You want to thank donors personally. But who makes the calls? What should they say? Should you use a staff member, a recorded message, or an AI voice agent? And what happens when someone asks a question? If your team is small, those decisions matter.

A good donor thank-you call has one job: make someone feel noticed without turning gratitude into another ask. You also need a simple way to record a response and follow up. This guide shows you where to start.

Here’s what you’ll learn:

• What research says about donor thank-you calls

• Which type of call to use and when

• Short scripts and a small-team launch checklist

• What a university changed about calling

• What to track after you make calls

Let’s dig in.

What the evidence really says about thank-you calls

Researchers Anya Samek and Chuck Longfield ran field experiments involving roughly 500,000 new donors, randomly assigning them to receive a thank-you call or not. Their 2023 paper in the American Economic Journal: Applied Economics found no measurable effect of these standard thank-you calls on donor retention.

The result matters: you shouldn’t promise leadership that a thank-you call will automatically increase giving. That doesn’t mean gratitude is pointless. The study looked at common calling practices, and timing and purpose can differ from your plan.

A useful call may give a donor a chance to ask a question or tell you why they care about the mission. Measure whether your team listened and completed requests, not just whether someone answered.

Three types of donor calls: Personal, prerecorded, and AI voice

Three types of calls are common. A personal call connects the donor with a staff member or volunteer. A prerecorded robocall plays a recorded message. An AI voice call can listen and answer within a set of approved topics. They are not interchangeable.

Choose the caller based on what the donor needs. If a conversation may be personal or sensitive, start with a person. If you only need to share a simple detail, an approved automated call may work. Compare the options below.

Personal calls: Let a human lead when judgment matters

Use a person when the donor has a close relationship with your organization, has a sensitive question, or requests to talk. A live caller can listen and respond. The tradeoff is time: a small team cannot hold hundreds of personal conversations in an afternoon.

Prerecorded robocalls: Deliver a consistent, one-way message

A prerecorded call plays the same approved message. It may work for a simple event reminder or update, where permitted. It cannot handle a real conversation. Don’t use it for a sensitive gift question or a donor who needs staff help.

Conversational AI voice calls: Handle structured interactions

An AI voice agent can share an approved thank-you, answer simple questions, and flag requests that need staff. This can help with routine appreciation or event invitations when the outreach is permitted. But the agent must clearly identify itself, follow approved guidance, and hand off sensitive questions to a person.

One important legal distinction: although a prerecorded message and a conversational AI call behave differently, the FCC’s 2024 AI voice ruling treats AI-generated voices as artificial or prerecorded voices under the TCPA. Calling permissions, exemptions, identification, opt-outs, and other rules must be assessed for the actual campaign; nonprofit status alone is not blanket permission.

Which type of donor call should you use?

Use this table to choose a call type. “Best” means it usually fits the job. “Possible” means the situation needs clear limits and permission. “Avoid” means another approach will likely serve the donor better. The table is a planning tool, not legal approval.

The simple rule: use recorded calls for basic updates, conversational AI for suitable routine outreach, and people for questions that need judgment. Automation should help your staff spend more time with donors who need a real conversation.

Before choosing a format, review donor preferences, permitted calling methods, what the caller may share, and who will handle requests for personal attention. The FTC’s charity telemarketing guidance and the FCC’s AI voice ruling explain important compliance distinctions; qualified counsel should review the actual campaign.

Use a decision test before assigning a call

You don’t need to call every donor. Start by asking whether the call would be useful to the person receiving it.

Before you build a calling list, answer four questions:

• Purpose: Can we name one honest reason for the call besides getting another gift?

• Relevance: Do we know enough about the gift or relationship to avoid a generic conversation?

• Permission and channel fit: Are we permitted to use this calling method, and does it fit the person’s preferences?

• Next-step ownership: If the donor asks for help or a staff member, who will respond?

If you cannot answer those questions, pause the campaign. A short email or a personal follow-up with a smaller group may be better than a large calling list.

Start with a 10-donor calling test

You don’t have to launch a campaign to learn what works. Choose ten eligible donors and test one clear thank-you. Use this simple checklist before you expand:

1. Confirm the gift and the donor’s calling preferences. Do not call a stale number or someone who has asked you to stop.

2. Choose the right caller. Use a person for personal or sensitive conversations. Consider approved automated outreach only for a routine, permitted message.

3. Prepare a 20-second opening, one optional question, and a polite way to end the call.

4. Assign one person to review replies and handle requests for receipts, program details, or a callback.

5. Review what happened after ten attempts. Count genuine conversations, requests completed, complaints, and staff time. Improve the experience before increasing volume.

If you cannot explain why you are calling or who will respond afterward, don’t press send or dial yet.

Four thank-you call scripts you can adapt

Use these examples to get started. Change the wording to match your organization and the donor’s actual gift. Verify names, dates, and contact permissions. Do not pretend these are transcripts from real donor conversations.

First-time donor: Make the gift feel noticed

“Hi [First name], I’m [Name] with [Organization]. I’m calling to thank you for your recent first gift. I don’t need anything from you today. I just wanted you to know we noticed and appreciate your support. If you have a moment, I’d love to hear what first connected you with our work.”

