If your priority is “start free, build an audience, then turn on paid memberships without having to migrate,” I’d pick Kit.

My pick: Kit

Kit's current free Newsletter plan is unusually generous: up to 10,000 subscribers, unlimited email broadcasts, and it explicitly supports recurring subscriptions on the free plan. When someone starts paying, Kit charges 3.5% + $0.30 per transaction. kit.com

When I'd choose Substack instead

Choose Substack if you want the absolute simplest “newsletter → paid publication” experience and don't care much about marketing automation. Publishing is free regardless of subscriber count, and you can turn on monthly/annual paid plans later. The big downside is Substack's 10% cut of every paid transaction, on top of Stripe fees. support.substack.com

Substack

When I'd choose beehiiv

I'd choose beehiiv if you expect the newsletter to become a larger media/business operation. Its free Launch plan supports 2,500 subscribers and unlimited sends, while the Scale plan adds paid subscriptions with 0% platform take rate, plus automations, digital products, community, and other growth tools. www.beehiiv.com

beehiiv pricing

Bottom line:
Kit = best fit for your stated requirement.
Substack = easiest if paid publishing is the core product.
beehiiv = best if you're building a serious newsletter business.

If you tell me roughly how many subscribers you expect (e.g. 500, 5,000, 20,000) and whether the paid tier would be $5, $10, $20+, etc., I can tell you which one will cost you the least as you grow.

If your priority is “start free, build an audience, then turn on paid memberships without having to migrate,” I’d pick beehiiv.

My ranking

Why beehiiv: Its free Launch plan gives you up to 2,500 subscribers and unlimited sends. When you're ready to monetize, Scale adds paid subscriptions with a 0% platform take, plus growth tools such as referrals and an ad network. www.beehiiv.com

Why not automatically Substack? It's arguably the easiest place to start: free newsletters have no monthly fee and there is no subscriber limit. But once you charge, Substack takes 10% of paid-subscription revenue indefinitely, in addition to payment processing. newslettercalc.com

Kit is worth considering if you expect your newsletter to eventually sell courses, digital products, or use sophisticated email automation. Its free tier is particularly generous, but the paid plans become a monthly expense as your list grows. newslettercalc.com

My simple recommendation

• “I want to build a serious newsletter business” → beehiiv
• “I want the biggest possible free tier” → Kit
• “I just want to write and eventually put some posts behind a paywall” → Substack

One important wrinkle: if you expect to make substantial membership revenue, beehiiv's 0% platform fee becomes very attractive. For example, on $2,000/month in paid subscriptions, a 10% Substack cut is $200/month before payment processing. beehiiv instead has a fixed paid-plan cost once you move to Scale. www.beehiiv.comnewslettercalc.com

If you tell me roughly how many subscribers you expect in year 1 and what you'd charge for membership (e.g. $5/month), I can tell you which is cheapest and best for your specific situation.

If your main goal is “start free, build an audience, then turn on paid memberships without migrating later”, I’d narrow it to these:

www.beehiiv.com

My recommendation by scenario

Pick beehiiv if:

• You’re starting from zero.
• You expect to grow into a serious newsletter business.
• You may want sponsorships, referrals, analytics, segmentation, and paid subscriptions later.
• You don’t want to pay a percentage of membership revenue.

Its free plan supports up to 2,500 subscribers, and its paid tiers include paid subscriptions with no platform revenue share (payment processing still applies). www.beehiiv.com

Pick Substack if:

• You mainly want to write and hit “publish.”
• You value the chance of discovery inside Substack’s ecosystem.
• You’re unsure whether you’ll ever monetize.

The tradeoff: once you have paying subscribers, Substack’s revenue share can become expensive as income grows. tiergauge.com

Pick Ghost if:

• You want a newsletter + website + membership publication.
• You care about owning the brand and having more control over design and content. Ghost supports memberships and paid subscriptions without taking a cut of subscription revenue on its hosted plans, though you pay for hosting. ghost.org

My default choice:

Start with beehiiv unless you are specifically a writer who wants Substack’s simplicity or a publisher building a full website (then Ghost).

A good long-term path:

1. Start free.
2. Build your email list.
3. Add a paid tier when you have engaged readers.
4. Keep your subscriber list exportable so you’re not trapped.

If you tell me your newsletter type (personal writing, business, niche hobby, local news, paid research, creator brand, etc.) and expected size (100 / 1,000 / 10,000+ subscribers), I can narrow it further.

If your priority is “start free, build an audience, then turn on paid memberships without making the switch painful,” I’d narrow it to Substack vs. beehiiv vs. Kit.

