- What it does
- Grow a newsletter with forms and landing pages, send broadcasts and automated sequences, and sell paid subscriptions or digital products to the same list.
- Our take
- Founders building an audience before or beside the product, from a waitlist to a paid newsletter. Kit is free up to 10,000 subscribers, sells subscriptions and digital products to the same list, and lets Claude or ChatGPT work in your account through its MCP server.
- Pricing
- FreemiumMid priceFree up to 10,000 subscribers, with unlimited landing pages, forms and broadcasts, but no automations or sequences, one user and Kit's branding left on. Paid plans are priced by list size, billed monthly: Creator is $39 a month up to 1,000 subscribers, $59 at 3,000, $89 at 5,000 and $139 at 10,000; Pro is $79, $99, $139 and $189 at the same sizes, as checked on 30 October 2026. Paying yearly costs 10 months for 12, so Creator at 1,000 subscribers is $390 a year. Kit bills for confirmed subscribers only, never unsubscribed, bounced or unconfirmed ones, and moves you up a tier automatically when the list passes it. Paid newsletters and digital products cost 3.5% plus 30 cents a sale, card processing included. New customers can have a full refund within 30 days of their first payment.
The IndieHacked breakdown
What it does
Kit runs a newsletter from one subscriber list: forms and landing pages collect sign-ups, broadcasts send each issue, and tags and segments sort readers by what they signed up for. On the paid plans, visual automations and email sequences send a welcome series or a launch on their own, and Kit's MCP server lets Claude, ChatGPT, Cursor and other AI tools read your stats, tag subscribers and draft broadcasts, with nothing sent until you approve it.
The list can also earn. Paid newsletters and digital products run on every plan, including the free one, with payments through Stripe at 3.5% plus 30 cents a sale. Newsletters on Kit can recommend each other at no cost; on paid plans you can also pay to appear in other creators' sign-up flows, and take sponsored placements from brands Kit matches to your list, paid per click.
Who it suits
Founders building an audience before or beside the product: a waitlist, a weekly newsletter, a course or a digital download. The free plan holds up to 10,000 subscribers, so a list can grow for a long time before it costs anything, and Kit bills only for confirmed subscribers, not the ones who left or bounced.
It also fits a founder who sells to that list directly. A paid tier or an ebook sits in the same account as the newsletter, without a separate store or membership tool, and on a paid plan Kit's team rebuilds your forms, templates and automations from the tool you are leaving.
Not the right fit for
Founders whose app needs to send sign-up links, password resets and receipts. Kit is built around a subscriber list and its broadcasts; product email belongs with a transactional service such as Postmark, reviewed here, which keeps that mail apart from marketing.
Founders running an online store who want email driven by orders and abandoned carts. Kit's own comparison lists 100+ native integrations to Mailchimp's 300+, and marks WooCommerce cart-abandonment emails on Mailchimp's side; Mailchimp, reviewed here, connects Shopify, WooCommerce and Square.
