ConvertKit vs Mailchimp for Bloggers: The 2025 Truth
Mailchimp is famous. ConvertKit is built for creators. After sending thousands of emails on both platforms, here is which one actually performs better for bloggers.
Most bloggers start with Mailchimp because it is free and everyone has heard of it. Many of them switch to ConvertKit eventually. Understanding why might save you the time and disruption of migrating your list later.
Who they are built for
Mailchimp was built for small businesses sending promotional emails — think a local coffee shop sending a monthly newsletter. It works perfectly well for this. ConvertKit was built specifically for creators: bloggers, podcasters, YouTubers, and course creators who want to build an audience relationship, not just send broadcasts.
The subscriber model difference
This is the most important difference that review articles often gloss over. Mailchimp organises your subscribers into lists. If the same person is on two lists, they count as two subscribers and you pay for them twice. ConvertKit organises by tags and segments — one subscriber can have multiple tags and you only pay for them once. For bloggers building a single audience, the ConvertKit model is significantly cheaper as your list grows.
Automation
ConvertKit has better automation for content creators. The visual automation builder is intuitive and designed around sequences — welcome sequences, course drip sequences, nurture sequences. Mailchimp has more automation options in theory but they are harder to configure correctly and the interface is less intuitive.
Landing pages and forms
Both include landing page builders. ConvertKit forms are simpler and convert very well partly because of their simplicity. Mailchimp has more templates and customisation options but this rarely translates to better conversions in practice.
Free tier comparison
Mailchimp free: up to 500 subscribers, 1,000 sends per month, basic features. ConvertKit free: up to 10,000 subscribers, unlimited sends, landing pages and forms — but no automations. For a blogger just starting out, ConvertKit free is the better starting point because the subscriber limit is much higher.
The migration problem
If you start with Mailchimp and later switch to ConvertKit, you will need to migrate your list, rebuild your automations, and update your signup forms across your site. It takes a weekend and is annoying. If you know you are building a content-first audience, just start with ConvertKit.
Our recommendation
Start with ConvertKit if you are building a blog, newsletter, or any content-driven audience. The free tier is generous enough to get started, the platform grows with you, and you will not need to migrate later. Use Mailchimp if you are running a small business with a retail or service focus and primarily want to send promotional emails.
