Short answer: Mailchimp vs ConvertKit for small business depends on what your list is for. Pick Mailchimp if you send a simple newsletter to customers and want easy templates and clear reports. Pick ConvertKit if you are a creator, coach, or seller who builds a list to sell courses, products, or services. Both send email well, so the choice is about whether your list is a newsletter or a sales channel.
Mailchimp vs ConvertKit for small business at a glance
Mailchimp is built for the classic newsletter. You pick a template, add your news, and send it to your list. The builder is visual, the reports are clear, and a small business can send a good-looking email in an hour. It also has tools for ads and landing pages, so a shop can run a simple campaign in one place. That ease is why so many small businesses start here, and why many stay.
ConvertKit is built for creators who sell. It thinks in tags and sequences, not just lists. A subscriber who clicks a link gets a tag, and the next email they get depends on that tag. That sounds technical, but it is how a creator sells the right thing to the right person without spamming the whole list. The setup takes a day or two to learn, but once it clicks, the selling flow feels natural. If your list is your business, ConvertKit fits that job better.
| What matters | Mailchimp | ConvertKit |
|---|---|---|
| Best fit | Shop newsletter, simple news | Creator or coach who sells |
| Learning curve | Easy, familiar lists | A day to learn tags |
| Automation | Good for simple flows | Strong for sales flows |
| Templates | Many, easy to shape | Simple, clean, plain |
| Selling | Basic, through the shop | Built in, with funnels |
What sending an email feels like
In Mailchimp, sending is visual. You drag in a photo, add a headline, and the email looks like your shop. That matters for a business where the email is a shop window: a new product, a sale, a story. The templates are easy to shape, and the preview shows you how it will look on a phone. For a weekly newsletter, that flow is fast and calm, and your team can learn it in a day.
In ConvertKit, sending is plain on purpose. The emails look like a note from a person, not a flyer from a shop, and that plain style gets opened and read more by many creator audiences. You write the email, pick the tags it goes to, and send. There are fewer design choices, which can feel thin at first, but it keeps the focus on the words. If your emails sell through story and trust, that plain style is a plus, not a lack.
Your list is an asset, not a chore
Whichever tool you pick, treat the list like an asset. Clean it every few months, remove people who never open, and ask new subscribers what they want to hear about. A small, clean list that opens your emails is worth more than a large, stale list that ignores them. Both tools make cleaning easy, so the winner is the owner who does it, not the software.
Automation that actually sells
Automation is where ConvertKit pulls ahead for sellers. You can build a visual flow: a new subscriber gets a welcome series, a click on a link sends them to a sales series, and a purchase moves them to a customer series. Each step depends on what the person did, not on a fixed date. That flow sells while you sleep, and it does so without spamming people who are not interested. For a creator with a course or a product, that is the core job of the tool.
Mailchimp automation is good for simpler flows: a welcome email, a birthday note, a reminder about a left cart. Those flows matter for a shop, and they are easy to set up. The gap shows up when you want a sales flow that branches based on behavior. Mailchimp can do some of that, but the flow is less visual and less direct. If your automation is simple, either tool works. If it drives your sales, test ConvertKit with a real flow before you decide.

One more cost to count is your own time. A newsletter that takes four hours to build each week costs more than the tool itself, even on a free plan. Mailchimp templates can cut that time, because you reuse the same layout and just change the words and photos. ConvertKit plain emails can cut it too, because there is less design to fuss over. Pick the builder that lets you finish an email in under an hour, because a weekly email you actually send beats a beautiful email you never finish. Set a simple routine: same day each week, same layout, same length. Your readers will learn the rhythm, and you will stop dreading the send button. That routine is worth more than any feature on a pricing page.
Price, lists, and what growth costs
Check the current plan on their site for both, then count your subscribers, not just your team. Email tools charge by list size, so a growing list means a growing bill in either tool. Mailchimp can start low or free for a tiny list, then rise as the list grows. ConvertKit also rises with the list, and its paid plans add the automation that makes it worth the price. The math that matters is revenue per subscriber, not cost per month. If the list brings in sales, the tool pays for itself.
Also count the cost of a switch. Moving a list is simple, but rebuilding automations takes time, and a messy move can hurt deliverability. Pick the tool that fits where your list will be in a year, not just where it is today. If you plan to sell to the list, start with the seller's tool. If you plan to send news to customers, start with the newsletter tool. Our guide to small business software cost in 2026 shows how to add up the full year for a marketing stack.
Which one fits your business type
A shop, a restaurant, or a local service that sends weekly news fits Mailchimp. The templates look good, the reports are clear, and the team can send a campaign without a long learning curve. A creator, a coach, or a seller who builds a list to sell fits ConvertKit. The tags, the sequences, and the plain emails are built for that job, and the learning curve pays off in sales.
There is also a middle path: start with the simple tool, and move when your list starts to sell. Many owners do that, and it works, as long as you clean the list before you move it. Do not let the tool choice stop you from starting. A list that you email every week, even with a simple tool, beats a perfect tool with no list at all. Start with one real email a week, and let the list grow from there.
Mailchimp vs ConvertKit for small business: the pick for most US owners
Pick Mailchimp if your email is a newsletter for customers, and you want easy templates and fast sending. Pick ConvertKit if your email is a sales channel for a course, a product, or a service, and you want tags and sequences that sell. Both are good tools, so the wrong pick is not fatal. You can move the list later, and your subscribers will follow if you tell them clearly.
Try both with a real campaign, not a demo. Send a real email to a real segment, watch the opens and clicks, and see which builder your team enjoys.