The final question is optional. If the person is busy or doesn’t want to answer, thank them and close. A brief positive interaction is more useful than a long, uncomfortable one.

Monthly donor: Recognize consistency without an upgrade ask

“Hi [First name], this is [Name] from [Organization]. I wanted to thank you for your steady support. We appreciate having you alongside us month after month. Is there a kind of program update you’d find especially helpful?”

A monthly donor already has a continuing commitment. Asking them to increase their gift during a call framed as gratitude changes the conversation. If you want to discuss an upgrade, plan a separate, appropriate interaction.

Event donor: Connect the thank-you to the occasion

“Hi [First name], thanks for supporting [Event or Program]. We’re following up with a short update on what happened. Would you like me to send that to your preferred email?”

Only share confirmed results. Do not say their gift funded a particular outcome unless your records support that connection.

No answer: Leave a low-pressure message

“Hi [First name], I’m [Name] with [Organization]. I was calling to thank you for your recent support. We appreciate you. No need to return the call, but you’re welcome to reach us at [official contact method]. Have a good day.”

Use voicemail only when appropriate for the recipient and lawful for the calling method. Avoid naming private gift amounts or sensitive designations on a shared phone.

The thread connecting these examples is simple: gratitude should be useful even when it doesn’t lead to another transaction.

A real organization changed its calling model

Kent State University’s former phone center offers a more instructive example than a generic promise about call volume. In a 2025 CASE account of its redesign, the university described a 56% decline in new commitment dollars from its phone operation over five years. It replaced a highly transactional phonathon approach with a multichannel Alumni Engagement Center that opened in April 2023.

Kent State described non-solicitation work such as new-graduate care calls and World Gratitude Day stewardship calls. Its published account is about a redesigned human-led outreach operation, not evidence that AI calls raise more money.

The lesson I take from Kent State is not “make more calls.” It is “change what a call is for.” A channel that people associate only with repeated solicitations may become less effective. A call that has a specific, useful purpose can be part of a broader relationship model.

Make the response more important than the dial attempt

A completed call is not always a completed task. Someone may ask for a receipt, a program update, or a staff callback. Record the request and name the person responsible.

Record one clear outcome for every call:

• Reached and thanked: Record completion; no additional call needed.

• Asked for a program update: Send the approved resource through the chosen permitted channel.

• Requested staff contact: Assign a named person and due date.

• Asked to change preferences: Update the source-of-truth record and suppression lists.

• Declined or opted out: Honor the request and end the appropriate outreach.

• No answer or invalid number: Record the outcome; don’t treat silence as a request for repeated attempts.

Your goal is simple: someone on your team should be able to open the record tomorrow and know what to do next.

If your team needs a fuller workflow for organizing those moments, our guide to donor engagement explains why the next action matters more than the last message.

When should AI voice be involved?

If your team cannot personally call every eligible donor, start with one approved, narrow use case. For example, you might thank a group of first-time donors without asking for another gift. EverRaise Campaign Builder can draft the approved voice script, email, and follow-up messages in your organization’s brand voice and tone. For suitable campaigns, EverRaise AI Voice can make structured calls and flag requests for human follow-up. Your staff should review everything before use.

The FCC’s 2024 ruling on AI-generated voices confirms that certain AI voice calls fall under rules governing artificial or prerecorded voice calls. Whether a proposed charitable campaign is permissible depends on the number, calling method, purpose, consent, or applicable exemptions, and other requirements. Have qualified counsel review the proposed campaign.

Measure the right outcomes, then test your assumptions

Start with four numbers: calls made, meaningful replies, requests that staff completed, and opt-outs or complaints. If a donor asks for help, track whether the help arrived. An answer rate alone cannot tell you that.

If you want to learn whether calls improve giving, run a careful test with comparable eligible donor groups. Define the outcome and time period beforehand. Keep your reporting honest about sample size, selection, and whether differences could be due to chance.

A useful calling program should leave donors feeling respected and your records more accurate. If calls cost time but do not help donors or your team, change the approach rather than assuming more calls will fix it.

Frequently asked questions

The most common questions are really decisions about purpose, audience, and what the call should accomplish. Here are practical starting points to use with your own stewardship policy.

Do thank-you calls increase donor retention?

A major randomized field experiment found no measurable retention effect from standard thank-you calls. That does not settle every possible timing or use case. Be cautious about promising a retention lift without your own evidence.

Should small gifts receive a call?

A small gift can be meaningful. Choose calling segments based on the conversation’s purpose, preferences, capacity, and likely value to the donor, not only gift size.

How long should a thank-you call be?

Long enough to express real gratitude and respond appropriately, but never longer to meet a target. Some supporters may want to talk; others will appreciate a brief acknowledgment.

The call is successful when you keep the promise

Start small. Choose ten donors whose contact preferences allow the planned call. Prepare a genuine thank-you, decide who handles replies, and test the experience before you expand.

You don’t need a giant call list to begin. You need a useful reason to call, an approved method, and a team member who owns the next step. Fix those basics before you increase call volume.
