Conversion Is Not Acquisition: How a Strong Fundraising Year Can Hide a Broken Funnel

Sep 15

Earlier this month, CDP published two sets of numbers nine days apart. The first is a full-year study of the more than 319,000 new donors who came to 51 public media stations in 2025. The second is the August index, covering a narrower window: this past May through July, measured against the same three months a year earlier.

Both are careful pieces of reporting. Read against each other they reveal something more specific than a strong year followed by a correction, and what they describe should change which number stations look at when the fall drive closes.

Almost none of last year's donor growth came from anything a station actually built. The new donors were younger and more digital than any group before them, and most of the traffic that produced them was organic, driven by the spotlight on the funding fight.
New donor counts for May through July are down more than 40% against the same months last year. Radio organizations are down furthest. Nothing inside the stations changed. The news stopped doing the work.
The donors who arrived last year are holding up this year's numbers. Membership revenue is close to flat and sustainers are up, which is exactly why none of this will register as a problem.

The best acquisition year in public media's history was not, in any meaningful sense, acquisition. And neither report says what that means for the year ahead.

The donors public media has spent a decade chasing showed up last year

The good news here is real. The 2025 group is the one nearly every membership operation has been trying to reach.

The age problem that appears in every station strategic plan moved in the right direction for the first time in years. Millennials nearly doubled their share of new donors, and donors under 45 arrived at close to twice their historical rate.
More than six in ten of the youngest new donors came in as sustainers rather than one-time givers, which is the conversion step that normally takes several touches and a year of stewardship to produce.
For donors under 60, roughly nine in ten first gifts happened online. For Millennials, direct mail accounted for three percent of first gifts. Whatever the rest of the program looks like, the part of the file that grew last year is a digital file.

The spotlight did the acquiring, and the field's own data says so

There is a line in the full-year analysis most readers will skim past. Much of the online traffic, it notes, was organic, driven by the spotlight on public media's funding fight. It then asks, without answering, what role digital advertising and social should play from here.

That is the field's own data authority reporting that the acquisition happened outside the building. It is worth being precise about what does and does not follow from it.

The conversion was earned. Stations moved a flood of first-time visitors onto monthly forms and through them, which is real work, and the sustainer share suggests many stations did it better than they get credit for.
The arrival was not earned, and nothing should be planned as though it was. No media buy produced that traffic. No newsletter growth program or search investment did either. A Senate vote did.
A handful of stations went out and built against the same moment instead of waiting to see who showed up. Those are the ones that can say today what their spend actually produced, which is the difference between a program and a windfall.

Now that the spotlight is off, the new donors have stopped arriving

The August numbers make the point better than any argument could. Comparing this past May through July against the same three months in 2025:

New donor counts are down more than 40%, with declines at or near that level in every organization size. This is not a big-market story or a small-market story.
Radio organizations saw the steepest drop by a wide margin. The stations with the least diversified revenue took the hardest hit.
The only variable that moved was whether anything outside the building was generating demand. Same staff, same donation forms, same email calendar, same drives, in many cases the same creative.

The fall drive will look fine, because revenue is the last number to move

Most stations are in a drive this week, and most of those drives will close in reasonable shape. Membership revenue is close to flat against a benchmark that was extraordinary by any standard, sustainers are up, and across twelve months the revenue picture looks strong.

All of that is last year's donors doing exactly what they were supposed to do. They are still here, still giving monthly, holding up the revenue line while the number underneath them falls.

That is what makes this dangerous rather than merely disappointing. Sustainer revenue is the most lagging indicator) in membership fundraising. A donor acquired in July 2025 keeps paying through 2026 and into 2027 whether or not anyone acquires a replacement.

By the time the number is visible, the decision that would have fixed it is several budgets back. The revenue report that finally shows acquisition broke will be describing a year that closed well before it.
Fall drive debriefs are built around revenue against goal, and revenue against goal is going to look defensible this year. The season gets filed as healthy, and the file rather than the drive is the reason.

Nonprofit fundraising ran this experiment in 2020, and lost

Public media is roughly a year into a cycle the wider nonprofit world finished five years ago.

In 2020 a crisis produced a surge of first-time donors across nonprofit fundraising. Giving rose, donor counts rose, acquisition rose sharply, and organizations of every size found themselves holding files full of people they had never gone out and found.

Year two is where a surge is decided, not year one. New donor retention came in below 20%, meaning more than four in five of those first-time donors never gave a second gift.
Donor counts have declined in nearly every year since, and the most recent national figures, published this spring, show first-year conversion still unsolved. Five years on, nobody has cracked it.
Most organizations stewarded those donors about as well as they stewarded anyone else. Stewardship was not the failure. A file built by an outside event does not replenish itself.

What to pull when the drive closes

Five things, none of which require a new hire.

Pull new donor counts against last year and against 2023, and put both next to the revenue figure in the board report. A season where revenue held and new donors fell 40% is a season where the file performed and the drive did not. The revenue number will not tell anyone that, and it is the only number most debriefs contain.
Steward last year's donors in the channel they arrived in. They came in online and they give online. Folding them into the general file and the legacy mail calendar is a live test of whether a direct mail program can hold a digitally acquired donor, and the result is effectively settled by the end of 2027.
Build the case for an acquisition line now, out of this fall's debrief. Drive promotion and audience acquisition come out of the same budget conversation and are not the same activity, and only one of them works when nothing outside the building is generating attention. FY28 planning starts in the spring, and the argument that wins then is the one documented while the season is still fresh. At a striking number of major market stations there is no marketing function at all, which leaves acquisition unowned by default rather than by decision.
None of that works without knowing which source produced which donor. A station without that answer can fund campaigns but cannot fund acquisition, because there is nothing to evaluate at the end of it. Source definitions get written once, before the spend, or they get argued about afterward.
Audit every path into the giving form before Giving Tuesday. Forms, links, buttons, the mobile flow, the places where a gift starts and quietly does not finish. It costs nothing, it is the only item here that can be finished this quarter, and it is the one most likely to pay for itself before December.

The bill for last year's acquisition arrives in FY28

High-dollar giving is already softening, and retaining those donors is being named across the community as the priority for the year ahead. Sustainer revenue will hold a while longer. Both of those are statements about the 2025 file, and neither one is a statement about what comes after it.

Last year's donors have already been through one year-end, in December 2025, weeks or months after they arrived and while the story was still everywhere. This December is the second, and the first one where nothing outside the building is helping. December 2027 falls inside a fiscal year whose budget will already have been written.

The last real moment to fund a response is spring planning, and the case made then will only be as good as the numbers pulled this fall.

Last year the news did the acquiring. That was the anomaly, not the new baseline. The question worth putting in the debrief is not how the drive went. It is who is doing the acquiring now.
