Kit vs Substack Comparison 2026
Kit charges a monthly fee based on total subscriber count, free up to 10,000, plus 3.5 percent on anything sold through it. Substack charges nothing upfront at all, taking 10 percent of paid subscription revenue only, with distribution through Notes and recommendations from other writers built in. The axis is what gets taxed: Kit's fee tracks your whole list including subscribers who never pay, while Substack's cut only ever touches money that actually changes hands.

Kit
Email marketing built around automation
Kit is the one to pick when the sequences matter more than the newsletter. Visual automations, tagging and conditional content are genuinely good, and the creator network sends real signups. The editor is plainer than its competitors.
Our note
Kit against beehiiv is the real decision here, and it turns on which half of the job matters more. Kit is better at what happens after somebody subscribes, beehiiv at getting them to subscribe at all.

Substack
Paid subscriptions with a reader network attached
Substack takes 10 percent of subscription revenue and gives you distribution in return, through Notes and recommendations from other writers. That trade is good early and expensive later. Exporting your list is easy, which makes it a reasonable place to start.
Our note
Why people weigh these two
- Substack instead of Kit
- Substack costs nothing to run and comes with a reader network that can find new subscribers on its own, trading Kit's automation for built-in discovery.
- Kit instead of Substack
- Kit from $29 with a free tier is built around automation and takes no cut of subscriptions, where Substack charges a percentage.
Which one should you pick
Choose Kit if the list is large but mostly free, or the automation itself is the point, since the monthly fee is based on total subscribers rather than paying ones and 10,000 free subscribers cost nothing at all. Selling a paid newsletter through Kit costs 3.5 percent plus 30 cents, well under Substack's 10 percent once real subscription revenue is flowing.
Choose Substack if you have no list yet and no evidence anyone will pay for the writing, since there is nothing to configure and 10 percent of nothing is nothing. Move the list the year that 10 percent starts costing more than a flat platform would, since exporting is easy and that crossover arrives sooner than most writers plan for.
Common questions
- Which one is cheaper for a paid newsletter?
- It depends on how much of the list actually pays. Kit charges a subscriber-based monthly fee plus 3.5 percent on sales; Substack charges nothing upfront but 10 percent of paid subscription revenue. A large free list with a small paying segment can favor Kit, since Substack only taxes the paying part but at a much higher rate.
- Does Substack charge anything before I earn money?
- No, there is no plan to choose and no monthly fee at all. The 10 percent only applies once a reader actually pays for a subscription, which is what makes it cheap to start and potentially expensive later.
- Which one helps get new subscribers through a built-in network?
- Substack does, through Notes and recommendations from other writers, which is where most Substack growth actually comes from. Kit has a Creator Network too, where other writers recommend you at their own signup screen, at no extra cost.
- Can I export my list and leave either platform?
- Substack's listing states exporting your list is easy, which makes it a reasonable place to start. Kit's listing does not focus on export as a stated feature, though its API provides documented access to subscriber data.
