Picking a newsletter platform isn’t a small decision anymore. Whoever a creator chooses now, they’re choosing months, sometimes years, of building an audience on top of that platform’s specific tools, its specific paywall mechanics, and whatever growth patterns that platform happens to produce.
Get the choice wrong and the cost isn’t just a clunky dashboard. It’s an audience built on infrastructure that quietly works against the thing the creator actually wants, which is readers who eventually pay.
Migrating a list of any real size later, once a creator has actually noticed the platform isn’t converting the way they hoped, is its own slow, imperfect process, so the decision carries more weight up front than most people give it credit for.
What beehiiv actually publishes
In June 2026, beehiiv released its own State of Paid Newsletters report, built from first-party data across the thousands of paid publications running on its platform.
The headline number is blunt: the median newsletter on beehiiv converts 0.62 percent of free subscribers into paying ones. The spread above that median is enormous. Top-decile publications in categories like investing and economy pull conversion rates as high as 18 to 30 percent, while most niches sit closer to that sub-one-percent median.
beehiiv CEO Tyler Denk framed the broader growth trend behind those numbers this way: “Richer tools plus a more mature user base drove the explosion in subscription revenue growth.” beehiiv’s chief customer officer, Preeya Goenka, put a finer point on what actually moves a publication off that low median: “Paid isn’t just a paywall, it’s a product launch with value prop, pricing, offers, automations, nurture sequences.”
What Substack doesn’t
Substack, by contrast, has crossed five million paid subscriptions across its platform as of 2026, a figure the company has shared publicly.
What it hasn’t shared, in any report or disclosure available in 2026, is a comparable conversion rate: what share of the free readers on a typical Substack actually become paying ones. The handful of specific percentages floating around the internet attributed to Substack trace back to aggregator sites and unsourced “statistics” roundups, not to anything Substack itself has published or that a credible third party has independently verified.
That’s worth sitting with rather than glossing over. A creator comparing these two platforms in 2026 isn’t actually looking at two comparable numbers. They’re looking at one platform that has chosen, for whatever mix of confidence and marketing reasons, to publish granular conversion data down to the industry vertical, and one that hasn’t published anything close to it.
Why the asymmetry itself is the real story
It would be more satisfying to hand over two clean percentages and let a reader pick the higher one. But treating beehiiv’s self-reported 0.62 percent median as directly comparable to a Substack number that doesn’t actually exist would be its own kind of misleading, dressing up a one-sided data point as a head-to-head contest.
beehiiv has an obvious interest in telling a strong paid-newsletter growth story, since it competes directly for the same creators Substack already hosts, so even its own number deserves the same scrutiny a creator would apply to any vendor’s benchmark report.
What the two platforms do differ on, in ways that are independently documented rather than self-reported, is how they structure the free-to-paid conversion mechanism itself.
Substack tends to lean on mid-article paywalls that interrupt a piece partway through, which can convert aggressively but also frustrates free readers faster. beehiiv leans more on inline upgrade prompts inside otherwise-free issues, a gentler nudge that trades some immediate conversion pressure for a longer runway with the free list. Neither approach is simply better. They’re different bets on the same tradeoff, and which one fits depends entirely on what a specific newsletter is actually trying to build.
A broader lesson sits underneath these two specific platforms. Any vendor benchmark report, from any company selling a tool, is worth reading the same way: as a genuinely useful data point, and also as a document written by a party with a stake in the story it tells. beehiiv’s numbers are more specific and more useful than anything Substack has put out, which is worth crediting. That doesn’t make them neutral.
Where I’ve landed thinking about this for my own newsletter decisions
Content strategy is most of what I actually do for a living, across several very different properties, and platform choice is exactly the kind of decision that looks like a spreadsheet problem until you notice half the spreadsheet is missing real numbers for one of the two columns.
My honest takeaway isn’t “pick beehiiv because it publishes better data” or “avoid Substack because it doesn’t.” It’s that a platform’s willingness to publish its own weak points, alongside its strong ones, tells a creator something about how that company thinks about the relationship, separate from whichever platform’s mechanics happen to fit a given audience better.
Across the different properties I work on, the honest answer to “which platform converts best” has never been a single number anyway. It’s been a much slower process of watching what a specific audience actually does, then adjusting the offer instead of assuming the platform will do the work alone.
Even beehiiv’s own report closes on advice that has nothing to do with which logo sits on the dashboard, urging creators to test their own approach to pricing and value rather than copying a template. That holds regardless of which platform’s paywall a creator ends up using, and it’s a more honest starting point than chasing a clean percentage that, for at least one of these two platforms, simply isn’t public yet.
