Klaviyo vs Mailchimp: E-commerce Email Comparison 2026

Our pick for online stores: Klaviyo, with a budget caveat

For an online store that sells products, especially on Shopify, Klaviyo is the better pick. Its profiles hold order, browse and cart events, and its ready-made flows for abandoned carts and post-purchase follow-ups are built around those events. The monthly Email plan starts at $20 a month for 500 profiles. Mailchimp is the better pick for a small store with a modest list that mostly sends newsletters and occasional promotions: its Essentials plan is $13 a month for 500 contacts, billed monthly. The rest of this page explains where that trade-off changes as your list grows.

Prices on this page were read from each vendor's pricing page on 7 October 2026. Klaviyo prices are monthly and are charged per active profile. Mailchimp prices are monthly and are tied to contact tiers, and each tier also sets a monthly send allowance. Annual-billing figures are not shown here, and where a price is not published we say so instead of estimating it.

Who this comparison is for

This comparison is for store owners and marketing leads who must choose one email platform for a product catalogue, and who expect to send more than a weekly newsletter. If you run a blog, a service business or a membership community with no order data, most of the e-commerce-specific material below will not matter to you, and you should read our general guide to marketing email tools before deciding.

The two platforms overlap more than their marketing suggests. Both let you import a list, build a signup form, design an email, schedule a campaign and report on opens and clicks. The real difference is what the platform knows about each customer, and how much of your store's behaviour it can use without manual setup. That difference is also what drives cost, because Klaviyo charges by the profiles you keep active while Mailchimp charges by contact tier and send volume.

Comparison at a glance

The table below compares the two tools on the points that matter most for an online store. Prices are the monthly starting points described above.

Free plans and their limits

Both vendors offer a free plan, which is useful for testing your sign-up form and template before you commit money.

Klaviyo's free plan covers 250 active profiles and 500 email sends a month, and includes $5 of mobile messages. That is enough to confirm that your Shopify connection imports orders correctly, but it is too small to judge the automation that matters most, because abandoned-cart and post-purchase flows only earn their keep once real traffic arrives.

Mailchimp's free plan covers one audience of up to 250 contacts, with up to 500 sends a month and a daily cap of 250 sends. It is generous for a newsletter that goes to a few hundred readers, but the daily cap means a 250-contact list cannot be sent to in a single burst of more than 250 emails in a day, which matters for launch days.

The practical test is simple. Put a real product, a real discount code and a real welcome flow on the free plan, then check whether the order data, the cart data and the sending limits behave as you expect. Only move to a paid plan once that test passes.

Klaviyo: what it does well for online stores

Klaviyo's main strength is that it treats orders and browsing as first-class data. For a store, that means a customer's profile can carry what they bought, what they viewed, what they abandoned in the basket and how often they return. Segments built on those signals can be updated automatically, so a campaign to lapsed buyers in one product category does not need a spreadsheet export each week.

The second strength is its flow library for e-commerce. Abandoned-cart, browse-abandonment and post-purchase sequences are available as starting points, and you adjust the timing, the copy and the discount rules rather than building each branch from nothing. For a store with a small team, that saves real hours in the first month.

Klaviyo also suits stores that want SMS alongside email. Email+SMS bundles are sold for each profile tier, and their price is on request, so you will need to request a quote before you plan a budget around texting.

Where Klaviyo falls short

The cost is the most common complaint, and it is structural. The Email plan is priced by active profiles, so a store that grows its list from 5,000 to 25,000 profiles moves from $100 a month to $400 a month on the monthly Email plan. Stores with large catalogues and long browsing histories will feel that jump. You also need to keep the list clean, because inactive or duplicate profiles still count toward the tier you pay for.

The second limitation is learning time. The segmentation and flow editors are powerful, and a poorly planned set of flows can send the same customer three overlapping offers in one afternoon. Someone on your team needs to own the flow map, not just the templates.

The third limitation is scope. Klaviyo is built for stores, so if you also run a newsletter, a membership programme or event invitations with no product data, you may find it more complicated than your use case requires.

