Beyond the Monthly Gift: Seven Lessons For Growing Sustainer Value

What Epiphany Benchmarking reveals about donor retention, recurring giving, and building stronger relationships with sustaining donors.

For years, nonprofit fundraisers have understood the value of sustaining donors. Predictable revenue, stronger retention, and deeper donor relationships make recurring giving one of the most important components of a healthy fundraising program. But as sustainer programs mature, the conversation is changing. The question is no longer simply how to acquire more monthly donors. It’s increasingly about building stronger, more valuable relationships with sustaining donors while continuing to grow the program.

That shift was at the center of the October 2026 Epiphany Benchmarking Sustainer Giving meeting, where nonprofit fundraising leaders explored acquisition strategies, donor retention, payment methods, upgrades, and opportunities to increase long-term donor value.

Epiphany Benchmarking, co-developed by ROI Solutions and Contributor Development Partnership (CDP), brings nonprofit organizations together with groups focused on common missions, fundraising techniques, and channels, to better understand fundraising performance through shared data and collaborative learning. By combining comparative benchmarking with conversations among fundraising professionals, Epiphany helps participating organizations understand not just how they’re performing, but why results differ and what they might do differently.

The October discussion revealed compelling trends and practical lessons on how organizations can strengthen their sustainer programs. Here are seven takeaways worth considering.

1. Acquisition Is Only the Beginning. Retention Is Where the Real Work Happens

It’s tempting to measure the success of a sustainer program by the number of new recurring donors acquired. But acquisition volume tells only part of the story. A donor who begins giving monthly but cancels after a few payments has a very different long-term value than one who remains engaged for years.

The Epiphany benchmarking data reinforces the importance of retention. For example, digital-acquired sustainers had a median 13th-month retention rate of 64%, compared with just 20% for digital-acquired non-sustainers. That’s a substantial difference, but retention isn’t automatic. Organizations are increasingly tailoring their onboarding and stewardship experiences based on how donors were acquired. A donor recruited through face-to-face canvassing may need a different welcome experience than someone who independently signed up through a website.

Some of the most promising strategies include early welcome calls, personalized communications, donor feedback surveys, and proactive outreach to donors showing signs of attrition. These approaches recognize that acquiring a sustaining donor is the beginning of a relationship, not the culmination of a successful campaign.

The lesson: Don’t evaluate acquisition channels solely on cost per acquisition or initial gift amount. Understand how donors acquired through each channel behave over time, and build channel-specific stewardship strategies accordingly.

2. Your Payment Strategy Is Also a Retention Strategy

Payment methods may not be the most exciting topic in fundraising, but they can strongly influence sustainer retention. Among sustainers acquired in 2024, median 13th-month retention was 77% for donors giving through electronic funds transfer (EFT), compared with 56% for those using credit cards. That’s a 21-percentage-point difference worth noting.

Credit cards expire, get replaced, and sometimes have transactions declined. Even donors who fully intend to continue supporting an organization can disappear from a sustainer program because a payment fails. EFT can reduce that friction, which is why organizations are making it more prominent in donation forms, encouraging existing sustainers to switch payment methods, and improving their failed-payment recovery processes.

At the same time, convenience remains important. Digital wallets and other emerging payment methods can make giving easier, particularly for new donors. The challenge is balancing a frictionless acquisition experience with the payment methods most likely to support long-term retention.

The lesson: Payment methods shouldn’t be treated as a back-office processing decision. They’re a key part of the donor experience, retention, and lifetime value.

3. A Sustaining Gift Doesn’t Have to Be a Donor’s Only Gift

One of the most interesting findings from the benchmarking discussion challenges a longstanding assumption about recurring donors: once someone becomes a sustainer, should organizations stop asking them for additional gifts? The data suggests otherwise.

Across the participating organizations, a median 10% of sustainers made additional gifts, yet those donors accounted for a median 19% of total sustainer revenue. The difference in donor value was equally compelling. Sustainers who made additional gifts generated a median $397 in annual revenue per donor, compared with $189 for sustainers who made only their recurring contributions.

These findings reinforce something important: becoming a sustainer doesn’t mean a donor has reached the limit of their generosity. A monthly contribution may represent someone’s ongoing commitment to an organization, while a special campaign, emergency appeal, or particularly compelling opportunity can inspire additional support.

Of course, that doesn’t mean sustainers should receive every appeal an organization sends. Thoughtful segmentation, appropriate frequency, and an understanding of donor preferences remain essential. The opportunity is to recognize the broader relationship rather than treating the recurring pledge as the donor’s entire contribution.

The lesson: Stop thinking of the recurring gift as the entirety of the donor relationship. Sustainers are donors first, and their engagement with your mission can extend well beyond their monthly commitment.

