High-Level Overview & Strategic Impact
Merging basic `{{First_Name}}` tags is no longer considered personalization. Modern email personalization happens at the moment of open (open-time rendering), dynamically generating 1:1 personalized product grids, live countdown timers, localized currency pricing, and weather-dependent imagery based on the subscriber’s exact location and real-time CDP intent.

Why static emails fail to drive conversions:
