KLAVIYO SMS.
While Klaviyo is the gold standard for email, SMS marketing suffers from low international deliverability, strict character limits, and high carrier fees. WhatFlow gives your Shopify store the global reach and interactive power of WhatsApp while integrating seamlessly with your Klaviyo segments.
