Klaviyo vs Mailchimp for Shopify: Which Makes More Money?

This is not a feature-table contest. It’s a question of how much of your revenue depends on segmentation, lifecycle flows and Shopify data — and how much you’re paying for both.

The real difference is the data model

Both platforms connect to Shopify. Both can send a welcome email and an abandoned-cart reminder. The difference shows up when you ask better questions: which customers bought twice, which products they viewed before purchasing, which segment is about to churn, and which flow produced the revenue.

Klaviyo is built around customer events and profiles. Mailchimp is built around audiences and campaigns, with Shopify data layered in. That difference matters more as your store grows — not less.

Where Klaviyo wins for Shopify

Event-based segmentation. Build segments from what customers viewed, bought, abandoned or did repeatedly — not just tags and list membership.
Flows are the default, not an upsell. Klaviyo’s free plan includes multi-step flows and A/B testing; Mailchimp’s free plan does not include automation flows. Paid Mailchimp plans unlock flows, but the depth varies by tier.
Revenue attribution. Klaviyo reports which flow and campaign produced revenue, which makes it easier to decide what to scale and what to delete.
Ecommerce integrations. Shopify, product catalog, reviews, SMS and 400+ integrations share one customer profile. That reduces the “which tool has the real data?” problem.
Active-profile pricing. Klaviyo prices on active profiles and states that it does not charge for inactive or opted-out profiles. Mailchimp prices on contacts and plan tier, with send limits and overages.

Where Mailchimp is enough

You’re just starting. Both platforms offer a free plan for up to 250 contacts/profiles. Mailchimp’s free plan includes 500 sends per month and basic campaigns; it’s a reasonable place to learn.
Email is mostly a newsletter. If you send one or two campaigns a month and don’t need deep automation, Mailchimp’s simpler interface may be easier for a small team.
You need broader brand tools. Mailchimp includes landing pages, forms and a wider content toolkit. If email is one part of a bigger content operation, that can matter.
Budget is the deciding factor. For a very small list, Mailchimp’s paid entry point can be lower. But compare the total cost at your actual contact count and required features — not the headline price.

Pricing: compare the structure, not the sticker

Current free-plan limits are similar on the surface: both cap you at around 250 contacts/profiles and 500 sends per month. The difference is what you get inside that limit. Klaviyo’s free plan includes multi-step flows and A/B testing. Mailchimp’s free plan does not include automation flows; its paid tiers add flows, more sends and more seats.

Paid pricing is where the comparison gets less obvious. Klaviyo prices primarily on active profiles plus email/SMS usage. Mailchimp prices on contacts and plan tier, with monthly send limits and overage charges. At the same contact count, one can be cheaper this month and more expensive after your list grows or you add SMS.

Instead of comparing “starting at” prices, calculate:

Your monthly subscription at the exact contact/profile count you have today.
Your expected email sends and SMS credits.
Overage charges if you exceed the plan.
The features you actually need: flows, segmentation, A/B testing, SMS, reporting, seats.
The revenue those features produce — or the time your team spends working around the missing ones.

Always check the official pricing pages before buying, because plan names, limits and promotional offers change: Klaviyo pricing and Mailchimp pricing.

Which one should you choose?

Answer these honestly:

Do you sell products people buy more than once?
Is email already responsible for a meaningful share of revenue?
Do you need segments based on behaviour, not just tags?
Will you actually build and maintain flows?
Do you need SMS in the same platform?
Does your team have the time to learn a deeper tool?
Is your list clean, or are you paying for years of unengaged contacts?
Are you willing to migrate templates and flows, not just contacts?

Most Shopify stores with repeat purchase answer “yes” to the first four. That points to Klaviyo. A store with a small list, a simple newsletter and no appetite for lifecycle work can stay on Mailchimp and revisit later.

If you migrate from Mailchimp to Klaviyo

Clean the list first. Don’t import years of unengaged contacts and pay for profiles that will never open. Suppress hard bounces and long-term inactive addresses.
Import the history you need. Contacts, engagement history and Shopify order data. Check that the Shopify integration is connected before you build segments.
Rebuild the core flows. Welcome, abandoned cart/checkout, browse abandonment, post-purchase and winback. Don’t try to recreate every Mailchimp automation on day one.
Keep Mailchimp sending while you build. Run both in parallel until the new templates and flows are tested. Then switch the store over.
Warm up and monitor. Watch deliverability, click rates and revenue per recipient for the first few weeks. A migration is not finished when the import completes.

The expensive mistake: switching platforms but keeping the same three generic emails. Klaviyo’s advantage is segmentation and flow depth. If you don’t use those, you’re paying more for the same result.

Frequently asked questions

Is Klaviyo better than Mailchimp for Shopify?

For most Shopify stores with repeat purchase and a real lifecycle program, yes. Klaviyo’s data model, flows and revenue attribution are built around ecommerce. Mailchimp can be enough for a simple newsletter or a very small store that only sends occasional campaigns.

Can I use Mailchimp’s free plan with Shopify?

Yes, but the free plan is limited to 250 contacts and 500 sends per month, and automation flows are not included. For a store relying on welcome, abandoned-cart and post-purchase flows, a paid Mailchimp plan is usually required.

Does Klaviyo charge for inactive contacts?

Klaviyo prices on active profiles and states that it does not charge for inactive or opted-out profiles. Check the current pricing page for the exact definition and plan limits before you commit.

How long does a migration take?

A small store can usually migrate in a few days; a store with complex segments, templates and flows should plan one to two weeks. Keep Mailchimp sending while you rebuild, clean the list before importing, and test every flow before switching.
