Most people who decide to start a newsletter spend their first week comparing tools instead of writing. The choice matters less than it feels like it does, but it does matter, because switching email platforms later means migrating subscribers, rebuilding forms, and re-learning an interface. Kit, the tool that was called ConvertKit until it rebranded in 2024, is one of the few platforms built specifically for people who write and sell things on their own. This guide walks through how to set up a working newsletter with it, what the free plan actually gives you, and where the limits show up once you grow.
Why Kit fits solo writers
Kit was started by a blogger who wanted a better way to email his readers, and that origin still shapes the product. The whole system is organized around subscribers and tags rather than separate, siloed lists, which sounds like a small detail but changes how you work. You keep one list of people and attach tags to describe them, so a single reader who downloads a guide and later buys a product stays as one contact instead of three. That keeps your subscriber count honest and your billing lower, since most email tools charge by the number of people you store.
The platform leans toward writing and selling instead of heavy visual design. Emails are plain and text-forward by default, which is closer to how a personal newsletter should read anyway. If you want elaborate, image-heavy campaigns with lots of layout control, Kit will frustrate you. For someone who mostly wants to send words to an audience and occasionally sell a product, the simplicity is the point rather than a missing feature.
Setting up your account and first form
Start with the free Newsletter plan, which covers up to 10,000 subscribers with unlimited email sends. You can sign up and explore the full setup at Kit before paying anything, which is rare among email tools at this size. The first real task is creating a way for people to subscribe, and Kit calls these forms. A form can be a small box embedded in your website, a popup, or a slide-in that appears as someone scrolls.
Build one simple form to begin with and resist the urge to make it clever. Give it a clear headline that says what people get and how often, then connect it to your site or share the hosted version Kit gives you. If you do not have a website yet, Kit also includes landing pages, which are standalone signup pages you can publish without any site of your own. The landing page designs are basic, so do not expect much styling room, but a plain page that loads fast and explains the offer will collect emails just fine.
Writing and sending your first issues
Once people can subscribe, the next job is sending email. In Kit, a one-time email to your whole list or a segment of it is called a broadcast, and this is what most newsletters are. Write it in the editor, pick who receives it, and send or schedule it. The editor stays out of your way, which is good when the content is the thing that matters and bad if you wanted drag-and-drop design blocks.
The piece worth setting up early is a welcome email, so new subscribers hear from you the moment they join instead of waiting for your next send. On the free plan you get a single automation, and a welcome email is the best use of it. An automation in Kit is a flow you build visually, where a trigger like someone subscribing kicks off an action like sending a specific email. Start with one welcome message that introduces you and sets expectations, then expand later if you upgrade.
Where the free plan stops and paid begins
The free plan is genuinely usable, but it has fences. Your emails carry Kit branding, you are limited to that one automation, A/B testing is unavailable, and analytics stay basic. For someone in their first few months with a small list, none of that is fatal. You can write, grow, and send for a long time without paying, which is the main reason to start here rather than on a cheaper-looking competitor that caps you at a few hundred subscribers.
The Creator plan removes the branding and unlocks unlimited automations and email sequences, plus subject-line A/B testing and 24/7 support. It starts at $39 per month for 1,000 subscribers, or about $33 if you pay annually. It is worth knowing that Kit raised prices in September 2025, and the cost climbs as your subscriber count grows, so the tool that was free at the start can get expensive at scale. The top Creator Pro plan, at $79 per month, adds advanced reporting, subscriber scoring, and Kit's built-in referral system, which most solo writers will not need until they are well established.
Growing the list without paying for ads
One feature deserves attention because it is unusual. Kit runs something called the Creator Network, where creators recommend each other's newsletters to their own audiences. When someone subscribes to you, Kit can show them a handful of other newsletters in your niche, and other creators can do the same for you. According to Kit, creators who recommend each other tend to grow their lists faster than those who go it alone, since the recommendations put your newsletter in front of readers who already opt into similar content.
This matters most for solo builders because it is organic growth that does not cost ad money or require a big platform of your own. You set up which creators you are willing to recommend, turn on recommendations for new subscribers, and let the network do quiet, ongoing work in the background. It will not replace your own writing and sharing, but it compounds over time, which is exactly the kind of compounding advantage one person without a marketing budget should look for.
The honest recommendation
Kit is a strong choice if your newsletter is mostly writing, you care about clean automations and tagging, and you might sell digital products to the same audience later. Start free, build one form and one welcome email, send broadcasts consistently, and turn on the Creator Network early so list growth has somewhere to come from. Upgrade to the Creator plan only when the branding bothers you or you need more than one automation, not before. If your plans lean toward design-heavy campaigns or a tight long-term budget, look at cheaper alternatives first, but for most people building an audience around their own words, Kit earns its place.
