The Complete Guide to Donor Segmentation for Small and Medium Nonprofits in 2025
Why every nonprofit needs a strategic approach to donor communications—and how to implement it with limited resources
In a world full of passionate causes and generous donors, thoughtful segmentation helps your message reach the right people—making every connection more meaningful and every gift more likely.. Recent data from the Fundraising Effectiveness Project shows that donor retention rates remain challenging for most nonprofits, with small-dollar donors experiencing particularly steep declines in recent years. The solution? Strategic fundraising segmentation that makes every supporter feel seen, valued, and deeply connected to your mission.
List segmentation is a topic that comes up often when we talk about marketing, but it is essential to your fundraising strategy as well. Whether the communication you need to get out is a solicitation, a status update, or a thank you, there is no one-size-fits-all message that will make your donors feel seen, heard, and like they are a valuable part of your community (and they are a valuable part of your community).
The Current Landscape: Why Nonprofit Marketing Segmentation Matters More Than Ever
The nonprofit fundraising landscape is experiencing significant shifts that make donor list segmentation more critical than ever:
Declining donor numbers: According to recent data, the number of donors decreased by 1.3% year-over-year in Q1 2024, following a 10.3% drop in 2023
Increased competition: With over 1.5 million nonprofits in the U.S., donors have endless options for their philanthropic investments
Rising expectations: Today's donors expect personalized, meaningful communications that demonstrate clear impact
Generational differences: From Baby Boomers to Gen Z, each generation has distinct giving preferences and communication styles
The organizations thriving in this environment aren't necessarily those with the biggest budgets—they're the ones that invest in understanding their donors as individuals and crafting targeted communications that resonate.
Before You Begin: Assess Your Fundraising Database Capabilities
Before you can dive into the strategy behind your nonprofit donor segmentation, you need to understand your technical fundraising capabilities. This foundational step will determine your approach and set realistic expectations for your segmentation efforts.
Key questions to answer:
What's your current system? Are you operating out of an Excel spreadsheet, a basic donor database, or a comprehensive CRM system?
What data can you access? What types of reports are you able to pull? What fields are consistently populated in your database?
How can you sort and filter? What are the qualifiers by which you are able to segment your list? Can you combine multiple criteria?
What's your automation capacity? Can segmentation and email deployment be automated accurately, or will it need to be done manually?
What's your bandwidth? How much time can your team realistically dedicate to creating and managing segmented communications?
Having the answers to all of these questions in advance will save you a great deal of time and prevent frustration as you brainstorm about the messages you want to send and how best to deliver them.
Pro tip for small nonprofits: If you're still using spreadsheets, consider this your sign to invest in donor management software. Even platforms like MailChimp (they offer nonprofit pricing) or DonorPerfect’s starter plans can dramatically improve your segmentation capabilities and are often more affordable than you think.
The 8 Essential Segmentation Strategies for 2025
Once you know what kinds of data you'll be able to use to segment your donor list, you can really dive into your work around the variety of messages you want to send. Here are the most effective segmentation strategies, updated for today's fundraising landscape:
1. Gift Size and Capacity
This remains one of the most fundamental and effective segmentation strategies. What do your major donors need to know or hear that is different from the donors who gave $25 at year-end? Consider these gift-based segments:
Major gift donors: Insider updates, exclusive events, direct access to leadership
Mid-level donors: Impact stories, program deep-dives, upgrade opportunities
General donors: Accessible giving opportunities, peer fundraising invitations, volunteer opportunities
Monthly donors: Consistent stewardship, annual impact reports, exclusive monthly donor perks
2025 insight: With small-dollar donors experiencing a 12.4% year-over-year drop, focus on converting one-time small gifts to monthly recurring donations. Include monthly giving options on all donation forms and use targeted messaging to existing small donors about the power of consistent support.
2. Geographic Location
If you serve multiple communities or have supporters nationwide, location-based segmentation can significantly improve engagement rates. Consider:
Local supporters: Volunteer opportunities, local events, community-specific impact stories
Regional donors: Regional program updates, area-specific challenges and successes
National supporters: Broader organizational updates, national advocacy opportunities
Example in action: An animal shelter might send local supporters information about upcoming adoption events, while sending distant donors stories about animals they've helped find homes nationwide.
3. Engagement and Relationship Length
Tailor your communications based on how long donors have been with you and how engaged they are:
New donors (0-12 months): Welcome series, mission education, program introductions
Established donors (1-5 years): Impact updates, deeper program information, leadership opportunities
Legacy supporters (5+ years): Insider information, planned giving opportunities, advisory roles
Lapsed donors: Re-engagement campaigns, "we miss you" messages, easy return pathways
2025 strategy: Focus heavily on new donor retention, as first-year donor renewal rates often determine long-term relationship success. Create a structured 12-month new donor journey with touchpoints at 30, 60, 90, and 180 days.
