How do we segment our list? We need a tool that separates volunteers, donors, and board members but shows their overlap.

To separate volunteers, donors, and board members while mapping their exact overlaps, you need a Nonprofit CRM (Constituent Relationship Management) or a flexible data visualization tool that supports multi-tagging or Venn/Euler-style intersection reporting.

Because people often wear multiple hats in non-profits (e.g., a donor who also volunteers and sits on the board), a rigid folder-based list structure won't work. You need relational tagging.

Recommended Tools for Overlap Segmentation

1. Nonprofit CRMs with Advanced Tagging & Venn/Intersection Reports
   • Bloomerang / Little Green Light / DonorPerfect: These platforms allow you to assign multiple "roles" or "constituent types" to a single profile. Instead of putting someone in a single box, you run custom reports (e.g., Show me contacts where Constituent Type = Board Member AND has lifetime giving > $0).
   • Salesforce NPSP (Nonprofit Success Pack): The gold standard for complex relationship mapping. You can use reports and dashboards with Venn-like matrix logic, or connect it to visual analytics.
2. Visual Overlap & Charting Tools (If your CRM lacks Venn capabilities)
   • Canva or Creately : If you already have the data exported from a spreadsheet (Excel/Google Sheets) and just need a visual representation, you can use a Creately Venn Diagram Maker or a Dynamic Venn Diagram Template in Excel to plug in the counts for each segment (Volunteers only, Donors only, Board only, and the overlapping intersections).
   • Tableau / Microsoft Power BI: If you want a dynamic dashboard where clicking the "Donor + Volunteer" intersection instantly pulls up the list of names, feeding your CRM data into Power BI or Tableau will give you fully interactive Venn/Euler or intersection diagrams (using UpSet plots).creately.com[2]

How to Structure Your Data (Step-by-Step)

If you are setting this up in a spreadsheet or CRM right now, use this method:

1. Use Boolean/Checkbox Fields Instead of a Single Category Column:
   • Instead of a column called Role that says "Donor," create three separate true/false (checkbox) columns:
     • Is_Donor (True/False)
     • Is_Volunteer (True/False)
     • Is_Board_Member (True/False)
2. Create Intersection Segments via Filtering:
   • Segment A (Pure Donors): Is_Donor = True AND Is_Volunteer = False AND Is_Board_Member = False
   • Segment B (Volunteer Donors / Overlap): Is_Donor = True AND Is_Volunteer = True AND Is_Board_Member = False
   • Segment C (Triple Threat - Board, Donor, & Volunteer): Is_Donor = True AND Is_Volunteer = True AND Is_Board_Member = True

To help narrow down the best tool or formula setup for your team, tell me:

• How many total records are in your current database?
• What software or platform (Excel, Google Sheets, or a specific CRM) are you currently using to store this data?

Yes. What you want is a single constituent database with multi-select roles, rather than three separate lists. That lets one person simultaneously be a volunteer, donor, and board member, while your reports show both the individual groups and their intersections. Salesforce’s nonprofit guidance explicitly recommends allowing contacts to belong to multiple categories, and several nonprofit CRMs now support this model.Salesforce+1

The segmentation structure

Use one record per person, with independent role/status fields:

Then create saved segments such as:

• Volunteers only
• Donors only
• Board members only
• Volunteer + Donor
• Donor + Board
• Volunteer + Board
• Volunteer + Donor + Board
• None of the three
• Any of the three

The important design choice is not to make "Donor," "Volunteer," and "Board" mutually exclusive categories. They're attributes that can coexist. Salesforce specifically recommends this approach, and its guidance notes that activity-based information can also be used to create segments.Salesforce

Tools worth looking at

If you're choosing a system rather than building this in your existing CRM, I'd shortlist:

• DonorPerfect — combines donor, volunteer, and prospect data and supports custom fields, reporting, and role-based permissions.DonorPerfect
• Givebutter — supports contact tags such as Volunteer and Board Member, custom fields, and filtering across them.Givebutter
• Bloomerang — offers constituent segmentation and connects donor/volunteer information in its platform.Bloomerang
• CauseVox — has a connected constituent record with tags, custom fields, relationships, and live segments.CauseVox
• — particularly interesting if volunteer management is as important as fundraising; it describes unified profiles for volunteers, donors, board members, and others with automatic segmentation.

If the main requirement is "show me the overlap," I'd prioritize a CRM with one unified person record + multi-value roles + saved/dynamic segments, rather than a volunteer-management system and donor database that merely exchange spreadsheets.

If you tell me what you're using today (e.g., Salesforce, EveryAction, Bloomerang, NationBuilder, spreadsheets, Mailchimp, etc.) and roughly how many contacts you have, I can narrow this to the most practical setup and show you exactly how I'd structure the fields and overlap reports.

