In this deep-dive article, I’ll break down their features, pricing, real-world performance, and more—based on fresh data and user experiences—to help you decide.

I’ve run an e-commerce side hustle for years, experimenting with various marketing tools. From my firsthand trials and analyzing hundreds of reviews, Attentive shines for multi-channel scalability, while Postscript excels in Shopify-native simplicity. But let’s get into the details.

Understanding SMS Marketing in 2026

SMS marketing has evolved dramatically by 2026. With open rates hitting 98% and response rates at 45%, it’s no wonder brands are shifting budgets here. Texts aren’t just alerts anymore—they’re conversational, AI-driven experiences that boost average order value (AOV) and lifetime value (LTV).

In this landscape, Attentive and Postscript stand out. Both leverage AI for personalization, but their approaches differ. Attentive integrates SMS with email and RCS (Rich Communication Services), making it ideal for omnichannel strategies. Postscript, meanwhile, focuses laser-sharp on SMS for Shopify stores, emphasizing compliance and quick wins.

Why compare them now? E-commerce is projected to grow 15% annually, and SMS drives 73% of marketers’ incremental revenue. Choosing the wrong platform could mean missed sales or compliance headaches.
