Treat outreach as relationship- and opportunity-driven: prepare a concise briefing that ties an organization's work to the foundation's visible interests (conservation, education, cultural and health support), use the listed program contacts or the contact page to introduce the organization, and pursue warm introductions through mutual partners or intermediaries; recognize the foundation typically selects grantees rather than accepts open applications. Provide clear impact metrics and a succinct funding plan sized to the foundation's observed award range.
