Kit Review: The Free Plan Is Generous — You Pay When You Want Automation

The problem: your newsletter works, but everything after "send" is manual

You write a newsletter, people subscribe, and you send it. That part is easy, and most free email tools handle it. The work starts after that: someone new joins and nobody welcomes them, a reader asks how to buy your guide and you answer by hand, and the people who already bought something get the same emails as the people who have never bought anything. None of that is hard to do once. It is hard to do every time, for every subscriber, without forgetting someone.

That is the exact moment this review is written for. You are a creator — a writer, a teacher, a coach, someone whose business is an audience — and you want the newsletter to keep working after you press send. Kit, the tool formerly known as ConvertKit, is built for that job. The question is not whether it sends email well. It is whether the free plan actually covers what you need, and what the first paid step buys you.

The short answer is unusual for this kind of tool: the free plan is genuinely generous, and the point where you start paying is not your list size. It is automation.

What Kit does

Kit is an email marketing service built for creators. At its core it does three jobs: it stores your subscriber list, it sends your emails to that list, and it helps you collect new subscribers. On top of that it adds the things creators actually sell — digital products, paid newsletters, and paid recommendations — in the same place as the emails. Three concrete examples of how a solo creator actually uses it:

1. A welcome sequence that runs while you are doing other work. When someone joins your list, they can receive a short series of emails over the following days: the free resource they signed up for, an introduction to who you are, and an invitation to your paid product or service. You write it once, and every new subscriber gets the same careful introduction, whether they join on a Tuesday morning or at midnight on a Sunday.

2. Selling a digital product without bolting on a shop. You write a guide, a template, or a short course, put it up for sale inside Kit, and link to it from your newsletter. A reader buys, the payment is handled, and the buyer is tagged so you can follow up with them differently from everyone else. Kit takes 3.5% plus 30 cents on each sale, on every plan including the free one, so the cost only appears when money comes in.

3. Treating buyers and readers as different audiences. Tags and segments let you split your list by what people actually did: who bought, who clicked, who signed up for a particular freebie. A launch email goes to the people who have shown interest, not to your whole list, and a thank-you goes to buyers instead of another sales pitch. For a creator whose list is also a customer base, this is the difference between an audience and a mailing list.

The free plan, and what changes when you pay

Kit's free Newsletter plan costs $0 and covers up to 10,000 subscribers with unlimited email sends, unlimited forms and landing pages, and the ability to sell digital products and paid subscriptions. That is a large free allowance — far larger than most email tools offer — and it stays free while your list grows into the thousands. For a creator whose newsletter is still mainly "write it and send it," the free plan can carry you a long way.

What the free plan does not give you is automation. It includes one basic visual automation and one email sequence, which is enough to try the idea, but not enough to run a real welcome series, a launch sequence, and a follow-up flow at the same time. It also keeps Kit's branding on your forms and locks out integrations with tools like Zapier and Make. So the moment you want the newsletter to do follow-up work on its own, you hit the wall — not because your list got too big, but because you want the tool to do more.

That is what the Creator plan is for. It starts at $39 per month for up to 1,000 subscribers ($390 a year, about $33 a month, if you pay annually) and adds unlimited visual automations and email sequences, integrations, removal of Kit branding, and a second user seat. The Pro plan starts at $79 per month and adds more advanced reporting and deliverability tools. Both paid plans come with a 14-day free trial and no card is required to start it. One thing to know before you commit: prices rise with your list size — at 10,000 subscribers, Creator is $139 a month — so the bill grows as your audience does, which is fair as long as you expect it.

That pricing shape is the honest trade-off at the heart of Kit. The free plan is not a short trial dressed up as a plan; it is a real home for a growing newsletter. You pay when you want the work done for you — automation, sequences, and selling tools that run without you — and the first paid step is priced for a creator, not a marketing department.

Who should not use Kit

No tool fits everyone, and this one has clear edges. You should probably look elsewhere if:

• You only send a plain newsletter by hand. If you write one email a week, send it to everyone, and never need a welcome sequence or a product sale, the free plan already gives you everything — and the paid plans buy you features you will never open.
• You need a sales CRM, not an email tool. If your main need is pipelines, deal tracking, and team permissions for a sales organisation, Kit is the wrong category. It is built around an audience, not a sales team.
• Your main need is transactional email for an app. Receipts, password resets, and notifications belong in a transactional sending service, not in a newsletter tool.
• The per-sale fee bothers you. Kit takes 3.5% plus 30 cents on every product or subscription sale, on every plan. If you sell high volumes of low-priced items, that cut adds up, and a tool with a flat fee or no commerce cut may suit you better.

The honest conclusion

If your problem is the one at the top of this page — a newsletter that works, but everything after "send" is done by hand — Kit is a sensible answer. Start on the free plan, which is genuinely free up to 10,000 subscribers, and run your newsletter through it until the lack of automation is the thing slowing you down. Only then take the $39 step to Creator, when the welcome emails and follow-ups you want are worth more than the manual work they replace. That is exactly how a tool like this should be adopted: after it has proven itself in your weekly routine, not before.
