Mailchimp vs ConvertKit: Which Is Better for Your Email List?

The short version: Mailchimp is better for small businesses that want a familiar, visual tool with a generous free tier and e-commerce features baked in. ConvertKit (now rebranded as Kit) is better for creators, bloggers, and course sellers who need powerful automations and subscriber-centric tagging without wrestling a clunky interface. Neither is perfect, and the wrong choice will cost you real money and real time.

I have used both. Not in a casual "I poked around the free trial" way. I mean I have migrated lists between them, built automations in both, watched open rates shift, and sat in front of a screen at midnight wondering why a sequence was not triggering. I have opinions, and I am going to share them plainly.

If you are already sold on the idea that email is worth the effort, good. If you are still on the fence, read why email marketing is still the best thing you can do for your business first, then come back here. This post is for people who are ready to choose a tool.

A quick word on what both tools are in 2026

Mailchimp has been around since 2001. It was the first email marketing tool most people ever touched, partly because it had a free plan and a friendly chimp mascot. Intuit bought it in 2021 for $12 billion. Since then it has been expanding hard into CRM territory, adding landing pages, websites, paid ads management, and social scheduling. It is trying to be an all-in-one small business marketing platform.

ConvertKit rebranded to Kit in late 2023. The rebrand caused some confusion and a fair bit of eye-rolling in creator communities, but the product itself has continued to improve. It is squarely aimed at creators: writers, podcasters, YouTubers, course builders, coaches. Its whole philosophy is that you should be managing subscribers, not lists.

These two tools have different philosophies at their core. That matters more than any feature comparison table.

Pricing: what you pay

Let me give you the real numbers because most comparison articles either quote outdated pricing or bury it.

Mailchimp pricing in 2026

• Free plan: Up to 500 contacts, 1,000 sends per month. One audience only. Basic templates. No automations beyond a single welcome email.
• Essentials: From around $13 per month for 500 contacts. Removes Mailchimp branding, adds A/B testing, 3 audiences.
• Standard: From around $20 per month for 500 contacts. Adds the proper automation builder, retargeting ads, advanced analytics.
• Premium: From $350 per month. Multivariate testing, unlimited audiences, phone support. Most small businesses will never need this.

The catch with Mailchimp that nobody warns you about clearly: they charge you for unsubscribed contacts. If someone unsubscribes, they stay in your contact count until you manually archive them. I found this out the expensive way when I was paying for a list that was significantly inflated by people who had already left. Clean your list regularly or you will overpay.

ConvertKit (Kit) pricing in 2026

• Free plan: Up to 10,000 subscribers. Unlimited landing pages and forms. No automations. No paid newsletter features. Limited to one email sequence.
• Creator: From $25 per month for up to 1,000 subscribers. Full automation builder, integrations, free migration from another platform.
• Creator Pro: From $50 per month for up to 1,000 subscribers. Adds newsletter referral system, subscriber scoring, Facebook custom audiences, advanced reporting.

Kit's free plan is impressive at 10,000 subscribers. Mailchimp's caps you at 500. If you are just starting out and want to grow before paying, Kit wins that round easily.

But here is the thing about Kit's pricing as your list grows: it gets expensive fast. At 50,000 subscribers, Creator plan costs around $179 per month. At 100,000 subscribers you are looking at around $379 per month. Mailchimp Standard at the same list size is cheaper. So Kit is not the budget option at scale.

The interface: which one is easier to use

Mailchimp has a drag-and-drop email builder that most people find intuitive on day one. You can pick a template, slot in your logo, add some text, preview it, and send. It looks like what people expect an email builder to look like. The flip side is that the navigation is a mess. Features are buried, the audience management section is confusing, and when they redesigned the dashboard a few years back they moved everything around and broke muscle memory for long-term users.

Kit's editor is minimal. It defaults to a plain-text-style email because research consistently shows that plain text emails get higher engagement for creator-type content. You can add images and buttons, but it does not push you toward elaborate branded templates. Some people find this liberating. Others find it sparse and are not sure what to do with it.

For building automations specifically, Kit is considerably cleaner. The visual automation builder uses a simple flowchart layout. You can see an entire sequence at a glance. Mailchimp's automation builder (called Customer Journeys) is more powerful in some ways but it is also more cluttered and harder to read when a sequence gets complex.

List management and segmentation: the biggest real difference

This is where the two tools diverge, and it is the thing most comparison articles gloss over because it takes a bit of explanation.

Mailchimp is list-based. If the same subscriber is on two of your lists, they count as two contacts and you pay for both. You can segment within a list using groups and tags, but the core unit is the list (which Mailchimp now calls "audiences"). This model made sense in 2008. It makes less sense now when people expect personalised, behaviour-triggered emails.

Kit is subscriber-based. Every subscriber exists once in your account. You apply tags to them. You can have a subscriber tagged as "bought course A," "interested in SEO," and "came from podcast" all at once, and you can trigger different automations based on any combination of those tags. This is a fundamentally more flexible architecture for anyone sending more than one type of content.

