Most fundraising programmes pour the bulk of their energy into the top of the funnel, chasing new donors, and far less into keeping the ones they already have. The habit is understandable: acquisition is visible, it produces fresh names and immediate income, and it feels like growth. But a programme that only acquires is filling a bucket with a hole in the bottom. Every new donor you bring in this year is partly, and sometimes wholly, cancelled out by the donors who quietly slip away. The leaky bucket is the single most useful image in donor development: if you do not mend the holes, you have to pour faster and faster just to stay level.

This guide treats acquisition and retention as two halves of one job. It covers how to bring new supporters in through lead generation, how to understand who they are with donor personas, how to welcome them well, what actually keeps them giving, why they lapse, the crucial second gift, how to win back the ones who have drifted, and the handful of metrics that tell you whether any of it is working. It draws throughout on Hubbub's work with charities and on the wider evidence their team has gathered.

The leaky bucket: why retention matters as much as acquisition

Start with the arithmetic, because it is sobering. The national average donor retention rate sits at around 46 per cent, which means a typical organisation loses more than half of its donors every year. Put the other way round, the average attrition rate is 54 per cent. Acquire a thousand new donors while losing more than half of last year's cohort, and you are running hard to stand still.

The long-term cost of leakage is larger than it looks. Hubbub models two otherwise identical organisations over ten years, one losing 10 per cent of its donors a year and the other losing 25 per cent. That 15-point gap in churn is not a rounding error. Where both bring in new donors and grow their gifts, the lower-churn organisation ends up generating around 81 per cent more in revenue and retaining 997 more donors, roughly 130 per cent more, than its leakier twin. The two started in the same place. The only difference was how well they held on to people.

Retention compounds quietly in a way acquisition never does. A retained donor costs almost nothing to keep relative to the cost of finding a new one, gives again, often gives more, and becomes a candidate for regular giving, a larger gift, or a legacy. Remember too that roughly 80 per cent of fundraising income tends to come from around 20 per cent of donors. Those major supporters did not arrive as major donors. They began as ordinary first-time givers who were retained, stewarded and developed over time. Lose them early and you never find out who they might have become.

None of this is an argument against acquisition. You will always need new donors to replace natural losses and to grow. It is an argument for treating retention as the foundation that acquisition is built on, rather than an afterthought.

Acquisition channels and lead generation

Acquisition works best as a funnel rather than a single ask. People move from awareness, through interest and engagement, to a first gift, and lead generation is the work of guiding them along that path rather than demanding a donation from a complete stranger. The most effective programmes plan the whole funnel at once, including what happens after someone gives, instead of treating the first gift as the finish line.

Several channels feed the top of that funnel. Your website is the hub: every piece of content you produce should live there, supported by search engine optimisation so people can find you, and by retargeting so the ones who visited but did not act see you again. Social media widens the reach, and the format should follow the audience, with visual content suited to platforms like Instagram and TikTok, and written content working well over email and on Facebook with older supporters. Events, peer-to-peer campaigns and in-person moments bring in donors who would rarely surface through a cold appeal; a format such as our Challenge Week guide shows how an event can deliver large numbers of brand-new supporters in a single week.

Two disciplines make lead generation pay. The first is a content strategy that serves two audiences at once, the prospects you are trying to attract and the supporters you already have, so the same effort does double duty. The second is lead scoring: rather than chasing volume, you rank prospects by how engaged and how likely to give they are, and concentrate your limited time on the warmest. Quality of leads matters more than quantity, because a thousand names who never give are a cost, not an asset.

Above all, the way you acquire shapes how well you retain. Tactics built only to maximise immediate cash and headline donor numbers, with little regard for genuine engagement or the start of a relationship, reliably produce higher churn later. You end up on a treadmill, endlessly replacing the donors your own acquisition methods taught to leave. Acquiring fewer donors who care about your cause beats acquiring many who do not.

Donor personas: understanding your audience

You cannot tailor what you do not understand, and donor personas are how good programmes turn a faceless database into a handful of people they can picture. A persona is a fictionalised but data-grounded profile of a type of supporter, built from your actual donors rather than from assumptions. It pulls demographics, behaviour and preferences into a recognisable character your whole team can hold in mind when they write an appeal, plan an event or design a web page.

The payoff is measurable rather than merely tidy. Organisations that use personas report shorter average times between a constituent's first interaction and their first donation, and shorter times between a first gift and a second. Personas improve both acquisition and retention, the two outcomes this guide is built around.

Building them is methodical. Start by segmenting your data into meaningful groups, by age, by giving status, by graduation year, by whatever divisions actually matter for your cause. For each group, gather what you can on how they tend to give, whether online, by phone or by post, on the campaigns or triggers that first prompted them to donate, on their demographics, on how they prefer to be contacted, and on what motivates them. Draw on more than one source: your donor database, your website analytics for online givers, and, importantly, direct conversations with engaged donors who will tell you things no spreadsheet can. Then write each persona up as a short profile with a name, a stock photo, a brief biography, their goals and motivations, and their contact preferences, kept deliberately concise and led by the data.

