Which is better for Shopify and e-commerce?
Klaviyo
Wins sectionPower smarter digital relationships
Klaviyo is the stronger choice when Shopify data is the center of the retention program. Customer and commerce events feed profiles, segmentation, campaigns, reporting, and Flows, which makes abandoned-cart, post-purchase, win-back, and repeat-purchase work easier to manage from the same data model.
Mailchimp
The #1 AI-powered email marketing and automations platform
Mailchimp's current Shopify integration is more capable than a basic connector. It syncs customer and order information and can sync Shopify segments for personalized email and SMS marketing. Mailchimp remains credible for smaller stores, especially when campaigns and ease of use matter more than operating a specialized ecommerce retention platform.
Winner: Klaviyo. Klaviyo is the stronger choice when Shopify data is the center of the retention program.
Which has better segmentation?
Klaviyo
Wins sectionPower smarter digital relationships
Segmentation is one of Klaviyo's core strengths. The platform combines engagement, profile, event, and commerce data so segments can reflect customer behavior rather than only list membership. Its free plan includes basic segmentation; more advanced data and analytics products expand the model further.
Mailchimp
The #1 AI-powered email marketing and automations platform
Mailchimp supports segmentation across its marketing plans, but criteria and advanced capabilities vary by tier. It is easier when the audience model is based on campaign engagement, tags, contact fields, and synced commerce segments. Klaviyo is stronger when continuous customer events and order behavior define the audience.
Winner: Klaviyo. Segmentation is one of Klaviyo's core strengths.
Which has better automation?
Klaviyo
Wins sectionPower smarter digital relationships
Klaviyo Flows are designed around customer and commerce events, which makes ecommerce lifecycle automation the natural use case. Users can build automations and segmentation on the free plan, then scale profile, send, channel, and support limits as the program grows.
Mailchimp
The #1 AI-powered email marketing and automations platform
Mailchimp offers marketing automation flows across paid tiers. Essentials allows up to four flow steps, while higher plans expand the number and sophistication of flows. It is sufficient for welcome, follow-up, and straightforward commerce sequences, but Klaviyo is more naturally aligned with event-heavy store lifecycle work.
Winner: Klaviyo. Klaviyo Flows are designed around customer and commerce events, which makes ecommerce lifecycle automation the natural use case.
Which is easier to use?
Klaviyo
Power smarter digital relationships
Klaviyo asks the team to understand profiles, events, segments, consent, channels, and Flows. That setup is worthwhile for a mature ecommerce program, but it creates more governance and onboarding work than a campaign-first platform.
Mailchimp
Wins sectionThe #1 AI-powered email marketing and automations platform
Mailchimp is easier when the immediate job is building an audience, publishing forms or landing pages, and sending campaigns. The free plan includes one audience, one seat, a welcome automation, and basic reporting, giving a small team a narrower first-use path.
Winner: Mailchimp. Mailchimp is easier when the immediate job is building an audience, publishing forms or landing pages, and sending campaigns.
Which has better SMS marketing?
Klaviyo
Wins sectionPower smarter digital relationships
Klaviyo includes 150 monthly mobile-message credits on the free plan and lets email and mobile messaging share customer profiles, segmentation, reporting, and Flows. It is the cleaner option when coordinated ecommerce email and SMS are part of the same retention program.
Mailchimp
The #1 AI-powered email marketing and automations platform
Mailchimp offers SMS and MMS as an add-on for paid marketing plans in selected markets. Accounts must apply and be approved before purchasing credits. It can work for an existing Mailchimp audience, but availability, approval, and credit cost must be checked for the account's market.
Winner: Klaviyo. Klaviyo includes 150 monthly mobile-message credits on the free plan and lets email and mobile messaging share customer profiles, segmentation, reporting, and Flows.
Which is cheaper?

Frequently Asked Questions
It can be for ecommerce businesses that will use customer and order data for segmentation, lifecycle Flows, attribution, and coordinated mobile messaging. Mailchimp usually offers better value when the program is mainly newsletters, straightforward campaigns, forms, and short automations.
For ecommerce, yes. Klaviyo is usually better than Mailchimp because it has deeper store data, stronger segmentation, better abandoned-cart and post-purchase automation, and built-in SMS. For non-ecommerce businesses, Mailchimp is often the better fit because it is simpler, cheaper to start with, and more general-purpose.
Yes. Klaviyo integrates with WooCommerce, BigCommerce, Magento, and custom platforms via API. But its strongest integrations are with Shopify. If you're not running an e-commerce store at all, Mailchimp is a better fit.
Klaviyo is usually better for ecommerce SMS because mobile messaging shares customer profiles, segments, reporting, and Flows with email. Mailchimp offers SMS as an add-on for approved paid accounts in selected markets, which can be enough for teams that already manage their audience there.
Yes. Mailchimp's Shopify integration syncs customer and order information and can sync Shopify segments for personalized email and SMS marketing. Klaviyo remains the more ecommerce-specialized choice, but Mailchimp is not limited to a basic contact-only connection.
Both have free limits of 250 contacts or active profiles and 500 monthly email sends. Mailchimp Essentials starts at $13 per month for 500 contacts. Klaviyo paid pricing scales with active profiles, sends, channels, and added products. Mailchimp counts subscribed, unsubscribed, and non-subscribed contacts unless they are archived, cleaned, or deleted.
Neither platform guarantees better inbox placement. Domain authentication, consent, complaint rates, list hygiene, content, volume changes, and sending cadence matter more than the vendor name. Evaluate each platform's authentication and monitoring workflow against the way your team actually sends.
Yes. Export and clean contacts, preserve consent and suppression status, map fields and segments, reconnect ecommerce data, and rebuild automations as Klaviyo Flows. Test forms, authentication, tracking, unsubscribe behavior, and high-value lifecycle messages before moving production sends.

Klaviyo Review
Klaviyo is one of the best choices for serious e-commerce brands that rely on email and SMS to drive revenue. It is a weaker fit for simpler stores, non-e-commerce teams, or businesses that mainly need a lighter and cheaper email platform.
Mailchimp Review
Mailchimp is still a strong choice for small businesses that want an easy email platform with a free plan and a polished editor. It becomes a weaker choice for teams that need deeper automation, better value at scale, or tighter e-commerce segmentation.
Compare the Pricing in More Detail
If cost is the real sticking point, these pricing guides break down the entry tiers, upgrade pressure, and the budget traps that are harder to show in a simple comparison table.
Klaviyo Pricing
Klaviyo pricing makes sense for ecommerce stores that can turn segmentation, flows, email, and SMS into repeat revenue. It gets expensive when active profiles grow faster than the store's lifecycle marketing program, or when SMS credits are bought without a clear campaign plan.
Mailchimp Pricing
Mailchimp pricing is fine when your list is small and your email program is simple. It becomes much less compelling once contact growth, inactive records, and higher-tier feature gates start shaping the real monthly cost.
