Mailchimp vs Klaviyo
Mailchimp built its reputation as the beginner-friendly email marketing platform for everyone. Klaviyo built its reputation as the e-commerce email platform that actually drives revenue. Both send emails — but the philosophy, pricing model, and results diverge sharply as your list grows.

Best For
Choose Mailchimp if you...
- • Run a blog, agency, or service-based business
- • Just starting with email marketing
- • Need landing pages and basic automations
- • Have a small list and want a generous free tier
Choose Klaviyo if you...
- • Sell products online (Shopify, WooCommerce, etc.)
- • Want purchase-based segmentation and flows
- • Need SMS + email in one platform
- • Have data to leverage for revenue attribution
The Verdict
Klaviyo wins for e-commerce. Mailchimp wins for everyone else. If you run a Shopify, WooCommerce, or BigCommerce store, Klaviyo's deep integration with purchase data, abandoned cart flows, and revenue attribution makes it the obvious choice — most serious DTC brands see 20–30% of revenue attributable to Klaviyo alone.
Mailchimp is still the right tool for content creators, service businesses, nonprofits, and anyone who doesn't have product purchase data to leverage. Its free tier (up to 500 contacts) is generous, and the interface is the easiest to onboard in email marketing.