I ran a real experiment on this. I was running a lead magnet campaign targeting two different audiences: UK small business owners and US freelancers. In Mailchimp I had them in separate audiences and ended up duplicating every automation. When I moved to Kit, I had everyone in one place with tags and the whole operation took half the time to manage. The time saving was not small. It was probably three hours a week.

Automations: who does it better

Both tools have automation. The quality of that automation is different.

Mailchimp's Customer Journeys builder allows you to create multi-step journeys based on triggers like sign-ups, purchases, email activity, and date-based events. It is solid for e-commerce sequences. You can pull in product recommendation blocks and connect it to a Shopify or WooCommerce store in a way that Kit cannot match out of the box.

Kit's automations are more flexible for content-based triggers. You can automate based on: subscriber clicks a specific link, subscriber is tagged, subscriber completes a sequence, subscriber purchases a specific product. The logic is cleaner. You can also build visual funnels that branch based on subscriber behaviour without things getting visually chaotic.

For an e-commerce business sending cart abandonment emails and post-purchase sequences, Mailchimp is probably the better choice. For a coach or course creator sending onboarding sequences that branch depending on which lead magnet someone downloaded, Kit is the better choice.

Deliverability: the honest picture

Both Mailchimp and Kit have good deliverability. I am not going to pretend one magically lands in the inbox more than the other because the real variables are your list hygiene, your sending frequency, your subject lines, and your engagement rates. A clean list on either platform will perform well. A cold or dirty list on either platform will not.

One honest point most articles will not make: Kit's default to plain-text-style emails is a deliverability advantage for certain types of content. Plain text emails are less likely to be flagged as promotional by Gmail's tabs system. When I switched a newsletter from a heavily branded Mailchimp template to a plain-text-style Kit email, open rates went up by about 8 percentage points over four weeks. That is a meaningful number. Whether that was the template, the new platform, or just natural list variation, I cannot say with certainty. But I have seen similar results reported by others.

E-commerce features: Mailchimp's real advantage

If you sell physical products, Mailchimp is meaningfully better integrated into the e-commerce world. It connects directly to Shopify, WooCommerce, BigCommerce, Magento, and more. You get abandoned cart sequences, product recommendation blocks that pull from your actual store inventory, purchase-triggered automations, and revenue reporting that shows you exactly how much money each email generated.

Kit does have a native commerce feature that lets you sell digital products and subscriptions directly. But for physical product sellers with existing stores, the Mailchimp integrations are deeper and more battle-tested.

Creator features: Kit's real advantage

Kit was built with creators in mind and it shows. The paid newsletter feature (called Kit Paid Newsletters) lets you charge subscribers directly for content, with Stripe integration and automatic access management. The referral system in the Creator Pro plan lets subscribers share your newsletter and earn rewards, which is a real growth tool that Mailchimp simply does not have a native equivalent for.

Kit also has a creator network feature where you can recommend other newsletters and be recommended in return. For newsletter operators trying to grow an audience, this is valuable. Mailchimp has nothing comparable.

If you are building a paid newsletter, a course business, or a coaching practice, Kit is built for exactly that use case in a way that Mailchimp is not.

A real story: the migration that taught me something important

A few years back I was helping a client who ran a business education blog. She had around 8,000 subscribers on Mailchimp, was paying about $99 a month, and was frustrated because her automations were getting complicated to manage and her open rates had stalled at around 19%.

We moved her to Kit. The migration took one afternoon, not because it was technically hard but because we took the time to clean the list first, removing anyone who had not opened an email in 12 months. That cut the list from 8,000 to 5,400. Her monthly cost on Kit Creator went from $99 on Mailchimp to $79 on Kit for that list size.

Within six weeks her open rate had climbed to 27%. Now, the platform change was not the only variable. We also rewrote her subject lines and changed her sending day from Monday to Thursday. But the cleaner list and the more targeted sequencing that Kit made easier were real contributors.

The thing that struck me was how much easier it was to see what was working. Kit's reporting is not as visually fancy as Mailchimp's, but the data you care about is right there on the first screen. With Mailchimp she had been clicking through four or five menus to find her click rate by segment. With Kit it was one click.

For anyone interested in going deeper on how niche content businesses can get more from email, I wrote about exactly that in my post on how niche businesses can use email marketing to reach the right customers.

Forms and landing pages

Both tools let you build opt-in forms and landing pages without needing a separate tool.

Kit's landing pages are cleaner and faster to build. There are fewer templates but the ones that exist convert well. You can have a landing page live in under ten minutes. Kit also allows unlimited landing pages and forms on the free plan, which is a significant advantage if you are running multiple lead magnets.

Mailchimp's landing page builder is more flexible in terms of design options but slower to use. The form builder is functional but not elegant. If you are already paying for a landing page tool separately, this matters less. If you want everything in one place for free or cheap, Kit wins.

Reporting and analytics

Mailchimp's reporting is visually richer. You get click maps that show you where in the email people were clicking, e-commerce revenue attribution, social performance stats, and comparative campaign reporting. For someone who loves data and wants to dig into it, Mailchimp gives you more to work with.

Kit's reporting is simpler. You see opens, clicks, unsubscribes, and revenue from your products. The automation reports show you where subscribers are dropping off in a sequence. It is not as comprehensive but it is not trying to be. For most creators and small business owners, it is enough.

