Latest / The Newsletter Podcast with Fexingo: Substack, Beehiiv, and Email Newsletter Business / How Substack and Beehiiv Use Milestone Streaks
Transcript
- Lucas: So you've probably gotten a few of those celebratory emails from newsletters you follow — 'We hit 10,000 subscribers!' or 'One year of weekly posts!' They feel good to read, but there's actually a deliberate mechanism behind them called milestone streaks. Luna: Milestone streaks — like a digital pat on the back? Or is there more to it? Lucas: There's a lot more. Platforms like Substack and Beehiiv have built entire retention loops around them. The idea is simple: publicly track a consecutive action — weekly sends, subscriber milestones, writing streaks — and reward the writer with recognition, badges, or even financial incentives. Luna: It's basically gamification. I've seen it on Duolingo and Snapchat, but for newsletters? Lucas: Exactly. And it works. Let me give you a concrete case. A tech writer I follow on Substack — let's call him Alex — started a streak of sending a newsletter every single week. He hit the 52-week mark, and Substack sent him a congratulations email that he shared publicly. He told his readers, 'I've written every week for a year.' That simple announcement correlated with a 30% increase in paid conversions over the next month. Luna: Thirty percent? That's huge. Was it just the streak itself or the social proof of the announcement? Lucas: Probably both. The streak gave him credibility — 'This person is consistent, they're serious.' And Substack's celebration email acted as social proof: 'The platform recognises this milestone, so it must be valuable.' Beehiiv does something similar with built-in streak badges that writers can display on their profile pages. Luna: Right, I've seen those. A little fire emoji next to the writer's name for a 10-week streak. It's like a badge of honour. Lucas: Exactly. And the psychology behind it is well-documented. The 'streak effect' — once you've started a streak, you're more motivated to keep it going. For writers, that means fewer missed weeks, more consistent output. For subscribers, it signals reliability. That reliability translates into willingness to pay. Luna: But there's a flip side, right? Burnout. I've seen writers who feel trapped by their streaks, like they can't take a vacation without breaking the chain. Lucas: That's real. And it's a tension the platforms are still figuring out. Substack's streak feature is optional — you can choose to track it or not. But once you opt in, the social pressure builds. Some writers have admitted to publishing lower-quality content just to keep the streak alive. Luna: So the platform benefits from writer consistency, but the writer might suffer. That's a classic gamification problem. Lucas: It is. And that's why I think the best use of milestone streaks is as an internal motivation tool, not an external obligation. If you're a writer, use the streak to keep yourself accountable, but don't let it dictate your schedule to the point of burnout. And if you're a subscriber, recognise that a long streak doesn't guarantee quality — but it does correlate with commitment. Luna: I want to zoom in on the paid conversion angle. Why does a streak make people more likely to pay? Is it just the credibility, or is there something deeper? Lucas: I think part of it is the 'endowment effect' — subscribers who've been reading for free for 20 weeks feel like they've built a relationship. They've invested time. When the writer hits a milestone, it creates a natural moment to reciprocate: 'I've been reading for free all year, maybe it's time to support.' The streak acts as a reminder of that shared history. Luna: That makes sense. It's like a nudge. 'You've been here for 52 weeks — why not make it official?' Lucas: Exactly. And Beehiiv has taken it a step further with automated milestone emails. When a writer hits 100, 500, or 1,000 subscribers, the platform sends a celebration email to the writer, and they can share it with their list. That creates a virtuous cycle — the writer feels validated, the subscribers feel part of a growing community, and the platform gets more engagement. Luna: It's almost like a mini IPO for the newsletter. 'We've reached this many subscribers — celebrate with us.' Lucas: Yeah, that's a good way to put it. And the data backs it up. According to a 2025 study by the Newsletter Economics Lab, newsletters that publicly celebrate milestones see a 15 to 20 percent higher subscriber retention rate over the following six months compared to those that don't. Luna: So it's not just fluff — it actually moves the needle. Lucas: It does. But I want to be careful not to overhype it. The same study found that the effect diminishes after the first few milestones. The biggest retention boost comes from the first 100 subscribers and the first year of weekly sends. After that, each milestone has a smaller impact. Luna: So the novelty wears off. That makes sense. It's like the first time you get a birthday cake is special, but by the tenth time, it's routine. Lucas: Right. So the smart play is to use milestones strategically — don't celebrate every single one. Pick the ones that genuinely matter: the first 100, the first year, the 10,000th subscriber. Those are the moments that feel authentic and worth sharing. Luna: I also wonder about the dark side of streaks beyond burnout. Is there any risk of writers gaming the system? Like, buying subscribers to hit a milestone faster? Lucas: There's always that risk. Substack and Beehiiv have gotten better at detecting fake subscribers, but it's still an arms race. The platforms have an incentive to keep the streak metrics honest because if they become meaningless, the whole mechanism collapses. Luna: So integrity of the streak is key. One bad actor can ruin it for everyone. Lucas: Exactly. And that's why I think the most durable use of streaks is for internal motivation, not external validation. If you're a writer, track your own streak privately. Use it to keep yourself showing up. But don't hinge your self-worth on a public badge. Luna: That's good advice. And speaking of showing up, if this conversation has sparked something you've actually used or thought about, you know what keeps these episodes ad-free and independent — it's listener support. Lucas: Yeah, exactly. If you found today useful, consider buying us a coffee at buy me a coffee dot com slash fexingo. That support goes directly into research, editing, and keeping the podcast free for everyone. Luna: It's a small thing that makes a big difference. And we genuinely appreciate it. Lucas: Alright, back to the topic. So where do we see this going? I think in the next year or so, we'll see more platforms integrate streaks with actual financial rewards. Imagine Beehiiv giving a writer a bonus for hitting a 52-week streak, or Substack offering a reduced fee for consistent publishers. Luna: That would be a game changer. Turn a psychological trick into a tangible incentive. Lucas: And it would align the platform's interest — retaining writers — with the writer's interest — getting paid. Right now, the streak is mostly symbolic. Making it financial would create a much stronger loyalty loop. Luna: Speaking of loyalty, I want to ask about the subscriber side. Do you think streaks could be used to retain readers too? Like, 'You've opened every email for 10 weeks — here's a badge.' Lucas: I've actually seen some newsletters experiment with that. One writer I know sends a 'Reader of the Month' award to the subscriber with the longest open streak. It's a small gesture, but it creates a personal connection. And the subscriber feels seen. Lucas: Exactly. And that kind of mutual commitment is what builds a community, not just an audience. It's what separates a transactional newsletter from a relational one. Luna: So the takeaway here: use milestones and streaks strategically, keep them honest, and don't let them become a source of stress. They're tools, not traps. Lucas: Well said. And if you're a writer listening, I'd challenge you to pick one milestone to aim for this quarter. Maybe it's 10 consecutive weekly sends, or hitting 500 subscribers. And when you get there, celebrate it sincerely with your readers. Luna: I think that's a solid actionable. For me, the key insight was that the 52-week streak boosted paid conversions by 30% — that's worth a try. Lucas: Absolutely. And as always, we'll keep tracking what actually works. Next episode, we're looking at how newsletters use video snippets to increase click-through rates. See you then. Luna: See you.
