If you’re testing whether people will actually pay, I’d start with substack.com.

Why it fits a part-time creator:

• $0 to start and no monthly platform fee. Substack Support
• Built-in paid subscriptions, paywalled posts, and Stripe payment collection—you don't need to stitch together a checkout system. Substack Support
• You can offer monthly, annual, and founding-member plans. Substack Support
• The tradeoff is a 10% Substack fee on paid revenue, plus Stripe processing/billing fees. Substack Support

The alternative I'd consider

beehiiv.com is better if you're already confident you'll monetize and expect meaningful revenue. It takes 0% of subscription revenue (Stripe fees still apply), and includes paywalls and paid subscription tiers. Beehiiv Beehiiv Its paid-subscription tools require a paid plan, though, so it's less attractive for a very small experiment. Beehiiv

Rule of thumb: if you're testing “Will anyone pay?”, use Substack. If you're testing “How do I build a paid newsletter business?” and expect revenue soon, look at beehiiv.

For example, at $500/month in paid subscriptions, Substack's 10% platform cut alone is $50/month, before Stripe fees—so the economics can shift fairly quickly as you grow. Substack Support

For a part-time creator testing paid issues, I’d narrow it to these:

My pick for your situation: Substack

If your goal is specifically “let me test whether readers will actually pay, without committing money first,” Substack is the lowest-friction choice. Publishing is free, and you can turn on paid subscriptions through its built-in Stripe integration. You set monthly, annual, and founding-member prices yourself. support.substack.com

The tradeoff is substantial: Substack takes 10% of paid transactions, on top of Stripe's processing fees. support.substack.com

Substack pricing and fees

If you already have an audience: beehiiv

beehiiv pricing

beehiiv's free Launch plan supports up to 2,500 subscribers, but its paid-subscription functionality is on the Scale plan, currently listed at $43/month when billed annually. It takes 0% of paid subscription revenue, leaving Stripe's processing fee. www.beehiiv.com

So I'd think of it this way:

• < ~$400/month in paid revenue: Substack's simplicity may be worth the 10% cut.
• Several hundred dollars/month and growing: beehiiv's 0% platform fee becomes more attractive.
• You want your own publishing business/site: Ghost is worth considering, but its monthly cost makes it less suitable for an initial experiment. Ghost charges 0% transaction fees, but paid subscriptions require its higher-tier plans. ghost.org

For a low-risk experiment, I'd start with Substack, put just 10–20% of your newsletter behind a $5–10/month paid tier, and see whether readers convert before investing in a more sophisticated setup.

For a part-time creator testing paid newsletter issues, I’d narrow it to these:

My take

Substack is the lowest-friction choice for your experiment. You can publish for free, turn on paid subscriptions, and connect Stripe without paying a monthly platform fee. Substack currently takes 10% of paid transactions, plus Stripe's processing/billing fees. support.substack.com

That makes it particularly good if you're asking: “Will anyone actually pay for my premium issues?” You can test without committing to a monthly software bill.

beehiiv is more attractive if the test succeeds. Its paid-subscription feature takes 0% of subscription revenue, with Stripe's processing fee being the main payment cost. However, the monetization features are on its paid plans, which currently start at $49/month. www.beehiiv.com

Ghost is the better ownership-oriented option. Its Publisher plan is currently $29/month when billed yearly, supports paid subscriptions through Stripe, and Ghost takes 0% of transactions. ghost.org

For your specific situation: start with Substack. If you get enough paying readers that the 10% fee becomes meaningful, then consider moving to beehiiv or Ghost. That lets you validate willingness to pay before optimizing your platform economics.

For a part-time creator testing paid issues, I’d narrow it to these:

My practical take

Substack is the simplest place to validate the idea. You can publish for free, turn on paid subscriptions, set monthly/yearly/founding-member pricing, and connect Stripe without paying a monthly platform fee. support.substack.com

The tradeoff is substantial once you have revenue: Substack takes 10% of each paid transaction, on top of Stripe's processing fees. support.substack.com

beehiiv is potentially better once you're confident people will pay. It takes 0% of paid-subscription revenue, with Stripe's standard processing fee, but its paid-subscription functionality is on paid plans; its free Launch plan is mainly useful for building/testing the audience before monetization. www.beehiiv.com

Ghost also takes 0% of subscription revenue, but its monthly cost makes less sense for a very small experiment. Its Publisher plan is currently $29/month when billed yearly and includes paid subscriptions. www.beehiiv.comghost.org

Bottom line: If your immediate goal is “I want to see whether readers will actually pay, with essentially no financial commitment,” start with Substack. If the experiment works and the 10% platform cut becomes meaningful, beehiiv is worth considering as a next step.

