ShipSplit

ShipSplit lets you A/B test shipping options on real shoppers. Split checkout traffic between strategies — free shipping, a flat rate, or free over a set amount — and compare conversion rate, order value, and net profit for each, with a confidence score. Test several free-shipping thresholds at once and compare them. See results by destination country and apply a different winning option per country. Make the winner your store default, or let Autopilot apply it.
