MailerLite vs ConvertKit: Which Email Tool for Your Growth Stage?

MailerLite and ConvertKit are both built for independent creators and small businesses. They overlap significantly — both offer email automation, landing pages, forms, and segmentation. The difference is where each platform has put its investment: MailerLite in value and usability, ConvertKit in the creator ecosystem and commerce layer.

For most people starting out, this decision comes down to: do you need to sell directly through your email platform, or do you primarily need to build and nurture a list?

Short version: MailerLite wins on value — more features at lower cost, genuinely good free tier. ConvertKit wins if you’re selling products through email or want access to the creator sponsorship network. For pure newsletter growth, MailerLite is usually the smarter starting point.

Quick Comparison

MailerLite — Best Value for Newsletter Builders

MailerLite’s free plan is genuinely useful: 1,000 subscribers, 12,000 emails per month, automation workflows, landing pages, signup forms, and segmentation. Most platforms either cap automation or landing pages at the free tier — MailerLite includes both.

What MailerLite does well:

Interface. MailerLite has one of the cleaner email builder experiences in the category. The drag-and-drop editor works without fighting it. Email previews are accurate. The template library covers most use cases without feeling generic.

Automation. The workflow builder handles the standard sequences well: welcome series, lead magnet delivery, re-engagement campaigns, tag-based segmentation. Nothing exotic, but the common patterns are smooth to set up.

Website builder is included — a simple but functional tool for landing pages and basic sites. Useful if you don’t want to manage a separate landing page tool. For a more complete site, you’d want something dedicated, but for lead capture pages it works.

Forms and pop-ups. Embedding forms, triggering pop-ups based on scroll or exit intent, and routing form submissions into specific automations all work without code.

Pricing: Free up to 1,000 subscribers. $9/month (Growing Business) at 1-500 subs, scaling by subscriber count. Competitive at every tier — roughly 60% cheaper than ConvertKit at equivalent subscriber counts.

Limitation: The creator ecosystem doesn’t exist. No sponsorship marketplace, no cross-promotion network, no built-in product commerce. MailerLite is a list-building and nurturing tool, not a creator monetization platform.

ConvertKit — Best for Selling Through Email

ConvertKit is built around the idea that your email list is a business asset you sell through. The platform reflects this: tagging, segmentation, and automation are designed around purchase behavior. The commerce layer handles digital product sales natively. And the Creator Network connects you with other creators for cross-promotion and sponsorship.

What ConvertKit does well:

ConvertKit Commerce. Sell digital products, courses, and subscriptions directly through ConvertKit — no Gumroad or external payment processor needed. The checkout experience is clean and the integration with your email list is native. If you’re selling a $49 ebook or a $197 course, ConvertKit Commerce handles it with no additional tools.

Tagging and segmentation. ConvertKit’s subscriber management is sophisticated — tag based on links clicked, products purchased, forms submitted, and custom events. This matters when you’re sending different offers to different segments and need the targeting to be precise.

Creator Network. A built-in directory where subscribers discover new newsletters and creators can cross-promote each other. Useful for growing your list through recommendation networks. This doesn’t exist in MailerLite.

Sponsorship marketplace. ConvertKit connects creators with brands for paid newsletter sponsorships. Available once you have a meaningful subscriber count, but valuable as a monetization path.

Pricing: Free up to 10,000 subscribers, but automation, sequences, and integrations require the Creator plan at $25/month (up to 1,000 subs) — the free tier is more limited than it appears. At 5,000 subscribers, Creator plan runs $66/month.

Limitation: The price gap versus MailerLite is significant. At 5,000 subscribers, you’re paying $47/month more for ConvertKit’s Creator plan. If you’re not using Commerce or the Creator Network, that premium is hard to justify.

Head-to-Head on Key Decisions

Building a newsletter from scratch

MailerLite. Lower cost, better free tier, comparable automation. Start here and migrate if you outgrow it.

Selling digital products via email

ConvertKit. Commerce integration is native and well-built. Worth the price if you’re actively selling.

Automation and sequences

Tie. Both platforms handle standard email sequences, tag-based routing, and behavioral triggers. ConvertKit’s interface is slightly more visual; MailerLite’s is slightly more intuitive.

Growing through cross-promotion

ConvertKit. The Creator Network and sponsorship marketplace don’t have a MailerLite equivalent.

Budget under $20/month

MailerLite. Not close — MailerLite’s $9/month Growing Business plan vs ConvertKit’s $25/month minimum is a meaningful difference for early-stage creators.

The Migration Question

If you start on MailerLite and later decide ConvertKit is right, the migration is straightforward: export your subscribers as CSV, import into ConvertKit, rebuild your automations. The main cost is time rebuilding your sequences — usually 2-4 hours for a standard setup. Both platforms maintain this process.

The practical implication: start where the value is now, not where you might be in three years. MailerLite at 500 subscribers costs $9/month. ConvertKit at 500 subscribers costs $25/month. If you’re not actively using the ConvertKit-specific features (Commerce, Creator Network), you’re paying $192/year for brand perception.

Our Pick

Starting out, primary goal is list-building and newsletters: MailerLite. The free tier is genuinely useful, the paid tiers are priced fairly, and the feature set covers everything most creators need.

Actively selling digital products or courses: ConvertKit. The native commerce layer and creator ecosystem are worth the price premium if you’re using them.

Both integrate with most tools you’re already using — Notion, project management tools, Zapier, and most course platforms. The choice comes down to your monetization model, not technical integration.
