Transcript

Lucas: So Luna, I was going through my inbox this morning, and it hit me — there are more curated newsletters now than ever. But here's the thing: most of them are free, run by big media companies, and they're basically just link dumps. Yet I found one operator who's pulling in around five thousand dollars a month with a niche daily digest, and he works maybe fifteen hours a week. Luna: Wait, five grand a month from a newsletter? That sounds like the dream, but also kind of rare. What's his secret? Lucas: That's exactly what I wanted to dig into. His name's not important, but his model is. He curates for a very specific audience — finance professionals who need to stay on top of regulatory changes. Not general business news, not crypto, not marketing. Just regulatory shifts affecting asset managers. That focus is everything. Luna: So he's not trying to compete with the big guys like Morning Brew. He's going narrow. How does that translate into five grand? Lucas: Right. He has about eleven thousand subscribers, and he charges sponsors a flat fee per issue. He sends it out five days a week, and his open rates sit around sixty-five percent. For that niche, that's high. Sponsors pay for that engagement, not just the raw number. He runs two sponsor slots per issue, and each slot goes for about two hundred fifty dollars. Do the math — that's two thousand five hundred a week, but he only sells about half the slots in a typical month. So realistically, five grand. Luna: Sixty-five percent open rate is wild. I've seen industry averages closer to twenty or twenty-five. How does he keep it that high? Lucas: Consistency and trust, but also a very disciplined editing process. He reads maybe forty to fifty sources a day, but he only includes five to seven links per issue. Every single one has a one-line annotation that tells you why you should care. He's not just forwarding headlines; he's adding context. And he never misses a day. That reliability is what makes people open it. Luna: That sounds like a lot of work for fifteen hours. How does he manage to read fifty sources and curate that fast? Lucas: That's where the tools come in. He uses a mix of RSS feeds, a bookmarking app, and a few automated filters to pre-sort the noise. He's not reading everything word for word. He scans for keywords, then spends his time on the ones that pass the filter. Plus he has templates for the layout, so the writing part is mostly just those annotations. He says the real work is the judgment, not the typing. Luna: So it's like a second job but condensed. What about the starting phase? I imagine it's pretty hard to get those first subscribers without a budget. Lucas: He started by posting his daily picks on LinkedIn for about six months. Just the links and his one-liners, no newsletter signup at first. He built a small following, and when he finally put up a signup link, a few hundred people came over. Then he used that audience to get his first sponsors, which funded a few simple ads on LinkedIn targeting the same niche. That's how he grew to eleven thousand over about two years. Luna: So the LinkedIn presence was basically his growth engine. Did he ever consider going viral or doing SEO or anything like that? Lucas: He told me he tried a couple of broader posts, but the ones that worked were always the regulatory deep dives. So he doubled down on that. The niche is a feature, not a limitation. When you're the go-to for one specific topic, people pass your newsletter around because it saves them hours. That's how he gets word of mouth growth without trying. Luna: That makes sense. But what about the wall of free alternatives? There are tons of free newsletters covering regulations. Why do people pay? I mean, they don't pay for the newsletter itself, right? Lucas: Right, the readers don't pay. The sponsors do. But the readers stick around because his curation is better than the free alternatives. He's not just aggregating; he's prioritizing. In a world where everyone's overwhelmed, being a filter is valuable. And that value keeps the open rates up, which keeps the sponsors happy. Luna: But is that sustainable? I mean, what if a big player decides to launch a free regulatory newsletter and crush him? Lucas: That's a real risk, and he's aware of it. But his edge is the trust he's built. Big players have to cover a lot of topics, so they can't go deep on every niche. He can. Plus, he's thinking about extending his model — maybe a premium tier with deeper analysis or a community forum. But he's careful not to scale too fast and ruin the intimate feel that makes it special. Luna: It's refreshing to hear someone think about that. So many side hustles just chase growth and end up losing what made them work. Lucas: Exactly. And that's actually a good segue to something I've been meaning to mention. You know how we keep this show ad-free? It's because a handful of listeners chip in monthly through buy me a coffee dot com slash fexingo. That's literally what funds making this many of these. It's not huge, but it keeps us going without sponsors. Luna: Yeah, I'm always grateful for that. It's a small but loyal group, and it makes a real difference. We don't have to chase ads, so we can