Overview

Kit, formerly ConvertKit, is an email marketing platform built for creators, newsletter authors and course sellers. It combines one-off broadcasts with automated email sequences, and its visual automation builder turns funnels into drag-and-drop workflows that trigger when someone signs up, clicks a link, buys a product or goes inactive. Every plan includes unlimited landing pages and sign-up forms, and a built-in commerce feature sells digital products and subscriptions natively. Kit exposes a public API alongside an official MCP server, and is priced by the number of subscribers.

Our take

Kit is built for the person whose list is the business, and the native commerce is what separates it from a general mailer: selling a product or a subscription does not need a second platform and its take rate. A company whose newsletter supports a wider marketing effort should pick a marketing automation platform instead, because there is no CRM here and the segmentation is deliberately simple. The free tier is generous but withholds the automation builder and sequences, which are the reason to be here, so treat it as hosting rather than as a plan to stay on.
