Klaviyo and Mailchimp overlap enough to cause real confusion, but they are aimed at different jobs. Klaviyo is built for e-commerce stores that want to act on customer behavior data. Mailchimp is the general-purpose default for newsletters and small business marketing. If you run a Shopify or WooCommerce store, the choice matters a lot. Choosing wrong costs you either money or revenue you could have recovered.
The verdict
Klaviyo wins for e-commerce. Mailchimp wins for simplicity and general use. If you run an online store and want to send emails triggered by what people browse, abandon, or buy, Klaviyo pays for itself quickly through recovered carts and post-purchase flows. If you run a newsletter, a service business, or a small shop where basic campaigns are enough, Mailchimp is cheaper and easier to use.

Pricing
Both charge by contact count. Klaviyo's free plan covers 250 contacts and 500 emails per month. Mailchimp's free plan covers 500 contacts and 1,000 sends. Mailchimp is the more generous starting point on the free tier.
On paid plans, Klaviyo runs more expensive. At 500 contacts, Klaviyo is $20 per month versus Mailchimp's $13. At 5,000 contacts, Klaviyo is around $100 per month and Mailchimp's Essentials plan is around $75. At 50,000 contacts, the gap is larger. For a pure newsletter with no product catalog, you are paying for power you will not use.
For e-commerce stores, the math shifts. A single well-tuned abandoned cart flow can recover enough revenue in the first month to more than cover Klaviyo's higher cost. The premium is easier to justify when the platform is actively generating revenue, not just sending newsletters.
E-commerce automation
This is where Klaviyo separates itself from every other email platform, not just Mailchimp. Klaviyo connects natively to Shopify, WooCommerce, BigCommerce, and other platforms, pulling live product data, order history, and browse behavior into the platform.
You can build flows that fire when someone views a product category three times but does not buy, when a customer has not ordered in 90 days, when an order is delivered and it is time for a review request, or when someone adds items to their cart and leaves. These flows trigger off real store events in real time.
Mailchimp can connect to Shopify and has automation, but the behavioral data it receives is shallower. You can trigger off abandoned cart events, but the granularity of browse data, predictive analytics, and segment-level product recommendations that Klaviyo offers is simply not available.
Segmentation
Klaviyo's segmentation is built around purchase and behavior data. You can build a segment of "customers who spent over $200 in the last 6 months and have not bought in 45 days" or "people who clicked a product email but never purchased" with just a few clicks. Predictive segments can estimate a customer's next order date or lifetime value.
Mailchimp's segmentation is contact-property based and covers the common cases well. For stores, it is less flexible and does not tap the same depth of purchase behavior data.
Ease of use
Mailchimp is the friendlier starting point. The editor is clean, campaigns are straightforward, and you can be live in an hour with no prior setup. Klaviyo has a steeper ramp because the platform assumes you are connecting a store, building flows from templates, and thinking in terms of customer lifecycle stages.
Once you are set up in Klaviyo, the flow builder is genuinely powerful and not hard to use. But that first week of setup takes real effort, especially if you are a solo founder connecting a store for the first time.
Templates & design
Both platforms have solid email editors. Klaviyo's templates are designed with product blocks, dynamic content, and e-commerce layouts in mind. Mailchimp's library is larger with more general-purpose designs. If you sell products and want templates that look like product emails, Klaviyo's starting points are more on-target.
Deliverability
Both platforms have solid deliverability track records. Neither is a meaningful differentiator here. Your list quality and sending consistency matter more than which platform you use. Both support DKIM, SPF, and DMARC authentication.
Free plan
Mailchimp's free plan is the better starting point for volume: 500 contacts and 1,000 sends per month. Klaviyo's free plan allows 250 contacts and 500 sends. For a new store testing the waters, Mailchimp's free tier goes a bit further before you have to pay. Once you need the flows and integrations Klaviyo offers, the upgrade is worth it.
Support
Klaviyo offers email and chat support on paid plans, with documentation that is thorough around flows, integrations, and e-commerce use cases. Mailchimp's free-tier support is limited to email only for the first 30 days, then email and chat on paid tiers. Neither offers phone support as a standard option.
Who should pick which
- Pick Klaviyoif you run an e-commerce store on Shopify, WooCommerce, or BigCommerce and want automation that acts on real purchase and browse behavior. This is the platform's primary job and it does it better than any alternative.
- Pick Mailchimp if you run a newsletter, a service business, or a small retail shop where simplicity and cost matter more than deep behavioral targeting. If you are not pulling product data into your flows, Mailchimp is cheaper and easier.
FAQ
Is Klaviyo cheaper than Mailchimp?
No. Klaviyo is more expensive at every comparable list size. At 500 contacts, Klaviyo starts at $20 per month versus Mailchimp's $13. The premium is worth it for e-commerce stores where automated flows generate measurable revenue. For newsletters or service businesses, it is usually not.
Which is better for Shopify, Klaviyo or Mailchimp?
Klaviyo, clearly. Klaviyo's Shopify integration is deep and native. It pulls in browse events, purchase data, and product catalog information in real time. Mailchimp had its official Shopify app removed from the Shopify App Store in 2019 (third-party integrations exist, but it adds friction). For Shopify stores, Klaviyo is the standard.
Can I migrate from Mailchimp to Klaviyo?
Yes. Klaviyo has a dedicated Mailchimp import tool. It will bring over your subscriber lists, tags, and suppression lists. The migration itself is straightforward; most of the work is rebuilding your flows inside Klaviyo's interface, which Klaviyo's pre-built flow templates help speed up.
Does Klaviyo have a free plan?
Yes. Klaviyo's free plan covers up to 250 contacts and 500 email sends per month. It includes access to flows and segmentation, so you can test the core features before committing. Mailchimp's free plan is slightly more generous at 500 contacts and 1,000 sends.
Which has better deliverability, Klaviyo or Mailchimp?
Both have strong deliverability records. Deliverability is not a meaningful differentiator between the two platforms. List hygiene, sending frequency, and engagement rates matter far more than the platform itself.
A third option if you sell B2B: Bobb
Both tools above are built to send email. If the job of your newsletter is to sell (book meetings, surface buyers, move pipeline), that is a different job, and it is the one Bobb was built for. Bobb finds the people in your list most likely to buy, writes and sends for you, and books the meeting when someone raises a hand. You send from a pre-warmed platform domain, so you land in the inbox from day one with no domain to warm.
If your newsletter is purely content or consumer e-commerce, pick the winner above. If it is supposed to generate pipeline, start free and see the difference on your own list.