You’re looking for a constituent relationship management (CRM) tool with multi-role segmentation — not three separate lists. The key feature is that one person can have multiple roles at the same time (for example, “Volunteer + Donor” or “Board Member + Donor + Volunteer”) while keeping a single contact record.Salesforce

A good setup would look like this:

1. Use one master contact record

Each person is a single record:

Then you can create segments such as:

• All volunteers
• First-time donors
• Donors who have volunteered
• Board members who have donated
• People in all three groups
• Volunteers who have never donated

2. Look for these CRM capabilities

Prioritize tools that support:

• Tags or relationship types (Volunteer, Donor, Board Member, Alumni, Sponsor, etc.)
• Multiple categories per contact (not a single “contact type” field)
• Custom reports and filters
• Interaction history (gifts, volunteer hours, meetings, event attendance)
• Duplicate merging so the same person is not split across databases

Salesforce’s nonprofit guidance specifically describes using categories so contacts can belong to multiple groups, such as being both a donor and volunteer.Salesforce

3. Tools to consider

• Salesforce — Strong for complex organizations that need detailed relationship mapping, reporting, and custom workflows. Its nonprofit tools support categorizing contacts into overlapping roles.Salesforce
• Donorbox — Useful if fundraising is central and you want donor insights plus broader supporter information.Donorbox
• Pipedrive — A general CRM that can be configured for nonprofit relationship tracking with custom fields and segmentation.Pipedrive
• DonorDock — Focused on donor management with custom fields, segmentation, and activity tracking.DonorDock

4. If you want a visual “overlap” view

Ask vendors to demonstrate:

• A Venn diagram or overlap report (donor-only vs volunteer-only vs both)
• A query like: “Show all donors who volunteered at least 10 hours last year”
• A query like: “Show all board members who have never donated”
• A timeline showing every person’s relationship with your organization

Many nonprofits start with simple tags and filters, then add dashboards once the data structure is clean.Moregoodtogether2.0

If you tell me your organization size (e.g., under 5,000 contacts vs 100,000+) and whether you already use a donor system or volunteer platform, I can narrow this to a few best-fit options.

Yes. What you’re describing is a nonprofit CRM with role-based segmentation, where “volunteer,” “donor,” and “board member” are overlapping attributes of the same person—not three separate lists.

A good structure would look like:

• Donor — giving history, amount, frequency, last gift, campaign
• Volunteer — hours, roles, interests, participation
• Board member — current/former status, committee, term dates
• Shared constituent record — one person, with all three roles attached

That lets you create segments such as:

• Donors who also volunteer
• Donors who are board members
• Volunteers who aren't donors
• Board members who are donors
• People who are all three
• Former board members who are active donors
• High-engagement volunteers who haven't donated

This “one person, multiple relationships” model is specifically recommended for nonprofit CRM design because separating donors, volunteers, and other roles into independent databases makes overlap difficult to see.Solving Dynamics 365+1

Tools I'd look at

Donorbox CRM is worth considering if fundraising is the center of your operation. It supports dynamic lists/segmentation and says its CRM can provide a broader view including donors, volunteers, and board members.Donorbox

More Good Together is particularly aligned with your description: it explicitly supports donors, volunteers, board members and other relationship types on a single constituent record, with tags and segments based on those relationships.Moregoodtogether2.0+1

Dynamics 365 for Nonprofits is the more enterprise-oriented route. Its constituent model treats roles as relationships attached to a person and supports segmentation based on donor and volunteer activity.Solving Dynamics 365+1

The key feature to insist on

Don't buy something that merely lets you make three lists called Donors, Volunteers, and Board.

You want a database where the underlying logic is:

Person → multiple roles → multiple activities

That way, the overlap is automatically visible rather than something your staff has to reconcile manually.glueup.com+1

If you tell me roughly how many contacts you have and what you currently use for donations/volunteers/email, I can narrow this to 2–3 tools that fit your organization and compare pricing, segmentation, and overlap reporting.

To cleanly separate volunteers, donors, and board members while visualizing their exact overlaps, you need a Constituent Relationship Management (CRM) system with robust tagging/segmentation , paired with reporting or data visualization tools.

The best approach relies on a single database where people have multiple attributes, rather than separate lists. Here is how to set up the system and the tools that handle this best:

Recommended Tools for Overlap Analysis

1. Nonprofit CRMs with Advanced Filtering & Tagging
   • Examples: Bloomerang, DonorPerfect, Salesforce Nonprofit Cloud / NPSP , or Givebutter.
   • How it works: Instead of putting a contact in separate folders, every person is a single profile. You assign them multiple tags or roles (e.g., Volunteer, Donor, Board Member ). You can then run a Venn-style matrix report or a multi-criteria filter (e.g., "Show me contacts where Role = Board Member AND Giving History > $0") to instantly isolate the overlap.monkeypod.com+1
2. Data Visualization & Venn Diagram Tools (For Visualizing the Overlap)
   • Examples: Venngage Venn Diagram Maker or [Lucidchart / Miro].
   • How it works: Once you pull the numbers from your CRM (e.g., 50 pure volunteers, 100 pure donors, 5 board members who also donate, 2 board members who also volunteer), you plug those counts into a 3-way Venn diagram template to present a clear visual to leadership.venngage.com+1
3. Business Intelligence (BI) Connectors
   • Examples: Tableau or Power BI connected to your CRM.
   • How it works: For advanced needs, these tools build dynamic, auto-updating Euler/Venn diagrams or intersecting set charts directly off your live database.

