How we know: we tested Systeme.io hands-on in our own free-plan account. Everything here about Kit comes from its published pricing page and documentation, checked on the date shown — we have not run a Kit account ourselves, and we would rather say so than imply otherwise.
Our verdict
This is the one comparison in our series where the competitor’s free plan is actually bigger: Kit’s free tier holds up to 10,000 subscribers, five times Systeme.io’s 2,000-contact limit. Systeme.io still wins on structure (real multi-step funnels, not just product pages) and fees (0% versus Kit’s 3.5% + 30¢ on every tier). Which one wins for you depends on whether audience size or funnel structure matters more right now.

Kit (formerly ConvertKit) is built for creators — newsletter writers, YouTubers, podcasters, authors. Systeme.io is built for funnel-first businesses. Both let you sell digital products, but the free-tier math actually favors Kit here, which is unusual enough in this comparison series that it’s worth stating plainly up front.
Pricing, side by side
List prices as of September 6, 2026, monthly billing at Kit’s 1,000-subscriber tier, checked directly on each company’s pricing page.
| Tier | Systeme.io | Kit |
|---|---|---|
| Free | $0 — up to 2,000 contacts, 3 funnels, 0% fees | $0 — up to 10,000 subscribers, unlimited landing pages, unlimited broadcasts |
| Entry | $17/mo — 10 funnels, 5,000 contacts | $33/mo (Creator) — unlimited automations, remove branding, SMS marketing |
| Mid | $47/mo — 50 funnels, 10,000 contacts | — |
| Top | $97/mo — unlimited everything | $66/mo (Pro) — Subscriber Signals, engagement analytics, unlimited users |
The detail worth noting, both directions: Kit’s free plan is genuinely larger by subscriber count — 10,000 versus Systeme.io’s 2,000, at the same $0. But Kit charges 3.5% + 30¢ on every digital product or subscription sale, on every tier including Pro. Systeme.io charges 0% transaction fees at every tier, including free. To Kit’s credit, it’s transparent about the breakdown: most of that 3.5% is standard card-processing cost, and Kit itself keeps roughly 0.6% of it.

Where the money actually goes
What Kit has that Systeme.io does not
- A free plan that scales to 10,000 subscribers before you need to pay anything — five times Systeme.io’s free-tier ceiling.
- Kit MCP, connecting Claude, ChatGPT, and other AI tools directly to your subscriber data, on the Creator tier up.
- Paid newsletter and recurring subscription billing built specifically for the newsletter-creator business model, with a built-in referral system (a free SparkLoop plan worth $99/mo).
- Subscriber Signals on Pro — automatic audience research and demographic data on your list.
That free tier is the honest headline here, and it is the one place in this whole comparison series where a competitor’s free plan beats Systeme.io’s outright — 10,000 subscribers against 2,000, at the same $0. If your list is the business and you are nowhere near needing funnels, that is the number that matters.
See Kit’s free planAffiliate link — see our disclosure. Kit charges 3.5% + 30¢ per sale on that free plan; the table above has the trade-off.
What Systeme.io has that Kit does not
- 0% transaction fees at every tier, including free. Kit charges 3.5% + 30¢ on every product sale, on every plan.
- Real multi-step sales funnels — Kit has landing pages and simple product checkout pages, but not a chained funnel builder with upsells the way Systeme.io’s core product works.
- A dedicated course and membership module built into the platform, versus Kit’s simpler digital-product delivery.
- Unlimited sub-accounts on every plan, including free.
Two questions that decide it
1. Is your list already close to 2,000, or well under it?
If you’re a newsletter creator with a growing list under 10,000 subscribers who mostly sends broadcasts and sells the occasional digital product, Kit’s free plan covers more of your actual use case for longer. If you need funnels, courses, or you’ll hit 2,000 contacts quickly, that free-tier size advantage matters less.
2. How much of your revenue runs through digital product sales?
Kit’s 3.5% + 30¢ fee applies to every sale, on every plan, forever — there’s no tier where it goes away. On a $50,000/year digital product business, that’s roughly $1,750 in fees Systeme.io wouldn’t charge. Run the math on your actual sales volume before assuming the cheaper monthly price is the cheaper platform.
Frequently asked questions
Does Kit have a bigger free plan than Systeme.io?
Yes, by subscriber count — Kit’s free plan holds up to 10,000 subscribers versus Systeme.io’s 2,000 contacts, both at $0. Systeme.io’s free plan includes real sales funnels and 0% transaction fees, which Kit’s free plan does not.
Does Kit charge transaction fees?
Yes — 3.5% + 30¢ per sale on digital products and subscriptions, on every plan including Pro. Kit states most of that is standard payment-processing cost and it keeps about 0.6% itself. Systeme.io charges 0% on every tier.
Does Kit have sales funnels?
Not in the multi-step sense Systeme.io offers. Kit has landing pages and simple product checkout pages, but doesn’t chain them into a funnel with upsells the way a dedicated funnel builder does.
Is Kit or Systeme.io better for a newsletter-first creator business?
Kit, if your business is primarily newsletter and content-driven with occasional digital product sales — its free tier, referral system, and paid-newsletter tools are purpose-built for that. Systeme.io is the better fit once funnels, courses, or multiple products become central to the business.
I’ve been building and maintaining websites for about ten years. The first one is still online a decade later, and I still fix it when something breaks — which is how I learned that the interesting part of any platform is not the launch, it’s year three. I co-owned that site’s business, though I am not a co-owner today; the business itself has since closed. Separately, I have also run an online store on Shopify, until the fees pushed me onto a different payment system. Today I choose the host, the theme and write the plugins that run this site, and I pay for the tools I test out of my own pocket. More on the About page, and exactly what we did and did not test in how we test.
