Mailchimp vs Klaviyo

Mailchimp is the biggest name in email. Klaviyo is the biggest name in ecommerce email. They're not really competing for the same user — Mailchimp targets beginners and small businesses, while Klaviyo targets Shopify stores doing real revenue. The confusion comes from Mailchimp's marketing, which positions it as an ecommerce tool despite lacking the segmentation depth, revenue attribution, and predictive analytics that serious stores need. Let's cut through the marketing and compare what actually matters.

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: 2.8/5 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

Best-in-class 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 2.1/5 — the worst of any tool we reviewed. Support is slow, no phone option, and declining post-IPO as they chase enterprise clients
