Postscript review: AI retention marketing platform for SMS, RCS, and Email.

What Postscript does

Postscript is a retention marketing platform designed to help ecommerce stores scale their customer engagement through SMS, RCS, and Email channels. It provides a suite of tools including a visual flow builder with automation templates for cart abandonment and upsells, subscriber acquisition tools like popups and checkout collection, and advanced segmentation using Shopify data.

The platform operates on a paid model, starting with a 30-day free trial that includes a $100 credit. The Starter plan is $0 per month but requires a $49 monthly minimum spend, with per-message rates applied. The Growth plan costs $100 per month, and the Professional plan is $500 per month, offering lower per-message rates and additional features like API access and priority support. An Enterprise tier is available with custom pricing, and a dedicated Postscript AI Plan is offered at $699 per month. Carrier fees are passed through at cost. Users should note character limits: 160 characters for SMS without emojis, 70 with emojis, and up to 1,600 characters for MMS.

Our take

Postscript is well-suited for ecommerce brands looking to build and scale their SMS and email marketing efforts with advanced automation and segmentation. Its transparent pricing and lack of profile fees make it appealing for growing lists. However, it may not be the best fit for very small businesses due to the $49 monthly minimum spend on the entry-level plan and the costs associated with high-volume messaging.
