Kit (ConvertKit)

What is Kit (ConvertKit)?

Kit — formerly ConvertKit — is an email marketing platform built specifically for creators who sell digital products. Founded in 2013 by Nathan Barry in Boise, Idaho, the company grew to approximately $40 million in annual recurring revenue by 2024 without venture capital. In 2024, Nathan Barry rebranded the product from ConvertKit to Kit to reflect its evolution into a full creator operating system covering email, commerce, and cross-promotion.

Kit’s core differentiation is the combination of a mature visual automation builder and a built-in commerce layer. Most email platforms focus on broadcast newsletters. Kit focuses on subscriber journeys — the sequence of emails, triggers, and product offers that turn a new subscriber into a paying customer. That focus makes it the default recommendation for bloggers, course creators, and coaches who need email marketing and product selling in one system.

Kit fits squarely in the 80/20 of newsletter tools for creators with an existing product or strong intent to build one.

How does Kit work?

Kit runs on three systems: subscriber management via tags and segments, email automation via a visual builder, and product commerce via Kit Commerce. The three systems connect — a tag triggers an automation, an automation sells a product, a product purchase triggers another tag. Understanding how they interlock explains why Kit is the default for creator funnels.

Tag-based subscriber management

Kit’s subscriber model is tag-based, not list-based. One subscriber can have ten tags and appear in ten different segments without being charged twice. Mailchimp charges per subscriber per list — so a person on three lists costs three times more. Kit’s model costs less at scale and keeps subscriber data cleaner.

Writers use tags to track subscriber behavior: clicked a link, downloaded a lead magnet, purchased a product, attended a webinar. Those tags trigger automations automatically. The system replaces Zapier for most creator workflows that connect email behavior to product delivery.

Visual automation builder

The automation builder is Kit’s most powerful feature and its clearest advantage over Beehiiv and Substack. Writers draw multi-branch sequences visually — send email A, wait three days, if subscriber opens, tag them and send email B, if not, send email C with a different angle.

These automations run for every new subscriber who matches the entry condition, making them the backbone of course launch sequences, evergreen product funnels, and onboarding flows. A typical creator has three to eight live automations running simultaneously across different subscriber segments.

Kit Commerce and product selling

Kit Commerce processes payments, delivers digital files, and triggers email sequences from purchases without a third-party cart. Writers create product listings in Kit, set prices, and connect to Stripe. When a subscriber buys, Kit fires the delivery email, updates their tags, and starts any associated automation.

Kit takes 3.5% plus $0.30 per transaction through Commerce. This fee is higher than Stripe alone (2.9% + $0.30) but lower than platforms like Gumroad that take 10% to 14%.

How does Kit compare to Beehiiv and Mailchimp?

Kit wins on automations and commerce depth. Beehiiv wins on email design, analytics, and ad monetization. Mailchimp wins on template variety and e-commerce brand integrations. The correct pick depends on whether automation and product selling or broadcast design and analytics is your primary need.

Visual automations	Best in class	Basic	Strong
Built-in commerce	Yes (Kit Commerce)	No	Limited
Free tier	Up to 10,000 subs	Up to 2,500 subs	Up to 500 contacts

Analytics	Functional	Advanced	Advanced

Starting paid price	$25/month	$42/month	$20/month

“Kit is the clear choice for anyone building a product business on top of their newsletter — the visual automations and built-in commerce mean you’re not duct-taping Stripe, Zapier, and a separate email platform together,” said Marcus Reed, Go-to-Market Editor at tools8020.

Who uses Kit in 2026?

Kit’s typical users are bloggers, course creators, coaches, and authors with an email-first business model. Pat Flynn (Smart Passive Income), Tim Ferriss’s newsletter team, and thousands of independent course creators use the platform. The Creator Network cross-promotion feature means Kit users actively recommend each other at newsletter signup, creating an organic discovery loop inside the Kit ecosystem.

The platform hosts several newsletters exceeding 100,000 subscribers. At that scale, the tag-based billing becomes a significant advantage — Mailchimp users with the same subscriber count pay substantially more because the same person on multiple segments is counted multiple times. Kit’s model avoids that problem entirely.

Kit also has a disproportionate presence among podcasters and YouTube creators who use email as the primary owned-media channel. These creators often have large audiences on rented platforms and use Kit automations to convert followers to email subscribers — then sell courses, coaching, or memberships directly from those sequences. The combination of Creator Network cross-promotion and Kit Commerce eliminates the need for three separate tools to manage discovery, email, and transactions.

When should you skip Kit?

Kit is the wrong choice in three situations. Choose the alternative below before defaulting to Kit.

• You want Substack’s built-in reader network. Kit has the Creator Network for cross-promotion, but it does not have Substack’s dedicated reader app with social following. For discovery-led newsletter growth, Substack is the stronger platform.
• You need advanced email design. Kit’s email editor is functional but visually dated. Beehiiv’s editor produces more polished newsletters with better mobile rendering. If your newsletter is highly visual or heavily branded, Beehiiv fits better.
• You run a pure e-commerce brand. Kit is built for creator funnels, not product catalogs. Klaviyo is the correct choice for Shopify or WooCommerce stores with large product lines and complex segmentation by purchase history.

How much does Kit cost?

Kit is free for up to 10,000 subscribers with unlimited email sends and landing pages. Paid plans start at $25 per month for the Creator plan at 1,000 subscribers. Pricing scales by subscriber count — a list of 25,000 subscribers costs $100 per month on the Creator plan.

Plan	Price	Subscribers	Key limit
Free	$0	Up to 10,000	1 automation, no Creator Network
Creator	$25–$100/month	1,000–25,000	Unlimited automations, Creator Network
Creator Pro	$50–$200/month	1,000–25,000	Advanced reporting, subscriber scoring
25,000+	Custom	25,000+	Dedicated account management

Pricing verified at kit.com/pricing on 2026-05-24. Kit runs frequent promotional discounts — the list price is the ceiling, not always the actual entry price for new accounts.

How we evaluated Kit

This review draws on Marcus Reed’s direct use of Kit (then ConvertKit) across three creator businesses from 2021 to 2026, covering list sizes from 500 to 45,000 subscribers. We tested the automation builder, Kit Commerce, Creator Network, and deliverability across major email clients.
