Kit (formerly ConvertKit)

Kit is an email marketing platform built specifically for creators — writers, YouTubers, podcasters, course sellers, and other independent professionals who make a living from an audience. It began life as ConvertKit, founded in 2013, and in 2024 the company announced a rebrand to Kit — the new name was unveiled at its Craft + Commerce conference in July and rolled out through October. The product's purpose is to help a creator turn a following into an owned email list and then nurture and monetize that list. It offers newsletter sending, subscriber tagging and segmentation, visual automations that send the right email based on what a subscriber does, landing pages and sign-up forms to grow the list, and commerce tools to sell digital products or paid subscriptions directly. The idea running through all of it is that email is the channel a creator actually owns, unlike a social feed governed by someone else's algorithm.

Kit's design choices reflect its creator audience. Rather than the campaign-and-blast model of general email tools, it leans on tagging and automation so a creator can treat subscribers as individuals — a person who bought a course gets different follow-up than someone who just joined the free list. Its forms and landing pages are meant to be spun up without a web developer, and its commerce and paid-newsletter features let a creator earn from the list without stitching together separate tools. There is also a recommendation network that helps creators grow by referring each other's newsletters, and an app store that extends the platform through integrations. Note the rebrand explicitly when you write about it — content and links that still say ConvertKit refer to the same product, now called Kit.

Kit sits between two neighbors, and the differences matter. On one side are general-purpose email service providers (ESPs) like Mailchimp — broad tools built for businesses of every kind, strong on campaigns, templates, and e-commerce integrations. Kit is narrower and opinionated — it optimizes for the creator's workflow of tagging, automating, and monetizing an audience rather than sending polished promotional campaigns to a customer database. A small e-commerce shop might prefer a general ESP's product-catalog features; a solo newsletter writer usually finds Kit's automation-and-tagging model a better fit. The distinction is audience and philosophy, not raw feature count — Kit deliberately does creator email well rather than doing everything adequately.

On the other side are all-in-one creator platforms and newsletter tools such as Substack or Beehiiv, which bundle publishing, audience, and payments. The trade-off is ownership and flexibility. Substack, for instance, hosts your publication and audience on its platform and takes a cut of paid subscriptions; Kit is more of a toolkit you use to build and own your list, integrate with other tools, and control your monetization. A creator who wants a turnkey publication with a built-in discovery network might choose a hosted platform; one who wants to own the relationship and wire email into a wider business often prefers Kit. It is also distinct from a pure transactional email service — Kit sends marketing and relationship email to a list, not automated system messages triggered by software events.

Use Kit the way it is built to be used — as the home for an owned audience, not just a newsletter sender. Grow the list with forms and landing pages placed where your audience already meets you, then use tags to record what each subscriber cares about and automations to send relevant sequences instead of one-size-fits-all blasts. Welcome new subscribers with a genuine sequence, segment buyers from browsers, and reserve the hard sell for people who have signaled interest. If you monetize, lean on Kit's commerce and paid-subscription tools so the list and the earnings live in one place. Keep deliverability healthy by honoring unsubscribes promptly, keeping the list clean, and sending email people asked for — a creator's reputation is fragile, and inbox placement depends on it.

The failure modes are the usual email ones sharpened by the creator context. Treating Kit as a broadcast megaphone — mailing the whole list the same promo repeatedly — wastes its automation strengths and burns goodwill. Neglecting tags and segments means everyone gets everything, which trains subscribers to ignore you. Over-monetizing a list before you have earned trust drives unsubscribes. And on the practical side, remember the rebrand — do not let stale ConvertKit references confuse readers, and check that integrations you rely on support the current Kit branding and API. Used with restraint and good segmentation, Kit turns an audience into a durable, owned channel; used as a blast tool, it is just another way to annoy people who once liked your work.

Kit, formerly ConvertKit, is a creator-focused email marketing platform for newsletters, automations, landing pages, and monetization, rebranded from ConvertKit in 2024.
