Choose Postscript if
- Shopify stores where SMS already converts and volume justifies the minimum
- Teams segmenting on store data rather than a separate list
Choose Shopify Sidekick if
- Stores that want AI copy without another subscription
Where each one disappoints
Postscript
- Anyone reading $0 as free — the Starter plan sets a $49 monthly minimum before carrier fees
Shopify Sidekick
- Anyone needing brand-voice control — depth is limited
