Pros & Cons

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

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
