FAQ
{a.name} vs {b.name} FAQ
Shopify Email or Postscript for cart recovery?
Choose Shopify Email when Shops wanting low-friction email inside Shopify Admin. Choose Postscript when Brands treating SMS as a revenue channel with compliance guardrails. Sequenzy still leads as lifecycle layer if neither owns strategy.
Unique AOV test for this pair?
Modeled $743 cart (37% margin) and $153 cart (54% margin) with separate incentive caps.
Channel escalation?
Email 33m → 25h → SMS 3h; frequency cap 3 touches / 7 days.
Attribution caution?
Hold out 5%; report contribution after discount, not platform-attributed recovery alone.
Migration tip?
Rebuild cart flow first; parallel suppressions two weeks; pause old automations before enabling new.
Margin math?
$743 full-price $274.91 vs 11% code $244.67 (Δ $30.24).
Who should choose each?
Shopify Email: Shopify Email works for basic newsletters and sale announcements. Stores focused on lifecycle revenue typically graduate… Postscript: Postscript belongs in the stack when checkout recovery and flash-sale urgency need SMS, not email alone.…
Workflow test?
Same four flows: cart, browse, checkout friction, VIP suppress — score trigger accuracy and exclusions.
