What the data says
Klaviyo carries the rating edge (0.20 stars). Klaviyo added more reviews last year.
Both apps live in the same Shopify category but merchants describe them differently. Privy ‑ Email, SMS & Pop Ups reviewers disproportionately call out integration depth and predictable fulfillment; Klaviyo reviewers disproportionately call out provider choice and unit-cost pricing. The decision usually comes down to which one of those two failure modes hurts your business more.
