How to use Postscript

Getting started with Postscript is a streamlined process designed for quick integration and rapid results. First, install the Postscript app from the Shopify App Store and connect it to your store. Next, begin building your subscriber list using a suite of powerful acquisition tools, such as customizable popups, keywords for text-to-join campaigns, QR codes, and checkout page opt-ins. Once you have a list, use the intuitive drag-and-drop Flow Builder to create automated message series for various customer journey touchpoints, like welcome series, abandoned cart reminders, and shipping notifications. You can also send one-off campaigns for promotions or announcements. Leverage Postscript's AI, including the AI Shopper and Infinity Testing, to optimize message copy, timing, and offers for maximum engagement and revenue. Finally, manage two-way conversations directly within the platform to provide support and close sales.

Use Cases for Postscript

Postscript is versatile and can be applied across the entire customer lifecycle. For customer acquisition, brands use text-to-join keywords on social media and packaging. To drive conversions, automated abandoned cart reminders with personalized offers are highly effective. For retention, post-purchase flows can include shipping updates, review requests, and loyalty offers. During promotional periods like Black Friday, brands can send targeted campaign blasts to segmented lists for flash sales. The AI Shopper can act as a personal stylist, recommending products to customers via text. Additionally, back-in-stock automations capture high-intent subscribers for popular items, turning a potential lost sale into a future conversion.

Advantages of Postscript

Postscript's primary advantage is its singular focus on SMS for Shopify, which translates into unparalleled expertise and a deeply integrated product. Unlike all-in-one marketing platforms, its specialized approach ensures every feature is optimized for SMS success. The platform's powerful AI capabilities, particularly Infinity Testing, provide a significant competitive edge by automating optimization at a scale humans cannot match. Its commitment to compliance, backed by an in-house legal team, gives merchants peace of mind. Furthermore, Postscript's proven ability to generate high ROI (34x on average) and rapidly grow subscriber lists makes it a powerful engine for sustainable e-commerce growth.
