Postscript

Postscript's automation builder handles the standard cart-abandonment and win-back flows most ecommerce brands want, plus segmentation and on-site popups for growing a subscriber list, but its two-way messaging is built for actual conversation rather than one-directional blasts. A shopper who texts back a question can get routed to a real response, not just an unsubscribe keyword parser.

The Starter plan is free with no monthly fee, and you pay per message instead, around $0.015 per SMS and $0.045 per MMS, which keeps the entry cost low compared to Attentive's minimum commitments. Growth, at roughly $25 a month, and Professional, near $500 a month, add automation depth, AI tools, and dedicated support as volume grows. A 30-day trial includes $100 in messaging credit to test the platform before committing. Postscript suits a smaller or mid-size ecommerce brand that wants Attentive-style two-way SMS without the quarterly minimum spend.
