A paid subscription newsletter only works once free readers already trust you enough to pre-pay for more, so the real first question isn't which platform to use, it's whether you've earned that trust yet.
Before building a paid subscription newsletter, I'd want to see three things already in place: a free list of at least a few hundred genuinely engaged readers, a consistent publishing habit measured in months not weeks, and a clear reason someone would pay for more of you specifically rather than reading something free elsewhere. Skipping straight to a paywall without those tends to produce a launch with a lot of initial sign-ups from goodwill and then a quiet plateau.
The newsletters that do well with paid subscriptions usually have something narrow and specific: deep analysis in one industry, ongoing access to the writer, or information readers can't easily get elsewhere. General advice, however well written, is a harder sell as a subscription.
Most successful paid newsletters keep the free tier genuinely useful rather than a teaser, because the free edition is what earns trust and gets shared, and a free tier that feels deliberately withheld tends to slow growth at the exact stage you need it fastest. A common structure is a full free weekly issue plus a deeper paid edition, or free content for everyone with paid extras like community access, archives, or direct Q&A.
I'd think about the split in terms of what's timely versus what's durable. Timely commentary, quick takes, and roundups tend to work fine as free content because their value fades fast anyway, while durable material, deep frameworks, ongoing access, or anything a reader would want to come back to months later, is what people are actually willing to keep paying for. If you're not sure where to draw the line, look at which past issues got the most replies or shares, since that's usually where the paid content should live too, just deeper.
Most paid newsletters land somewhere in a monthly range that feels closer to a streaming subscription than a course, though niche B2B and finance newsletters can charge meaningfully more given how directly the content ties to someone's income. Annual pricing at a discount usually improves cash flow and retention at once, since a reader who pays annually is less likely to churn on a slow week.
Resist the urge to price low just because it feels safer. A price that's too low signals the content isn't worth much, and it also means you need a lot more paying subscribers to make the whole thing worthwhile, which puts more pressure on volume than most solo writers can sustain. It's usually easier to start slightly higher than feels comfortable and offer occasional discounts than to raise prices later on people who joined at a bargain rate.
Substack and beehiiv are the two most common starting points, and the right one depends less on features and more on how you plan to grow, since beehiiv leans toward tools built for scaling an audience while Substack leans toward a built-in discovery network. I've laid out the actual differences in Substack vs beehiiv for monetization and a broader platform comparison in beehiiv vs Substack.
Conversion usually happens over a series of touches rather than a single pitch: a strong welcome sequence that proves value early (see high converting welcome email sequence), the occasional free issue that hints at what paid subscribers get, and a clear, low-friction upgrade link in every email. Expect a modest single-digit percentage of an engaged free list to convert over time, not a flood on day one.
Retention for a paid newsletter comes down to one simple thing: did the subscriber actually see the issue they're paying for. If your paid edition starts landing in Promotions or gets caught by a spam filter after a platform migration, you'll see cancellations that look like a content problem but are really a delivery problem, and by the time you notice the pattern in your churn numbers you've usually lost a chunk of revenue already. It's worth treating deliverability as part of the product, and Unbury exists specifically for creators who've hit this wall after their list stops seeing emails they're paying for.
There's no universal number, but a few hundred genuinely engaged free readers is a reasonable floor. Fewer than that and you likely won't have enough volume to see meaningful paid conversions.
Price based on the specificity and income relevance of your content rather than a generic benchmark. A general interest newsletter and a niche financial one can reasonably charge very different amounts for the same subscriber count.
It depends on whether you're relying more on Substack's discovery network or building your own growth engine, where beehiiv's tooling tends to fit better. I compare the two directly in a separate guide.
