Latest / The Newsletter Podcast with Fexingo: Substack, Beehiiv, and Email Newsletter Business / How Newsletters Are Using Acquisition Sponsorships
Transcript
- Lucas: So there's this revenue model in newsletters that almost nobody talks about, but it's quietly becoming one of the smartest ways to monetize without burning reader trust. It's called acquisition sponsorship. Luna: Acquisition sponsorship. I've heard the term, but I'm not sure I've seen it in the wild. How is it different from a normal sponsor? Lucas: Right, so a normal sponsor—what most newsletters do—is a flat fee. You pay a thousand dollars, I run your ad to my 50,000 subscribers. You get impressions, maybe some clicks, but you're paying for reach, not results. Lucas: Acquisition sponsorship flips that. The sponsor pays per new subscriber you bring them. So if I have a newsletter and I run an ad for a course platform, the platform pays me, say, five dollars for every person who clicks through and signs up for their free trial. Not for sending the email—only for confirmed acquisitions. Luna: So it's performance-based. The sponsor only pays when they get a real lead. That's a lot less risky for them. But is it good for the newsletter operator? Lucas: It can be, if you have a responsive audience. The classic example is The Browser. You know that daily link newsletter? Curates five interesting articles every morning. Around 2023, they did a deal with an online learning platform—I think it was Skillshare, but the model is what matters. Lucas: The Browser had about 100,000 subscribers at the time. They ran sponsored placements in their daily email. Instead of charging a flat CPM, they negotiated a cost per acquisition. Each new free trial signup was worth, I believe, around six dollars. Over six months, they brought in 12,000 new subscribers for the sponsor. Luna: That's 12,000 new users. At six dollars each, that's 72,000 dollars in sponsorship revenue. Not bad for a newsletter that size. Lucas: Exactly. And here's the kicker—the sponsor didn't have to guess whether the ad would work. They knew exactly what they were paying for. The Browser, in turn, had a strong incentive to make the ad compelling, because if nobody clicked, they didn't get paid. Luna: So the newsletter operator becomes almost like an affiliate. But isn't there a risk of pushing too hard? Like, if you're only paid per acquisition, you might start writing ad copy that's too salesy and hurts your credibility. Lucas: That's the tension. But the smart operators handle it by being transparent. The Browser, for example, always framed the sponsor as a recommendation. 'We've been using this platform, we think you'll like it.' It wasn't a hard sell. And because their audience trusts them, the conversion rate was high enough to make the economics work. Lucas: Let me give you the math on why this matters. Typical newsletter CPM—cost per thousand impressions—for a business newsletter runs anywhere from 20 to 50 dollars. So if you have 50,000 subscribers and you charge a 40-dollar CPM, a single email sponsorship is 2,000 dollars. Luna: But with acquisition sponsorship, you could earn more if your audience converts. Or less, if they don't. Lucas: Right. So it's variable. But for a newsletter with a strong conversion rate—say 2 percent click-through and 10 percent of those sign up—you're looking at 100 conversions from a 50,000-person send. At five dollars per acquisition, that's 500 dollars. Less than the flat fee. But if you have a highly engaged audience, say 5 percent click and 20 percent convert, that's 500 acquisitions at five dollars—2,500 dollars. Better than the flat fee. Luna: So it rewards newsletters with high engagement, not just big lists. That's actually a healthier incentive for the creator, right? Instead of chasing subscriber count, you focus on building a responsive readership. Lucas: Exactly. And that's why platforms like Beehiiv and Substack are starting to build tools to facilitate this. Beehiiv has a feature called 'sponsorships' where you can set up cost per acquisition deals. They handle the tracking, so the newsletter operator doesn't need to build their own affiliate system. Luna: I've seen some Substack writers do this manually. They'll partner with a tool like ConvertKit or a course platform and just include a unique link. But it's clunky without native tracking. Lucas: Yeah, it's definitely easier when the platform handles attribution. But even without it, a lot of newsletter operators are moving toward performance-based deals because advertisers are demanding more accountability. The era of 'just run my ad and hope for the best' is fading. Lucas: And this isn't just for big newsletters. I've seen operators with lists of 5,000 run acquisition sponsorships with local software companies. They charge, say, three dollars per trial signup. If they send two sponsored emails a month and get 30 signups each, that's 180 dollars a month. Not life-changing, but it's a