What Is Donor Segmentation, and How Should Small Nonprofits Use It?

Your nonprofit is preparing its next fundraising email. The message is written, the campaign is ready, and someone has exported the donor list. Everyone gets the same email because, well, everyone is on the donor list. Seems efficient enough until you remember that one person donated for the first time yesterday, another has been giving $15 every month for three years, and someone else contributed once to a friend's birthday fundraiser back in 2022.

Now imagine all three receiving an email that begins, "It's been a while since we've heard from you."

You can probably see the problem, right?

Small nonprofits often have enough information to communicate with supporters more thoughtfully. They know who donated, when they gave, and sometimes even which programs interested them. Unfortunately, that information tends to sit in spreadsheets or donor databases until someone needs to prepare a report.

Donor segmentation helps organizations put those records to use. And despite how technical the term sounds, you don't need a fundraising department or expensive software to begin.

What Is Donor Segmentation?

Donor segmentation is the practice of organizing supporters into smaller groups based on information they have in common. These groups might reflect giving history, donation frequency, program interests, or how someone prefers to communicate with your organization.

For example, a nonprofit might identify first-time donors, recurring monthly supporters, and people who haven't contributed recently. Each group has a different history with the organization, so sending everyone identical fundraising messages may overlook useful information about those relationships.

The Association of Fundraising Professionals (AFP) identifies several useful ways to segment donor records, including how recently someone contributed, how frequently they give, why they supported an organization, and what kind of relationship they have with it.

Consider two supporters of a community literacy nonprofit.

Marissa donated $25 after attending the organization's reading workshop. It was her first contribution, and she's still learning about the nonprofit's programs. Daniel, meanwhile, has supported the same organization through monthly donations for several years.

The nonprofit could send Marissa a welcome message introducing its ongoing programs and explaining what her contribution helped support. Daniel might appreciate an update recognizing his continued support and showing how the literacy program has progressed over time.

Both deserve appreciation and accurate information. Their communication can simply reflect what the organization already knows about them.

That's essentially how donor segmentation works.

Why Should Small Nonprofits Segment Their Donors?

One reason is that fundraising totals don't always tell you much about the people behind those contributions.

According to the Fundraising Effectiveness Project's first-quarter 2026 findings, total charitable dollars raised increased by an estimated 4.3% compared with the same period in 2025, while the estimated number of donors declined by 0.8%.

Those are sector-wide estimates for a specific reporting period, and they don't establish whether donor segmentation improves fundraising results. They do illustrate why organizations should look beyond total revenue when examining their donor relationships.

Imagine a small nonprofit raises $60,000 this year, compared with $50,000 last year. That's encouraging. But perhaps the additional revenue came from a few larger contributions while the number of individual supporters decreased. Without examining the donor records, the organization could easily miss that development.

Segmentation makes it easier to investigate questions such as:

• Are first-time donors returning after their initial contributions?

• How many supporters give regularly, and how many contribute only during specific campaigns?

• Which donors have stopped giving but remain involved through volunteering or events?

• Are supporters receiving communications relevant to their interests and relationship with the organization?

The answers can help a nonprofit decide where to direct its limited time.

A team with two employees probably cannot personally contact 300 supporters every month. It can, however, identify a smaller group of first-time donors who need a welcome message or recurring donors who should receive an update about a program they have supported.

AFP's 2025 guidance on using donor data in small organizations recommends beginning with approximately three to five meaningful donor groups rather than building an elaborate segmentation system.

That's a reasonable starting point. Creating twenty separate audience categories would be an impressive amount of administrative work for a nonprofit that hasn't yet decided what to do with the first four.

What Types of Donor Segmentation Should Small Nonprofits Use?

There are several ways to organize donor records, but the most useful criteria depend on the decisions your organization needs to make.

1. Segment by Giving History

Start with the information you probably already have: donation dates, amounts, and frequency.

A common fundraising approach examines three characteristics, often referred to as RFM:

• Recency: How recently someone made a contribution.

• Frequency: How often they contribute within a defined period.

• Monetary value: How much they have contributed, whether measured through individual gifts or giving totals.

These characteristics can help identify donors who contribute regularly, supporters who make occasional gifts, and people whose giving patterns have changed.

For a small nonprofit, however, you don't necessarily need to calculate a sophisticated RFM score. You might begin by separating people who have made one contribution from those who have supported the organization repeatedly.

Be sensible about the conclusions you draw. Someone who donates $20 every month may have a stronger ongoing giving pattern than someone who contributed $500 once. Both contributions are valuable, but their records tell you different things about how they currently support the organization.

2. Segment by Donor Relationship

Donors can also be grouped according to where they are in their relationship with the nonprofit.

These categories should follow clear rules within your organization's database.

