What Kit Actually Is (From Someone Sending To A List Every Week)
I have run a niche newsletter through Kit (it was still called ConvertKit when I signed up) for about three years. It is currently my main income channel, so this is written from the sender's chair, not the pricing page.
Kit is an email marketing platform built for one specific type of person: the creator who wants to grow an audience and sell to it. It was rebranded from ConvertKit to Kit in October 2024. Same product, shorter name. The philosophy has not changed - plain-looking emails, obsessive deliverability, and automations that do the selling while you write.
The Money Angle: Why Email Beats Every Other Channel
Here is the blunt truth I learned the expensive way: social media followers are rented. Email subscribers are owned. My open rates on Instagram posts sit around 8%. My newsletter opens sit between 45 and 55%. When I send a product launch email, it makes sales the same day.
The standard playbook that works with Kit:
- Pick a niche problem people pay to solve (budgeting for freelancers, meal prep for shift workers, whatever you actually know).
- Build the list free with Kit landing pages and a simple lead magnet - all at $0 until 10,000 subscribers.
- Write one welcome sequence that teaches, then sells your product or affiliate picks.
- Sell digital products directly inside Kit - templates, ebooks, mini-courses. Kit handles checkout and delivery, takes 3.5% + 30Β’ per sale.
- Add a paid subscription tier once the free content proves demand.
People run six-figure businesses on exactly this loop. The tool matters less than the loop, but Kit removes every technical excuse for not building it.
What It Really Costs
The free plan is the headline and it is real: up to 10,000 subscribers, unlimited emails, unlimited landing pages and forms, and you can sell products on it. Mailchimp starts charging you before you hit 500 subscribers. That gap is why Kit dominates the creator space.
But read the fine print before you build your whole funnel on Free:
| Plan | Monthly Price | Yearly Price | What You Get / Lose |
|---|---|---|---|
| Newsletter (Free) | $0 | $0 | 10k subs, unlimited sends, but only 1 automation, no integrations, Kit branding |
| Creator | $39/mo (1k subs) | $33/mo | Unlimited automations and sequences, integrations, no branding |
| Creator Pro | $79/mo (1k subs) | $66/mo | Engagement scoring, referral system, unlimited users |
The trap is list-size scaling. Creator is $39/mo at 1,000 subscribers but $139/mo at 10,000, $199/mo at 25,000, and $679/mo at 105,000. Pricing is charged per subscriber whether they open your emails or not. If your list is full of dead weight, you are paying for it monthly - clean it or segment it.
The 3.5% + 30Β’ commerce fee is fine early on. Once you are selling $2,000+ a month of digital products, moving checkout to Lemon Squeezy or Polar and using Kit purely for email math makes more sense.
Kit vs The Field
| Tool | Free Limit | Automations | Built-in Product Sales | Best For |
|---|---|---|---|---|
| Kit | 10,000 subs | 1 on free, unlimited paid | Yes (3.5% + 30Β’) | Creators selling to a list |
| beehiiv | 2,500 subs | Limited on free | Paid subscriptions | Ad-funded newsletters |
| Mailchimp | 500 contacts | Basic | No | Small businesses, pretty templates |
| MailerLite | 1,000 subs | Generous | Yes | Budget option at scale |
If your model is "newsletter with sponsorships," beehiiv's ad network will out-earn Kit. If your model is "audience that buys my stuff," Kit's commerce and automation depth wins. I have used both; Kit is where my actual revenue lives.
Bottom Line
Kit is the best free deal in the creator economy right now, and I do not say that lightly. A ten-thousand-subscriber free tier with product sales included means the cost of starting an email business is literally zero dollars. The honest warning: paid tiers get pricey as your list grows, the design tools are plain on purpose, and one automation on the free plan will annoy you the moment you want a real funnel. Start free, prove the loop works, upgrade when revenue justifies the $33 to $39. That is the whole decision.
