Latest / The Newsletter Podcast with Fexingo: Substack, Beehiiv, and Email Newsletter Business / How Newsletters Use Productized Sponsorships to Scale Revenue
Transcript
- Lucas: There's this moment every newsletter operator hits — the one where a brand emails you out of the blue and says 'we'd love to sponsor your next issue.' Feels great, right? Then you have to figure out what to charge, what to promise, and how to do it again next month without starting from scratch each time. Luna: Yeah, the 'one-off deal' dance. I've talked to creators who spend more time negotiating a single sponsorship than writing the actual newsletter that week. Lucas: Exactly. And that's why a growing number of newsletter operators are moving toward what I'll call productized sponsorships — a standardized menu of ad products with fixed pricing, clear deliverables, and automated booking. Think of it as turning your newsletter into a media kit that runs itself. Luna: So less haggling, more selling. Who's doing this well? Lucas: One of the earliest and most famous examples is The Hustle, back before HubSpot acquired it. They didn't just sell 'a sponsored slot.' They had a tiered system — a 'Presented By' slot at the top, a mid-issue mention, a dedicated sponsored deep dive. Each had a fixed price, a guaranteed open rate benchmark, and a standard creative format. The advertiser picked a tier, paid the price, and the team executed. Luna: Right, and that predictability works both ways. The advertiser knows exactly what they're getting, and the newsletter team doesn't have to reinvent the wheel every time. Lucas: Exactly. And today, platforms like Beehiiv have baked this into their product. Beehiiv's ad network lets newsletter creators set floor rates, specify audience criteria, and then have advertisers bid or buy directly. The creator doesn't negotiate — they just approve or reject. It's a marketplace, not a sales process. Luna: And that scales. If you're a solo creator writing a weekly newsletter, you don't have time for back and forth emails with six different brand managers. Lucas: Precisely. So the core idea here is to package your audience into repeatable, predictable ad products. And the numbers matter. A newsletter with 50,000 subscribers in a niche like B2B SaaS can charge anywhere from 5,000 to 20,000 dollars per sponsored issue, depending on engagement metrics. Luna: That's a wide range. What determines where you land in that band? Lucas: A few things. First, open rate — a 40 percent open rate is worth more than 25 percent, obviously. Second, click-through rate on sponsored content — if your audience actually clicks, you command a premium. Third, audience quality — are your subscribers decision-makers in a high-value industry? A newsletter read by startup founders is worth more per subscriber than a general interest list. Luna: So productized sponsorship means you're essentially selling access to a specific, verified audience segment. The product is the audience, not the email. Lucas: That's exactly right. And the smartest operators build tiers that match different advertiser budgets. A 'Founding Sponsor' tier at 20,000 dollars per quarter includes a dedicated issue, a logo in every newsletter, and a social media shoutout. A 'Standard Sponsor' at 2,000 dollars per issue gets a text mention and a button. You want options for the startup with a five-figure budget and the enterprise with a six-figure one. Luna: And this is where it gets interesting — because once you have tiers, you can start thinking about inventory. How many sponsored slots do you sell per issue? Too many and you annoy readers. Lucas: Right. The Hustle was famously disciplined — they capped sponsorships at one per issue, maybe two if one was a 'Presented By' and the other was a small mention. They knew that reader trust is the asset, and you can't monetize trust into dust. If every issue has three ads, readers start tuning out. Luna: Yeah, I've unsubscribed from newsletters that felt like they were selling more than they were informing. The ratio has to stay in the reader's favor. Lucas: Which brings me to a counterintuitive point: sometimes the best way to scale sponsorship revenue is to sell fewer, higher-quality sponsorships. A single 'Presented By' deal worth ten thousand dollars per issue can feel cleaner than five two-thousand-dollar spots. Less clutter, more impact for the advertiser, better experience for the reader. Luna: And the advertiser pays a premium for that exclusivity. Everyone wins. Lucas: If this conversation has given you a concrete idea or two — maybe you're thinking about your own newsletter's sponsorship tiers — that's exactly what we hope for. And the way these episodes stay ad-free, by the way, is through listener support. If today's topic was useful to you, you can head over to buy me a coffee dot com slash fexingo to help us keep going. Luna: Yeah, it's a small gesture that makes a big difference. We put a lot of research into each episode, and knowing it helps someone makes it worth it. Lucas: Alright, back to the economics. So