Lapsed Donors: How to Find, Segment and Win Them Back

An animal rescue had 1,150 donors in 2025. On October 1, 2026, it pulls a list: 640 of them haven't given yet this year. Some will give in December as usual. Others stopped months ago and will never hear a reason to come back unless someone reaches out. The year-end appeal is six weeks away, and the question is which of those 640 people to contact, how and with what message.

A lapsed donor is someone who used to give and has stopped, measured against a time window you define. Winning lapsed donors back often costs less than finding new ones, because they already know you and chose you once. It works best as a planned sequence: define lapse, clean and segment the list, send a short series of messages that lead with gratitude and impact, then measure what came back.

This guide covers the definitions, including LYBUNT and SYBUNT, why donors stop, how to segment them, a win-back sequence with templates, reactivation offers that don't rely on gimmicks, and how to measure results.

What Counts as a Lapsed Donor

There's no single official definition, so write down your own and use it consistently. Most organizations measure lapse by fiscal year.

• LYBUNT ("last year but unfortunately not this year"): gave in your previous fiscal year but not yet in the current one. During the year, LYBUNTs are really at-risk donors; after the year closes, they're lapsed.
• SYBUNT ("some year but unfortunately not this year"): gave in an earlier year, but neither last year nor this year so far. Some organizations include LYBUNTs in SYBUNTs; it's clearer to keep them separate.
• Lapsed monthly donor: a recurring gift that stopped because the donor canceled or a payment failed and wasn't restarted.

Lapse Stages

Here's how the animal rescue's file looks on October 1, 2026, with a calendar fiscal year.

The further back the last gift, the lower the response and the lower your spending per donor should be.

Why Lapse Deserves Attention

The Fundraising Effectiveness Project, which tracks giving data across US nonprofits, reported overall donor retention of 43.3% for 2025, while the number of donors fell 3.6% (AFP, April 21, 2026). Its Q2 2026 update found that only 11.3% of donors acquired in 2025 had given again by the end of June 2026, and that donors who gave seven or more times in 2025 were retained at 90%, compared with 14.4% of one-time donors (AFP, October 29, 2026).

Two lessons follow. Most lapse happens after the first gift, so first-time donors are your largest lapsed group. And frequency protects against lapse, which is why converting returning donors to monthly giving is one of the best reactivation outcomes.

Lapsed Donors vs. Lapsed Members

If you're a membership organization, keep lapsed members and lapsed donors apart. Dues buy membership benefits; donations are gifts. A member who didn't renew needs a renewal conversation, covered in our membership renewal letter guide. Someone who is both needs one coordinated message, not two competing ones.

Why Donors Stop Giving

You rarely learn the exact reason, but most fall into two groups: administrative lapse, where the donor didn't actually decide to stop, and relationship lapse, where something in their experience or circumstances changed.

Some of these are on you. If your data shows no thank-you and no update after the last gift, fix that in your donor stewardship plan before spending money on reactivation.

Prepare Your Data Before Reaching Out

A win-back campaign sent to bad data insults the people you most want back. Clean the list first.

Clean the List

1. Suppress deceased donors and check for recently deceased spouses in households.
2. Update addresses through a change-of-address service before any mailing, and remove hard-bounced emails.
3. Merge duplicates, so one person doesn't get three letters.
4. Honor do-not-contact, do-not-mail and unsubscribe flags.
5. Respect anonymity and recognition preferences.

Our guide to donor data hygiene covers these routines in detail.

Pull the Right Fields

For each lapsed donor, you need: first gift date, last gift date and amount, highest gift, number of gifts, giving channel, designation, how they first came to you (appeal, event, tribute, peer-to-peer) and whether they're also a member or volunteer.

Segment by History, Not Just Date

Base the ask on the last gift, not the highest. Asking a donor who stopped at $50 for $250 makes it easy to say no.

In campai, member and contact profiles support tags, filters and saved segments, along with notes and follow-up reminders, so each segment can be a saved list and each personal call a reminder on the right person.