Price: the Email plan starts at $20 a month for 500 profiles, with 1,000 profiles at $30, 2,500 at $60, 5,000 at $100, 10,000 at $150 and 25,000 at $400, all billed monthly. Full details are on Klaviyo's pricing page.

Mailchimp: what it does well

Mailchimp's strength is simplicity. The account setup, audience import, template editing and campaign scheduling are approachable for someone who has never run an email programme. For a store that sends a weekly newsletter with a product feature and a sale notice, that simplicity is worth a lot, because the team can keep the programme running when the one person who knows it is on holiday.

Mailchimp is also priced in a way that is easy to forecast for small lists. The Essentials plan is $13 a month for 500 contacts, billed monthly, and the Standard plan starts at $20 a month for the same 500-contact selector. Above that, pricing moves by contact tier: $100 a month for 2,501 to 5,000 contacts, $135 a month for 5,001 to 10,000, and $230 a month for 10,001 to 15,000. Each tier also carries a send allowance, which is the part of the plan you should check against your sending habits.

For stores that sell several product types or run service offers alongside products, Mailchimp's general-purpose tools can be an advantage. Its audience and campaign model does not assume that every subscriber is a buyer.

Where Mailchimp falls short

The e-commerce depth is the main gap. Product recommendations, browse-based triggers and lifetime-value segments need more manual configuration than they do in Klaviyo. A store that wants those features will spend time building them, and that time is a cost even if the subscription is cheaper.

The send allowance is the second gap. At the 2,501 to 5,000 tier the plan includes up to 60,000 emails a month. A 5,000-contact list sent twelve times a month uses the whole allowance, so a store that emails every day to a list of that size will hit the ceiling and need a higher tier. Count your planned sends per month before you pick a tier, not just your contact count.

The third gap is predictive analytics. Mailchimp's reporting covers the usual campaign metrics well, but it does not offer the depth of customer prediction that Klaviyo provides for stores.

Price: the Essentials plan is $13 a month for 500 contacts, billed monthly, and the Standard plan starts at $20 a month for 500 contacts. Tier prices are $100 a month for 2,501 to 5,000 contacts, $135 for 5,001 to 10,000 and $230 for 10,001 to 15,000. Pricing for the 1,500, 2,500 and 5,000-contact Essentials and Standard rows is not published in the way the tiers above are, so check Mailchimp's pricing page for those exact selectors.

What each tool costs at real list sizes

The table below uses three realistic list sizes and one larger one. Each cell names the plan and the monthly price for that list size. Where the vendor does not publish a price for that size, the cell says "pricing on request" rather than an estimate.

Two points from the table matter more than the single numbers. First, the gap between the tools is widest at small list sizes, where Mailchimp is about $7 a month cheaper at 500 contacts on the Essentials plan. Second, the gap narrows as the list grows: at 10,000 contacts Mailchimp's tier is $15 a month less than Klaviyo's Email plan, which works out to $180 a year.

Annual totals are simple to calculate from the monthly prices. At 5,000 profiles, Klaviyo's Email plan costs $100 × 12 = $1,200 a year. Mailchimp's 2,501 to 5,000 tier costs the same $100 × 12 = $1,200 a year. At 10,000, Klaviyo costs $150 × 12 = $1,800 a year and Mailchimp's tier costs $135 × 12 = $1,620 a year. Those are the figures to put in a budget, provided your send volume fits inside the Mailchimp allowance for that tier.

Remember that the subscription is only part of the bill. Klaviyo's e-commerce flows can justify a higher price if they recover revenue from abandoned carts and repeat purchases that you would otherwise lose, but that benefit must be measured in your own store's numbers, not assumed. Mailchimp's lower price is worth more if your team would otherwise pay someone to build the flows Klaviyo ships with.

Segmentation and automation for a store

Segmentation is where the two tools differ most in practice. In Klaviyo, a segment can combine purchase history, browsing behaviour and engagement in one rule set. A common store segment is "viewed a product in the last 30 days, has not bought in that category, and opened the last two emails." That segment updates by itself as customers act, and a flow can be triggered when someone enters it.

