An email list is the one audience a solopreneur actually owns. Social platforms can throttle your reach or change the rules overnight; a newsletter goes straight to the inbox, every time, for free. And with the right platform, that list becomes a revenue stream — paid subscriptions, sponsorships, and product launches all run through it.
The catch is choosing where to build it. Newsletter platforms differ most on two things: how they help you grow, and how much they take when you start making money. AI features — subject-line testing, content suggestions, audience segmentation — now come baked into the better ones.
Here are the best newsletter platforms in 2026, and who each is for.
The best newsletter platforms for solopreneurs
Beehiiv — best for growing a newsletter into a business
Beehiiv was built by former newsletter operators, and it shows: it bundles growth tools (referral programs, recommendation networks, SEO-friendly web archives), a built-in ad network for sponsorships, and AI writing help. The free plan covers up to 2,500 subscribers with no feature gating, and paid plans start around $34/month as you scale, with 0% fees on paid subscriptions. It’s the strongest all-round pick if you’re serious about growth and monetization.
Kit — best for creators selling products
Kit (formerly ConvertKit) is built around creators who sell — courses, digital products, coaching. Its automation and tagging are excellent, and the Newsletter plan is free for up to 10,000 subscribers, with Creator plans from around $9/month and a small transaction fee on paid subscriptions. Choose it if your newsletter is the engine for selling things, not just publishing.
Substack — best for the simplest possible start
Substack is free to use and free to start a paid newsletter — but it takes a 10% cut of subscription revenue on top of payment processing. That’s a fine trade when you’re starting from zero and want zero setup, but the cut gets expensive as you grow. Best for writers who want to hit publish today and worry about economics later.
Ghost — best for owning your whole platform
Ghost is open-source: self-host it free, or use their managed hosting from around $9/month. It combines a newsletter, a full website, memberships, and 0% platform fees on paid subscriptions. The pick for the technically comfortable solopreneur who wants to own everything and avoid revenue-sharing entirely.
MailerLite — best budget all-rounder
MailerLite is a full email marketing tool that doubles as a newsletter platform, with a free plan up to 1,000 subscribers and paid plans from around $9/month. Strong automation and landing pages for the price. Good if you want classic email marketing features alongside your newsletter without a premium bill.
Flodesk — best for beautiful design
Flodesk makes every email look designed, with a flat pricing model that doesn’t scale with list size — appealing once your list gets large. Reach for it if visual polish matters to your brand and you’d rather not pay more just because your audience grew.
Which one should you choose?
For most solopreneurs building a newsletter as a real channel, start with Beehiiv — its free tier is generous and its growth tools are the best here. If selling products is the point, Kit. Want to publish instantly with no setup? Substack. Want to own the whole stack? Ghost. Tight budget with real automation needs? MailerLite. Design-obsessed? Flodesk.
A newsletter platform overlaps with, but isn’t the same as, broader email marketing. If you need heavy automation, sequences, and campaign tooling beyond publishing, compare with our guide to the best AI email marketing tools for solopreneurs — several tools here appear there too, framed around campaigns rather than publishing.
We test a new category of solo-business tools every week and send the winners to subscribers. You can see the format in action by joining The Solo Stack — built, fittingly, on Beehiiv.
Frequently asked questions
Which platform lets me keep the most subscription revenue?
Beehiiv and Ghost charge 0% platform fees on paid subscriptions, so you keep the most (minus payment processing). Substack’s 10% cut is the most expensive as you scale, though its zero-setup convenience can be worth it early on.
Can I start a newsletter for free?
Yes. Beehiiv (up to 2,500 subscribers), Kit (up to 10,000 on the Newsletter plan), MailerLite (up to 1,000), and Substack are all free to start. You can grow a real audience before paying anything.
What’s the difference between a newsletter platform and email marketing software?
Newsletter platforms optimize for publishing and audience growth — web archives, referral tools, subscriptions. Email marketing software optimizes for automation and campaigns — sequences, segmentation, sales flows. Tools like Kit and MailerLite straddle both, which is why they appear in both categories.
Can I move my list to another platform later?
Yes — you can export your subscriber list from any reputable platform and import it elsewhere. That portability is exactly why owning an email list beats renting a social audience. Migrating paid subscribers takes more care, so pick thoughtfully if you monetize.
Do I need the AI features?
They’re helpful, not essential. AI subject-line testing, content suggestions, and segmentation can lift open rates and save time, but a consistent, genuinely useful newsletter matters far more than any AI feature. Start writing; lean on the AI to refine.