My pick: Substack if simplicity is #1

Substack is probably the easiest path. Publishing and email distribution are free regardless of subscriber count, and you can later enable free, monthly, annual, and founding-member tiers. support.substack.com

The catch: once you turn on paid subscriptions, Substack takes 10% of subscription revenue, on top of payment-processing fees. support.substack.com

Pick beehiiv if you expect this to become a serious newsletter business

beehiiv gives you a free Launch plan up to 2,500 subscribers, with unlimited sends. Its paid Scale plan supports paid subscriptions with 0% platform take, so you keep your subscription revenue apart from Stripe fees. www.beehiiv.com

That's a big advantage if you eventually expect meaningful paid revenue. The tradeoff is that monetization requires moving to a paid beehiiv plan.

Pick Kit if you're a creator building more than a newsletter

Kit is particularly good if you want newsletters plus digital products, audience segmentation, automations, and recurring subscriptions. Its current free Newsletter plan supports up to 10,000 subscribers and unlimited broadcasts, and you can sell subscriptions from it. help.kit.com

Quick decision

For your exact wording, I'd choose Substack unless you already know you'll want sophisticated growth/marketing tools. It's the least complicated “free now → paid memberships later” path.

If you tell me roughly how many subscribers you expect in year 1 and whether the paid membership would be something like $5/month, $10/month, or higher, I can tell you which one is likely to cost you the least.

If your priority is “start free, build an audience, then turn on paid memberships without having to migrate,” I’d pick Kit.

1. Kit — my pick for you.
Kit just launched a free Newsletter plan for up to 10,000 subscribers, with unlimited email sends, landing pages, digital products, and subscriptions. You can start selling paid subscriptions directly from the free plan; Kit charges 3.5% + $0.30 per transaction for paid newsletter sales. help.kit.com

3. Substack — best if you want the absolute easiest setup.

Substack

What I'd do

If you're starting from zero, I'd choose Kit. Its new 10,000-subscriber free tier gives you a lot of runway, and you don't need to wait until you're paying for the platform before experimenting with memberships. kit.com

If your newsletter is primarily writing/opinion/news, I'd lean Substack for simplicity and its built-in reader ecosystem.

If you're building a media/business newsletter with sponsorships, growth tools, analytics, and monetization, I'd choose beehiiv.

If you tell me what the newsletter will be about and roughly how many subscribers you expect in year 1, I can give you a much more specific pick.

If your priority is “start free, build an audience, then turn on paid memberships without a painful migration,” I’d pick Kit for most creators.

My pick: Kit

Kit's free Newsletter plan currently supports up to 10,000 subscribers, unlimited email sends, landing pages/forms, segmentation, and—importantly—paid subscriptions. You can upgrade later without moving your audience. help.kit.com

That makes it particularly attractive if you're thinking:

“I don't want to pay anything until I know people actually want this, but I want the infrastructure for memberships already in place.”

Kit also lets you create monthly, quarterly, or annual paid newsletter subscriptions. help.kit.com

When I'd choose the others

Choose beehiiv if you expect the newsletter to become a serious media/growth business. Its free plan gives you up to 2,500 subscribers and unlimited sends; its Scale plan adds paid subscriptions with 0% platform take plus growth tools like recommendations, Boosts, ads, and automations. www.beehiiv.com

Choose Substack if your main goal is simply writing and getting readers with almost zero setup. Publishing is free regardless of subscriber count, and you can switch on monthly/annual paid subscriptions whenever you're ready. The catch is that Substack takes 10% of every paid transaction, indefinitely, on top of payment-processing fees. support.substack.com

Substack pricing information

Bottom line

• You want the best long-term creator platform → Kit
• You want aggressive newsletter growth/monetization → beehiiv
• You want the easiest possible “write → publish → charge readers” experience → Substack

For the specific thing you described, I'd start with Kit. It gives you a remarkably generous free runway and lets you introduce paid memberships later without changing platforms.

If your priority is “start free, build an audience, then turn on paid memberships without having to migrate”, I’d pick Kit.

My ranking

Why I’d choose Kit: its free Newsletter plan currently supports up to 10,000 subscribers, unlimited email sends, and subscriptions, so you can start without paying and don't need to rebuild your audience when you monetize. help.kit.com Its paid newsletter system supports recurring monthly/quarterly/annual subscriptions, and Kit says transaction fees are 3.5% + $0.30 per transaction. kit.com

Substack is the simplest if you want to essentially “write → publish → build subscribers → turn on paid.” Publishing is free regardless of subscriber count, but once you charge readers, Substack takes 10% of each paid transaction, on top of Stripe fees. support.substack.com That's a meaningful difference once you're making real money.

