$55 a month from her phone. The receipt goes out on its own.
Raise money, keep supporters engaged, and see what to do next.

$55 a month from her phone. The receipt goes out on its own.

Sarah is new and nobody has been in touch since her first gift. Cotara shows why she needs attention.

She gets the task, the words and a due date.

She edits the thank-you and sends it from her own email.

It links each follow-up to what happened next, so you can see which ones bring people back.
A gift gets recorded.
The next step shouldn’t depend on someone remembering.
Plenty of donor information. More work deciding what to do with it.
Know who needs attention, why, and what to do next.
Sarah is one of your steadiest supporters.
Keeping supporters engaged is the harder part. Cotara is being built to help small fundraising teams know who needs attention and make the follow-up happen.

Four in five first-time donors from 2024 didn’t give again in 2025. Start with the number you can measure.

PlanningA one-question survey beats guessing. But the people who answer are rarely the people you most need to hear from.
Two monthly donors miss a payment in the same week. On your report they can look the same. They may need very different things.
Two monthly donors miss their gift in March.
The first, Mark, has given $25 a month for fourteen months. His card expired in February and the bank issued a new one. He doesn’t know his gift failed.
The second, Anne, has given $40 a month for three years. Her card is fine. She cancelled it with her bank on purpose, because something about your last email didn’t sit right with her.
On your payment report, Mark and Anne can look very similar. Both gifts are missing. Both people may get the same automatic email. And that email is wrong for at least one of them.
Most failed monthly gifts happen for ordinary reasons. The card expired. The bank blocked a charge it didn’t recognize. The donor got a new card after a fraud alert. Some payment processors update expired cards automatically when the bank shares new details, but that doesn’t catch every case.
None of these is a choice to stop giving. Mark needs a service, not a conversation. A short, friendly note from a real person with a link to update his card is enough.
Anne is different. She chose to stop. If she gets a cheerful “your card needs updating” message, it tells her nobody is paying attention. That can turn a quiet exit into a bad one.
A failed payment tells us that money didn’t arrive. Sometimes the reason is technical. Sometimes a supporter has intentionally stopped giving. The payment record may give us clues, but it doesn’t necessarily tell us what the person intended. That’s where the next conversation matters.
Banks often share very little about why they refused a charge. Meanwhile the person who knows Anne, and might have noticed the email that upset her, never hears that her gift stopped.
I can’t tell you how many failed gifts in a typical organization are card problems and how many are quiet cancellations. I haven’t seen good public data on it, and I suspect it varies a lot. That’s exactly why it’s worth checking your own. Pull the last 90 days of failed gifts, read what the records say, ask a few of the people involved, and see what you find.
Mark and Anne both stopped giving in March. Only one of them meant to.

Book a DemoTunde gave $60 to the spring appeal. He got a receipt within a minute. Then nothing.
Six months later the autumn appeal arrived in his inbox. It was the first time the charity had written to him since the receipt. It asked him for money.
Tunde did not give again. He did not decide against it. He just felt like a stranger being asked for a favour.
Most teams treat a first gift as the end of a campaign. The money is counted, the receipt goes out, and the team moves on to the next appeal.
For the donor, the first gift is the start. They took a small risk. They want to know what happened to it, and whether anyone noticed.
The gap between the first gift and the next message is where donors drift away.
The next ask comes after the donor has heard from you at least three times.
Look at the people who gave for the first time last year. How many gave again? That is your baseline. Write it down. Then choose the next five first-time donors and give each of them the plan above. In three months, compare.
Cotara spots first-time donors who have not given again. It drafts a short welcome series for you: emails and a call script. You edit the words and send them from your own email, on your own schedule.
Any gift from the same person after their first one, in any campaign. Count it over a fixed window, for example twelve months, so you can compare year to year.
No. A two-minute thank-you call to a new donor is one of the best uses of staff time. Start with the ten most recent donors and see how it feels.
After the donor has heard from you at least three times without an ask. The exact gap depends on your calendar. The rule is to give before you ask.