Once they exist, personas only earn their keep if they are used. Share them across the whole organisation and apply them everywhere: the wording of your asks, the shape of your events, your stewardship plans, your communications and even your website design. The point is to stop sending one message to everyone and start speaking to each segment in the terms that move it.

The welcome and onboarding experience

The riskiest moment in a donor's life with you is the gap between their first gift and their second, and the welcome experience is what carries them across it. A new donor has taken a leap of faith. What you do in the next few days tells them whether that faith was well placed, so a warm, prompt, well-judged welcome is one of the highest-return things a fundraising team can do.

The first act is the thank-you, and timing matters more than polish. Acknowledge a gift quickly, ideally within 24 to 72 hours, while the donor still feels the warmth of having given. Make it personal: a genuine signature, the name and contact details of a real person, and language that sounds like a human being rather than a receipt. A simple call or voicemail can be more powerful still. As fundraising researcher Penelope Burk has found, "donors who receive a call or voicemail are significantly more likely to make that all-important second gift and to increase their gift amount." Few welcome tactics are cheaper or more effective than picking up the phone.

Beyond the thank-you, a good onboarding sequence orients the new supporter. A welcome pack or series can explain what their support makes possible, set out the benefits and opportunities of being involved, point to ways to engage beyond giving such as volunteering, and begin to show impact rather than immediately asking again. Balance is the thing: mix solicitation with genuinely informative content like newsletters and stories, so the relationship does not start and end with a hand held out. Our welcome journey template lays out a sequence you can adapt, and the wider craft of moving people through these early stages is covered in our guide to donor stewardship.

What drives retention

Retention is not a single tactic but a posture, and the sector has a name for it: relationship fundraising. Ken Burnett, who coined the term, defines it as an approach centred "not around raising money but on developing to its full potential the unique and special relationship between a charity and its supporter." The income follows from the relationship, not the other way around. Programmes that internalise this keep their donors; programmes that treat each donor as a wallet to be reopened do not.

In practice, several behaviours drive the relationship forward. Acknowledge gifts promptly and personally, every time, not just the first. Engage donors before and after a gift rather than only at the point of asking, through tours, events, updates and stories, so you build a connection that does not depend on a transaction. Above all, banish the feeling every lapsed donor describes in some form: "I only hear from you when you want money." If the only contact a supporter has from you is an ask, you have taught them to associate your name with being taken from rather than being part of something.

It helps to understand what people are actually seeking when they give, because it is rarely the transaction. The fundraising thinker Simone Joyaux identifies seven things donors want from their involvement: to be heard, to tell their stories, to realise their dreams, to join a fight, to join a tribe, to feel flattered, and, simply, to matter. A retention strategy worth the name is really a programme for delivering those feelings, consistently, over years.

Donor churn: why supporters lapse

Churn is the measure of the leak. Hubbub defines it plainly as the percentage of donors who do not give again within twelve months, calculated as the donors lost over a twelve-month period divided by the total donors in that period. A 25 per cent churn rate means a quarter of your donors quietly fail to return each year, and as the ten-year comparison above showed, small differences in that rate compound into enormous differences in donors and revenue.

Supporters lapse for reasons that are mostly within your control. Some are acquired through tactics that were never built for retention, drawn in by a one-off prompt with no relationship behind it, so their departure was effectively decided at the point of acquisition. Many lapse because they felt unthanked, unheard, or contacted only when money was wanted, the precise failures that good retention practice exists to prevent. Others drift simply because nobody noticed they had gone quiet and nobody reached out. A smaller number leave for reasons you genuinely cannot touch, a change in their circumstances or their priorities, but these are the minority. The uncomfortable truth in most churn analysis is that the majority of lapsing is a response to how the donor was treated, which is also the good news, because it means churn is something you can act on rather than merely suffer.

The first step is to see it. Analyse the patterns in your database, segment your lapsing donors, and look for the moments where people tend to fall away, very often the gap after the first gift. Free sector tools such as the AFP's Fundraising Fitness Test and Growth-in-Giving Report help you benchmark, and a donor churn calculator lets you model how a given rate plays out for your own programme over time. You cannot fix a leak you have not located.

The crucial second gift

If one number decides a programme's future, it is the proportion of first-time donors who give a second time. First-gift retention is notoriously the weakest point in almost every programme, and it is also the highest-leverage one, because a donor who gives twice is dramatically more likely to keep giving than one who has given only once. The second gift is the moment a one-off response hardens into a habit.

Almost everything in the earlier sections converges here. The prompt, personal thank-you; the welcome sequence that shows impact before it asks again; the phone call that Penelope Burk's research links directly to second gifts and larger ones: all of it is, in the end, in service of converting that first gift into a second. This is why the welcome experience deserves disproportionate attention and resource. A modest improvement in your first-to-second gift conversion rate ripples through every retention and lifetime-value figure you track for years afterwards, because each donor who clears that hurdle is far more likely to clear all the ones that follow.

