Klaviyo vs Mailchimp: Which One Actually Fits Your Store?
Klaviyo builds around deep ecommerce and Shopify data with behavior-driven flows, while Mailchimp is a broader, more general-purpose marketing suite for small businesses that email occasionally.
If you run an ecommerce store, especially on Shopify, and want behavior-based flows built on real purchase and browsing data, Klaviyo is generally the stronger fit despite costing more at most list sizes. If you are a small business sending general newsletters and occasional campaigns without deep ecommerce needs, Mailchimp's broader, more general-purpose suite is usually the simpler and cheaper starting point.
Klaviyo and Mailchimp both market themselves as email platforms for growing businesses, but they were built around different core assumptions. Klaviyo grew up as an ecommerce-first tool, syncing directly with Shopify (and other store platforms) to pull order history, browsing behavior, and product catalog data into segments and automated flows in close to real time. Mailchimp started as a general-purpose email marketing tool for small businesses of every kind and has added ecommerce features over time, but its store integrations typically rely more on third-party connectors and offer less native depth than Klaviyo's.
Both price by contact (or "profile") count with tiered plans that climb as your list grows, and both have shrunk their free tiers in recent years. The right pick usually comes down to how much of your revenue depends on behavior-triggered flows tied to a store versus how much you just need reliable, general email sends to a list.
Feature-by-Feature Comparison
| Feature | Klaviyo | Mailchimp |
|---|---|---|
| Pricing basis | Active profiles (contacts you can still reach) | Contacts stored, including unsubscribed contacts on some counts |
| Shopify / ecommerce integration | Native, real-time sync of orders, browsing behavior, and product catalog | Integrates with Shopify and other stores, but more often via third-party apps with less native depth |
| Behavioral segmentation | Deep, available on entry paid plans - built-in predictive metrics like CLV and churn risk on top tiers | Available, but more advanced segmentation is gated behind the Premium tier |
| Marketing automation flows | Multi-step, trigger-based flows are core to the product from the start | Multi-step automations available on Standard tier and above, not on Essentials or Free |
| SMS integration | Native Email + SMS plans with bundled credits, or SMS add-on to Email plans | SMS available as an add-on to paid plans, billed separately via purchased credit packs |
| Free tier | Free up to 250 active profiles | Free up to 250 contacts and 500 emails/month (cut back from higher limits in January 2026), no automation on Free |
| Analytics / reporting depth | Strong ecommerce-specific reporting: revenue per flow, predictive analytics, customer lifetime value | Solid general campaign and audience reporting, with ecommerce-specific reporting less deep than Klaviyo |
| Ease of use for non-ecommerce sends | More setup overhead if you are not connecting a store | Generally simpler and faster to get a basic newsletter or campaign out |
| Best ecosystem fit | Ecommerce brands, especially on Shopify, that want revenue-driven behavioral flows | General small businesses wanting one broad, easy-to-use marketing suite |
Pricing Compared
| Tier | Klaviyo | Mailchimp |
|---|---|---|
| Free | Free up to 250 active profiles | Free up to 250 contacts and 500 emails/month, no automation |
| Entry paid | Email plan from roughly $20/month at 251-500 profiles | Essentials from roughly $45/month at around 2,500 contacts |
| Mid tier (~2,500-5,000 contacts) | Roughly $30-45/month in this range, scaling with profile count | Standard from roughly $60/month at around 2,500 contacts - adds multi-step automation |
| Higher tier | Around $150/month at 10,000 profiles, climbing to roughly $720/month at 50,000 and about $2,300/month at 250,000 | Premium holds flat at roughly $350/month up to 10,000 contacts, then roughly $620/month at 25,000 |
Figures are approximate and current as of mid-2026, gathered from published vendor pricing pages and third-party pricing trackers. Both platforms price by contact/profile count and adjust tiers and inclusions periodically, so treat these as a starting point for your own current-rate check with each vendor, not a locked-in budget number.
Pricing is based on contact or profile count and changes periodically on both platforms - verify current tiers and inclusions directly with Klaviyo and Mailchimp before budgeting.
Pros & Cons
Klaviyo

- ✕ Ecommerce and Shopify integrations generally rely more on third-party apps and offer less native depth than Klaviyo
Which One Should You Actually Pick
You run a Shopify or ecommerce store
Klaviyo is usually the stronger fit - native order, browsing, and catalog sync feeds behavioral flows and predictive metrics that Mailchimp cannot match natively.
You are a general small business sending occasional newsletters
Mailchimp's broader, simpler suite is usually the easier and cheaper starting point if your sends are not built around store or purchase behavior.
You need SMS alongside email in one platform
Both offer SMS, but check current credit pricing and country coverage directly with each vendor - Klaviyo bundles it into Email + SMS plans, Mailchimp sells it as a separate add-on to paid tiers.
You are starting from zero and want to test before committing
Compare current free-tier limits directly on each vendor site before committing - both have shrunk free tiers in recent years, and the numbers change.
Why the Pricing Comparison Is Not Apples to Apples
Both platforms price primarily by contact count, but the details differ enough to trip up a quick comparison. Klaviyo counts "active profiles" - people you can still reach - while Mailchimp's contact counts have historically included unsubscribed contacts on some plans, which can inflate your effective cost beyond the headline number. Both vendors have also trimmed their free tiers over the past few years: Mailchimp cut its free plan down to 250 contacts and 500 emails per month with no automation in January 2026, and Klaviyo's free tier tops out at 250 active profiles. Neither free tier is meant for anything beyond a very small test list.
Because both platforms adjust plan names, inclusions, and prices periodically, the numbers in the tables above should be treated as a mid-2026 approximation, not a locked-in quote. Pull your actual contact count and run it against each vendor's current pricing calculator before deciding - a plan that looks cheaper at a glance can end up costing more once add-ons like SMS credits or higher automation tiers are factored in.
What the Platform Choice Does Not Solve
Picking the platform that fits your business model on paper does not by itself produce a working automation flow, a clean segmented list, or strong deliverability. Both Klaviyo and Mailchimp give you the mechanism - the flow builder, the segmentation rules, the send infrastructure - but the strategy underneath still has to be built. A store with messy order data will get weaker results from Klaviyo's behavioral flows than a store with clean product and customer data, and a Mailchimp list full of stale, unengaged contacts will hurt deliverability regardless of which automation tier you are paying for. Domain authentication (SPF, DKIM, DMARC) also still has to be configured correctly on either platform before volume sending begins - the platform does not do that step for you.
Common questions
It depends on your contact count and whether you need ecommerce-specific automation. At comparable list sizes, Mailchimp often looks cheaper on paper, but Klaviyo's ecommerce brands frequently report the flows pay for the price difference through higher revenue per email. Compare your actual contact count against both vendors' current pricing pages rather than relying on headline numbers.
No. Klaviyo integrates with several major ecommerce platforms, but its integration with Shopify specifically is the deepest and most commonly cited, which is why it is especially popular among Shopify merchants.
Contact list exports and imports are straightforward on both platforms. Automation flows and segmentation logic generally need to be rebuilt manually in the new platform, so budget time for that step, not just the data migration itself.
Only if your audience responds well to text messages and you can manage consent and compliance properly. Both platforms support SMS, but it is billed and configured separately from email in both cases, so verify current SMS pricing and country coverage with each vendor before assuming it is bundled in.
