Different jobs
Intelligems maximizes visitor land through post-purchase.
Many brands run both. Intelligems owns the experiments — merchandising, pricing, shipping, checkout, post-purchase and content — and the profit analytics to measure impact.
Full-funnel testing
Every lever in your funnel.
- Price test individual SKUs, bundles, and collections
- Ship rate experiments — free threshold, flat rate, carrier rules
- Checkout extensibility — upsells, fields, and layout
- Post-purchase offers tied to the completed order
- Content and theme tests alongside transactional tests
- A/B/C/D/E — up to five variants in a single experiment
- Rebuy's A/B testing is built for its own Smart Cart and flow surfaces — not for testing prices or shipping rates
