Klaviyo and Mailchimp are the two email marketing platforms most small businesses and online stores consider first. They look similar on the surface, with drag-and-drop emails, automations, signup forms and SMS, but they are built for different businesses. Klaviyo is built for e-commerce: it pulls in every order, product view and customer behavior from your store and turns it into segments, flows and revenue reporting. Mailchimp is an all-round marketing platform for small businesses of every kind, easy to start with and broad in features. This guide compares them head to head on e-commerce power, ease of use, real cost by list size, automation and which one fits which business.
Quick verdict. Choose Klaviyo if you run an online store, especially on Shopify, and want email and SMS driven by customer behavior and purchase data, with clear revenue attribution. Choose Mailchimp if you are a service business, nonprofit, creator or small store that wants an easy, versatile email tool at a slightly lower price.

The Head-to-Head Comparison
| Platform | E-commerce data and segmentation | Ease of use | True cost | Marketing breadth | PURIST Fit Score |
|---|---|---|---|---|---|
| Klaviyo | 10/10 | 8/10 | 6/10 | 8/10 | 8.1/10 |
| Mailchimp | 7/10 | 9/10 | 8/10 | 8/10 | 7.9/10 |
Klaviyo edges ahead on our framework because e-commerce data drives most email revenue for online stores. For businesses that do not sell online, Mailchimp is usually the better and cheaper fit, and the score would reverse.
Feature-by-Feature Breakdown
Store integration and customer data
Klaviyo's integration with Shopify and other e-commerce platforms syncs customers, orders, products, browsing and cart events in near real time. Every profile shows lifetime value, predicted next order date and churn risk, which you can use in segments and flows. Mailchimp integrates with Shopify, WooCommerce and other platforms and supports purchase-based segments and e-commerce automations, but with less depth and less predictive data.
Segmentation
Klaviyo segments can combine almost any condition: bought a specific product twice, viewed a category but did not buy, spent over a set amount in the last 90 days, predicted to churn. Mailchimp's segmentation is good for most small businesses, with tags, groups and behavior-based segments, and more advanced options on higher plans.
Automations and flows
Both offer automated flows for welcome series, abandoned carts, browse abandonment, post-purchase and win-back. Klaviyo's flows are built around e-commerce events and include strong branching and pre-built e-commerce templates. Mailchimp's Customer Journey builder is approachable and covers common scenarios, with more complex journeys on Standard and above.
Email editor and templates
Mailchimp's editor and template library are among the easiest to use, and its design tools suit businesses without designers. Klaviyo's editor is also drag and drop, with product blocks that pull items from your catalog dynamically and good template options for stores.
SMS and other channels
Klaviyo offers SMS and MMS, push notifications and a growing set of channels, managed alongside email with shared profiles and flows. Mailchimp offers SMS as an add-on in supported countries, plus landing pages, social posting and a website builder, making it broader for general small business marketing.
Reporting and attribution
Klaviyo's reporting is built around revenue: how much each campaign and flow generated, benchmarks against similar brands, and customer analytics. Mailchimp reports opens, clicks, conversions and e-commerce revenue, with advanced reporting on higher plans.
Deliverability
Both are established senders with good deliverability when you follow best practices: authenticated domains, consent-based lists and regular list cleaning. Results depend more on list quality and sending habits than on the platform.
The Real Cost Comparison Nobody Publishes
Approximate monthly cost for email only, at list prices, before promotions and SMS.
| List size | Klaviyo (Email) | Mailchimp (Essentials) | Mailchimp (Standard) |
|---|---|---|---|
| 10,000 contacts | about $150 | about $110 | about $135 |
At larger lists, both scale with contacts, and the gap depends on how each counts them. Klaviyo charges by active profiles that you can email, while Mailchimp has historically counted unsubscribed contacts toward your plan unless you archive them. A list with many unsubscribes or inactive contacts can cost more on Mailchimp than the headline price suggests, so clean your list before comparing.
For an online store, the more useful comparison is revenue. If Klaviyo's segmentation and flows generate even a small share more revenue per subscriber, the price difference is usually recovered quickly. For a business that does not sell online, that advantage largely disappears.
Hidden Costs and Traps
Contacts you cannot email still cost money. Archive or remove unsubscribed and long-inactive contacts regularly, on either platform.
SMS is extra. SMS is billed separately on both platforms, by message credits or add-ons, and costs vary by country.
Automatic plan upgrades. Both move you to a higher tier when your list grows past your plan. Monitor list growth and sign-up sources.
Feature gating. Some advanced features, such as multivariate testing, advanced segmentation and certain reports, sit on higher plans.
Migration effort. Moving lists is easy, but rebuilding flows, templates and segments takes time. Document your automations before you switch.
