Struggling to make your SMS channel a top revenue driver? Many brands send messages that don't convert, wasting customer attention. Postscript tackles this by focusing solely on SMS, using AI to send smarter messages that shoppers actually engage with. Their focus is on generating real, trackable ROI from every text.

The promise is a dedicated team and technology working together to make your SMS list your most valuable asset. They claim a 34x return on investment on SMS spend for their merchants. This isn't an add-on; it's their entire business.

The service combines specialized software with a strategic team of SMS experts. Their goal is to transform your list into a reliable, high-ROI revenue stream through compliant and effective messaging.

Should you choose Postscript?

Quick buyer guidance before you compare plans or click through.

Choose it if

  • Established Shopify stores (typically $500k+ annual revenue) that want to make SMS a primary revenue channel and can justify a $100–$500/month platform fee plus per-message costs
  • DTC brands that need deep SMS-specific expertise and strategic guidance rather than a generic multi-channel tool, and who value Postscript's dedicated team support
  • Merchants who prioritize TCPA and carrier compliance and want an in-house legal team managing opt-in, opt-out, and messaging regulations
  • Brands planning high-volume messaging who benefit from AI-driven optimization like Infinity Testing to maximize campaign ROI without manual A/B testing

Skip it if

  • Stores on platforms other than Shopify (e.g., WooCommerce, BigCommerce) — Postscript is built exclusively for the Shopify ecosystem, and the custom SDK route is not a standard supported connector
  • Very early-stage or low-revenue brands with tight budgets, since the Growth plan starts at $100/month plus per-message and carrier fees, and the Starter plan carries a $49 minimum monthly spend
  • Teams seeking an all-in-one marketing suite — email, push, and social channels require separate tools, adding cost and integration overhead
  • Brands that only send occasional, low-volume texts and won't recoup the platform fee through SMS-driven revenue

Next steps before buying

  1. 1Start the 30-day free trial with the $100 credit (covers message and carrier fees) by signing up at postscript.io and installing the Postscript app from the Shopify App Store
  2. 2Set up your compliant opt-in methods first — use the Popup Editor or Onsite Opt-In to capture subscribers, and submit any existing list via their form for Compliance Team review before messaging
  3. 3Build your first automations (welcome series, abandoned cart, browse abandonment) and segments, then let Infinity Testing optimize message variants before scaling to campaigns
  4. 4Choose a plan based on projected send volume — Starter ($0/mo with $49 min spend) for testing, Growth ($100/mo) or Professional ($500/mo) for scaling, and contact sales for Enterprise or a dedicated short code ($750/month) if you need high-volume sending

Ease of use

The platform is built for Shopify, suggesting a streamlined integration. They emphasize a 'world-class' editor for popups and opt-ins, aiming for ease of list building. Combined with dedicated strategy support, it appears designed to reduce the learning curve for effective SMS marketing.

Postscript Key Features

✨ Turn SMS Into Your Top Revenue Channel

Postscript is built for one thing: making SMS your most profitable marketing channel. Their entire focus is on SMS strategy and technology. This dedicated approach helps Shopify stores see more success than with general marketing tools.

They combine deep ecommerce expertise with conversational AI technology. This combination transforms your text list from a simple broadcast tool into a real, high-ROI revenue stream. The platform and their expert team work together to ensure every message moves your business forward.

✨ Grow Your List 3x Faster

A bigger, engaged subscriber list is the foundation of SMS revenue. Postscript provides world-class tools designed specifically for rapid, compliant list building. Their Popup Editor, CashBack, and Onsite Opt-In are engineered to help you grow faster than anywhere else.

The Onsite Opt-In feature has led to a documented 50% increase in conversion rates for merchants. This focus on first-party data collection is key to building a direct, valuable relationship with your customers through text.

✨ Send Smarter Messages with AI-Powered Optimization

Move beyond simple A/B testing with Postscript's AI technology. Their Infinity Testing feature can test hundreds of on-brand message variants automatically. This finds the highest-performing content in a fraction of the time it would take manually.

The AI learns and adapts to generate a higher return on investment for every message you send. It's about ensuring every campaign and automation performs at its absolute peak, driving measurable results.

✨ Have Real Conversations That Drive Sales

Postscript helps you unlock the power of meaningful customer engagement. Their always-on 1:1 shopping assistant instantly answers customer questions. This conversational approach builds trust and drives sales through helpful interactions.

This feature turns your SMS channel into an active part of the shopping experience. It helps resolve issues quickly and guides customers toward a purchase, creating a better overall experience.

Use Cases

🚀 Launching a New Product Collection

A Shopify brand wants to drive buzz and sales for a seasonal launch. Instead of relying on email alone, they use Postscript to build anticipation. They start with a 3-part SMS series.

The first message teases the drop. The second gives early access to SMS subscribers. The third announces the launch.

They use AI to optimize send times and copy for each segment. The result is a 40% higher open rate and immediate sell-through of key items.

💬 Abandoned Cart Recovery That Feels Human

Generic cart reminders often get ignored. A store integrates Postscript's conversational AI. When a customer abandons their cart, a friendly text asks if they had any questions.

The AI instantly answers common concerns about sizing or shipping. This 1:1 engagement recovers 15% more carts than their old automated email flow.

📈 Growing a Compliant Subscriber List

Problem: Building a large, engaged SMS list while staying compliant feels complex.

Approach: Use Postscript's built-in Popup Editor and Onsite Opt-In. These tools are designed to convert website visitors into subscribers. The platform's in-house legal team ensures every opt-in method meets strict regulations.

Expected outcome: Brands grow their list 3x faster. You start with a strong foundation for revenue.

⚡ Moving from Basic Blasts to High-Performing Campaigns

A team was sending the same SMS blast to their entire list. They switched to Postscript's Infinity Testing. Instead of a simple A/B test, they let AI test hundreds of message variants—different headlines, offers, and calls-to-action—automatically.

The system found the top performers for each customer segment. This shift increased their average campaign revenue by 22%.

🛡️ Ensuring Compliance and Avoiding Risk

For any brand, the legal side of SMS marketing is a major worry. Postscript builds compliance into its core. Their dedicated legal team navigates the complex regulations.

They provide tools for easy opt-in and opt-out management. This protects your business from fines and lets you focus on creating messages, not interpreting laws.

🤝 Getting Dedicated Strategy for Your Brand

You have the platform, but now what? Postscript pairs its software with a team of SMS experts. They act as an extension of your team.

They help craft your strategy, set up automations, and analyze performance. It’s not just a tool; it’s a partnership focused on making SMS your top revenue channel.
