Kit, formerly ConvertKit, is an email marketing platform aimed at creators — newsletters, automations, landing pages, and a tag-based subscriber model rather than rigid lists. It includes visual automation flows and a creator network for cross-recommendations.

Highlights

Tag-based subscribers are flexible and powerful
Strong visual automation builder
Creator-friendly landing pages and forms
Free tier to start

Good for

Email newsletter

Kit is a strong default for creators who want automations and a tag-based audience model rather than clunky lists. For a media-style newsletter with built-in growth and monetisation, Beehiiv is the more modern rival; for programmatic, app-sent email, Resend is the developer tool. Choose Kit when audience automation for a creator business is the goal.