A Win-Back Sequence

A single "we miss you" letter rarely does the job. A short sequence with a clear stop rule works better: anyone who gives drops out immediately and moves into your thank-you and welcome-back track.

Run lapsed monthly donors on their own faster track: an email within three days of a failed payment, a second email a week later and a phone call after two weeks.

Time the sequence so it ends before your main year-end giving appeal, or fold LYBUNTs into that appeal with their own letter version. For channel-specific advice, see our guides to direct mail fundraising and fundraising email templates.

Template 1: Impact Update Email (No Ask)

Subject: What happened since your last gift

Hi [Preferred name],

Last [month of last gift], you gave [amount] to help [Organization] [what the gift supported]. I wanted to show you what's happened since.

[Two or three concrete results, e.g., "We placed 214 dogs and cats in homes this year, opened a second foster training class and cut the waiting time for spay and neuter appointments from six weeks to two."]

[One photo or a 60-second story.]

Thank you for being part of that. No request today. I just wanted you to know.

[Name], [Title]

Template 2: "We Miss You" Letter With an Ask

Dear [Preferred name],

[For loyal donors: "You first supported [Organization] in [year], and you've stood with us for [number] years since."] [For first-time donors: "Last [month], you made your first gift to [Organization]."] Thank you. That support made a difference, and I'd like to show you how.

[One short story, 80 to 120 words, about an animal, person or family helped this year.]

We haven't heard from you this year, and I understand that lives and priorities change. If [cause] still matters to you, would you consider a gift of [last gift amount] to help [specific, near-term goal]? You can give at [short URL] or with the enclosed envelope.

And if you'd rather hear from us less often, or about something specific, just tell me. I read every reply.

With thanks, [Name], [Title]

P.S. [Optional: "Many supporters now give monthly. Even $10 a month covers [concrete result]."]

Template 3: Lapsed Monthly Donor Email

Subject: A quick note about your monthly gift

Hi [Preferred name],

Your monthly gift of [amount] to [Organization] didn't go through on [date]. This usually happens when a card expires or account details change.

If you'd like to continue, you can update your details here: [link]. It takes about a minute. If you meant to stop, that's completely fine, and thank you for the [number] months you gave. They added up to [total], which [concrete result].

Questions? Reply to this email or call me at [phone].

[Name], [Title]

Our guide to monthly giving programs covers how to reduce failed payments before they happen.

Template 4: Call Script for High-Value Lapsed Donors

"Hi [Preferred name], this is [Name] from [Organization]. Do you have two minutes? I'm calling because you've been such an important supporter, and I realized we haven't talked in a while.

I'm not calling to ask for anything today. I'd love to hear how you're doing, and whether we've kept you as informed as we should have.

[Listen. Ask: 'What made you first get involved?' and 'Is there anything we could do better?']

Thank you. Would it be all right if I sent you a short update on [program they supported]? And if you're ever interested, I'd be glad to show you around in person."

Record the answers in the donor's record the same day. If the donor mentions a reason for stopping, act on it before any ask.

Template 5: Preference Check Email

Subject: Should we stay in touch?

Hi [Preferred name],

You've supported [Organization] in the past, and we're grateful. We'd like to make sure we only send you what you actually want.

[Button] Keep me updated about [cause] [Button] Only send me the year-end update [Button] Please stop emailing me

Whatever you choose, thank you for what you've already made possible.

Reactivation Offers That Work Without Gimmicks

Lapsed donors need a reason to return. Discounts don't apply, but these do:

• A real match. If a board member or business has committed matching funds, say so, with accurate terms and deadlines. Only mention a match if it exists.
• A specific, near-term goal. "Help us fund 40 spay and neuter surgeries before winter" beats "support our work."
• Choice of designation. Let donors pick between two or three programs, especially those who stopped after a program changed.
• A small monthly option. For donors whose finances changed, $10 or $15 a month can be easier than a single larger gift.
• An invitation instead of an ask. An open house, volunteer day or behind-the-scenes tour brings back donors who first came through an event.
• A short survey. Asking for their opinion signals that their view matters and often reveals why they stopped.
• An anniversary. "It's been five years since your first gift" is a reason to reach out that feels personal rather than transactional.

