How to write a donor thank-you letter (with examples)

What to put in a donor thank-you letter, how fast to send it, and short examples a small nonprofit can adapt for first-time, monthly and major donors.

A thank-you letter is the cheapest fundraising you'll ever do. Donors who get a prompt, personal thank-you are much more likely to give again, and most small nonprofits don't have a donor problem as much as a "second gift" problem.

Here's how to write one that people actually read.

Send it fast

Aim for within 48 hours of the gift. A week is fine. A month feels like a form letter, even if it isn't. If you can't send a full letter quickly, send a short email the same day and follow with a letter or card.

What every thank-you letter needs

  1. Their name, spelled right. "Dear Maria," not "Dear Friend."
  2. The gift, named. "Your gift of $50" or "the box of winter coats you dropped off on Tuesday."
  3. What it does. One concrete sentence about the result. "That covers a week of after-school snacks for 12 kids."
  4. A real person signing. Your name, your role, and ideally a handwritten line or signature.
  5. Tax details, if it's a receipt. The amount, date, your organization's legal name and EIN, and a statement that no goods or services were provided in exchange (or a description of what was). If you send receipts separately, keep the thank-you warm and the receipt short.

What to leave out: another ask, jargon ("leveraging capacity"), and long paragraphs about your organization's history.

Keep it short

Three short paragraphs is plenty. A letter someone reads in 30 seconds beats a page they skim.

Example: first-time donor

Dear Maria,

Thank you for your gift of $50 to Northside Pantry on October 12. It was your first gift to us, and we're really glad you're here.

Your $50 stocks a family's weekend food bag for a month. This Saturday, one of those bags goes home with a mom of three who started coming to us in September.

If you ever want to see the pantry on a Saturday morning, just reply to this letter. We'd love to show you around.

With thanks, Dana Lee, Volunteer Coordinator

Example: monthly donor

Dear James,

Six months ago you started giving $15 a month to Riverbend Literacy. I wanted to stop and say thank you.

Because of steady gifts like yours, we could promise our tutors a full school year instead of a semester. That's 40 kids with the same reading buddy from fall to spring.

Thank you for sticking with us.

Warmly, Ana Ruiz, Director

Example: larger gift

For bigger gifts, a phone call within a day or two matters more than the letter. Call first, then send a letter that mentions the call and gets specific about the project the gift supports.

Example: in-kind gift

Dear Ms. Patel,

Thank you for the 30 winter coats you brought to the shelter on November 3. They were on kids' backs by Friday.

For your records: we received 30 new children's coats. No goods or services were provided in exchange for this gift. Northside Shelter, EIN 12-3456789.

Gratefully, Tom Becker, Shelter Manager

Make it personal without spending your evenings on it

The hard part isn't knowing what to say. It's doing it 40 times after a busy Giving Tuesday. A few habits help:

  • Write two or three short "what your gift did" sentences each month and reuse them.
  • Keep notes on donors: first gift, how they found you, what they care about.
  • Split the work. A board member can make thank-you calls.

Donor Thank-You drafts a personal note for each donor from a few details, and you review and approve every note before it goes out. The free plan covers 10 notes a month.

A simple thank-you checklist

  • Sent within 48 hours
  • Name and gift amount correct
  • One sentence on what the gift does
  • Signed by a real person
  • Receipt details included or sent separately
  • Donor notes updated