For a first test, I'd also consider one paid tier around $5–10/month rather than multiple tiers—keep the experiment simple enough that you learn whether the content itself converts.

For a part-time creator testing whether people will pay, I’d look at these three:

Best low-cost experiment: Substack. You can publish for free, turn on paid subscriptions, connect Stripe, and start charging without committing to a monthly platform fee. support.substack.com The tradeoff is substantial: Substack takes 10% of paid transactions, on top of Stripe's processing fees. support.substack.com

Best if you expect the experiment to work: beehiiv. Its free Launch plan supports up to 2,500 subscribers, but paid subscriptions are currently a paid-plan feature. Once you're on a qualifying plan, beehiiv takes 0% of subscription revenue, leaving Stripe's 2.9% + $0.30 processing fee. www.beehiiv.com

Ghost is attractive if you want your own publication/site and don't mind a monthly cost, but it's harder to justify for a small initial experiment: the current Publisher plan is $29/month billed annually and has 0% transaction fees. ghost.org

My practical take: start with Substack if your priority is spending $0 to validate demand. If you get meaningful paid traction, reassess whether beehiiv's fixed cost + lower payment take is better economically.

For a part-time creator testing whether readers will pay, I’d narrow it to three:

My take: start with Substack

For your particular use case, Substack is the lowest-friction experiment. Publishing is free, you can turn on paid subscriptions without buying a separate website or payment system, and readers can choose monthly or annual plans. support.substack.comwww.beehiiv.comwww.beehiiv.com

The tradeoff is meaningful: Substack takes 10% of every paid transaction, in addition to Stripe's processing/billing fees. support.substack.com

If you charge $5/month, for example, you don't need to pay anything upfront—but roughly 10% + payment processing comes out of each subscription.

When I'd choose beehiiv instead

beehiiv is more attractive if you already have an audience and expect paid subscriptions to become a meaningful revenue stream. It takes 0% of subscription revenue, with Stripe's processing fee being the main payment cost. www.beehiiv.com

The catch for your situation is that paid subscriptions are on beehiiv's paid plans, so it's not as cheap for a tiny experiment as Substack. www.beehiiv.com

And Ghost?

Ghost is excellent if you're building a publication you expect to own long-term: it takes 0% transaction fees, connects directly to your Stripe account, and supports paid memberships. But its managed hosting starts at $18/month billed annually, making it harder to justify for an initial low-risk test. ghost.org

Bottom line: If your question is “Will anyone actually pay me for this?”, I'd use Substack first. If you prove demand and the 10% fee starts becoming significant, then consider moving to a 0%-platform-fee option like beehiiv or Ghost.

For a part-time creator testing paid issues, I’d narrow it to these:

Substack is probably the lowest-risk way to test the idea: publishing costs nothing, you can turn on monthly/annual paid subscriptions, and Substack handles the payment flow. The tradeoff is its 10% cut of every paid transaction, on top of Stripe processing. support.substack.com

Ghost is more economical once revenue gets substantial. Its paid-subscription plan charges no platform transaction fee, with payments going directly through your Stripe account, but you pay the monthly Ghost subscription regardless of whether anyone buys. ghost.org

For your situation, I'd start with Substack. If you're simply trying to answer “Will people actually pay for my issues?” a $0 platform cost is valuable. Once you have enough recurring revenue that 10% becomes painful, you can reconsider Ghost or another 0%-take platform.

A rough break-even illustrates it: at $100/month in paid revenue, Substack's platform fee is about $10; at $300/month, it's $30. A $29/month Ghost plan starts looking more attractive around that range, before considering Stripe fees. ghost.org

If you tell me roughly how many free subscribers you have and what you'd charge per issue/month, I can calculate the actual monthly cost for Substack vs. Ghost vs. beehiiv.

