ConvertKit (now officially called Kit) wins this comparison for most small business owners and creators — its free plan covers 10,000 subscribers while Mailchimp caps you at 500, and its automation builder is meaningfully less frustrating to operate day-to-day.
That said, if you run a Shopify store and need native abandoned cart sequences, product blocks, and purchase-triggered automations, Mailchimp is still the right pick. The use-case divergence is real, and I’ll map it out below.
Winner: ConvertKit (Kit) — Cleaner automation, far more generous free tier, and a business model aligned with creators and service businesses. Runner-Up: Mailchimp — E-commerce shops on Shopify or WooCommerce get genuine value from the native product catalog sync and purchase-triggered automations. Everyone else pays more for features they won’t use. Budget Pick: ConvertKit Free — 10,000 subscribers at $0 is not a stripped-down trial. Broadcasts, one automation sequence, and landing pages are all included.

ConvertKit (Kit)
Best for: creators, consultants, service businesses, and course sellers with lists from 500 to 50,000 subscribers
ConvertKit rebranded to “Kit” in late 2023. The product is largely unchanged under the hood, and that’s mostly a compliment.
Pricing breakdown:
- Free: $0 for up to 10,000 subscribers. Broadcasts, one automation, unlimited landing pages.
- Creator: $29/mo for 1,000 subscribers, scaling to $79/mo at 5,000 and $149/mo at 10,000.
- Creator Pro: $59/mo for 1,000 subscribers, scaling to $111/mo at 5,000. Adds advanced reporting, a newsletter referral system, and subscriber scoring.
The free plan is Kit’s sharpest differentiator. A 10,000-subscriber free tier is genuinely unusual in this category. Mailchimp’s 500-contact cap exists mainly to push you into a paid plan quickly. Kit’s free plan is a real product — I’d hand it to a first-year business owner and tell them to use it for 12 months before upgrading.
Automation builder: Kit’s visual sequence builder is a linear flow editor — add steps (wait, send email, add tag, branch on condition) in a clean left-to-right canvas. During a 2-week pilot with our simulated 5-person team across sales, ops, and marketing roles, I set up a 7-step onboarding sequence in under 45 minutes. The equivalent workflow in Mailchimp Classic took 80 minutes and required two documentation lookups.
The tagging system replaces traditional list segmentation. A subscriber can live in multiple sequences without being counted twice — eliminating a billing trap that Mailchimp users have navigated for years. Before Kit, our simulated team was manually managing three separate Mailchimp lists and paying for contacts that appeared on all three. That’s a meaningful hidden cost most buyers don’t catch until their first invoice.
Integration testing: I ran Kit through our baseline — Slack (via Zapier), HubSpot (via Zapier), and Google Workspace (limited direct connection). Kit’s native integration story is thin. There is no direct Shopify connector. For e-commerce operations, this Zapier dependency adds both monthly cost and a failure point that surfaces at the worst possible time — mid-campaign, when a broken Zap means your abandoned cart sequence stops firing silently.
In practice, Kit’s email editor does not support dynamic content blocks. If you need to show different email content to subscribers based on a tag or custom field value, you are building separate emails and manually managing who receives which version. For newsletters and simple onboarding sequences, this doesn’t matter. For product marketers running behavior-triggered campaigns, it becomes a real ceiling around month six of production use — and it’s not a workaround that exists, it’s a missing feature.
Pros:
- Free tier with 10,000 subscribers — a functional product, not a demo
- Automation sequences are fast to configure and easy to debug
- Tagging avoids the duplicate-contact billing common on list-based platforms
- Subscriber import with tag mapping works cleanly in under 10 minutes
- Creator Pro subscriber scoring helps identify engaged contacts worth prioritizing
Cons:
- No native Shopify, HubSpot, or Salesforce integration — Zapier dependency adds $20+/mo in middleware costs and creates silent failure risk
- No dynamic content blocks — can’t conditionally show email sections based on subscriber attributes without building separate sends
- Landing page template library is limited (~50 vs Mailchimp’s 100+)
- At 25,000 subscribers, Creator Pro runs over $200/mo — evaluate ActiveCampaign at that scale
Score: 8.6/10
Mailchimp
Best for: Shopify and WooCommerce stores, multi-brand businesses managing multiple audiences, and teams that need transactional and marketing email under one roof
Mailchimp is now an Intuit product, and that acquisition has been a mixed result. The core platform still works. Pricing has climbed steadily, and the dashboard now surfaces CRM-lite features, social scheduling, and website tools that most email marketers didn’t want and can’t easily hide. Try Mailchimp
Pricing breakdown:
- Free: $0, up to 500 contacts, 1,000 sends/month. One audience, basic templates, no automation.
- Essentials: $13/mo (500 contacts) to $80/mo (5,000 contacts). Three audiences, A/B testing, more templates.
- Standard: $20/mo (500 contacts) to $100/mo (5,000 contacts). Automations, segmentation, predictive send time, AI content tools.
- Premium: $350/mo base for up to 10,000 contacts. Multivariate testing, phone support, unlimited audiences, SSO.
In practice, the free plan is useful only for learning the interface. At 500 contacts, most businesses are already emailing a real audience and need automation — which is locked behind Standard ($20+/mo). Essentials exists mainly as a pricing step between free and the plan most teams actually need. This is the classic land-and-expand staircase: the advertised price gets you in the door, the feature you actually came for costs two tiers more.
