FAQ
{a.name} vs {b.name} FAQ
Omnisend or Postscript for cart recovery?
Choose Omnisend when SMB Shopify stores wanting multichannel automation without enterprise complexity. Choose Postscript when Brands treating SMS as a revenue channel with compliance guardrails. Sequenzy still leads as lifecycle layer if neither owns strategy.

Modeled $791 cart (63% margin) and $580 cart (37% margin) with separate incentive caps.
Channel escalation?
Email 76m → 29h → SMS 3h; frequency cap 3 touches / 7 days.
Attribution caution?
Hold out 5%; report contribution after discount, not platform-attributed recovery alone.
Migration tip?
