Postscript pricing is SMS-first
Postscript pricing should be evaluated by SMS subscriber growth, campaigns, automations, message volume, and carrier cost assumptions.
The expensive part of SMS is rarely the plan name. It is message volume, MMS use, carrier fees, compliance, and how often the store sends promotional campaigns or triggered flows. Postscript can be a revenue channel for ecommerce teams, but it should not be treated as a replacement for email lifecycle software unless SMS is genuinely the center of the retention strategy.