start. Luna: That's a nice supplementary revenue stream. But I want to dig into the trust angle. If a newsletter runs too many acquisition sponsorships, doesn't it start to feel like a sales funnel? Lucas: It can. That's why the best practice is to only promote products you actually use. And to cap the frequency. The Browser runs maybe one sponsored email per week, and it's clearly labeled. They also mix in unpaid recommendations. So the ratio of value to promotion stays healthy. Lucas: There's also a variant where the newsletter operator doesn't just take the money—they negotiate a discount for their readers. So the sponsor pays per acquisition, but the reader gets a deal. That triple win—reader saves money, sponsor gets a customer, newsletter gets paid—is the ideal. Luna: I like that. It aligns everyone's incentives. The reader feels like they're getting a perk, not an ad. Lucas: Exactly. And the newsletter operator can use that as a selling point when pitching sponsors. 'My audience is highly engaged, and I can offer you a cost per acquisition model that guarantees you only pay for results. Plus, I'll offer a discount code so your conversion rate is higher.' That's a compelling pitch. Luna: So if I'm a newsletter operator listening to this, how do I start? What's the first step? Lucas: First, know your numbers. What's your typical click-through rate on a sponsor link? What's your conversion rate? If you don't have that data, run a test with a simple affiliate link. See how many people click and how many convert. Then approach a sponsor with a proposed CPA. Lucas: Second, find sponsors whose product genuinely fits your audience. If you run a newsletter about productivity tools, partner with a task management app. Don't promote crypto exchanges to a list of librarians. Luna: Makes sense. And you'd want to start with a lower CPA to prove the model, then negotiate up as you show results. Lucas: Exactly. You can even offer a trial period: 'Let's run a month at four dollars per acquisition. If we hit 100 acquisitions, we renegotiate.' That builds trust with the sponsor and gives you data to show future partners. Lucas: One more thing—don't underestimate the value of a good landing page. If your sponsor's signup page is confusing, your conversion rate will tank. Sometimes it's worth asking the sponsor to create a custom landing page for your audience. That alone can double conversion. Luna: So acquisition sponsorship really rewards the newsletter operator who thinks like a marketer, not just a writer. Lucas: That's exactly right. And it's a model that's only going to grow. As more newsletters mature, sponsors will demand performance. The ones who embrace CPA deals now will have a competitive advantage. Luna: I want to circle back to something you said earlier about the trust dynamic. If these marketing conversations have sparked something you've actually used in your own newsletter—or even just a shift in how you think about monetization—that's exactly why we do this show without ads. Lucas: Yeah, we deliberately don't run ads on these episodes. If you want to support that choice, the link is buy me a coffee dot com slash fexingo. It's a small way to keep this resource free for everyone. Luna: Totally. And it means we can talk about models like acquisition sponsorship without any hidden agenda. So back to the math—what's the ceiling? Could a newsletter earn more from CPA than from flat-fee sponsorships? Lucas: Potentially, yes. If you have a highly engaged niche audience, your per-subscriber value can be much higher. For example, a newsletter about SaaS tools for HR teams might have a small list, but each subscriber is a decision-maker. A sponsor might pay 20 dollars per demo request. If you send to 2,000 people and get 50 demos, that's 1,000 dollars from a single email. Compare that to a flat CPM of 40 dollars—that same email would earn only 80 dollars. Luna: So the ceiling is higher, but the floor is lower. It's a risk-reward tradeoff. Lucas: Right. And that's why many newsletters use a hybrid model. They have a few flat-fee sponsors that guarantee baseline revenue, and a few CPA deals that can spike their income. The best of both worlds. Lucas: I think we'll see more newsletters moving toward this hybrid approach. Especially as analytics get better and platforms build native CPA tools. It's just better for everyone involved. Luna: It also forces the newsletter operator to really know their audience. You can't just guess—you need data. And that data makes you a better writer and a better businessperson. Lucas: Exactly. So if you're running a newsletter, start tracking your clicks and conversions. Even a simple spreadsheet works. Then reach out to one sponsor and propose a test. You might be surprised how many say yes. Luna: Alright, I'm convinced. I'm going to look at my own newsletter's numbers today. Lucas: That's the spirit. And if you do, let us know how it goes. We might follow up in a future episode.