For a part-time creator testing whether readers will actually pay, I’d look first at Substack.

Best fit: Substack

• $0 upfront to publish and build your audience.
• Built-in paid subscriptions, including monthly and annual plans.
• Payments are handled through Stripe, so you don't need to stitch together a separate checkout system. support.substack.com
• The catch: Substack takes 10% of paid subscription revenue, in addition to Stripe's processing fees. support.substack.com
• This makes it particularly attractive for testing: if nobody buys, you don't have a monthly software bill.

If you expect the test to work: Ghost

Ghost is more economical once you're generating meaningful recurring revenue. Its hosted Starter plan is currently $18/month billed annually, while paid subscriptions are available on the Publisher tier; Ghost takes 0% of subscription revenue, with Stripe processing fees still applying. ghost.org

Rule of thumb:

• <$180/month in paid revenue → Substack's 10% is cheaper than an $18/month platform fee.
• >$180/month → Ghost's flat fee starts becoming cheaper. tiergauge.com

My practical choice: Start on Substack for 2–3 months, offer one paid tier (e.g. $5–10/month), and see whether people convert. If you get enough paying readers that the 10% cut starts bothering you, migrating to a 0%-platform-fee service becomes worthwhile.

If you tell me roughly how many free subscribers you have now and what you'd charge for a paid issue, I can calculate the break-even point between Substack, Ghost, and beehiiv for you.

For a part-time creator testing paid issues, I’d focus on minimizing upfront cost and setup rather than optimizing for scale.

Best low-cost options

Current 2026 comparisons put Substack at $0 upfront with a 10% revenue share, while Buttondown and Ghost use flat fees with no platform cut. tiergauge.com

For your specific situation, Substack is the simplest experiment. You can publish free issues, turn on paid subscriptions when you're ready, and avoid committing to a monthly platform bill. The tradeoff is that once you have meaningful paid revenue, its 10% cut becomes expensive. thrivewithcarrie.substack.com

If you expect to charge, say, $5–10/month and only have a handful of paying readers initially, that simplicity is valuable. If the test works and revenue grows, you can reassess a 0%-platform-fee option such as Buttondown or Ghost.

Substack · Buttondown pricing · Ghost pricing · beehiiv pricing

For a part-time creator testing paid issues, I’d look at these three:

Buttondown specifically supports paid-exclusive emails, monthly/yearly subscriptions, pay-what-you-want pricing, and even per-email charging, which is unusually well suited to your idea of testing individual paid issues. docs.buttondown.combuttondown.com

Buttondown pricing

My practical take: start with Buttondown if you already have an audience and want to experiment without giving up 10% of every sale. Its paid-subscription add-on is $9/month, and it doesn't take a percentage of subscription revenue; Stripe's processing fees still apply. docs.buttondown.combuttondown.com

If you want the absolute simplest setup and don't mind the revenue share, Substack is easier: publishing is free, and you can switch on paid subscriptions directly through its Stripe integration. Substack currently takes 10% of paid transactions, on top of Stripe fees. support.substack.com

So for a small experiment, I'd rank them:

1. Buttondown — best economics for testing
2. Substack — easiest launch/discovery
3. Ghost — best once you're building a bigger owned publication

If by “paid issues” you mean selling individual one-off issues rather than a recurring subscription, Buttondown is particularly interesting because it supports a per-email pricing model. docs.buttondown.combuttondown.comsupport.substack.com

If your goal is to test paid issues with as little upfront cost as possible, I’d look at these two:

My take: Kit for a paid-issue experiment

Kit lets you run a paid newsletter on its free plan, with recurring subscriptions and payment collection built in. Its published fee is 3.5% + $0.30 per transaction, including payment processing. kit.comhelp.kit.com

So, for example, on a $10 paid issue/subscription, you'd pay roughly $0.65 in fees versus roughly $1.59 on Substack before any applicable recurring billing fees.

