Paid traffic is rented; an email list is owned. Kit (formerly ConvertKit) is an email marketing and automation platform built for creators and marketers who want to turn audiences into a durable asset. In this review we cover what it does, pricing, the pros and cons, who it’s for, and the alternatives.

What Kit does

Kit lets you capture subscribers with forms and landing pages, segment them with tags, and nurture them through automated email sequences. It’s designed to be approachable — you can build a welcome sequence or a broadcast without a steep technical learning curve — while still offering the automation depth that growing businesses need.

The platform leans toward creators and marketers who send a lot of content-driven email, with a clean editor and a tagging model that keeps your list organised as it grows.

Why pair it with paid media

When you stop paying, paid traffic stops. Capturing those visitors as email subscribers changes the economics: you can reach them again and again at no extra cost per send. A paid click that becomes a subscriber can be nurtured toward a purchase over weeks, not seconds — dramatically improving the return on your ad spend.

This is the owned channel that sits underneath the whole marketing funnel, and it’s what makes scaling paid campaigns sustainable rather than a treadmill.

Pricing

Kit offers a free plan for getting started, with paid tiers that scale by subscriber count and unlock advanced automation and integrations. Pricing changes over time, so check current plans on the Kit page. The free tier is a genuine way to start building a list before you commit budget.

Pros and cons

• Pro: Free plan to start, with room to scale as your list grows.
• Pro: Approachable automation and a clean, tag-based subscriber model.
• Pro: Strong fit for content-led, creator-style marketing.
• Con: Less suited to complex e-commerce flows than some rivals.
• Con: Design flexibility is simpler than heavier enterprise tools.
• Con: Costs rise as your subscriber count climbs.

Who it’s for (and who it isn’t)

Kit suits creators, marketers and small businesses who build audiences through content and want straightforward automation to nurture them. If turning paid and organic traffic into a long-term email relationship is your goal, it’s a natural fit.

It’s less ideal for large e-commerce operations needing deep product-based automation, where a platform built around a store may serve better.

Alternatives to consider

Mailchimp is broad and beginner-friendly; ActiveCampaign offers deeper automation; Klaviyo specialises in e-commerce. Kit’s strength is the creator-focused, content-first approach with automation that stays approachable as you grow.

Our verdict

If you want your ad spend to keep paying off long after the campaign ends, an owned email list is the answer — and Kit makes building one approachable. Start free and grow from there via the Kit page.
