What Is a Letter of Inquiry?
A Letter of Inquiry (LOI) — sometimes called a Letter of Intent — is a brief document (typically 2–4 pages) that introduces your organization and project concept to a funder before they invite a full proposal. Many private foundations and some government agencies use LOIs as a screening mechanism to manage their application volume.
Treat It Like a Mini-Proposal
An LOI is not a casual letter. It should include: a concise problem statement, your proposed intervention, your target population, expected outcomes, total funding request, and your organization's relevant qualifications. Think of it as a two-page version of your full proposal.
The Opening Paragraph Is Everything
Your first paragraph must immediately establish the problem, your solution, and your ask. Example: "We are seeking $150,000 to train 500 women smallholder farmers in climate-smart agriculture techniques across three districts of Malawi, reducing crop failure rates by 30% within two seasons."
Demonstrate Funder Alignment
Reference the funder's specific priorities. If the Ford Foundation has a focus on "reducing inequality," name that focus and explain how your work advances it. Funders want to see that you've done your homework.
Keep It Tight
Resist the urge to include everything. An LOI is a teaser, not a comprehensive report. Leave room for the full proposal. Your job here is to generate enough interest that they invite you to submit the complete application.
Follow Up Appropriately
If you haven't heard back within the stated timeframe, one polite follow-up email is appropriate. Keep it brief: "I wanted to confirm receipt of our LOI submitted on [date] and inquire whether there is any additional information we can provide."
