Kit (ConvertKit)

Kit (formerly known as ConvertKit) is an email platform built specifically for creators — bloggers, newsletter writers, podcasters, YouTubers and anyone building their own audience. It's made by a team that targeted content creators from day one instead of big online stores, so the whole tool is tuned to how a single person or a small team works, not a corporate marketing department.

It works simply: you collect email addresses through forms and landing pages you build inside Kit, then send newsletters to your subscribers — either one-off broadcasts or automated sequences that go out on their own at the right time. Kit measures how many people opened your email, what they clicked and how your audience is growing, so you can see exactly what works.