For example, a nonprofit might flag donors who haven't contributed in the past twelve months for review. But, that doesn't automatically mean those people have disengaged. Someone who typically donates every December may still be following their usual giving schedule when the organization reviews its records in October.

Likewise, a person who stopped donating but continues volunteering remains involved with the organization.

A giving-history report tells you what the records show. Understanding the relationship may require looking at other activities or speaking with the supporter.

3. Segment by Program Interest

Suppose your nonprofit runs three programs: children's literacy, adult education, and community tutoring.

Some donors may have expressed interest in one program, while others support the organization's broader mission. If someone specifically asks to receive updates about adult education, your team can record that preference and use it when planning communications.

Interest can also be informed by information the donor voluntarily provides, such as a response to a survey or an explicit request for updates about a particular initiative.

However, don't assume that a person's contribution to one campaign establishes everything they're interested in.

A donor who gives to a children's literacy fundraiser may also care deeply about adult education. Perhaps the literacy campaign was simply the first one they encountered.

The AFP's introduction to donor data segmentation specifically discusses the importance of understanding why people give, because donors with similar contribution amounts may have entirely different reasons for supporting an organization.

When that information isn't available, it is best to leave it unknown. Your database doesn't need an invented explanation for every donor's motivations.

4. Segment by Communication Preferences

Some supporters prefer email updates, while others respond better to mailed letters or direct conversations. Some want frequent program news, and others prefer less communication.

If someone explicitly tells your organization how they would like to be contacted, record that preference and respect it.

You can also distinguish between people who have agreed to receive fundraising communications and those whose information was collected solely to process a transaction.

The AFP's Principles of the eDonor Bill of Rights emphasize informing online donors about how their information will be used, protecting their privacy, and respecting choices about unsolicited communications.

Communication permissions are subject to applicable laws, which can differ by jurisdiction and message type. An organization's practices should account for those requirements alongside the preferences recorded in its systems.

A Practical Example: Segmenting 100 Donors

Let's say a small nonprofit called the Community Reading Initiative has 100 people in its donor records. Its team includes an executive director, a program coordinator, and one administrator who also handles fundraising communications.

The organization wants to improve how it communicates with donors but doesn't have time to maintain dozens of separate email campaigns.

After reviewing its records, the team creates four groups.

This is a fictional example. The numbers demonstrate how a small nonprofit could organize its records, not industry averages or recommended donor proportions.

For this example, the groups are mutually exclusive. Active recurring donors are classified first, followed by recent first-time donors, returning non-recurring donors who gave within the past year, and finally those without a recorded contribution during that period.

In an actual database, donors can have multiple characteristics. Someone might be a recurring donor, a volunteer, and a supporter of the adult education program. The organization can maintain those characteristics as separate tags while selecting one primary communication group for a particular campaign.

Now suppose the literacy program has completed its first ten reading sessions.

The team already has one verified program update. Rather than writing four entirely different newsletters, it can adapt the introduction and next steps according to the relationship.

• For first-time donors, the message could briefly introduce the program and explain what has happened since their contribution.

• For recurring donors, it could recognize their ongoing support before sharing the same program results.

• For returning donors, it could acknowledge their previous involvement and provide an update on recent progress.

• For donors who haven't contributed recently, the team might first review whether the original gift was tied to a one-time event, whether the person has expressed an interest in staying involved, and whether another message would be appropriate.

The program information remains consistent. The organization simply considers what the recipient already knows and why the communication might be relevant.

If you've already established a donor stewardship process, segmentation can help organize who receives particular communications and when. The two practices work together, provided the information being shared is accurate and the organization's commitments to donors are respected.

How Can You Segment Donors Without a CRM?

You can begin with a spreadsheet.

In fact, AFP's guidance for small nonprofit teams specifically identifies basic gift histories, engagement activities, and donor profiles as useful starting information, even when an organization doesn't have a sophisticated database.

The bigger concern is whether your information is accurate and organized well enough to use.

If you have several spreadsheets containing overlapping donor records, the first job is to identify which records belong to the same people and where the most reliable contribution information is stored.

Step 1: Organize the information you already have

A basic donor tracking system might include these fields:

Keep the underlying contribution transactions as well, rather than relying exclusively on manually updated totals. Each gift should have its own record so that staff can trace dates, amounts, campaigns, and corrections when preparing reports.

You can then use spreadsheet filters, formulas, or pivot tables to identify donors who meet particular criteria.

If the organization already has a nonprofit CRM, those same criteria can usually be applied through contact fields, reports, filters, or saved audiences, depending on the software.

Step 2: Choose a few useful groups

Before creating a new segment, decide what your team intends to do with it.

• If the organization wants to improve communication with first-time donors, it needs a reliable way to identify people making their first contributions.

• If the goal is to review monthly giving relationships, the team needs accurate recurring donation records.

There may be little reason to create a separate segment for supporters who donated on a Tuesday unless your organization has some genuinely useful reason to analyze that information.