beehiiv is particularly attractive if you think your newsletter will become a larger media/growth business. Its free Launch plan goes to 2,500 subscribers, while the Scale plan includes 0% take rate on paid subscriptions along with advertising, automations, and other growth tools. www.beehiiv.com

The simple decision

• “I want the easiest path from free → paid and lots of creator/business tools.” → Kit
• “I mainly want to write and build a publication with minimal fuss.” → Substack
• “I want to aggressively grow a newsletter and monetize through multiple channels.” → beehiiv
• “I want my newsletter to be a full owned website/membership publication.” → Ghost

For your exact wording, I'd start with Kit. You can remain on the free plan while validating the newsletter, then introduce paid memberships when you have an audience—without changing platforms. help.kit.com

If your priority is “start free, then turn on paid memberships without having to migrate,” I’d pick Kit.

My ranking

Why Kit wins: its free Newsletter plan currently supports up to 10,000 active subscribers, unlimited email sends, and paid subscriptions. You can start selling paid memberships without first paying for the platform; Kit charges 3.5% + $0.30 per paid transaction on the free plan. help.kit.com

Kit

beehiiv is my second choice. Its free Launch plan gives you 2,500 subscribers and unlimited sends, and its paid-subscription system takes 0% platform revenue share (you still pay Stripe processing). The catch is that the monetization features require moving to a paid beehiiv plan, currently starting at $49/month. www.beehiiv.com

Substack is the simplest if you mainly want to write and don't care much about sophisticated email marketing. Publishing is free, and you can switch on paid subscriptions whenever you want. But Substack takes 10% of every paid transaction, on top of Stripe fees. support.substack.com

Substack

The short version

• Want maximum flexibility + free → paid: Kit
• Want newsletter growth, ads/sponsorships, and 0% platform fee on paid subs: beehiiv
• Want the easiest “writer starts free, readers become members” experience: Substack

For your exact wording, I'd start with Kit. It gives you a surprisingly generous free runway, and you don't need to rebuild your newsletter when you decide to monetize. help.kit.com

If you tell me roughly how many subscribers you expect in year 1 and whether it's a personal newsletter, business newsletter, or paid publication, I can tell you which one is likely to be cheapest and best long-term.

If your priority is “start free, then turn on paid memberships without having to migrate later,” I’d pick beehiiv.

My ranking

Why beehiiv: Its free Launch plan gives you up to 2,500 subscribers and unlimited email sends. When you're ready to monetize, its paid plan supports paid subscriptions with 0% platform take (you still pay Stripe processing). www.beehiiv.com

Kit is the strongest alternative if you expect your newsletter to eventually become a broader creator business. Its free plan currently supports up to 10,000 subscribers, unlimited broadcasts, and selling subscriptions/digital products. help.kit.com

Substack is the easiest if you primarily want to write. Publishing is free regardless of subscriber count, and turning on paid subscriptions is very straightforward. The tradeoff is that Substack takes 10% of every paid transaction, indefinitely, in addition to payment-processing fees. support.substack.com

What I'd choose

• Serious newsletter/business → beehiiv
• Creator + courses/products/memberships → Kit
• Writer/blogger who wants maximum simplicity → Substack

If you tell me roughly how many subscribers you expect (e.g. 500, 5,000, or 50,000) and what you'd charge for membership, I can calculate which one will cost you the least as you grow.

If your priority is “start free, build an audience, then turn on paid memberships without a painful migration,” I’d narrow it to Substack, Kit, and beehiiv.

My pick: Kit

Kit

It’s probably the best fit if you want to build a newsletter as a business, rather than primarily as a publication. Kit’s free Newsletter plan supports up to 10,000 subscribers, unlimited email sends, landing pages, and subscriptions. You can later sell recurring newsletter memberships directly through Kit. help.kit.com

The big advantage: you can start free and monetize without changing platforms. On the free plan, paid transactions currently carry a 3.5% + $0.30 fee; paid plans start at $39/month for up to 1,000 subscribers. kit.com

When I'd choose the others

Substack — simplest possible choice

Substack

Choose this if you mainly want to write and publish, with almost no technical setup. Publishing is free regardless of subscriber count, and you can switch on paid subscriptions whenever you're ready. The tradeoff is that Substack takes 10% of paid subscription revenue, plus payment-processing fees. support.substack.com

beehiiv — best if growth/monetization is the bigger ambition

beehiiv

Its free Launch plan currently supports 2,500 subscribers and unlimited sends. Paid subscriptions are a major part of the platform, with 0% platform revenue share on the Scale plan, though Scale currently starts at $43/month. www.beehiiv.com

Quick decision

For your exact wording, I'd pick Kit. It gives you a particularly generous free starting point while preserving a straightforward path to paid memberships later. help.kit.com

If you tell me roughly how many subscribers you expect in year 1 and whether you'll sell subscriptions only or also courses/products, I can tell you which of the three is likely to cost you the least.

