Letter of inquiry template that gets responses

A letter of inquiry (LOI) has one job: convince a program officer to ask for a full proposal. That is it. It is not the place to make your whole case, and trying to cram your entire mission, budget, and theory of change into one page is the most common reason LOIs go nowhere. Here is a structure that gives a funder exactly what they need to decide, in the order they need it.

Why the order matters

Program officers read LOIs fast, often between meetings, often a stack of them in one sitting. If the ask and the fit are not obvious in the first two sentences, you have lost the read before you get to the part where you explain your program well. Lead with what you want and why you qualify. Save the story for after you have earned the attention.

The structure

Opening line: who you are and what you are asking for. One sentence. Organization name, mission in a phrase, and the dollar amount or range you are requesting. Something like: "[Organization] provides after-school tutoring to 200 low-income students in [city], and we are requesting $15,000 toward our 2026 program year." No warm-up paragraph before this.

Second paragraph: why this funder. Name something specific about the funder's own giving, not a generic compliment. If you pulled their 990 or looked at their recent grants on our foundation directory, reference an actual recipient or focus area that overlaps with your work. "We noticed your recent support for youth literacy programs in [region]" tells a reader you did your homework. A line that could be pasted into any letter to any funder tells them you didn't.

Third paragraph: the problem and your response to it. Two to three sentences on the need, backed by a number specific to your community if you have one, followed by what your program does about it. Skip the origin story of your organization here. Save that for the full proposal if they ask for one.

Fourth paragraph: what the money does. Be concrete about the request. "This grant would fund tutoring materials and stipends for 15 volunteer tutors" is fundable. "This grant would support our operations" is not, because it gives the reader nothing to picture.

Closing: outcomes and next step. One or two measurable outcomes you expect (students served, hours delivered, whatever you track), then a short close: you welcome the chance to submit a full proposal or answer questions. No plea, no over-thanking. Confidence reads better than gratitude in a business letter.

Signature block: name, title, contact information, and your EIN. Funders check registration status before they read past paragraph one, so make it easy to find.

What to leave out

• Your full budget. A one-line total is fine. A budget breakdown belongs in a full proposal, not a one-page letter.
• Every program you run. Name the one this grant funds. A letter that tries to represent your whole organization ends up representing none of it well.
• Attachments, unless asked for. Most funders state exactly what they want alongside an LOI, if anything. Sending unsolicited attachments signals you didn't read their guidelines.
• Hedging language. "We hope you might consider" and similar phrasing softens an ask that should be direct. State the amount and let the letter carry the confidence.

Length and format

One page. Font and margins a program officer could print without adjusting. If the funder's guidelines specify a format, word count, or portal, follow those exactly over this template. Funders that accept LOIs almost always publish their own preferences, and ignoring a stated format is an easy way to get an inquiry set aside before anyone reads the content.

Before you send it

Check that the funder accepts unsolicited inquiries and that your cause area matches theirs. Our causes directory groups funders by focus area, so you can confirm a foundation has a track record in your space before spending an evening on a letter. A well-written LOI to a funder with no history in your cause area is still a letter that gets no response, no matter how good the writing is.

If you are sending LOIs to more than a handful of foundations this cycle, keep track of who you contacted, when, and what they said. Deadlines, rolling cycles, and different formats for each funder add up fast once you pass three or four. The free Sponsor a Purpose CRM keeps that tracking in one place instead of a spreadsheet you have to remember to update.

And since a program officer who is intrigued by your letter will very likely visit your website next, it is worth a quick check on what they will see when they get there. Our free website grader scores yours in about a minute so you can fix anything obvious before your next batch of letters goes out.

A letter of inquiry is not the place to prove everything about your organization. It is the place to prove you are worth thirty more minutes of a program officer's time. Give them a clear ask, an obvious fit, and a specific picture of what the money does, and that is usually enough to get the door open.