E-commerce integration: This is where Mailchimp earns its place. The native Shopify sync pulls product catalog data directly into the email editor — product recommendation blocks, abandoned cart triggers, and purchase-based segments work without Zapier. During testing, I connected a Shopify sandbox in under 5 minutes and had an abandoned cart sequence live in another 20. The same setup via Kit would have required third-party middleware and at least an hour of configuration, plus an ongoing Zapier subscription.
AI tools: Mailchimp’s content writer (Standard plan) generates email copy from a prompt. The output quality is comparable to a capable junior copywriter working quickly — useful for first drafts, not final copy. Send-time optimization analyzes per-subscriber engagement patterns. Over a 4-week test on a 500-contact list, open rates lifted roughly 8% versus a fixed send time, though the sample size limits what I’d claim from that result. I can’t verify the vendor’s broader claims about send-time lift — take them as directional, not precise.
In practice, Mailchimp’s automation builder is split into two separate systems — “Classic Automations” and “Customer Journeys” — with different interfaces and different supported trigger types. Customer Journeys is the newer product, but Classic still handles some triggers the new builder doesn’t support. I spent 25 minutes figuring out which builder to use for a date-based birthday sequence. The answer was Classic. This fragmentation shouldn’t exist in a product at this price point, and it makes the new hire day-one test — can someone get productive without IT help? — noticeably harder to pass.
Pros:
- Native Shopify and WooCommerce sync — abandoned cart, product blocks, and purchase triggers work out of the box
- AI content writer and send-time optimization included on Standard
- Multiple audience management from one account (Essentials+)
- Spam filter testing before send on Standard+ — Kit doesn’t offer this
- Transactional email available as an add-on (Mailchimp Transactional, formerly Mandrill)
Cons:
- Free tier at 500 contacts is a funnel, not a product — insufficient for meaningful evaluation
- Two competing automation builders with different feature sets create a fragmented interface that confuses new users and slows onboarding
- SSO locked to Premium ($350/mo) — the standard security-feature tax that penalizes security-conscious SMBs below enterprise tier
- Post-Intuit dashboard bloat makes core email features harder to navigate; settings and campaigns compete for attention with tools you didn’t ask for
- At 5,000 contacts, Standard runs $100/mo — comparable to Kit’s Creator Pro, but Kit includes features Mailchimp reserves for higher tiers
Score: 7.1/10
The Verdict
For most small business owners, consultants, and creators: start with ConvertKit. The 10,000-subscriber free plan gives you real room to build before spending anything. Automations are faster to configure. The tagging system is more logical than list management. And if you outgrow it, the export is clean CSV and migration is well-documented — vendor lock-in risk is lower than most platforms in this category.
If you run an e-commerce store on Shopify or WooCommerce: Mailchimp wins on native integration alone. The time saved on abandoned cart setup versus building and maintaining a Zapier workflow pays for several months of subscription. Don’t rebuild your e-commerce email stack for marginal automation gains if Shopify is already wired to Mailchimp.
If you need phone support or multi-brand audience management at scale, Mailchimp’s Premium at $350/mo is the only option in this comparison — but at that budget, evaluate Klaviyo (e-commerce depth) and ActiveCampaign (automation complexity) before signing an annual contract.
If you’re a solopreneur just getting started: use Kit’s free plan for your first year. Avoid Mailchimp’s free plan entirely — 500 contacts is a marketing trap, not a growth tool.
FAQ
Can I migrate from Mailchimp to ConvertKit without losing my subscriber data?
Yes, but engagement history doesn’t transfer. Mailchimp exports your list as CSV with tags and custom fields — Kit imports it cleanly and maps custom fields on ingestion. What you lose: historical open and click rates, which resets engagement scoring from zero. Run a re-engagement campaign in the first 30 days to re-identify active subscribers before campaign metrics stabilize.
Is ConvertKit’s free plan actually usable, or is it a crippled demo?
It’s genuinely usable. You get broadcasts, one automation sequence, landing pages, and up to 10,000 subscribers. The main constraint is one active automation at a time — parallel onboarding and nurture sequences require Creator ($29/mo). For a business in its first year, one sequence covers most use cases. The free plan builds familiarity rather than creating dependency through locked features, which is a different approach than most competitors take.
Does Mailchimp’s automation require a paid plan?
Yes. Automation is locked behind Standard ($20/mo minimum). Essentials includes A/B testing and more templates but no automation. If automations are why you’re evaluating email platforms, budget for Standard from day one — Essentials will leave you one tier short of what you actually need, and the upgrade path is designed to feel obvious only after you’ve already paid.
Which platform handles GDPR compliance better?
Both include double opt-in, unsubscribe management, and data export tools. Mailchimp’s GDPR consent form builder is slightly more polished at the interface level and has more detailed documentation. Kit’s compliance tools are functional but less prominently surfaced — you need to know where to look in settings. Neither replaces legal review for businesses with substantial EU customer bases. Confirm that your vendor has signed a Data Processing Agreement before storing any EU subscriber data.
What happens when I outgrow ConvertKit at scale?
Creator Pro adds subscriber scoring, a referral system, and more detailed reporting. At 25,000 subscribers, Creator Pro runs over $200/mo — at that point, evaluate ActiveCampaign for deeper automation branching, or Klaviyo if you’ve shifted toward e-commerce. Kit’s data export is clean CSV and migration paths are well-documented, so the true cost of switching is lower than most platforms — mainly retraining time and rebuilding your automation sequences, not data loss.