Mailchimp segments by contact fields, tags, purchase data where the integration supplies it, and engagement. The result is useful, but e-commerce triggers such as browse abandonment usually need more setup, and the segment logic is less granular. A small store can run a good programme on Mailchimp by keeping its segments short and its flows few, which is often the right approach for a team with limited time.

For automation, plan your flows before you open either tool. A workable first set for a product store is: a welcome series for new subscribers, an abandoned-cart reminder, a post-purchase thank-you with care instructions, a replenishment reminder for consumables, and a win-back email for customers who have not bought in six months. Start with those five. Add a browse-abandonment flow only once the cart flow is working, and always check that a customer who buys in the middle of a flow stops receiving the offer they no longer need.

Migration checklist

If you are moving from one platform to the other, the work is mostly in the data and the templates, not the sending. The table below lists the steps in the order we would follow them.

Keep an export of your full subscriber history and your campaign reports before you cancel anything. Some platforms limit access to historical data after a subscription ends, and you will want those reports when you compare results after the switch.

Decision table: which tool fits your situation

Use this table as a shortcut. Read across the row that describes your store and follow the pick and the reason.

How to choose

Start with three questions. How many people will look after the programme? How many contacts will you have in twelve months, not just today? How many emails will you send in a typical month? Those three answers narrow the choice faster than any feature list.

If your store is on Shopify, has at least a few thousand customers and has someone who can maintain flows, Klaviyo is the stronger choice even though the cost is higher. The order data is more usable, the flows save time, and the price difference at 10,000 contacts is $15 a month on the plans compared here.

If your store is small, sends mostly newsletters and has a team that cannot afford to learn a complex editor, Mailchimp is the sensible starting point. Its entry price is lower, its editor is easier, and you can add structure later. Set a review date at 5,000 contacts or when your monthly send count approaches 60,000, whichever comes first.

Whichever you pick, put a measurement in place before you move. Record your current open rate, click rate, revenue per email and abandoned-cart recovery, so that you can tell after a quarter whether the change paid for itself.

The bottom line

Klaviyo is the better pick for an online store that depends on product data and automated flows, and its Email plan starts at $20 a month for 500 profiles. Mailchimp is the better pick for a smaller store that values simplicity and a lower entry price, with its Essentials plan at $13 a month for 500 contacts. The gap is widest at small list sizes and narrows as the list grows, so the right answer depends on the list you will have, the sends you will make and the people who will run the programme.

Frequently asked questions

Is Klaviyo worth the higher price for a small Shopify store?

It can be, but only if the store has enough order volume for the flows to matter. At 500 profiles the Email plan costs $20 a month, and a store with a few abandoned carts a week may find that the flows pay for themselves. A store with very few orders will get more value from Mailchimp's lower price until its sales grow.

Does Mailchimp have a free plan I can use for a store?

Yes. The free plan covers one audience of up to 250 contacts, with up to 500 sends a month and a daily cap of 250. It is good for testing a welcome email and a sign-up form, but it does not include the e-commerce flows you would want for a live store.

Does Klaviyo's free plan include SMS?

The free plan includes $5 of mobile messages along with its 250 profiles and 500 email sends a month. Ongoing SMS use is priced separately, and Email+SMS bundle pricing is on request.

How do I compare the two platforms fairly?

Run the same welcome series and the same abandoned-cart reminder on both, to the same test list, for the same two weeks. Compare open rate, click rate, revenue per email and unsubscribe rate. Use the migration checklist above to keep the data identical between the two tests.

Can I move my automations from Mailchimp to Klaviyo?

Not as a direct copy. Automations are platform-specific, so you rebuild them. Start with the five-flow starter set in this guide, check each one with a test contact, and keep the old flows running until the new ones have sent a few real messages.

Which platform is better for sending a newsletter with a product section?

For a newsletter with a product section and no need for automated per-customer flows, Mailchimp is usually the simpler and cheaper choice. Move to Klaviyo when the newsletter has to respond to individual behaviour, such as sending a re-stock notice only to people who viewed the product.

Where can I check current prices before I buy?

Use each vendor's own pricing page: Klaviyo pricing and Mailchimp pricing. Prices change, and the figures on this page were read on 7 October 2026. Confirm the plan name, the contact or profile tier and the billing period before you commit.
