About
Postscript
Postscript is the SMS marketing platform built exclusively for Shopify, which means the integration is native rather than bolted on. Subscriber segmentation pulls directly from Shopify order data, compliance is handled by default, and two-way conversational texting lets your support and sales team engage in real threads rather than broadcast blasts. The focus is narrow by design: if you also want email in the same tool, look at Klaviyo. But if SMS is your primary retention channel and you are on Shopify, Postscript is the most operator-friendly option in the market. Pricing scales with subscriber count, and the free tier is generous enough to validate the channel before committing.
Attentive
Attentive is the SMS and email platform of choice for mid-market and enterprise e-commerce brands. Its two-tap mobile opt-in is the fastest list-building mechanism in the category, and AI-driven send-time optimisation consistently delivers click rates in the 20–30% range that email can rarely match. The platform is deep but not cheap: expect enterprise pricing and a proper onboarding process. It is not the right fit for stores under $500K in annual revenue, where Postscript or Klaviyo SMS will give you 90% of the capability at a fraction of the cost. For brands ready to invest in SMS as a serious revenue channel, Attentive is the benchmark.
