Kit's Free Plan Goes to 10,000 Subscribers. What's the Catch?
How this review was built. Pricing, tiers and limits come from the vendor's own pricing page and documentation as of the date above — and where a figure is the vendor's claim, we say so rather than repeat it as fact. Some links on this page are affiliate links: we may earn a commission at no extra cost to you, which is why the drawbacks are printed in full on this page rather than left for you to find later. About the rating. It is our own editorial judgement on a 1–5 scale — not the output of a formula, and not the result of hands-on testing. Treat it as one publication's opinion and read the drawbacks, which are the useful part. See our full methodology & disclosure →
Starting at $33/month
Verdict: Ten thousand subscribers free with unlimited broadcasts is the most generous free tier in email marketing by a wide margin. The catch is real but narrow: the free plan sends broadcasts, not sequences, so you are buying automation when you upgrade — not capacity.
Pros
- ✓Free to 10,000 subscribers — 40× Mailchimp's free contact limit
- ✓Unlimited email broadcasts on the free plan, not a monthly send cap
- ✓Built for writers and creators; the editor gets out of the way
- ✓You can grow a real audience before paying anything
Cons
- ✗Creator starts at $33/month for 1,000 subscribers — the paid entry is high
- ✗Automation is the upgrade trigger, and most people need it sooner than 10,000 subscribers
- ✗Formerly ConvertKit; older articles and integrations still use the old name
- ✗Design flexibility is deliberately limited — plain text by philosophy, not by accident
The number, and whether it is real
Kit — the company formerly called ConvertKit — offers a free plan that carries up to 10,000 subscribers with unlimited email broadcasts.
From Kit's own pricing page, checked August 2026:
| Plan | Price | Subscribers |
|---|---|---|
| Newsletter | $0 | up to 10,000 |
| Creator | $33/mo | from 1,000 |
| Pro | $66/mo | from 1,000 |
That free number is not a typo and it is not a trial. For comparison, [Mailchimp's free plan is 250 contacts](/reviews/mailchimp-review) — Kit's is forty times larger.
So the reasonable reaction is suspicion. Something has to be missing.
What is actually missing
It is not capacity. It is automation.
The free Newsletter plan sends broadcasts — one email, written now, sent to a list or a segment. That is a newsletter, and if a newsletter is what you publish, the free plan does the whole job at any size up to 10,000 people.
What it does not do is sequences: the automated welcome series that fires when someone subscribes, the multi-step launch sequence, the behaviour-triggered follow-up. Those live on Creator at $33/month.
That is a coherent product decision rather than a trap. Kit is betting that writers start by publishing and only later need automation, and that by the time they do they will have an audience worth paying to automate against.
Why the paid entry price looks high
Creator at $33/month for 1,000 subscribers is expensive next to entry tiers elsewhere — [MailerLite's Comfort starts at $12](/reviews/mailerlite-review), [Mailchimp's Essentials at $13](/reviews/mailchimp-review).
Two things make the comparison less unfavourable than it looks.
You were free until you needed automation. A creator who spends a year building to 4,000 subscribers on the free plan has paid nothing during the period when every other tool would have been charging. The lifetime cost is not the monthly price.
You are not paying for subscriber headroom. On most platforms the entry tier is a volume tier and you climb it as your list grows. On Kit the entry tier is a capability tier, and you crossed into it because you wanted sequences, not because you hit a ceiling.
Who should use the free plan and stay there
Anyone publishing a newsletter on a schedule. If your relationship with your list is "I write, you read", broadcasts are the entire feature set you need and 10,000 subscribers is a long runway.
Anyone validating an audience before committing. You can find out whether people want to hear from you without a card on file, and without the artificial urgency of a 14-day trial.
Who will hit the wall early
Anyone selling something. A welcome sequence is not a nice-to-have when you have an offer — it is the mechanism. You will want Creator in month one, and the free plan's generosity is irrelevant to you.
Anyone who needs funnels and checkout as well as email. Kit is a dedicated email tool that has added commerce features; it is not an all-in-one. [Systeme.io's free plan is smaller on contacts at 2,000](/reviews/systeme-io-free-plan-limits) but includes sales funnels, a course platform and affiliate management — a different shape of product for a different job. If you are choosing between them, the question is not which free tier is bigger. It is whether you are publishing or selling.
The honest summary
Kit's free plan is the real thing and the most generous in the category. The catch is narrow and clearly signposted: you get reach for free and pay for automation.
If you write to an audience, start here and pay nothing for a long time. If you sell to one, price Creator from day one and treat the free tier as a trial you happen not to be paying for.

A different approach: Bonfire Terminal
Kit runs in the vendor's cloud — your data is processed on their servers, and you pay every month for as long as you use it. Bonfire Terminal is a different kind of tool: an AI agent that runs as a desktop app on your own machine. No cloud, no API credits, and nothing you type leaves your computer.
To be straight with you: it is not a drop-in replacement for Kit, and we are not going to pretend it is — they do different jobs. It is worth a look if the cloud-subscription model itself is what you want out of, or if you want an AI agent that works privately and offline. If Kit is doing its job for you, keep it.
| Feature | Kit | Bonfire Terminal |
|---|---|---|
| What it is | Cloud email-marketing SaaS | Local AI desktop agent (Rust), bundled with affiliate-marketing training |
| Where it runs | Vendor’s cloud — your data is processed on their servers | On your own machine — no cloud, no API credits, no data leaves your computer |
| What you pay | From $33/month | $27 entry (AI Marketers Club) — includes 21-day Bonfire Terminal access |
| Guarantee | See the vendor’s own terms | 60-day money-back guarantee |
The way in is the AI Marketers Club — $27 one-time, which includes 21 days of Bonfire Terminal access. Keeping it after that is a separate purchase, and the vendor's FAQ states Bonfire Terminal starts at $5,000. We earn a commission if you join, at no extra cost to you — which is exactly why our criticisms of Kit are printed in full above, why we have told you what this is not, and why the $5,000 is in this sentence rather than left for you to discover later.