EventsMany of your guests may be people you have never met. Do not lose them.
ReportsOne page, five parts, and a date you set on day one.
We know who bought the tables and what the night raised. We rarely know who came because someone they trusted asked them.
Something interesting happens at fundraising events, and most of us don’t record it.
A community food bank holds a gala for 180 people. The team knows about 120 of them. The other sixty came as guests of table hosts. One of those hosts, a long-time volunteer named Carol, filled her table with neighbors who had never heard of the food bank.
The next morning, everyone who bought a ticket gets a thank-you. The sixty guests get nothing. Their names are on a paper sign-in sheet. And nowhere in the database does it say that six of them came because Carol asked.
The guest list tells you who attended. It doesn’t tell you why. Carol may have been the reason those neighbors first walked through the door. What happened afterward could tell us whether that introduction developed into a relationship with the organization.
When we lose that link, two things go wrong. We follow up with the guests as if they were strangers, and we never thank Carol for the thing she actually did, which was to vouch for us.
There’s evidence that how we invite supporters to bring others in matters. In a field experiment with 77,485 donors, published in Marketing Science in 2023, Ike Silver and Deborah Small tested two versions of a request to share a donation. The standard version asked people to share. The other told donors their gift could start a chain reaction.
The chain-reaction version increased click-through by 5.1% and the likelihood of recruiting at least one later donation through word of mouth by 12.4%. That’s one experiment, online, with one organization’s donors, so I wouldn’t treat it as a rule. But it supports something I believe: the person who brings someone else is doing real work for your cause, and the way we ask shapes whether they do it.
Six months later, you’ll be able to ask a question most organizations can’t: which of our supporters bring others in, and what happens to the people they bring?

Book a DemoRuth is the executive director of a youth centre. Her Spring Appeal report was due on November 24.
She wrote it on November 23, after the children had gone home. It was fourteen pages. It had every number she could find.
At the board meeting, the chair turned to page one and asked a single question: "Did we do what we said we would do?" The answer was somewhere on page nine.
Most reports are written from memory at the deadline. They list what the team did, not what the team promised. Nobody checks whether the report arrived on time. And the board reads the first page, so the first page decides everything.
Everything else goes into an appendix, for the people who want it.
When you launch a campaign, choose the report date and tell your donors. Now the report is a promise, and a promise gets done. Keep a simple count: how many campaigns did we report on time? A board likes a number like "4 of 4".
Keep a running note during the campaign. Two lines a week: what happened and what you decided. When the deadline arrives, most of the report is already written.
Take your last report. Cut it to one page using the five parts. Show it to one board member and ask what they would still want to know.
Cotara tracks every campaign against its report date and shows how many you sent on time. When a report is due, it drafts one from your results. You review it, edit it and send it.
One page for the main report, with an appendix for details. If the board cannot find the answer to "did we do what we said?" in thirty seconds, shorten it.
Give donors a shorter, warmer version of the same facts: what you promised, what you raised and what you did with it. Send it by the date you promised.
Say so on page one. Explain what you learned and what you will change. Boards trust honest reports more than perfect ones.

Donor retentionA receipt is not a welcome. A simple 30-day plan for first-time donors.
EventsMany of your guests may be people you have never met. Do not lose them.
A family gave every week until June. After August they gave nothing. By then they had also stopped coming on Sundays.
The church treasurer saw it in November, while preparing year-end tax receipts. She mentioned it to nobody. It was not her role, and it felt private.
In February the pastor learned that the father had lost his job in the summer. The family had needed help for six months.
The first sign of trouble was in the giving record. It was read as a finance report, by the one person who does not do pastoral care. The people who care for others never saw it.
This is not a case for pastors to watch what people give. Many churches rightly keep amounts private. It is a case for a small, careful step between the finance office and the care team.
Put it in plain words in your member guide. "We look for changes so we can care for you. We never discuss what you give." Members who know the rule trust it.
Ask your treasurer and your care lead to meet for fifteen minutes. Agree who receives a "pattern changed" note, how often, and what the first response will be. Write it on one page.
Cotara shows which supporters' giving has changed and suggests a short, caring note or call. You choose who sees what. Your team sends the message and records what happened.
It can be, if members know about it, the finance office keeps amounts private, and the only purpose is care. Check with your leadership and, where needed, your denomination or legal adviser.
That is the most common outcome. A kind check-in costs little and is rarely unwelcome. Never mention giving in the conversation.
One trusted person on the care team, not a committee. Fewer people means more privacy and a faster response.