If reporting and analytics are critical to your decisions, Mailchimp has the edge. If you just want to know what is working without getting lost in dashboards, Kit is fine.

Customer support

Mailchimp offers email support on paid plans and chat support on Standard and above. Phone support only on Premium. Their help documentation is extensive and generally accurate. Wait times on chat can be frustrating.

Kit offers email support on all plans including free, and live chat on paid plans. Their support team has a good reputation for being responsive. They also have a strong community and active user forums.

Neither is exceptional. Both are adequate. I would not choose a platform based on support alone.

Integrations

Mailchimp integrates with over 300 tools. It connects to most major e-commerce platforms, CRMs, social platforms, and lead generation tools. If you have an existing tech stack, there is likely a native Mailchimp integration.

Kit integrates with around 90 tools natively, with many more available through Zapier. The depth of those integrations varies. For creators whose stack is relatively simple (a website, a course platform, maybe a webinar tool), Kit's integrations are sufficient. For complex multi-tool businesses, Mailchimp's broader integration library is an advantage.

The honest point most articles will not make

Here it is: the tool you will use consistently is better than the tool that is technically superior on paper.

Most comparisons focus on features. Very few ask: which one will you sit down with on a Tuesday afternoon when you are tired and you just need to send a campaign? Which one will not make you feel like you need a tutorial every time you try to do something slightly different?

I have watched people choose Mailchimp because it has more features, build two automations, get frustrated with the interface, and then not touch their email marketing for four months. I have watched people choose Kit because it felt simpler, build a five-step welcome sequence in an afternoon, and send consistently every week because it did not feel like a chore.

Consistent, decent emails beat sporadic, perfect ones every single time. Choose the platform that reduces the friction between you and hitting send.

If you want to explore what else is out there before committing, I have a full breakdown of the best Mailchimp alternatives in 2026 that covers tools beyond just these two. And if Kit specifically interests you for blogging, I have a more focused piece on whether ConvertKit is the best email marketing tool for bloggers.

Who should choose Mailchimp

• You run an e-commerce store and want deep integration with Shopify or WooCommerce
• You want visual, branded email templates without much effort
• You are a small business that needs CRM-lite features alongside email
• Your list is larger and you want cheaper per-subscriber pricing at scale
• You need multivariate testing or advanced analytics
• You want a wider range of integrations with your existing tools

Who should choose ConvertKit (Kit)

• You are a blogger, podcaster, YouTuber, coach, or course creator
• You want a paid newsletter with subscriber management baked in
• You are starting out and want a serious free plan that scales to 10,000 subscribers
• You want clean automations that are easy to build and read
• You are happy with plain or lightly designed emails
• You want a subscriber-centric tagging system instead of managing multiple lists

My actual recommendation

If you are a creator, blogger, coach, or course builder: use Kit. The free plan is generous enough to validate your newsletter before spending anything, and the automation logic will serve you well as you grow.

If you sell physical products online or you are a small business with a mixed marketing stack that needs a tool connecting to your store, your social ads, and your CRM: use Mailchimp Standard at minimum.

If you are somewhere in the middle, start with Kit's free plan. The migration cost if you decide to switch later is low, and you will learn a lot about your list in the process. You can find a proper foundation for any of this in the complete guide to email marketing, which covers strategy before you even think about picking a tool.

Both platforms have improved significantly over the last two years. Neither is a bad choice if you choose the right one for your use case and you use it. The worst choice is spending three months comparing them and sending nothing.

Frequently asked questions

Can I switch from Mailchimp to ConvertKit without losing my subscribers?

Yes. You export your Mailchimp list as a CSV file, clean it before importing (remove unsubscribes, hard bounces, and cold subscribers), then import into Kit with whatever tags you want to apply. Kit offers free migration assistance on paid plans. The technical process takes a few hours; the list cleaning is what takes real time and thought.

Is ConvertKit (Kit) really free for up to 10,000 subscribers?

Yes, but with meaningful limits. The free plan allows up to 10,000 subscribers and gives you unlimited landing pages and forms, but you cannot build automations (beyond one sequence), you cannot send broadcast emails to paid subscribers, and you get Kit branding on forms. For a newsletter just starting out, it is useful. For anyone wanting to run automated sequences or monetise directly, you need a paid plan.

Does Mailchimp really charge for unsubscribed contacts?

Yes, unless you archive them. When someone unsubscribes in Mailchimp, they move to "unsubscribed" status but they stay in your contact count and you continue paying for them. You need to manually archive unsubscribed and cleaned contacts to remove them from your billable count. This is one of Mailchimp's most complained-about billing quirks and it is easy to miss.

Which is better for open rates: Mailchimp or ConvertKit?

Neither platform inherently guarantees better open rates. The variables that matter most are list quality, subject line, sending frequency, and relevance to your audience. That said, Kit's default plain-text email style is less likely to be sorted into Gmail's Promotions tab than heavily designed Mailchimp templates, which can give a deliverability edge for content-style newsletters. Clean lists on either platform consistently outperform bloated lists on either platform.
