04Is Postscript worth the money?
Postscript’s range—SMS, RCS, email, journeys and testing—makes it broader than an SMS-only tool, but the listed plan prices don’t tell the whole bill. Starter’s $49 minimum spend, per-message charges, pass-through carrier fees and possible short-code rental make volume and message mix matter. The $699 AI Plan adds specified AI products but still lists variable per-message rates. It may fit a retention program that needs those capabilities; compare total message costs, not just monthly plan fees.
