Kit (formerly ConvertKit) is email for working creators: forms and landing pages capture subscribers, visual automations route them through sequences, and commerce tools sell digital products and paid newsletters without a separate stack. The rebrand came with a free plan up to 10,000 subscribers — aggressive for the category.
It suits creators treating email as their business channel. Media-scale growth mechanics lean beehiiv; minimalist writers lean Buttondown; small businesses wanting campaigns plus CRM still pick Mailchimp.
