ActiveCampaign vs Klaviyo

ActiveCampaign and Klaviyo are both power tools — but for different use cases. ActiveCampaign is the automation king: 135+ triggers, 750+ recipes, built-in CRM, and it works for any business type. Klaviyo is the ecommerce king: Shopify-native, revenue attribution, predictive analytics, and the deepest product-based segmentation available. If you run ecommerce, Klaviyo wins. If you run a service business, agency, or SaaS, ActiveCampaign wins. The wrong choice here will cost you.

Our pick: Klaviyo (7.5/10 vs 7.4/10)

Klaviyo wins 2 out of 6 categories. ActiveCampaign is better for: mid-sized businesses (1k-25k contacts) that actively use complex automation daily.

Pros & Cons

ActiveCampaign

Best-in-class automation builder with 135+ triggers and 750+ pre-built recipes — no other platform matches this depth (G2: 4.5/5 from 14,000+ reviews)

900+ integrations including 40+ new ones added in 2025 alone (Wix, Webflow, SOCi) — plays nicely with almost anything

Deep segmentation with new AI Segments Agent that lets you describe audiences in natural language

Aggressive price hikes documented at 20-100% for existing customers. Real examples: $588/yr to $1,800/yr; $1,400/mo to $2,800/mo; $2,000/yr to $7,800/yr

As of November 2025, now charges for ALL contacts including unsubscribed, bounced, and unconfirmed — same controversial practice as Mailchimp

Trustpilot rating of 2.8/5 from 1,358 reviews — billing complaints, cancellation horror stories, and users charged after cancelling

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
