Donor Lists & Fundraising Data for Nonprofits

A group of people holding hands in the shape of hearts.

Reach passionate supporters and boost donations with Gemstone Data’s targeted donor lists. We help nonprofit organizations, charities, and fundraising teams connect with individuals who are most likely to give — based on their interests, donation history, and cause affinity.

Precision Donor Targeting

Every successful fundraising campaign starts with knowing your audience. Our cause-based donor databases are segmented by interests, demographics, and giving behavior — helping you build campaigns that resonate and inspire action.

Segment Donors By:

  • Cause affinity: environmental, religious, political, humanitarian, and more
  • Demographics: age, income, homeownership, gender, and location
  • Giving capacity: household income and wealth indicators

With Gemstone Data, you can identify supporters who share your mission and tailor your outreach for higher engagement and stronger results.

Multi-Channel Fundraising Made Easy

Direct Mail Campaigns

Personalized mail remains one of the most effective channels for nonprofit fundraising. Use our donor lists to send impactful letters, event invitations, or donation appeals to cause-aligned households.

Telemarketing Outreach

Engage directly with supporters through outbound calls. Our accurate donor telemarketing lists allow you to reach individuals who are receptive to your mission — helping you secure more pledges, renewals, and recurring gifts.

Email Fundraising

Connect instantly with segmented donor audiences through targeted email campaigns. Our email-ready donor lists are ideal for newsletter updates, event promotions, and end-of-year giving drives.

Geofence Marketing for Events & Awareness

Take your outreach to the next level with addressable geofencing. Display mobile ads to potential donors near your charity events, community centers, or partner locations — creating timely, localized engagement that drives participation and giving.