If your priority is “start free, then turn on paid memberships without rebuilding everything,” I’d pick Kit.

My recommendation: Kit

• Free up to 10,000 subscribers on its Newsletter plan, with unlimited email sends. help.kit.com
• You can set up paid subscriptions even on the free plan, with Kit charging 3.5% + $0.30 per transaction when you earn revenue. kit.com
• It has stronger creator/business tools than a basic newsletter platform: automations, landing pages, segmentation, digital products, etc. help.kit.com
• So you can start as a simple newsletter and gradually add paid tiers without changing platforms.

How I'd compare the main choices

Substack is probably the simplest choice: publishing is free regardless of subscriber count, and you can switch on paid subscriptions whenever you want. The tradeoff is a 10% cut of paid subscription revenue, plus payment processing. support.substack.com

beehiiv is particularly attractive once you're serious about growth: its free Launch plan supports 2,500 subscribers and unlimited sends, while its paid tier takes 0% of subscription revenue (Stripe processing still applies). www.beehiiv.com

Bottom line:

• Want the best long-term creator platform → Kit
• Want the absolute simplest “newsletter + paid button” → Substack
• Expect rapid growth and care about monetization/growth tools → beehiiv
• Want a full independent publication website → Ghost

If you tell me roughly how many subscribers you expect in year 1 and whether the paid tier will be exclusive articles, a community, or something else, I can narrow it down to one.

If your priority is “start free, build an audience, then turn on paid memberships without having to migrate,” I’d narrow it to Substack vs. beehiiv vs. Ghost.

My pick: Substack if you're just starting

Substack is the least complicated: publishing is free regardless of subscriber count, and when you're ready, you can simply enable paid subscriptions. It supports monthly, annual, and founding-member plans. The downside is that Substack takes 10% of every paid transaction on top of Stripe's processing fees. support.substack.com

So if you don't yet know whether you'll ever monetize, Substack is the lowest-risk choice.

But I'd choose beehiiv if you expect this to become a business

beehiiv's free Launch plan currently supports up to 2,500 subscribers with unlimited sends, and its paid plans add growth/monetization tools. www.sasanova.com

The big advantage is economics: unlike Substack, beehiiv doesn't take a percentage of your subscription revenue. That becomes meaningful once you're making real money.

For example, at $2,000/month in paid subscriptions, Substack's 10% platform cut is about $200/month before payment-processing fees. A flat-fee platform can become much cheaper once revenue grows. tiergauge.com

Ghost is the “I want to own this” choice

Ghost is particularly good if you envision a publication with its own website, branding, and membership system. It has free and paid members, recurring subscriptions, and newsletters built into the platform, with 0% Ghost transaction fees; Stripe's processing fee still applies. ghost.org

The catch is that it's less attractive if your absolute requirement is $0 to start, because Ghost(Pro) is paid.

My ranking for your specific requirement:

1. 🥇 Substack — best if you want to start today with essentially zero friction.
2. 🥈 beehiiv — best if you already think you'll monetize and want stronger business economics.
3. 🥉 Ghost — best if you care most about owning a branded publication/membership business.

If you tell me what kind of newsletter you're planning (personal writing, local news, niche expertise, business, etc.) and roughly how many subscribers you expect in year 1, I can tell you which one I'd personally pick and why.

If your priority is “start free, build an audience, then turn on paid memberships without migrating later”, I’d shortlist these:

My pick by scenario:

Pick beehiiv if:

• You expect this to become a real newsletter business.
• You care about growth tools (referrals, recommendations, analytics, sponsorships).
• You want to avoid giving away a percentage of future paid revenue. www.beehiiv.com

Pick Substack if:

• You mainly want to write and publish immediately.
• You don’t want to think about setup, websites, or payment configuration.
• You’re unsure whether you’ll ever monetize.
• You accept the 10% platform cut once you turn on paid subscriptions. tiergauge.com

Pick Ghost if:

• You’re building a brand, magazine, community, or membership site.
• Owning your audience and website matters more than built-in growth loops.
• You want more control over design and publishing. ghost.org

For most people starting today with your exact requirement, I’d choose:

1. beehiiv — best overall balance
2. Substack — best if you want zero friction
3. Ghost — best if you’re building a serious publication

A useful question: Are you imagining a newsletter that is primarily a personal writing project, or a business/media product? That changes the best choice.

If your priority is “start free, then turn on paid memberships without rebuilding everything,” I’d pick beehiiv.
