Postscript review

Postscript is the most store-focused texting tool on this list. Every plan includes a visual flow builder with templates for cart and browse abandonment, welcome series, upsells and shipping updates, plus popups, checkout collection and its Onsite Opt-in for list growth. Segments use Shopify data and third party integrations, and you can answer customer replies from the same account. Pricing is usage-based: 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 a month cuts the SMS rate to $0.008 and unlocks unlimited keywords and live chat support, while Professional at $500 adds API access and enhanced analytics. A dedicated toll-free number is included and verified for free, and a short code costs the carriers' $750 a month at no markup. The main limit is the Shopify focus: brands on other platforms must add Postscript's SDK to their store code.