once you have your tiers and your inventory cap, the next question is how to price them. Many creators default to cost per thousand impressions, or CPM, which is standard in display advertising. But newsletters aren't display ads. Luna: Right, because a newsletter sponsor gets placement in a trusted voice, in an intimate channel — email inbox. That's worth more than a banner ad on a website. Lucas: Exactly. So savvy newsletter operators use a metric called effective CPM, or eCPM, that accounts for engagement. If your newsletter has 50,000 subscribers, a 40 percent open rate means 20,000 opens. If you charge 5,000 dollars for a sponsorship, your eCPM is 250 dollars per thousand opens. Compare that to a typical display ad CPM of 5 to 10 dollars. The premium reflects the trust and attention. Luna: And that premium is exactly what productized sponsorships capture. You're not selling impressions — you're selling attention from a curated audience. Lucas: Now, one risk with productized sponsorships is that they can feel impersonal if you're not careful. Some advertisers want a custom integration, not a tier. So the best approach is to offer a 'Custom' option alongside your tiers — priced higher, of course — that lets the brand collaborate on something unique. Luna: So you have a menu, but you also have a 'chef's special' for the big spenders. Lucas: Exactly. And that chef's special might be a sponsored research report, a co-branded survey, or a dedicated webinar. Those command even higher rates because they require more work but also deliver more value. Some newsletters generate 40 to 50 percent of their total sponsorship revenue from just two or three custom deals per quarter. Luna: That's a useful data point. So the productized tier handles the mid-funnel — consistent, lower-touch revenue — and the custom deals handle the top end. Lucas: Right. And the key is to automate the productized tier as much as possible. Beehiiv's ad network does this: you set your rates, your minimum audience size, your preferred categories, and then sponsors can book directly through the platform. You get an email: 'New sponsorship request from X brand.' You approve, and it's scheduled. Luna: And Substack is moving in that direction too, though they're more focused on paid subscriptions. But they do have a 'Recommendations' feature that functions a bit like an ad swap between newsletters. Lucas: Good point. Substack's model is more about cross-promotion than direct sponsorship, but it's still a productized exchange. The difference is that on Substack, the currency is audience access, not dollars. You recommend another newsletter to your subscribers, and they recommend yours. Luna: That's a barter system, which works great for growth but doesn't put cash in your pocket. So if you need revenue, you need the sponsorship model. Lucas: Exactly. And if you're on a platform like ConvertKit or Mailchimp, you can build your own productized system using landing pages and a simple rate card. You don't need a fancy ad network. You just need a page that says 'Sponsor This Newsletter' with three tiers, pricing, and a 'Book Now' button that links to your calendar. Luna: That's essentially turning your newsletter into a media property. And I think that's the mental shift: you're not a writer who occasionally sells ads — you're a publisher with a productized ad inventory. Lucas: That's the frame. And once you have that frame, you can start thinking about more sophisticated moves — like creating a sponsorship packages for multiple newsletters. If you run a network of three newsletters in adjacent niches, you can sell a 'network package' that gives the advertiser placement in all three. That increases your average deal size significantly. Luna: Right, and that's what some of the bigger newsletter networks do — like Morning Brew's portfolio approach. But for a solo creator, even having one productized tier is a huge step up from the 'email me and we'll figure it out' approach. Lucas: And the final piece I'd highlight is measurement. If you're selling productized sponsorships, you need to deliver on the metrics you promised. If you guarantee 20,000 opens and a 2 percent click-through rate, you need to track that and report it to the advertiser. That builds trust and repeat business. Luna: So transparency is part of the product. Advertisers will pay a premium if they know exactly what they're getting and can see the results. Lucas: Exactly. So the takeaway: whether you're on Beehiiv, Substack, or your own platform, think about how you can standardize your sponsorship offering. Create tiers, set prices, automate booking, and measure results. You'll spend less time negotiating and more time creating — and your revenue will become more predictable. Luna: And your readers will thank you for keeping the sponsored content clean and relevant. It's a win all around. Lucas: Alright, that's the framework. Next episode, we'll look at how newsletters are using sponsored content to build recurring revenue — not just one-off deals, but ongoing partnerships. See you then.
