Letter of Inquiry

What is a letter of inquiry?

When you have a project that might appeal to a foundation, they usually specify the types of materials they prefer to receive. In many cases, the initial communication involves a concise letter of inquiry (LOI) spanning one to three pages, which numerous foundations accept throughout the year on a rolling basis. Alternatively, certain funders may require you to submit a preliminary letter of intent as part of their formal proposal request process, often referred to as a Request for Proposal (RFP).

Writing tips 

Letters of inquiry should be well-written, straightforward, and compelling. It’s important to conduct thorough research on the foundation’s mission and focus areas beforehand, ensuring that each letter is customized to align with the specific goals of the organization.

If you are considering submitting a letter of inquiry, feel free to reach out to our office. We can assist with tailoring the LOI to suit the foundation’s priorities, offer feedback on the content, and provide editing support before it is sent to the potential funder.

Format and style guide

Note: when you write a letter of inquiry, only include attachments if the funder asks for them. Figures and charts should be left out of the initial communications and can be included if you are invited to submit a full proposal.
