How A/B Testing Works
Create variants with different inserts and set percentage allocations. Insertr randomly assigns each qualifying order to a variant—or to the control group that receives nothing. Track which variant drives more repeat purchases.
Stop guessing which inserts work. Insertr's built-in A/B testing lets you compare different inserts head-to-head, with automatic control groups and statistical significance calculations.

No spreadsheets required. Insertr automatically calculates whether results are statistically significant at 95% confidence. You'll know when you have a real winner—not just random noise.
What You Can Test
Compare a discount card vs. a free sample. Test a handwritten thank you vs. a printed card. Try different offers or messaging. Each test reveals what resonates with your customers.

Run until you reach statistical significance—typically 100+ orders per variant. Insertr tells you when results are meaningful, so you don't have to guess. For most stores, this takes 2-4 weeks.
What's a control group?
The control group receives no insert. This lets you measure whether inserts actually drive more repeat purchases compared to doing nothing. If your variants total less than 100%, the remainder automatically becomes your control group.
