There are plenty of articles about how long a fundraising letter should be, what subject line to use, and when to send it. Those details matter, but they come after a more important question: What should you say?
Your year-end appeal may start as a letter, but donors could encounter it in an email, on social media, through a text message, or on your donation page. Each format calls for different wording. The message behind them should be the same.
Let’s focus on the three things that make that message work: who it’s about, what it says, and how you say it.
Focus on the Donor
Your year-end appeal is about your donors, not your nonprofit. It should remind them why their support matters and show them what they can help make possible next.
That doesn’t mean pretending your organization does no work. It means giving donors their proper place in the story. Their gifts don’t exist to support a list of organizational accomplishments. They help people, communities, or causes your organization serves.
An impact story can make that connection clear. Choose one specific example, explain what changed, and show how donor support contributed. Keep the person at the center of the story as a person, with dignity and agency, rather than presenting them only as a problem your nonprofit solved. Get permission before sharing identifying details, or use a clearly described composite example when appropriate.
Compare these two openings:
“This year, our organization expanded three programs and served more people than ever before.”
“When families in our community needed help finding a safe place to stay, supporters like you helped make sure someone was there to answer the call.”
The first opening may be true, but it starts with the organization. The second gives donors a reason to keep reading. Your own version should use the people, work, and details that are true to your mission.
Get Specific with Your Message
Here’s a useful test from the original annual appeal advice: If you removed your nonprofit’s name, would a donor still recognize the message as yours? If any organization could send it, it needs more detail.
Start with one clear need or opportunity. Explain what donor support has already helped accomplish, what still needs to happen, and what a year-end gift can help do. Use a number or example when it adds meaning, but don’t make donors work through a page of statistics to find the point.
A strong appeal usually gives readers a simple path:
- Open with a person, moment, or need that connects to your mission.
- Show what donor support makes possible with a specific example.
- Explain what’s needed now and why this is the time to give.
- Ask clearly for a gift.
- Make giving easy and thank donors for considering it.
Your call to action should tell people what they are being asked to do. “Please make a year-end gift today to help more families access [specific service]” is clearer than “Support our mission.” If you suggest a gift amount, connect it to a real, supportable use of funds. Avoid promising that every gift will produce an exact result unless that claim is accurate.
Adapt the Appeal to Each Channel
A coordinated campaign shouldn’t mean pasting the same letter everywhere. It means carrying the same story, need, and ask into the places your donors will see them.
Direct mail gives you room to build the story. A letter can feel personal, particularly when it acknowledges a donor’s relationship with your organization. Make the request easy to find, include a clear way to respond, and check that the reply options match what the letter promises.
Email needs to get to the point sooner. Your subject line should give someone a reason to open it, and your first lines should make sense without a long introduction. Keep the central ask visible and link directly to the relevant donation page. A follow-up email can share another part of the story or a timely reminder without repeating the first email word for word.
Your donation page should continue the conversation. If an email asks donors to help fund a particular program, the page they reach should explain that same need. A generic page with no connection to the appeal can make donors wonder whether they clicked the right link.
Social media can introduce the story. One useful detail, a short explanation of the need, and a link to give are often enough. A post should make sense to someone seeing your organization for the first time.
Text messages should be brief and recognizable. Identify your organization, state the ask plainly, and link to the right page. Send texts only to people you’re permitted to contact through that channel, and respect their preferences.
Before anything goes out, read the pieces together. Would a donor who receives the letter, sees a post, and opens an email understand that they’re part of the same appeal?
Make It Personal, but Get the Details Right
Using someone’s first name is a start. Knowing what you want to say to that person is more valuable.
A first-time donor might need to hear what their initial gift helped begin. A longtime donor may appreciate a direct acknowledgment of their continued support. Someone who gave last year but hasn’t yet given this year may respond to an update that reconnects them with the work they cared about. For a donor with a close relationship to your nonprofit, a personal note or call may be more appropriate than another mass email.
You don’t need dozens of versions. Even a few thoughtful groups can make your appeal more relevant. Review giving history, interests, and contact preferences before sending, and make sure your records won’t lead to an awkward message. Thanking someone for a gift they didn’t make, or asking a donor to give again immediately after they gave, works against the connection you’re trying to build.
If your lists need attention, start there. Clean donor data helps you reach the people you meant to reach and personalize your year-end outreach accurately.
Lose. The. Jargon.
We can’t say this strongly enough. Insider language may be familiar to your staff, but it can put distance between you and a donor. Acronyms, program names without explanations, and phrases like “make a difference” ask readers to fill in too much for themselves.
Write the way you would explain the work to someone who cares about your cause but doesn’t work in your field. Tell them what happened, what needs to happen next, and how they can help.
Then read your appeal aloud. Does it sound like a person speaking to another person? Is the ask unmistakable? Does the message still sound like your nonprofit wherever it appears?
Your year-end appeal is one of the most important conversations you’ll have with donors this year. Make it specific. Make it clear. Above all, help donors see the role they can play.
