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.
Smartly.io
Running paid social at scale across Meta, TikTok, and Google simultaneously is operationally brutal. Smartly.io exists to absorb that complexity. The platform automates creative production, bid adjustments, and budget reallocation in real time, reducing the manual loop that eats up media buyer hours. It's built for teams spending meaningfully on paid social, not solo operators testing small budgets. The creative automation features are particularly strong: dynamic templates can pull product catalogue data and generate hundreds of ad variants without a designer in the loop. Agencies and in-house growth teams at mid-market and enterprise brands are its natural home.
