Acknowledgment Letter

A written thank-you and receipt a nonprofit sends a donor to recognize a gift and document it.

An acknowledgment letter is the written communication a nonprofit sends to a donor to thank them for a gift and serve as a record of the donation. It plays a dual role: it is both an expression of gratitude and, when it includes the required details, a receipt the donor may use for tax purposes.

For donations above certain thresholds, the IRS expects donors to have written acknowledgment that includes specific information, such as the amount and a statement about whether any goods or services were provided in return (see quid pro quo contributions). The exact requirements depend on the gift, so organizations should follow current IRS guidance.

Beyond compliance, a prompt and warm acknowledgment is a cornerstone of donor stewardship and a meaningful driver of retention. Automating receipts while keeping them personal is a core CRM capability.
