Postscript review

Postscript focuses on text messaging, so it suits brands whose customers respond better to a text than an email when they leave a cart. The Starter plan has a $49 monthly minimum spend, then charges $0.009 per SMS and $0.045 per MMS plus carrier fees, and includes campaigns, automations, unlimited segments, a unique toll-free number and subscriber acquisition tools. Growth costs $100 a month, lowers the SMS rate to $0.008 and adds unlimited opt-in keywords and live chat support, while Professional at $500 adds an onboarding specialist, a dedicated CSM and custom integrations. Every plan gets a $100 credit for the first 30 days. The listing describes patented Onsite Opt-in, an AI suite called Shopper and Infinity Testing that keeps flows improving. It ranks seventh on value: per-message fees make the final bill hard to predict, and the listing notes that email is still rolling out in phases, so most stores will pair it with an email app.
