Today we’re talking about Kit. A lot of you probably already know which Kit I mean. But some people are like me: when we get something new to study, we read the name and wonder, “Wait, is this about a makeup kit or a cricket kit?”
So sorry, beginners, but it’s neither. Kit is a tool, and the tool is actually called Kit. It used to be called ConvertKit, but the name was changed to Kit.
In this blog, we’ll cover who made Kit and why, what it does, what it costs, and why it’s better than other tools.
Kit was built by a creator, for creators. His name is Nathan Barry.
Before Kit, he had used plenty of tools like Mailchimp, Beehiiv, Kajabi, and Substack. After a while he got fed up and realised something: these tools are great for their own business models, but they aren’t right for a creator. So he thought, “Why not build a tool whose whole purpose is the creator?” That’s how Kit was born.
Kit is an email marketing platform, and today it’s a big name in the space. It works through email. You can send a message to 100+ people at once, targeted according to your audience’s and subscribers’ interests. It helps you grow, and through that, your business grows too.




Look, tools like Beehiiv, Kajabi, Mailchimp, and Substack are all out there. Kit stands apart because of what it offers, and it’s easy to use too:

This is the question on everyone’s mind. Compared to other tools, it’s among the cheapest.
Some of you might be wondering this. Yes, you can use any AI you like. Let it handle the boring stuff like research and drafting. The rest of the content, and the style and voice, should be completely yours.
You don’t need to buy any extra paid e-commerce plan. Kit has a built-in commerce feature where you can sell paid newsletters, templates, digital PDFs, courses, and e-books. And unlike other tools, Kit doesn’t charge high fees. It takes only 0.6% plus card processing.
This is the most important part. Kit is not for non-creators. If you’re like me and think that posting your photo on a story makes you a creator, then my friend, let me tell you: no, it doesn’t.
Also, if you want to sell clothes, shoes, or any physical product, this isn’t the tool for you. For that, you’d want something like Shopify. And if you need complex shopping features or B2B features, Kit won’t help you there either. Use something like Mailchimp instead.
That was my take on Kit.
Empirically verified answers to common architectural and evaluation questions.
Kit was built by creator Nathan Barry to give creators an email marketing tool designed around their business models, rather than corporate e-commerce.
Every architectural decision in Email Infrastructure / Outreach involves explicit engineering trade-offs between raw compute cost, throughput guarantees, and operational maintenance friction. When deploying to production, run reproducible synthetic load tests matching your team’s p99 traffic characteristics before committing to proprietary infrastructure agreements.