Step-by-Step Segmentation Strategy

1. Centralize the Data: Ensure a single contact record exists for each person. John Doe should not have a separate volunteer profile and donor profile.
2. Apply Multi-Select Attributes: Tag profiles with categorical labels: [Role: Volunteer], [Role: Donor], [Role: Board].
3. Run Intersect Queries: Use your CRM's "Advanced Search" or "Report Builder" to create intersection segments:
   • Segment A: Volunteers only
   • Segment B: Donors only
   • Segment C: Board members only
   • Intersect A+B: Volunteers who donate
   • Intersect B+C: Board members who donate (and so on)

To help narrow down the right platform, tell me:

• What is your approximate budget?
• What CRM or database are you currently using (if any)?

What you’re describing is a relationship-based segmentation tool, not just separate lists. You want each person to have multiple roles, with the ability to see intersections (for example: “board members who donate,” “volunteers who have never given,” or “donors who also volunteer”).

A good setup looks like this:

1. Use one master contact record

Avoid three separate databases. Create one person record with role fields/tags:

This allows overlap reporting instead of forcing people into one category.

2. Use tags or relationship fields

Create fields such as:

• Roles - Volunteer
• Donor
• Board Member
• Former Board Member
• Event Attendee
• Advocate
• Engagement details - Volunteer hours
• Last donation date
• Lifetime giving
• Board term dates
• Committee membership
• Interests - Programs supported
• Skills
• Communication preferences

Many nonprofit CRMs support custom tags, fields, and saved segments for exactly this kind of filtering.DonorDock+1

3. Look for overlap/visual segmentation features

The tool should answer questions like:

• “Show everyone who is a volunteer AND donor”
• “Show board members who have never donated”
• “Show donors who volunteered in the last year”
• “Show people with any two of the three roles”

Some systems provide dynamic lists/segments that update automatically as records change.Donorbox

Tools to consider

• Salesforce with nonprofit-focused configuration — very flexible if you need complex relationships and reporting.
• Blackbaud products such as Raiser’s Edge NXT — built around fundraising relationships and constituent management.
• DonorPerfect — supports centralized supporter records, custom fields, reporting, and segmentation.DonorPerfect
• Bloomerang — commonly used for donor relationship management and engagement tracking.
• DonorDock — offers tags, segments, and tracking across donor/volunteer activity.DonorDock

The key feature to ask vendors about

Ask: “Can one constituent belong to multiple groups and can we report on intersections between those groups without exporting to spreadsheets?”

If the answer is no, it’s probably a list manager rather than a true relationship CRM.SimpliPhi

If you tell me your organization size (e.g., 500 contacts vs. 50,000) and whether you already use a CRM, I can narrow this down to a few best-fit options.

To properly segment your list and visualize the exact overlap between Volunteers, Donors , and Board Members , you need a 3-set Venn diagram or an intersection-capable database tool . A 3-circle Venn diagram creates seven distinct regions , letting you see who belongs to just one group, who bridges two groups (e.g., Donor + Volunteer), and your core "triple threats" right in the center.conceptviz.app+1

1. Choose the Right Tool for the Job

• For Data Visualization (The Overlap):
  • Use a digital whiteboard or diagram tool like the Miro 3-Circle Venn Diagram Template or Canva's Venn Diagram Maker to visually map out numbers or names.
  • Use a mathematical/data calculator like the Statistics Kingdom Venn Diagram Maker if you want to plug in exact counts for each segment and calculate proportional overlaps.canva.com+3
• For Data Management (The Source List):
  • Use a nonprofit CRM (like Bloomerang, Little Green Light , or Kindful ) utilizing Tags or Constituent Codes . Instead of forcing a contact into a single folder or category, assign multiple tags (e.g., Tag: Volunteer, Tag: Donor, Tag: Board ). You can then run a multi-tag filter or Venn report to pull up the exact cross-sections.youtube.com+1

2. The 7 Segments You Need to Map

When you set up your tool, structure your categories into these exact 7 intersection zones:

1. Volunteers Only: People who give their time but haven’t financial-donated or served on the board.
2. Donors Only: Pure financial supporters who haven't volunteered hands-on.
3. Board Members Only: Rare, but administrative/governing members who have yet to donate personally or volunteer for standard shifts (though hopefully zero!).
4. Volunteers + Donors: Your grassroots champions who give both money and time.
5. Donors + Board Members: Financial stakeholders who sit on governance but don't log physical volunteer hours.
6. Volunteers + Board Members: Working board members who roll up their sleeves for events/operations but haven't financially donated (yet).
7. The Center (Volunteers + Donors + Board Members): Your ultimate super-supporters. These individuals give time, money, and leadership—your prime candidates for major gifts or future legacy campaigns.

If you'd like, tell me:

• How many total contacts are in this list?
• What software/platform (Excel, Google Sheets, a specific CRM) your data currently lives in?

I can give you a step-by-step formula or filtering guide to extract these 7 overlapping groups automatically.
