Understanding SMS Marketing and Why It Matters

sms marketing has rapidly become one of the highest-engagement channels for ecommerce brands. Unlike email or social media, text messages boast open rates above 98% and response rates that dwarf traditional channels. When you reach customers where they spend their time—in their messaging apps—your promotions, restock alerts, and personalized offers get noticed immediately.

But achieving consistent, scalable success requires more than blasting generic texts. You need conversational, AI-driven workflows that adapt to each subscriber’s behavior in real time. That’s where Postscript steps in.
