Postscript review

Postscript is the most store-focused SMS tool here, and its pricing reflects that. Starter has no subscription fee but a $49 monthly minimum spend, with SMS at $0.009 and MMS at $0.045 plus carrier fees. Growth at $100 per month lowers the message rate, unlocks unlimited opt-in keywords and adds live chat support, and Professional at $500 per month adds enhanced analytics, API access and removes the Postscript badge from opt-ins. Every plan includes a visual flow builder with cart and browse abandonment, welcome, upsell and shipping templates, popups and checkout collection, Shopify-based segmentation, response management and a dedicated toll-free number. Postscript now also sends RCS and email, and its AI Plan at $699 per month adds Infinity Testing and Shopper journeys. The fit is narrow on purpose. Brands outside Shopify, or businesses that mainly send reminders and local offers, will find SimpleTexting or EZ Texting easier.

Who it is for

Shopify stores that want text flows driven by order and browsing data.
