How to write a sponsorship letter
Short, specific, and about their customers, not your needs.
Facts checked 11 Oct 2026 · by the AdSworn team
A good sponsorship letter is short and about the sponsor's customers: who reads your page, why they're the sponsor's buyers, what exactly you're offering, what it costs, and how to say yes. Attach proof, such as the page's traffic and the searches that bring its readers, and name one specific page rather than your whole site. Send it to the person who runs marketing, and follow up once.
The five parts of a sponsorship letter
- Who reads itOne line on the audience, with a number and its source: "2,400 people a month find this article on Google, read from Search Console."
- Why they're the sponsor's buyersThe searches that bring them. "They search 'best logo maker' and 'logo design cost'" tells a logo company everything.
- The offerOne placement, one page, one term: a sponsored post inside the article for 12 weeks.
- The priceA fixed number. "Let me know your budget" makes the sponsor do the work.
- How to say yesOne link or one reply. The fewer steps, the more yeses.
Template 1: a short sponsorship email
Subject: Your readers are on [page topic]. Hi [name], [number] people a month read my article on [topic], almost all from Google searches like "[search 1]" and "[search 2]" (figures from Search Console). They're choosing a [product type] right now. I'd like to recommend [their product] inside that article for 12 weeks, in my own words, labelled Sponsored: $[price]. Here's the page with its traffic: [link]. If it's a yes, you can book it there. [Your name]
Under 120 words. It names one page, proves the audience, makes one offer at one price, and gives one way to say yes.
Template 2: a sponsorship request letter
Dear [name], I run [site], which publishes [what it covers] for [who reads it]. Our article "[title]" was read [number] times in the last 4 weeks, mostly by people who found it searching Google for "[search]". We'd welcome [company] as its sponsor. What we offer: a recommendation inside the article, written with you and labelled Sponsored, for [term], at $[price]. You'll receive a report of every view and click. The page, its traffic and the booking link: [link]. Thank you for considering it. [Name, title, contact]
Proof beats adjectives
Sponsors get pitched constantly, and most pitches say "engaged audience" with nothing behind it. A number with a source stands out: page views from Google Analytics, or clicks from Google Search Console. The searches behind a page are the strongest proof, because they show what readers want.

Who to send it to, and when
- Businesses that already sponsor. A company that advertises in your niche has a budget and knows the format.
- The person who runs marketing, not a general inbox. On a small company, that's often the founder.
- One follow-up, about a week later, with one new fact. Then stop.
