Klaviyo SMS vs Attentive

Two ecommerce SMS heavyweights with different shapes. Klaviyo unifies email and SMS with self serve pricing that scales from a free plan; Attentive is a premium, managed platform built for high volume DTC brands. For most stores the unified, lower cost option wins; the largest senders may still prefer Attentive's scale.