4. Small Upgrades Can Create Meaningful Revenue Growth

Not every fundraising improvement requires a major new acquisition campaign. Sometimes, the opportunity is already sitting in your donor file. The benchmarking discussion explored how organizations are increasing sustainer value through targeted upgrade strategies, including traditional appeals, simplified one-click upgrades, and carefully managed automatic increases.

Even relatively modest increases in monthly giving can produce substantial additional revenue when applied across a large sustainer population. But successful upgrade strategies require more than simply asking everyone for more money. Organizations are beginning to think more carefully about donor tenure, engagement, payment history, and other indicators that might help identify donors who are ready for an increase.

The conversation also highlighted the importance of clear communication, appropriate opt-out opportunities, and monitoring retention after an upgrade. This is where predictive modeling presents an interesting opportunity. Instead of treating every sustainer the same, organizations can identify donors whose giving history and engagement suggest they’re more likely to accept an upgrade without increasing attrition risk.

The lesson: Make upgrades easy, targeted, and transparent. The objective isn’t simply to increase monthly revenue today. It’s to grow donor value without undermining retention or trust.

5. Your Best New Sustainer Might Already Be a Donor

Acquiring new sustaining donors is important, but converting existing donors into recurring supporters deserves equal attention. Benchmarking data showed that donors converted from one-time giving to monthly giving generated a median of about $90 more in annual value per donor than donors acquired directly into a monthly program.

That makes intuitive sense. An existing donor may already have years of giving history, a deeper connection to the mission, and an established pattern of responding to additional appeals. When that donor converts to recurring giving, the monthly commitment becomes another dimension of an existing relationship rather than the beginning of a new one.

Organizations are using direct mail, email, telemarketing, digital campaigns, and other channels to encourage conversion. The opportunity becomes even more interesting when organizations use their data to identify which donors are most likely to respond, rather than treating every one-time donor as an equally promising conversion prospect.

The lesson: Don’t overlook the donors who already know and support your organization. Conversion can be one of the most valuable paths to growing a sustainer program.

6. Monthly Isn’t the Only Way to Sustain

Monthly giving has become almost synonymous with sustaining giving, but the benchmarking discussion highlighted growing interest in quarterly, annual, and other recurring-gift frequencies. For some donors, an annual commitment may be more appealing than a monthly transaction. Others may prefer quarterly giving or automatic renewal of an existing membership or contribution.

The challenge is that many organizations have built their systems, reporting, and operational definitions around traditional monthly giving. As donor preferences evolve, those definitions can become unnecessarily restrictive. An organization might have donors making reliable annual commitments but lack the ability to recognize or steward them consistently as sustainers.

The discussion also raised questions about recurring commitments made through donor-advised funds and how organizations should recognize and manage those relationships. These aren’t simply technical questions. They affect how organizations identify sustainers, communicate with them, and measure long-term value.

The lesson: Think beyond the monthly pledge. Sustaining giving should reflect a donor’s ongoing commitment, not just a particular payment schedule.

7. Mature Sustainer Programs Need a Portfolio Strategy

Perhaps the most important takeaway from the meeting was that no single tactic drives a successful sustainer program. Acquisition matters, but so do conversion, retention, upgrades, additional gifts, payment recovery, and donor stewardship. And they’re all connected.

An organization might acquire more sustainers but struggle with retention. Another might have excellent retention but miss opportunities to increase donor value. A third might have a strong upgrade program but lose donors unnecessarily because of failed credit-card transactions. Looking at each activity independently makes it hard to understand the program’s overall economics.

Instead, organizations are increasingly approaching sustaining donors as a portfolio of relationships that evolve over time. That requires a more complete understanding of donor behavior, shared data across fundraising channels, and the ability to identify appropriate next steps for individual donors. It also means looking beyond individual campaign results to understand what actually contributes to long-term donor value.

The lesson: Sustainer growth isn’t one strategy. It’s the cumulative impact of many coordinated strategies, each contributing to stronger relationships and better long-term outcomes.

The Next Chapter of Sustainer Giving

The future of sustaining giving isn’t simply about convincing more people to make monthly donations. It’s about understanding what happens next. Which acquisition channels produce donors who stay? Which payment methods support stronger retention? When should a donor receive an invitation to upgrade? What makes someone more likely to give an additional gift? And how can organizations identify donors who may need attention before they lapse?

Answering those questions requires good data, but data alone isn’t enough. One of the most valuable aspects of the Epiphany Benchmarking community is the opportunity to move beyond the numbers and explore the strategies, experiences, and decisions behind them. Because the real value of benchmarking isn’t simply knowing how your organization compares with its peers. It’s understanding what you can do differently because of what you’ve learned.
