Frequently Asked Questions

How does post-checkout upsell work?

After a customer completes payment, an upsell offer appears. Since payment info is already on file, they can accept with one click without re-entering card details. This eliminates abandonment risk.

How does post-purchase email upselling work?

After a customer completes an order, the app automatically sends an email featuring products related to their purchase. You can set the timing (2 weeks, 1 month, etc.) to find the optimal delivery window.
