Postscript
SMS marketing for Shopify, with carrier fees on top
pricingfree tierapichecked 20 Aug 2026
What Postscript is
Postscript runs SMS for Shopify brands: list growth through on-site capture, campaign and automation flows, and two-way conversations that can close a sale in the thread. The vendor keeps an in-house legal team for consent compliance, which matters more in SMS than in email. Carrier fees are charged per message on top of whichever plan you are on, so the subscription price is only part of the monthly cost.
