger volunteers may only notice you on Instagram or in their inbox.
Plan the follow-up before you send. Map out the reminder email, social posts, and December 31 last call now, while there’s still time.
Track results by segment. Use your donor database, (some of our clients use Bloomerang or DonorPerfect) or even a well-kept spreadsheet, so next year’s appeal starts smarter.

PRO TIP: Include a QR code on your letter to so younger audiences can act there, too.

Don’t Forget the Thank-You

With retention hovering around 43%, the thank-you may be the most important marketing piece you send all year. Send it quickly, make it personal, and tell donors what their gift made possible. Volunteers deserve the same care, since a volunteer who feels valued can grow into a donor, a board member, or your best advocate.

PRO TIP: Put a “no ask” donor update on the calendar for spring. It keeps the relationship warm between appeals.

Our Approach at Dunn Marketing

Our Empathy-Driven Brand Building™ process starts with the audience: what donors and volunteers care about, what they need to hear, and what would make them feel their support mattered. From there, we build the messaging, channel plan, and measurement around those people.

The Takeaway

If you leave with anything, let it be this: your supporters deserve a communications plan as thoughtful as your programs. Choose one donor group, one goal, and one follow-up, and build this year’s appeal from there.
