Kit vs Substack: Pricing, Automation, and Paid Newsletters

Shortlist Kit when forms, segmentation, and automated follow-up are central to selling your offer. Shortlist Substack when the publication itself is the product and you want its reader-facing publishing workflow. Both can support a paid newsletter. Neither guarantees that readers will find you.

Kit is the product previously called ConvertKit. If you are searching for ConvertKit vs Substack, this comparison covers the current Kit plans and capabilities.

Disclosure: we make Distinctful, which offers a Kit integration. The recommendations below are our interpretation of official documentation, not results from a controlled comparison.

Kit vs Substack at a glance

Automation to evaluate	Sequences and Visual Automations on paid plans	Check the available publication emails against your required follow-up

Start with the Kit pricing matrix and Substack's fee documentation. The table is a decision aid, not a claim that one service has better deliverability or will grow a list faster.

Compare the costs at your expected size

On October 7, 2026, at 1,000 subscribers, Kit Creator is $39 per month with monthly billing or $390 per year. That annual total is $32.50 per month equivalent; the pricing page rounds it to $33. Kit's Free plan covers up to 10,000 subscribers with a different feature set.

Substack's 10% platform fee applies to paid subscription revenue. Free publishing does not incur that platform fee. Payment-processing costs remain separate.

For an illustrative paid newsletter with 100 readers paying $10 per month, subscription revenue is $1,000 per month. Substack's platform fee is $100. Kit Creator's monthly software fee at the stated list size is $39, before applicable transaction costs. The $61 difference is a platform-cost comparison, not a forecast of take-home income or a claim that Creator is the cheapest Kit plan for every paid newsletter.

Compare both your total subscriber count and paying subscriber count. A large free list with little subscription revenue can produce a different decision from a smaller list with many paying readers. The newsletter platform pricing comparison includes beehiiv and another worked example.

Choose around one real reader journey

Suppose you sell a workshop. A useful trial starts with a signup form, delivers the promised resource, sends a short follow-up, and excludes existing buyers from a later sales message. Write that journey down and test the required conditions before purchasing an automation plan. Do not pay for a complicated sequence you do not intend to use.

For a paid publication, test a different journey: a reader finds an article, subscribes, pays, receives the paid edition, and manages their subscription. Check the experience on both email and the web. The best tool for that journey may differ from the best tool for a multi-step product launch.

Still deciding whether to launch at all? Should you start a newsletter? helps establish the promise and workload before choosing software.

Discovery is an opportunity to test

Kit and Substack both offer recommendation features. Substack also has Notes and its reader app. Those surfaces can help readers encounter a publication, but their existence is not evidence that your particular publication will grow faster there.

Keep a record of the sources each provider reports, the topics you publish, and how readers respond. Kit's acquisition documentation explains how supported signup paths record attribution and where information can be missing. A captured source describes a path; it cannot prove a reader's motivation.

If your audience already follows your social posts, start with growing a Kit newsletter from posts. Give each campaign a clear signup destination and test that it works before increasing publishing volume.

Plan migration as several separate jobs

An exported subscriber list is only one part of a move. Check subscriber consent and status, paid subscription continuity, content, images, forms, custom domains, and old article URLs. A successful import does not establish that every old search result or paid subscription still works.

Kit’s Substack migration guide and Stripe integration guide describe different parts of this process. Ask the destination provider to confirm the route for your existing billing setup before canceling anything. Test a small import, compare the fields and counts, and map important archive URLs. Our newsletter migration checklist helps organize those checks.

Owning an export gives you options, but it does not make every part of the audience relationship portable. What owning your audience means explains the distinction.

Make the decision after a small trial

Use one edition, one signup form, and one relevant offer. Choose the platform that completes your required reader journey at a cost you understand. Record what is included in the plan, what needs another service, and what you have not tested.

Once the workflow is working, Distinctful's Kit integration can bring supported newsletter information alongside publishing and offer context. Sending stays with Kit, and connected records do not establish which post caused a subscription or purchase.
