Klaviyo and Mailchimp are two of the most popular email marketing platforms in 2026 but they serve different markets. Klaviyo is built specifically for e-commerce and is the dominant platform for Shopify stores. Mailchimp is a general-purpose email tool suitable for businesses of all types. This comparison breaks down pricing, features, and which platform is right for your business.
Pricing Comparison by List Size
| Contacts | Klaviyo Email | Mailchimp Essentials | Mailchimp Standard |
|---|---|---|---|
| Up to 500 | Free | $13/mo | $20/mo |
| 1,000 | $45/mo | $26.50/mo | $35/mo |
| 2,500 | $60/mo | $59/mo | $75/mo |
| 5,000 | $100/mo | $75/mo | $100/mo |
| 10,000 | $150/mo | $110/mo | $135/mo |

Klaviyo is more expensive than Mailchimp at most list sizes but its e-commerce features justify the premium for online stores. At 2,500 contacts, pricing is nearly identical. Above 5,000 contacts, Klaviyo becomes more expensive.

Frequently Asked Questions
Is Klaviyo better than Mailchimp?
For e-commerce, yes — Klaviyo’s Shopify integration, behavioural segmentation, and revenue attribution are significantly more advanced than Mailchimp’s. For non-e-commerce businesses, Mailchimp is easier to use and cheaper at smaller list sizes. The right choice depends on whether you run an online store.
Is Klaviyo more expensive than Mailchimp?
At 1,000 contacts, Klaviyo costs $45/month vs Mailchimp Essentials at $26.50/month. At 2,500 contacts the pricing converges. At very large lists, Klaviyo becomes significantly more expensive. However, Klaviyo’s e-commerce features typically generate higher revenue per contact, making the premium justifiable for online stores.
Does Klaviyo work with Shopify?
Yes. Klaviyo has a native Shopify integration that syncs customer data, purchase history, and browsing behaviour automatically. It is the most popular email marketing app in the Shopify App Store. The integration enables highly specific segmentation — for example, targeting customers who purchased a specific product more than 30 days ago but have not returned.
Can I switch from Mailchimp to Klaviyo?
Yes. Klaviyo has a dedicated Mailchimp migration tool that imports your contacts, lists, and segments automatically. The migration typically takes less than an hour. Historical campaign data does not transfer but contact data and segments migrate cleanly.
Is Mailchimp good for e-commerce?
Mailchimp has e-commerce features including abandoned cart emails, product recommendations, and purchase data segmentation — but these are less sophisticated than Klaviyo’s. For small e-commerce stores just getting started, Mailchimp is sufficient. For stores generating significant revenue from email, Klaviyo’s advanced segmentation and revenue attribution typically justify the higher cost.
How to Choose Between Klaviyo and Mailchimp
The decision between Klaviyo and Mailchimp comes down to one question: are you running an e-commerce store? If yes, Klaviyo’s native Shopify and WooCommerce integration, behavioural segmentation, and revenue attribution make it the stronger choice despite the higher cost. If no, Mailchimp’s easier interface and lower price point at small list sizes make it the better starting point.
Consider your list size carefully before deciding. At 500 contacts, Klaviyo is free and Mailchimp Essentials costs $13/month — Klaviyo wins on price. At 1,000 contacts, Klaviyo is $45/month and Mailchimp Essentials is $26.50/month — Mailchimp is cheaper. At 2,500 contacts the gap narrows significantly, and above 5,000 contacts both tools are similarly priced.
Klaviyo Key Features in Detail
Flows (Automation): Klaviyo’s automation builder uses triggers based on e-commerce events — abandoned cart, product viewed, purchase made, customer anniversary. These flows are more sophisticated than Mailchimp’s equivalent because they pull real-time data from your store.
Segmentation: Klaviyo lets you segment by purchase history (bought X but not Y), predicted lifetime value, browsing behaviour, and custom properties synced from your store. This level of segmentation is only possible because of the deep Shopify/WooCommerce integration.
Revenue Attribution: Every campaign and flow in Klaviyo shows attributed revenue — how much money was generated from that email within a set attribution window. This makes it straightforward to calculate ROI on email marketing spend.
SMS: Klaviyo handles SMS marketing in the same platform as email, with the same segmentation and automation capabilities. Mailchimp requires a separate product for SMS.
Mailchimp Key Features in Detail
Email Builder: Mailchimp’s drag-and-drop email builder is widely considered the most beginner-friendly of any major platform. Templates are polished and professional without requiring design skills.
Landing Pages: Mailchimp includes landing page creation in all plans — useful for running campaigns without a separate landing page tool. Klaviyo’s landing page capabilities are more limited.
Audience Management: Mailchimp’s audience management is straightforward for general email lists. It handles tags, groups, and segments effectively for non-e-commerce use cases like newsletters, event announcements, and B2B communications.
Integrations: Mailchimp integrates with 300+ tools including most major CRMs, e-commerce platforms, and marketing tools. The breadth of integrations is slightly wider than Klaviyo’s.
Klaviyo vs Mailchimp: Which Has Better Deliverability?
Both Klaviyo and Mailchimp maintain strong email deliverability rates. Klaviyo’s deliverability is specifically optimised for e-commerce sending patterns — high-volume transactional and promotional emails. Mailchimp’s deliverability infrastructure is robust for general email marketing. Independent deliverability tests consistently place both tools in the top tier. Neither has a significant advantage over the other on raw deliverability rates.
Migration: Switching Between Klaviyo and Mailchimp
Switching from Mailchimp to Klaviyo is straightforward — Klaviyo has a dedicated migration tool that imports contacts, lists, and segments automatically. The migration typically completes in under an hour. Historical campaign data does not transfer but contact data migrates cleanly.
Switching from Klaviyo to Mailchimp requires exporting contacts as a CSV and re-importing. Automation workflows need to be rebuilt from scratch in Mailchimp’s format. The migration is more manual in this direction.