A segment earns its place in the system when it helps staff make an informed decision or perform a defined follow-up.

Step 3: Decide who maintains the records

This is easy to overlook, especially when multiple employees handle fundraising.

Someone needs to record new donations, correct duplicate contacts, update communication preferences, and review whether donors still belong in their assigned groups.

For small nonprofits, those tasks can be incorporated into existing donation processing and fundraising routines. The organization should assign responsibility clearly so that records don't depend on someone remembering to update a spreadsheet whenever they have spare time.

Step 4: Prepare communications for each group

Begin with one campaign or update. Identify its purpose, select the appropriate audience, and determine what information needs to change for each group.

You may only need to adjust a paragraph or two. If the nonprofit has already prepared an accurate program update, there is no reason to rewrite every factual detail for each segment.

Before sending, review the final recipient lists for duplicate contacts, outdated addresses, communication preferences, and people who should be excluded.

Step 5: Review what happened

Once the communications have been sent, examine the results.

Depending on the campaign and available records, you might review:

• The number of messages successfully delivered.

• Replies, questions, or feedback received.

• Attendance at events or other engagement opportunities.

• Contributions received after a fundraising appeal.

• Changes in donor participation over subsequent comparable periods.

Treat these as indicators that need interpretation. If a group contributes more after receiving a particular message, that alone doesn't establish that segmentation caused the increase. Campaign timing, donor circumstances, and other factors may have influenced the results.

For smaller organizations, even reviewing which groups received useful responses and which messages generated confusion can help improve the next communication.

What Mistakes Should Nonprofits Avoid When Segmenting Donors?

The first is creating categories that are too complicated to maintain.

If your organization has 120 donors and one employee responsible for communications, building thirty separate segments may leave that person with more administrative work than before. Start with the groups you can manage and expand when there's a useful reason.

Another common problem is relying on records that haven't been reviewed. If your database contains duplicate contacts, incorrect donation dates, or outdated communication preferences, the resulting segments may be inaccurate.

That can lead to awkward situations, such as sending a first-time donor welcome email to someone who has supported the organization for years.

There's also the temptation to give all the attention to donors who contribute larger amounts.

Gift size can be relevant when planning fundraising activities and assigning staff time, but it shouldn't determine whether someone receives basic appreciation, accurate information, or respectful treatment. Smaller contributions may represent meaningful commitments from the people making them.

Finally, organizations should avoid collecting personal information they don't need. Donor segmentation doesn't require guessing someone's wealth, political beliefs, family circumstances, or private motivations.

The AFP Code of Ethical Standards addresses the protection of confidential donor information and the responsible management of donor records. Staff should work with information they have a legitimate reason to maintain, using appropriate access controls and respecting donors' preferences.

A smaller, accurate database is considerably more useful than a detailed one filled with guesses nobody can verify.

How Do You Know Whether Your Donor Segmentation Is Working?

A practical way to evaluate segmentation is to compare the organization's communication and fundraising records over time.

For example, if you've created a first-time donor segment, review how many people in that group make another contribution during a defined follow-up period. Compare the results with previous periods where possible, while accounting for differences in campaigns and donor circumstances.

If you've created a recurring donor segment, review whether those supporters are receiving appropriate updates and whether their payment or communication concerns are being addressed.

If you've identified donors who haven't contributed recently, investigate whether they remain involved through other activities before deciding what follow-up is suitable.

Your measures should reflect the purpose of each group.

A segment designed to improve program communication might be evaluated through donor feedback and whether promised updates are delivered. A segment created to support a fundraising appeal may be assessed using contributions, response rates, and the cost of the campaign.

The organization should also consider how much staff time segmentation requires. If maintaining the system consumes several hours every week without producing information that anyone uses, the process may need simplifying.

Start With the People Already Supporting Your Work

If your nonprofit has been sending the same fundraising message to everyone on its contact list, there's no need to rebuild the entire database before trying something different.

Begin by reviewing the information you already maintain. Identify first-time donors, recurring supporters, and people whose giving patterns may need attention. Look at the interests and communication preferences supporters have actually shared, then decide which groups would benefit from different follow-ups.

You may discover that several donors have contributed for years without receiving much information beyond receipts and fundraising appeals. Others might be receiving messages about programs they've never expressed an interest in.

Those are useful things to discover before preparing the next campaign.

Donor segmentation gives small nonprofits a more organized way to work with their existing relationships. You can begin with a few spreadsheet filters, a clear follow-up process, and someone responsible for keeping the information accurate.

And if your team is already overwhelmed, please don't begin by creating fourteen donor categories, seven automated email sequences, and a dashboard that requires its own instruction manual.

Start with three or four groups you understand, and make sure somebody knows what to do with them. The rest can come when your organization actually needs it.
