Klaviyo is a powerhouse for e-commerce email and SMS marketing, with best-in-class Shopify integration and predictive analytics that justify its premium positioning. However, the platform tells two very different stories depending on where you look.
On G2 and Capterra, daily users rate it 4.6/5 — praising its deep segmentation, automated flows, and real-time data sync. On Trustpilot, the score plummets to 1.9/5, driven almost entirely by frustration over the "active profiles" billing model introduced in February 2025, which charges for all stored contacts rather than just those you email.
Our verdict: Klaviyo is genuinely excellent software for mid-to-large e-commerce brands generating $10K+/month in email revenue, where the ROI clearly justifies the cost. But smaller stores or those with large inactive lists should carefully model their costs before committing — the billing structure can create unpleasant surprises.
