Mailchimp vs Klaviyo

Mailchimp is a general-purpose email tool. Klaviyo is an ecommerce revenue engine. The architectural difference matters: Klaviyo ingests your entire Shopify catalogue, every customer's purchase history, browsing behaviour, and cart activity, then layers predictive analytics on top — estimated next order date, predicted lifetime value, churn risk score. Mailchimp can connect to Shopify and pull purchase data, but its core data model revolves around contacts and campaigns, not purchases and revenue. Klaviyo's customers attribute 30-40% of email revenue to automated flows. Pricing is tied up to 5K contacts; above that, Mailchimp is cheaper ($270/mo vs $400/mo at 25K). For ecommerce doing real revenue, Klaviyo justifies the premium. For newsletters and non-commerce email, Mailchimp — or better yet MailerLite — is more sensible.

Our pick: Klaviyo (7.5/10 vs 6.5/10)

Klaviyo wins 3 out of 6 categories. Mailchimp is better for: complete beginners who want the easiest interface and maximum third-party integrations.

Pros & Cons

Mailchimp

Genuinely intuitive interface — G2 rates ease of use 4.3/5, Capterra 4.4/5. The drag-and-drop builder has a shallow learning curve for basic campaigns
300+ third-party integrations — the largest ecosystem of any email tool. Nearly every SaaS product connects to Mailchimp natively
260+ professional templates on paid plans. The email builder produces clean, responsive emails that look good on mobile
Free plan has been systematically gutted: 2,000 contacts (pre-2021) → 500 (2023) → 250 (Jan 2026). Automations removed June 2025. A/B testing removed. Email scheduling removed. It is now effectively a demo, not a free plan
Charges for ALL contacts including unsubscribed and bounced — you pay for contacts who will never receive an email unless you manually archive each one. Most competitors only bill for active subscribers
Trustpilot: 2.7/5 with 67% one-star reviews. Support is widely despised — phone support only available on the $350+/month Premium plan. Below that, users report chatbots and generic responses

Klaviyo

Market-leading ecommerce segmentation with nested conditions, real-time updates, and predicted metrics — no other ESP matches this for Shopify stores
Revenue attribution that shows clear ROI per campaign and per automation flow — users cite this as what justifies the premium price
Deepest Shopify integration available with real-time data sync, product feeds, and browse/cart abandonment triggers
Gets expensive fast: $150/mo at 10K contacts, $400/mo at 25K, $720/mo at 50K, $1,380/mo at 100K — significantly more than every competitor
February 2025 billing change: now charges for ALL active profiles including unengaged subscribers, spam signups, and abandoned checkout contacts. Widely viewed as a post-IPO revenue grab
Trustpilot rating of 1.9/5 from 348 reviews — the worst of any tool we reviewed. Support is slow, no phone option, and declining post-IPO as they chase enterprise clients
