Klaviyo vs Mailchimp: Which Is Better for Ecommerce?
If you run a Shopify store and email drives real revenue, Klaviyo is the better pick; if you are a small business or content publisher who wants one cheap, simple tool for newsletters, Mailchimp wins. That is the short version of the Klaviyo vs Mailchimp question, and most of the disagreement online comes from people comparing the two for different jobs. Klaviyo was built around ecommerce data and deep segmentation. Mailchimp grew up as a general-purpose newsletter tool and now sells a wider marketing suite to small businesses. Both send good email. The right answer depends on whether your store’s catalog and purchase behavior need to drive your automations, or whether you mostly need to send a clean broadcast to a list. This guide compares pricing, ecommerce flows, deliverability, and fit, based on running both platforms for client brands.
How much do Klaviyo and Mailchimp cost?
Pricing on both platforms scales with contact count, but they count contacts differently, and that single difference decides a lot of cases.
Mailchimp’s free plan covers up to 500 contacts. Its paid Standard plan runs roughly $100 to $135 per month at 10,000 contacts as of 2026. The catch is that Mailchimp bills you for all contacts on your list, including people who unsubscribed or never engaged. A messy, inherited list inflates the bill.
Klaviyo’s free plan covers up to 250 contacts. Email at 10,000 active profiles costs around $175 per month at the time of writing. The key word is active: Klaviyo charges only for profiles you actually email, so suppressed and dormant contacts do not add to the cost. Below roughly 5,000 contacts Mailchimp is the cheaper of the two. Above that line the difference shrinks and the active-only model starts working in Klaviyo’s favor for stores with large, partly inactive lists.

Which is better for Shopify and ecommerce flows?
Both platforms support the flows that matter to a store: a welcome series, abandoned cart, post-purchase, win-back, and browse abandonment. If your bar is “does it send an abandoned-cart email,” either tool clears it.
Klaviyo pulls ahead on depth. Its Shopify integration is native, so it reads product data, order history, and on-site behavior without a middle layer. You can build a segment like “bought from the candle collection twice but not in 90 days and opened the last email” and trigger a flow off it. That kind of catalog-aware targeting is where ecommerce revenue actually comes from.
Mailchimp reaches Shopify through a third-party connector. The core flows work, but product-level data and granular purchase segments are harder to wire up and less reliable. For a store running simple automations on a modest catalog, that is acceptable. For a brand that wants email to behave like a salesperson who knows what each customer bought, the shallow integration becomes a ceiling. If you want flows built and managed for you, that is the core of our managed email service.
When we migrate brands between the two, the flows almost never transfer cleanly; the team rebuilds welcome, cart, and post-purchase sequences from scratch because Klaviyo and Mailchimp model customer data in incompatible ways.
Which has better deliverability?
Platform choice is a small part of whether your email reaches the inbox. List hygiene, domain authentication, and how often you mail unengaged people matter far more. Both Klaviyo and Mailchimp run reputable shared sending infrastructure, and both can hit strong inbox placement.
Where Klaviyo helps is suppression. Its segmentation makes it simple to stop emailing people who have not opened in 60 or 90 days, which protects your sender reputation. Mailchimp can do this too, but because it bills for every contact, some senders hold onto dead addresses to feel like they are getting value, which quietly hurts deliverability.
For context, 2025 ecommerce benchmarks put the average open rate near 32.7% and click-through around 2.1%. Hitting or beating those numbers is mostly about who you send to and whether your domain is authenticated, not which logo is on the dashboard. We cover the setup in detail in our guide on how to improve email deliverability.
Who should pick Klaviyo, and who should pick Mailchimp?
Pick the tool that matches the job, not the one with the louder fanbase. A content business and a Shopify store have different needs, and the Klaviyo vs Mailchimp choice should follow from that.
Choose Klaviyo if email is a real revenue channel for an ecommerce store, especially on Shopify, and you want flows driven by what customers actually buy and browse. Choose Mailchimp if you are a small business, creator, or content publisher who wants one affordable tool to send newsletters and run a few simple automations without heavy setup.
Verdict: Klaviyo vs Mailchimp
For an ecommerce brand that takes email seriously, Klaviyo is the stronger platform. Its biggest pro is native, catalog-aware Shopify segmentation that turns purchase behavior into revenue flows; its biggest con is that it costs around $175 per month at 10,000 active profiles and is the pricier option once you are past the smallest tiers.
For a small business or newsletter-led brand, Mailchimp is the better fit. Its biggest pro is the lower entry cost, with a 500-contact free tier and roughly $100 to $135 per month at 10,000 contacts; its biggest con is that it bills for every contact including unsubscribed ones, and its Shopify integration stays shallow.