A one-question survey beats guessing. But the people who answer are rarely the people you most need to hear from.
A community center was planning its 2027 campaigns. The board chose three priorities in one meeting, from experience and instinct. One member was sure parents cared most about the Saturday STEM club. Another thought it was the meal program. Nobody asked a parent.
So the next year, they did. They sent one short question to their email list: “What should we focus on in 2027?” Ninety people answered. The STEM club won easily.
Then someone looked at who had answered.
Most of the ninety were long-time donors and volunteers. Very few were families who used the meal program, because most of those families weren’t on the email list. Some didn’t read English comfortably. Some had never been asked anything by the center before.
The survey told them what the respondents thought. The mistake was assuming the respondents spoke for the whole community. It reached the people who were already closest to the organization, and their view was treated as everyone’s.
Tell everyone what you decided and why, including the people whose favorite didn’t win. “Donors told us STEM club. Families at the meal program told us meals. Here’s how we’re funding both.” People who see their answer used are more likely to answer next time.
The board may still choose the same priorities. The difference is that now they’ll know whose priorities they are.
This community center is a composite example. Names and details are illustrative.

Half a million new donors took part. Thank-you calls didn’t change whether they gave again, though experts predicted they would.
Picture a fundraising team that makes 200 thank-you calls in a month. Every call gets made. The task list turns green. At the next meeting, everyone agrees it was a good month.
Now ask a different question. Not how many calls were completed, but what changed because they were made.
We measure whether the call happened. But how often do we measure whether it changed anything?
In 2023, the economist Anya Samek and Chuck Longfield, formerly chief scientist at Blackbaud, published a field experiment in the American Economic Journal: Applied Economics. They worked with 70 public television stations and a large national nonprofit. More than half a million first-time donors took part. Some were assigned at random to receive a thank-you call that described the impact of their gift and asked for nothing. The others got no call.
They followed those donors for at least a year, and in some cases five. The calls made no measurable difference to whether people gave again, and no difference to how much they gave when they did.
Before the results came in, the researchers asked fundraising professionals what they expected. The experts predicted the calls would raise retention by 80%.
The gap between what we believe works and what we can show works is bigger than most of us admit.
It doesn’t mean thanking people is pointless. Gratitude has value of its own, and a call can do things a retention number won’t capture. It also doesn’t mean every kind of contact fails. This was one kind of call, for first-time donors, in two settings.
Timing matters too. According to the authors, most calls were made by paid callers three to seven months after the first gift. So the study doesn’t tell us whether a personal call within a day or two of the gift would have the same result. That’s an open question, and an important one.
What it does mean is that “we followed up” isn’t the same as “we made a difference.” Those are two different claims, and most of our reporting only checks the first one.
Most fundraising advice is about doing more: more calls, more stories, more touches. I think the more useful question is narrower.
Which follow-up, for which supporter, under what circumstances, actually changes what happens next?
A new donor who gave once after a gala might need something different from a neighbor who has given every December for six years. A thank-you that works for one may be noise to the other. We rarely test this. We repeat what feels right.
Samek has suggested a simple approach: hold the calls back from a random 10% of donors and compare how often each group gives again. You don’t need a research budget for that. You need a list, a coin flip and patience.
Be honest about the limits. A small nonprofit may simply have too few donors to detect a real difference, and one test won’t settle anything. It will still teach you more than assuming.
So here’s the question I’d put to any team, including mine. If you complete every follow-up task this month, how will you know whether any of them made a difference?
Book a 30-minute demo and we will show you with your own donor file.
Book a DemoDollars are up and donors are down. For a small nonprofit, the number that matters most is one most teams never calculate.
Imagine your nonprofit had 400 donors last year. If your retention matched the sector benchmark of 43.3%, about 173 of them would give again this year. That leaves 227 people to replace just to keep the same number of donors.
Now ask yourself a harder question. How much of your team’s time goes into finding new donors, and how much into understanding why existing ones don’t come back?
That 400-donor organization is an illustration, not a forecast. Your own numbers will be different. But the arithmetic is the reason I think retention deserves more attention than it gets.
The Fundraising Effectiveness Project tracks giving across 15,102 organizations and 7.8 million donors. Its Q4 2025 report found that charitable dollars rose 5.0%, the strongest growth in five years. The number of donors fell 3.6%, the fifth straight annual decline. Overall donor retention moved from 43.1% to 43.3%.
Most of the growth came from major and very large donors, while participation from small donors kept falling. More money is coming from fewer people. A large charity can absorb that. A small one usually can’t.
The overall figure hides two very different groups. According to the FEP figures for 2025, as cited by Bloomerang, 18.9% of new donors from 2024 gave again in 2025. Donors with an established giving history returned at 59.3%.
That’s the 18.9% problem. Four in five first-time donors from 2024 did not give again in 2025, and first-time retention was essentially flat compared with the year before.
One detail matters here. This is retention across calendar years. It isn’t the share of donors who ever make a second gift. Someone who first gave in January 2024 could have given again that same year and still not appear as retained in 2025.
It’s tempting to read the gap between 18.9% and 59.3% as proof that a second gift turns someone into a loyal donor. I don’t think the data supports that. The 59.3% describes people who already had a giving history. It doesn’t tell us what caused their loyalty.
The same caution applies to FEP data showing that donors with more past gifts return more often. Through the third quarter of 2024, people with one gift returned at 18.6%, two gifts at 38.1%, and three to six gifts at 61.2%. That’s a pattern across donors, not proof that any single action moves someone up the ladder. People who were already more committed may simply give more often.
A number can tell you where to look. It can’t tell you what to do.
You can work out your own figures with the free donor retention calculator.
The sector’s numbers will move slowly. The more useful thing is to know your own, and to be honest about what you do and don’t yet know about why they move.

