- What A/B test metrics are available beyond open and click rates?
- Are the email designs mobile-first, desktop-first, or both?
### What a Strong Answer Covers

- A test plan with primary metric, guardrails, segmentation, and statistical checks.
- A decision framework for email A/B results based on downstream value and trust.
- UX critique around clarity, savings credibility, CTA hierarchy, merchant branding, accessibility, and mobile layout.
### Follow-up Questions
- How would you measure whether coupon recommendations are trustworthy?