focus on the stories that matter. Lucas: And that's the same principle our newsletter guy is using — putting the audience first. So back to him. He's actually thinking about adding a paid tier soon, but he's doing it in a slow, deliberate way. He says he'd rather have a hundred paying members who love it than a thousand who ignore it. Luna: That's a smart mindset. So for someone listening who wants to start a similar side hustle, what's the first step? Should they just pick a niche and start on LinkedIn? Lucas: Pretty much. But the niche has to be something you genuinely care about, because you'll be reading about it every day for years. And it helps if it's a niche where people have money — like finance, law, or healthcare. Those audiences are attractive to sponsors, so the revenue potential is higher. Luna: So it's not just about passion, but also about the economics of the audience. What about the time to first revenue? How long did it take him to see his first sponsor deal? Lucas: About eight months. He had around two thousand subscribers by then, and he reached out to a few small companies that sold software to asset managers. He offered a discounted trial rate — like a hundred dollars for one issue — just to get testimonials. That first deal was more about proof than profit. Luna: And then he raised prices as the list grew. That's a classic playbook. But what about the tools? Any specific ones he recommends? Lucas: He uses a simple email service provider, nothing fancy. For curation, he swears by Feedly for RSS and a browser extension that lets him save articles with a click. He also uses a scheduling tool to prep a week's worth of intros in advance, so he only has to update the links daily. That's how he keeps it to fifteen hours. Luna: I love that he's so systemized. It shows that consistency doesn't have to mean burnout. So what's the biggest mistake people make when they try to start a newsletter side hustle? Lucas: They pick a topic that's too broad, like 'business news' or 'tech updates'. That's a losing game because you're competing with everyone. The other mistake is treating it like a blog — writing long essays instead of short, scannable annotations. His readers want the equivalent of a smart friend sending them the five best links of the day, not a think piece. Luna: So the curation is the product, not the writing. And the writing is just the glue. That's a helpful distinction. Lucas: Exactly. And one more thing — he's ruthless about his unsubscribe rate. If he sees a spike, he'll audit his recent issues to figure out what didn't resonate. He'd rather lose a hundred subscribers who don't care than keep them and drag his open rate down. That discipline keeps his sponsor rates high. Luna: So it's a constant feedback loop. That's a lot of data to watch. Does he have any analytics setup beyond the basics? Lucas: He tracks open rate, click rate, and which links get the most clicks. He also does a quarterly survey to ask readers what they want more of. That's how he pivoted from including ten links to five — because readers said they were overwhelmed. He listened, and his open rate went up. Luna: It's almost like a product manager, but for a newsletter. So what's the endgame for him? Is he planning to keep this as a side hustle forever, or is there a bigger vision? Lucas: He's open to both. Right now, the five grand a month is nice, but he's exploring a premium tier that could push it to eight or ten. And he's had a couple of acquisition offers, but he's not in a rush. He likes the autonomy and the extra income without the pressure of a full-time startup. Luna: That's a nice position to be in. So for our listeners who want to try this, what's one concrete thing they should do this week? Lucas: Spend an hour defining your niche as narrowly as possible. Write a sentence like 'I curate the most important regulatory changes for asset managers' or 'I find the best productivity tools for solo lawyers'. If you can't say it in one sentence, it's too broad. Then set up a free account on an email platform and start writing five annotations a day, even if you don't send them yet. Build the habit first. Luna: That's practical. And it doesn't cost anything but time. But how do you know if you've got the right niche? Like, what if you pick something and it turns out nobody cares? Lucas: That's the risk, but you can test it with a landing page and a few LinkedIn posts before you commit. If you write five posts about the topic and you get zero engagement, that's a signal. But it can also take a few tries. He actually tried two other niches before landing on regulatory compliance. He says failure is just data. Luna: So it's about persistence and iteration. I think that's a good note to end on. Lucas, any final thoughts? Lucas: Just that the newsletter space isn't dead — it's just that the generic ones are. There's always room for a sharp curator who respects people's time. And if you can do that, the money follows. Plus, you get to learn a ton about a field you care about. That's a win even if the revenue takes time. Luna: And that's what we're all about here — real side hustles, real numbers, real strategies. Thanks for joining us, and we'll catch you next time.