Benchmarks: Fundraising Effectiveness Project, Q4 2025 report (overall retention 43.3%; first-time donor retention 18.9%, as cited by Bloomerang). Your own trend matters more than the average.
Take everyone who gave last year. Count how many of them gave again this year. Divide the second number by the first and multiply by 100. That’s your donor retention rate.
Do the same for first-time donors on their own. It’s usually the lower number, and the one that moves fastest when someone owns the follow-up.

The idea behind it hasn’t changed. Most nonprofits already have the data. What they don’t have is time to work out who needs them this week, who should reach out, and whether any of it made a difference. Cotara 2.0 is built to close that gap.
The new look is live today. The three features below are rolling out now in early access.
Every week, Cotara reads the data you already have, from gifts and events to email, and shows a short list of supporters who need attention. Each name comes with the reason in plain words, like a first gift nobody has followed up yet or a monthly card that failed. No scores to decode and no dashboards to interpret.

Each item on the list can become a task with an owner, a due date and the words already drafted. The person who owns it reads the draft, changes it and sends it from their own email. Personal messages always go through a person. Routine messages, like receipts, still go out on their own.

Cotara links each follow-up to what happened next: a reply, a second gift, or nothing at all. Over time you can see which follow-ups bring people back, and track the number that matters most for small teams, the share of new donors who give a second time.
Outcomes show what happened. They don’t prove what caused it. If you want to know whether a follow-up actually works, hold it back from a small random group first. Our free holdout test builder does the split for you.

The fastest way to understand Cotara 2.0 is to see it on your own donors. Book a 30-minute demo and we’ll walk through your first weekly list together. If you’d rather start on your own, try our free tools. No sign-up needed.
Book a 30-minute demo and we will show you with your own donor file.
Book a DemoUpload a gift export and see what share of new donors made a second gift within 90, 180 and 365 days, and how long it usually took. The measure that matters most for small teams.
How it works: a donor’s first gift in the file starts their clock. Each window only counts donors whose first gift is at least that many days before the last gift in your file, so recent donors don’t pull the numbers down unfairly. Gifts on the same day count as one. This is different from calendar-year retention: someone who gave twice in one year counts here even if they didn’t give the next year. Read why it matters in the 18.9% problem.

Find out whether a follow-up actually works. Paste or upload your donor list, and we split it at random into a group that gets the follow-up and a group that doesn’t.
How to use it: send the follow-up only to the test group. Six to twelve months later, compare how many people in each group gave again. If your list is small, the detectable difference above will be large. That’s worth knowing before you start. Why this matters: in a study of 500,000 new donors, thank-you calls made months after the gift didn’t change repeat giving (read the article).

See what a few points of donor retention are worth over three years, in donors and in dollars. A simple projection to support a decision, not a forecast.
| Year | Donors at current rate | Donors at target rate | Revenue difference |
|---|
How it works: each year, donors = last year’s donors × retention + new donors. Revenue = donors × average gift. It assumes gift size and new donor numbers stay the same, which they rarely do. Use it to compare scenarios, not to predict your budget. Sector benchmark: overall retention was 43.3% in 2025 (Fundraising Effectiveness Project).
