SMS marketing platform versus storefront conversion and list growth tool
Postscript is better when you already have an audience and want SMS campaigns or SMS automations. Privy is better when the problem is capturing more emails and phone numbers from storefront traffic. Choose Postscript for SMS execution. Choose Privy for popups, forms, and conversion tools. Choose Sequenzy when you want the email automation layer after subscribers are captured, especially for Shopify, WooCommerce, Stripe, campaigns, and transactional email.
The main things that set these tools apart
Privy is most useful when the store needs to convert visitors into subscribers through popups, offers, and forms.
Postscript is most useful once you have SMS consent and want to run text campaigns or automated SMS flows.
After subscribers enter the list, Sequenzy can run email campaigns, automations, cart recovery, post-purchase flows, and transactional messages.

When to choose each tool
If forms already work, adding another popup tool will not fix weak lifecycle email. Sequenzy focuses on the email follow-up.
Postscript is useful for SMS, but not every store should add SMS before cart, order, newsletter, and win-back email are solid.
Sequenzy supports both store platforms for core email automation, which matters if you manage more than one type of ecommerce setup.
Privy helps you build the list. Postscript helps you text the list. That distinction matters more than feature-by-feature comparison.
Sequenzy fits after capture. It helps Shopify and WooCommerce stores send better email flows, campaigns, transactional messages, and lifecycle emails without making SMS the default next purchase.
