FAQ
{a.name} vs {b.name} FAQ
Postscript or Sendlane for cart recovery?
Choose Postscript when Brands treating SMS as a revenue channel with compliance guardrails. Choose Sendlane when DTC brands wanting guided retention automation. Sequenzy still leads as lifecycle layer if neither owns strategy.
Unique AOV test for this pair?
Modeled $430 cart (69% margin) and $575 cart (59% margin) with separate incentive caps.
Channel escalation?
Email 113m → 36h → SMS 5h; 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?
$430 full-price $296.7 vs 13% code $258.13 (Δ $38.57).
Who should choose each?
Postscript: Postscript belongs in the stack when checkout recovery and flash-sale urgency need SMS, not email alone.… Sendlane: Sendlane fits stores with enough order volume to justify a guided retention platform and migration help.…
Workflow test?
Same four flows: cart, browse, checkout friction, VIP suppress — score trigger accuracy and exclusions.