The practical implication is to design your programme around the second gift deliberately rather than hoping it happens. Map the journey from first gift onward, decide what you will send and when, make at least one piece of that early contact a genuine thank-you with no ask attached, and treat a second gift not as a happy accident but as the explicit goal of the first ninety days. Our work on building a regular giving programme goes further, because converting a strong first or second gift into a committed monthly relationship is the surest way to lock in long-term retention.

Reactivating lapsed donors

Not every departing donor is gone for good. A supporter who gave to you once chose you for a reason, and that reason often still exists, which makes lapsed donors a warmer prospect than cold strangers and reactivation a more efficient use of effort than pure acquisition. The key is to treat win-back as a deliberate programme rather than an occasional guilty afterthought.

Begin by defining what lapsed means for your programme and segmenting accordingly, because a donor who has missed one year needs a different approach from one who last gave five years ago. For the more recently lapsed, a well-judged win-back message that acknowledges the absence without scolding, reminds them of the impact they helped create, and makes it easy to return, can recover a meaningful share. Lead with what their past support achieved and what is possible now, not with the fact that they stopped. Where you can, tailor the approach by persona, since a reason that re-engages one segment will fall flat with another. Our win-back email template gives you a tested starting point to adapt.

Be realistic about the limits. Reactivation will not recover everyone, and the effort is best concentrated on the segments most likely to respond and most valuable if they do. But a structured win-back programme, run consistently, plugs one of the larger holes in the bucket, and it nearly always costs less than acquiring an equivalent number of brand-new donors.

The metrics that matter

You cannot manage what you do not measure, and donor development rewards a small set of metrics watched closely far more than a large dashboard glanced at occasionally. Three matter most.

Retention rate is the share of last year's donors who gave again this year, the direct inverse of attrition. Against a sector average near 46 per cent, even modest improvements are valuable, and the long-run prize is large: Hubbub's modelling shows that lifting retention from 46 per cent to 90 per cent turns a ten-year loss of 786 donors into a net gain of 1,552. Track it overall and, more usefully, by segment and by cohort, paying particular attention to first-gift retention, which is where most programmes leak hardest.

Donor churn is the same picture from the other side, the percentage of donors who do not return within twelve months. Calculate it as lost donors over a period divided by total donors in that period, model how your current rate compounds over five and ten years, and use that projection to make the case internally for investing in retention rather than only in acquisition.

Lifetime value captures the total worth of a donor over the whole of their relationship with you, not just their first gift. It is the metric that justifies spending on welcome and stewardship, because it reveals that a retained donor is worth a multiple of an acquired one, and it reframes the cost of a thank-you call or a welcome series as an investment with a clear return. Alongside these three, watch time-to-conversion, how long it takes a new contact to make a first gift and then a second, since shortening those gaps, exactly what good personas and onboarding do, lifts every other number on the list.

The discipline that ties it all together is reviewing regularly, with quarterly a sensible rhythm, and giving each strategy enough time to prove itself, with serious assessment points at around six and twelve months. Donor development is a long game, and the programmes that win it are the ones that measure patiently, mend the leaks they find, and keep the bucket full year after year.

Frequently asked questions

Is it really cheaper to retain a donor than to acquire one? Yes, and usually by a wide margin. Acquiring a new donor carries real cost in advertising, content, events and staff time, whereas keeping an existing one largely costs the price of good stewardship. Retained donors also give again, often give more, and can develop into major or regular givers, so the return on retention compounds in a way acquisition spending does not.

What is a good donor retention rate? The national average is around 46 per cent, so anything meaningfully above that is doing well, but the more useful target is to beat your own previous year and to improve first-gift retention specifically. Small, steady gains compound powerfully: Hubbub's modelling shows the difference between high and low retention runs to hundreds of donors and substantial revenue across a decade.

Why is the second gift singled out as so important? Because first-gift retention is the weakest point in almost every programme, and a donor who gives a second time is far more likely to keep giving than one who has given only once. Converting first-time donors into second-time donors is the highest-leverage improvement most programmes can make.

Do small charities really need donor personas? They benefit as much as large ones, often more, because their resources are tighter and personas help them aim limited effort where it counts. Personas are built from your own donor data, conversations and analytics, so you do not need a big budget, only a willingness to look at who your supporters actually are.

How quickly should we thank a new donor? Promptly, ideally within 24 to 72 hours, while the gift still feels fresh to them. Make the thank-you personal, with a real signature and a real contact, and where you can, add a call or voicemail, which research links directly to more second gifts and larger ones.

Where should we start if our retention is poor? Start by measuring, so you know your retention rate, your churn and where in the journey people lapse, then fix the welcome experience and the second gift first, since that is where most programmes leak hardest and where improvement pays back fastest.