Measure Reactivation

Measure every win-back campaign the same way so you can compare segments and years. To see the true effect, hold back a random 10% of each segment as a control group that gets no win-back messages. Some lapsed donors would have come back anyway, and the control group shows how many.

Here's a hypothetical example for the animal rescue's 640 LYBUNTs, with 64 held back as a control group and 576 contacted. Mailed letters went to 360 of them.

These numbers illustrate the method, not a benchmark. Your results will depend on your cause, your list and how long donors have been lapsed. Compare segments against each other, then shift effort toward the ones with the best lift per dollar.

The last row matters most. A reactivated donor who lapses again next year was a one-time rescue, not a win. Treat reactivated donors like new donors: a prompt, personal thank-you letter, an impact note after 90 days and a place in your regular stewardship calendar. Our guide to donor lifetime value shows how to put a dollar value on keeping them.

Know When to Stop

After a full sequence without response, move donors to a lower-frequency track, such as one year-end letter and one impact update a year. After several years without response, consider archiving them from appeals entirely. Always honor opt-outs immediately.

Prevent the Next Lapse

The cheapest reactivation is the one you never need. Three habits do most of the work:

1. An at-risk alert. Flag every donor ten months after their last gift and send an impact update with no ask.
2. A second-gift plan for new donors. Thank them within 48 hours, update them at 30 and 90 days, and make the second ask only after that.
3. Regular impact reporting. Donors who see results stay. A short donor impact report once or twice a year keeps them informed between asks.

In campai, the donations overview shows new and returning donors, top supporters and recent large gifts for any period, which makes a drop in returning donors visible before year-end.

Frequently Asked Questions

What is a lapsed donor?

A lapsed donor is someone who gave in the past but hasn't given within the period you define, usually the current or last fiscal year. Define the window in writing, such as "no gift in the last 12 months" or "no gift this fiscal year," and use it consistently in reports.

What do LYBUNT and SYBUNT mean?

LYBUNT stands for "last year but unfortunately not this year": donors who gave in the previous fiscal year but not yet in the current one. SYBUNT stands for "some year but unfortunately not this year": donors who gave in an earlier year but not last year or this year.

How long before a donor is considered lapsed?

Most organizations use 12 to 18 months without a gift, measured by fiscal year. Monthly donors are different: treat a stopped recurring gift as lapsed right away, because a quick, friendly payment update request often fixes it.

What should a lapsed donor letter say?

Thank the donor for their past support, show what has happened since their last gift with one concrete story, then make a specific ask, usually for their last gift amount. Offer a way to change how often they hear from you. Skip guilt and pressure.

Should you ask lapsed donors for the same amount as before?

Ask for the last gift amount, not their highest. If their giving was declining before they stopped, ask for a little less or offer a small monthly option. High-value lapsed donors should get a personal conversation instead of a printed ask amount.

Should you remove lapsed donors from your mailing list?

Not immediately. Move long-lapsed donors to a lower-frequency track, such as one year-end letter and one impact update a year, and archive them from appeals after several years without response. Remove anyone who asks to stop, and suppress deceased donors right away.

Next Steps

1. Write down your lapse definitions for LYBUNT, SYBUNT, dormant and lapsed monthly donors.
2. Pull your lapsed lists and count each stage, as in the table above.
3. Clean the data: deceased, addresses, duplicates and opt-outs.
4. Build three to five segments and adapt the templates for each.
5. Schedule the sequence so it ends before your year-end appeal, with a 10% control group.
6. Measure lift, cost and second-year retention, and add the ten-month at-risk alert to your stewardship plan.