It also supports monthly, quarterly, and annual subscriptions, and you can use its checkout/product pages without cobbling together Stripe + another newsletter service. kit.comhelp.kit.com

When I'd choose Substack instead

Choose Substack if your priority is maximum simplicity and having your newsletter live in an established reader ecosystem. There's no monthly platform fee, and enabling payments is essentially connecting Stripe and setting your subscription prices. support.substack.com

The tradeoff is substantial: Substack takes 10% of every paid transaction, on top of Stripe's processing fees. support.substack.com

Bottom line: For a part-time creator who wants to experiment rather than commit to a business platform, Kit is the lower-cost test. If you care more about Substack's publishing/discovery experience than minimizing fees, use Substack.

If you tell me roughly how many free subscribers you have and what you'd charge per paid issue, I can run the numbers for both and show you the break-even point.

For a part-time creator testing whether people will pay, I’d look at these three:

My take for your situation

Start with Substack if your priority is testing the idea with essentially zero upfront cost. Publishing is free, and you only incur costs when you turn on paid subscriptions. Substack takes 10% of each paid transaction, plus Stripe processing fees. support.substack.com

The tradeoff is that if paid subscriptions take off, that 10% becomes significant. For example, at $500/month in subscriber revenue, that's roughly $50/month to Substack before payment-processing fees.

Buttondown is the interesting alternative if you already have an audience and want to keep more of your revenue. Its paid-subscription add-on is currently $9/month, and Buttondown says it takes no additional fee from paid subscriptions beyond Stripe's processing costs. buttondown.com

beehiiv is attractive if you expect the newsletter to become a bigger business, but I'd consider it overkill for an initial test: paid subscriptions require the Scale plan, currently $43/month, although it takes 0% of subscription revenue. buttondown.comwww.beehiiv.com

Bottom line: I'd use Substack for a low-risk 30–90 day validation test, then consider moving to Buttondown or beehiiv if you're consistently generating enough paid revenue that Substack's 10% cut matters. tiergauge.com

If you tell me roughly how many free subscribers you have and what you'd charge per month, I can calculate the break-even point between Substack, Buttondown, and beehiiv.

If your main goal is testing paid issues with minimal upfront cost, I’d look at these:

My practical pick: Substack

For a part-time creator just validating whether people will pay, Substack has the lowest financial risk. Publishing is free, there are no subscriber limits on the free tier, and you only pay Substack when you make a paid subscription sale. Its cut is 10% of each paid transaction, plus Stripe processing fees. support.substack.com

So if you sold 20 subscriptions at $5/month, that's $100/month in gross revenue; Substack's platform cut would be $10, before Stripe fees. That's considerably easier to justify while you're still testing.

beehiiv is more attractive once you're confident the paid model works: its Scale plan has 0% platform take on paid subscriptions, with Stripe's processing fee remaining, but the plan currently costs $43/month when billed annually. www.beehiiv.com

Ghost also takes 0% of subscription revenue and connects directly to Stripe, but its managed hosting starts at $18/month billed annually, so I'd consider it more of a "I'm building this into a real publication" choice than a low-risk experiment. ghost.org

Bottom line: Start with Substack if you're testing whether readers will pay at all. Once you're consistently making more than roughly $180/month in paid revenue, the economics of a flat-fee, 0%-take platform start becoming more compelling. tiergauge.com

For a part-time creator testing whether people will pay, I’d look at Kit and Substack first.

My practical pick: Kit. Its free plan lets you sell paid newsletters, and Kit handles checkout/payment processing through Stripe. The current fee is 3.5% + $0.30 per transaction, with no monthly fee on the free plan. kit.com

For example, at $7/month, 20 paid subscribers would generate $140/month. Kit's transaction fees would be roughly $5.50, leaving about $134.50 before other taxes/fees.

Substack is easier if you value simplicity over margins. There's no monthly platform fee, but Substack takes 10% of paid subscription revenue, on top of Stripe's processing fees. support.substack.com

So I'd choose:

• Want to run a small paid experiment: Kit
• Want the least setup/technical work: Substack
• Expect to grow substantially: beehiiv—the platform currently takes 0% of subscription revenue, although its paid subscription tools require a paid plan. www.beehiiv.com

If your goal is specifically “test 1–3 paid issues without committing to a monthly software bill,” Kit is probably the strongest fit.
