Latest / The Newsletter Podcast with Fexingo: Substack, Beehiiv, and Email Newsletter Business / Why Newsletters Are Hiring Full-Time Ad Sales Teams
Transcript
- Lucas: A newsletter with fifty thousand subscribers might earn between ten and twenty thousand dollars per sponsorship edition if they're working through a network. But what if that same writer could sell that same placement directly for closer to thirty thousand? Luna: That spread — that's the reason some of the biggest independent newsletters are now hiring full-time ad sales people. It's not just about offloading work anymore. Lucas: Exactly. In the past two years we've seen a real shift. The top tier of newsletter writers — the ones doing over half a million in annual revenue — are starting to look less like solo operators and more like boutique media companies. And a key part of that transformation is building an in-house sales function. Luna: So walk me through the math. What does a dedicated sales hire actually change? Lucas: Let me use a concrete example. There's a Substack writer — covers B2B SaaS, about seventy thousand subscribers, call it 'The Growth Stack' — who crossed five hundred thousand dollars in ad revenue last year. They did it by hiring one salesperson in early 2025. Luna: And before that they were using an ad network? Lucas: Right. They were on one of the bigger newsletter ad platforms. Typical CPM was around twenty-five dollars. A solo sponsorship went for about fifteen thousand. The network took a thirty percent cut, so net was around ten-five. Then they hired a sales rep on a base plus commission structure — seventy-five thousand base, ten percent commission on deals closed. Luna: So the bet is that the rep can sell at higher rates and keep more of the revenue. Lucas: And they did. The rep went out and sold custom packages — not just a single newsletter mention but what they called 'sponsorship series': three editions over a month, plus a dedicated email to the list, plus a mention in the weekly roundup. Average deal size jumped to thirty-five thousand. CPM effectively doubled because the packages were bundled and the rep could tell the story of why the audience was worth more. Luna: That's interesting. Because a network can't really tell that story — they're matching advertisers to newsletters algorithmically. Lucas: They can't. A network's pitch is scale and efficiency. A dedicated rep's pitch is specificity and relationship. And for certain advertisers — especially B2B SaaS companies with six-figure customer acquisition costs — that specificity is worth a premium. The rep can say, 'Look, fifty-eight percent of this audience are directors or above at companies with over two hundred employees. I can get you in front of them three times in a month.' Luna: So the sales rep isn't just selling placements. They're selling audience insight. Lucas: Exactly. The best ones become a bridge. They help the advertiser craft the offer, they advise on subject lines, they sometimes even suggest which topic the newsletter should cover to maximize click-through. That level of service is impossible to get from a network. Luna: But not every writer needs this. At what subscriber count does it start to make sense? Lucas: I'd say north of fifty thousand active subscribers, and only if the writer already has consistent sponsorship demand — meaning they're turning down advertisers at least a few times a month. If you're still prospecting for sponsors, a sales hire will be underutilized. The trigger is when you have more demand than you can personally handle, and you're leaving money on the table because you can't negotiate or bundle. Luna: That makes sense. The other thing I've seen is that some writers are hiring part-time or fractional sales directors instead of full-time reps. That seems like a lower-risk way to test the model. Lucas: Absolutely. A fractional sales director might cost two to three thousand a month, they work ten to fifteen hours a week, and they bring an existing roster of advertiser relationships. For a writer at forty thousand subscribers, that could be the perfect middle ground. I know one newsletter — covers consumer tech — that went fractional in late '24 and grew sponsorship revenue from eighty thousand to two hundred ten thousand in twelve months. The fractional person basically took over the whole sales process. Luna: And those relationships are sticky. If the advertiser has a good experience with one newsletter, they're more likely to come back for the next campaign. That builds recurring revenue. Lucas: Right. The economics compound. A rep who closes a deal in Q1 can resell that same advertiser in Q2 and Q3. The commission cost stays roughly the same, but the revenue grows as the advertiser increases spend. Over two years, that single hire can pay for itself many times over. Luna: There is a risk though. What if the rep leaves and takes the relationships with them? Lucas: It's a real concern. Smart writers mitigate it by keeping the advertiser relationship multi-threaded — the writer still does the intro calls, still hosts the sponsored content, still sends personal follow-ups. The rep manages the process but the writer remains the face. Also, non-solicit agreements are standard. And honestly, in this market, good sales reps know their value and tend to stay if the commission structure is fair. Luna: Let me shift slightly. What about the actual tools? Do these in-house teams use different tech than a network? Lucas: Yeah, it's a different stack. A network gives you a dashboard where advertisers self-serve. An in-house operation needs CRM — usually HubSpot or a lightweight tool like Pipedrive — plus a media kit builder, plus maybe an ad server like Adzerk if they're doing programmatic fill. The writer I mentioned earlier built a simple rate card in Canva and tracks deal stages in a shared Google Sheet. It doesn't have to be complex. Luna: And the advertiser gets more transparency too. They can see exactly when their campaign ran, what the open rate was, click-throughs. That builds trust. Lucas: It does. And it lets the writer charge a premium. I've seen direct-sold sponsorships go for two to three times the network CPM. The advertiser is paying for the relationship and the insight, not just the impression. Luna: If these marketing conversations have sparked something you've actually used — maybe a pricing tweak or a new outreach strategy — that's exactly the kind of practical takeaway we hope lands. And if you find yourself coming back to these episodes week after week, listener support is what keeps us ad-free and independent. If that's valuable, you can find us at buy me a coffee dot com slash fexingo. Easy to find, no pressure. Lucas: Appreciate that. Back to the topic — one thing I want to flag is that the trend isn't just at the top. I'm seeing newsletters with as few as fifteen thousand subscribers hire part-time sales help, especially if they have a niche that commands high CPMs. Think finance, healthcare, or legal audiences. A finance newsletter with fifteen thousand subscribers can still charge a hundred dollars CPM because the audience is so targeted. Luna: Right, so the threshold isn't just about subscriber count — it's about revenue per subscriber. A high-value niche can justify a sales hire earlier. Lucas: Exactly. The math is simple: if a sales hire costs seventy-five thousand fully loaded, and they generate a hundred fifty thousand in incremental revenue that you wouldn't have gotten otherwise, that's a no-brainer. But you need to be confident in the demand. Luna: What about the writer's time? A lot of these newsletter operators are still writing every edition themselves. Doesn't sales management distract from that? Lucas: It can, but the goal is the opposite. The writer should be freed up to focus on content. A good sales rep handles the negotiation, the scheduling, the reporting. The writer only needs to show up for the actual content and maybe a brief call with the advertiser to align on messaging. It's a leverage play. Luna: So we're seeing the maturation of the newsletter as a media business. From solo writer, to writer plus ad network, to writer plus dedicated sales. What's next? Lucas: I think the next phase is writers hiring multiple salespeople — one for different verticals or regions — and eventually building a full ad operations team. Some of the biggest newsletters in tech are already there. They have a sales director, an account manager, and a coordinator. That's a six-figure payroll, but they're doing millions in ad revenue. Luna: So the newsletter industry is quietly building its own version of a media agency. Just inside a single publication. Lucas: Exactly. And that's a fascinating development. Five years ago a newsletter was a side project. Now it's a company with a sales meeting on Thursday. Luna: And for the writers watching from the middle tier — the ones at twenty to thirty thousand subscribers — the lesson might be to start thinking about who could sell for you, even if it's just a few hours a week. Lucas: That's the takeaway. You don't need to hire tomorrow. But start tracking how many inbound sponsorship requests you're turning down. If that number is more than one or two a month, it's worth exploring a fractional or part-time arrangement. The revenue lift can transform the economics of your entire operation.
