Do I have server-side tracking to reduce signal loss on iOS?

Question

As an e-commerce merchant dealing with increasing iOS privacy restrictions, I'm struggling to track conversions accurately. Apple's App Tracking Transparency (ATT) and limitations on third-party cookies have made traditional tracking methods unreliable. I need to understand how server-side tracking can help me maintain data integrity, reduce signal loss, and continue making informed marketing decisions in this privacy-first environment. What strategies can I implement to ensure I'm not losing critical conversion data?

Should I Allow Discount Code Stacking to Increase Conversion?
Discount code stacking lets customers combine multiple discounts, which can meaningfully increase conversion - especially for visitors who are comparing your total cost against competitors. However, uncontrolled stacking can destroy margins when customers discover they can combine a loyalty reward + seasonal discount + influencer code + sitewide sale into a 40-50% total discount.
