Best When

Use Cases

  • Segmenting donors for targeted campaigns from fundraising campaign agents

Not For

  • For-profit CRM without nonprofit fundraising and membership workflows
  • Grant management systems without constituent relationship components
  • Large enterprise nonprofits requiring full enterprise-grade CRM capabilities
