Sponsor a niche newsletter

What to do

1. Find the newsletters your users already read. Ask them directly in your welcome email or onboarding: “Which newsletters do you actually open?” Then search:
   • newsletter ad marketplaces such as Paved, Passionfroot and the Beehiiv ad network, filtered by your niche,
   • Google for “[niche] newsletter” and “[niche] weekly”,
   • Substack and Beehiiv search for your topic.
2. Start with small, cheap, focused newsletters. A 3,000-subscriber newsletter about exactly your users’ job often beats a 100,000-subscriber general tech newsletter at a fraction of the price. Many small newsletters do not list ad rates; email the writer and ask. They often sell slots for less than you expect.
3. Ask for the numbers before you pay. Subscriber count, typical open rate, typical click-through on past sponsor slots, and an example issue. If they will not share any numbers, move on.
4. Buy one issue, not a bundle. A pack of four issues at a discount is only a deal if the first one works. Test a single placement first, even at full price.
5. Write the ad with one clear call to action. One product, one benefit, one link. Write in the newsletter’s tone, as if the writer were recommending it:
   • first line: the problem, in the reader’s words,
   • second: what your product does about it, with a number if you have one,
   • last: one action, “Try it free” or “Get the template”, never three links.
6. Send clicks to a matching page, not your home page. A page that repeats the ad’s promise and has one signup button. A special offer for that newsletter’s readers (“[Newsletter] readers get two months free”) helps both conversion and tracking.
7. Use UTM links for every placement. ?utm_source=newslettername&utm_medium=newsletter&utm_campaign=issue-date. Also ask “How did you hear about us?” on signup, because some people see the ad and come back later by typing your URL.
8. Measure cost per signup and cost per active user. Divide what you paid by signups a week after the issue, and then by users who actually did something. Compare newsletters on that number, not on clicks.
9. Repeat only what works, then buy a bundle. If a newsletter’s cost per active user is acceptable, book a few more issues, ideally a couple of weeks apart. Drop the ones that did not work after one try, unless you have a strong reason to test a new ad.

Template

A sponsor slot that fits most newsletters:

Sponsored: [Product] Still copying numbers from [tool] into client reports every Friday? [Product] builds the report automatically and sends it to your client. Most users set it up in under ten minutes. [Newsletter] readers get two months free: [link with UTM]

Why it works

Readers trust the newsletters they chose to subscribe to, and a small niche newsletter has an audience made almost entirely of your target users. You pay only for a placement in front of the right people, and a single test issue tells you quickly whether that audience wants what you built.

How it gets users

Results vary a lot between newsletters, which is why you test one issue at a time. A good placement in a small, focused newsletter might bring anywhere from a handful to a few dozen signups; a poor fit brings almost none. Clicks usually come in the first two days after the issue goes out. Expect that some of your tests will not pay off and that one or two newsletters will be worth repeating. Keep a simple spreadsheet: newsletter, price, clicks, signups, active users, cost per active user.

Common mistakes

• Starting with the biggest, most expensive newsletter you can find.
• Buying a multi-issue bundle before testing one issue.
• An ad with several links and several messages.
• Sending clicks to your home page.
• No UTM links, so you cannot tell which newsletter worked.
• Judging by clicks instead of signups and active users.
