Email marketing isn't sexy. Nobody gets excited about open rates and subject lines the way they do about TikTok views or Instagram reels. But here's the thing: email marketing still delivers the highest ROI of any digital marketing channel. The numbers aren't even close. For every dollar spent on email marketing, the average return is somewhere around $36-$42 depending on whose research you trust.
That's not a typo. And it's why every serious online business, from solo creators to Fortune 500 companies, still treats email as the backbone of their marketing.
Mailchimp: The Name Everyone Knows
Mailchimp has been the default email marketing platform for over a decade. It's the one your friend who started a blog in 2015 used. It's the one your local bakery uses. And despite some controversial changes over the years (RIP the generous free plan), it's still a solid platform.
The free plan now allows 500 contacts and 1,000 sends per month. That's tight, but it's enough to test the waters. The Essentials plan starts at $13/month for 500 contacts and scales up from there. The Standard plan at $20/month adds automation, A/B testing, and better analytics.
Mailchimp's biggest strength is its ecosystem. It integrates with practically everything: Shopify, WordPress, Squarespace, Canva, social media platforms, CRMs. If you use a tool, Mailchimp probably connects to it.
The drag-and-drop email builder is excellent. Templates look professional. The automation builder handles welcome sequences, abandoned cart emails, and follow-up series without much technical knowledge.
Kit (Formerly ConvertKit): Built for Creators
Kit took a different approach. Instead of trying to be everything for everyone, it built the best email platform for creators: bloggers, YouTubers, podcasters, course creators, and newsletter writers. And it shows in every design decision.
The free plan supports up to 10,000 subscribers (yes, ten thousand) with basic features. The Creator plan starts at $25/month for up to 1,000 subscribers and adds automation, integrations, and premium support. The Creator Pro plan at $50/month adds advanced reporting and subscriber scoring.
Kit's automation is its superpower. The visual automation builder is intuitive and powerful. You can create complex sequences based on subscriber behavior, tags, purchases, and more. The logic feels natural, not like you're programming a machine.
The email editor is intentionally simple. Kit believes that plain-text-style emails perform better for creators (and they're right for most use cases). If you want gorgeous, image-heavy marketing emails, Mailchimp is better. If you want emails that feel like a personal message from a real person, Kit nails it.
Head to Head: Where Each Wins
Ease of getting started: Mailchimp. The setup process is straightforward, the templates get you designing immediately, and the interface is familiar even if you've never used it.
Automation: Kit. The visual automation builder is cleaner, more powerful, and easier to understand. Mailchimp's automation works fine, but Kit's feels like it was the first thing they built, not an afterthought.
Design flexibility: Mailchimp. More templates, more design options, more visual control. If your brand relies on beautiful emails with lots of images and design elements, Mailchimp gives you more to work with.
Subscriber management: Kit. The tag-based system is more flexible than Mailchimp's list-based approach. In Mailchimp, a subscriber on three lists counts as three subscribers (and you pay three times). Kit uses tags, so one subscriber with multiple tags counts once.
Landing pages: Kit. Built-in landing pages and opt-in forms that look great and convert well. Mailchimp has landing pages too, but Kit's feel more polished for creator use cases.
E-commerce integration: Mailchimp. Deeper integration with Shopify, WooCommerce, and other e-commerce platforms. Better product recommendation features and purchase-based automation.
The Real Decision
If you run an e-commerce business, a local business, or need visually rich marketing emails, go with Mailchimp. It's the more versatile platform with broader integration support.
If you're a creator, blogger, course seller, or anyone whose business is built on a personal audience, Kit is the better fit. The subscriber management is smarter, the automation is more intuitive, and the whole platform is designed for how creators actually work.
Both platforms will send your emails reliably. Both have good deliverability. Both will grow with you. The question is which one matches how you think about your audience and your content. Start with a free plan on both, send a few emails, and you'll know which one feels right within a week.
One more option worth considering before you decide: beehiiv. It's not a direct replacement for either platform — it's purpose-built for newsletter publishing specifically, with native paid subscriptions, a referral program, and a built-in ad network. If growing a monetized newsletter is your primary goal rather than general email marketing, it's worth a look.