4. Program Interest and Passion Areas
This segmentation is increasingly important as donors want to see specific impact from their investments:
Program-specific donors: Updates and stories from their area of interest
General operating supporters: Organizational updates, behind-the-scenes content
Capital campaign donors: Construction updates, naming opportunities, completion milestones
Emergency response givers: Crisis updates, immediate needs, rapid response opportunities
Implementation tip: Use donation forms, surveys, and event attendance to gather program interest data. Even a simple "What aspect of our work interests you most?" question can provide valuable segmentation data.
5. Communication Preferences and Channel Behavior
Understanding how donors prefer to receive information is crucial for engagement:
Email-responsive donors: Detailed newsletters, impact reports, online giving links
Direct mail responders: Physical thank you notes, printed newsletters, mail-based appeals
Social media engaged: Instagram stories, Facebook Live events, peer-to-peer campaigns
Event attendees: In-person gatherings, exclusive events, community building opportunities
2025 trend: Multi-channel donors (those who engage across platforms) show higher retention rates and larger lifetime value. Track cross-channel engagement and reward it.
6. Giving Behavior and Patterns
Segment based on when and how donors typically give:
Year-end givers: December campaigns, tax-benefit messaging, year-end impact reports
Monthly donors: Consistent stewardship, annual cumulative impact stories, exclusive perks
Event donors: Event invitations, sponsorship opportunities, social fundraising tools
Peer-to-peer fundraisers: Fundraising toolkits, peer recruitment opportunities, social sharing content
7. Relationship Connections
Think about the staff, board member, or volunteer to whom the donor is most connected:
Board-connected donors: Messages from board chair, governance updates, strategic planning input
Staff-connected donors: Updates from specific program directors, behind-the-scenes content
Volunteer-recruited donors: Volunteer impact stories, volunteer recruitment opportunities
Event-met donors: Follow-up from event hosts, similar event invitations
Pro tip: Track the "source" of each donor relationship in your database. This information is gold for personalized stewardship.
8. Generational Segmentation (New for 2025)
Different generations have distinct giving preferences and communication styles:
Baby Boomers (1946-1964): Traditional direct mail, phone calls, formal events, legacy giving focus
Generation X (1965-1980): Email newsletters, online giving, family-focused messaging
Millennials (1981-1996): Social media, peer-to-peer campaigns, impact transparency, cause alignment
Generation Z (1997-2012): Social platforms, video content, social justice messaging, peer influence
2025 data insight: Gen Z comprises 20.7% of the population with 44% giving an average gift of $785 to 3 charities. They're motivated by trust, mission alignment, and evidence of community impact.
Advanced Segmentation Strategies for Growing Organizations
As your nonprofit matures and your database grows, consider these sophisticated approaches:
Lifetime Value Segmentation
Group donors by their total giving history and potential:
High lifetime value: VIP stewardship, planned giving cultivation, advisory opportunities
Growing value: Upgrade campaigns, increased engagement opportunities
Declining value: Re-engagement strategies, feedback surveys, win-back campaigns
Predictive Segmentation
Use data analytics to identify:
Major gift prospects: Donors showing increased engagement or capacity indicators
Lapse risk donors: Supporters showing declining engagement patterns
Monthly giving candidates: One-time donors with consistent small gift patterns
Legacy prospects: Long-term donors approaching traditional planned giving ages
Behavioral Trigger Segmentation
Create automated segments based on specific actions:
Website visitors: Follow up with relevant content based on pages viewed
Event no-shows: Alternative engagement opportunities, recorded content access
Social sharers: Peer-to-peer fundraising opportunities, ambassador programs
Survey responders: Tailored follow-up based on interests expressed
Making Segmentation Work with Limited Resources
Start small and scale: Begin with 3-4 basic segments (like gift size and relationship length) and add complexity as you build capacity.
Use automation wisely: Even basic email platforms offer segmentation features. Set up automated welcome series for new donors and thank you sequences for different gift levels.
Batch your work: Rather than creating individual messages, develop templates for each segment that can be customized with specific details.
Track what works: Monitor open rates, click-through rates, and giving responses by segment. Double down on what's working and adjust what isn't.
Leverage volunteers: Train dedicated volunteers to help with segmentation tasks like data entry, list management, and even content creation for specific segments.
The Foundation: Clean, Actionable Data
The key to making list segmentation work is good, clean data. Here's what you need to prioritize:
Essential data points to collect and maintain:
Complete contact information (with preferences noted)
Giving history with dates, amounts, and designations
Engagement history (events attended, emails opened, etc.)
Relationship connections (how they found you, who they know)
Communication preferences (email vs. mail, frequency preferences)
Interest areas and program preferences
Data hygiene best practices:
Regular database cleanup (quarterly at minimum)
Standardized data entry procedures
Duplicate record management
Consistent naming conventions
Regular backup procedures
Quick data quality check:
Can you answer these questions about your top 20 donors from your database in under 5 minutes?
How did they first connect with your organization?
What's their largest gift and when did they give it?
When did they last engage with you (beyond giving)?
What program area interests them most?
If you can't easily access this information, it's time to invest in data cleanup and standardization.
