Personalization has evolved from a niche tactic into a core pillar of modern digital marketing, with 87% of brands planning to increase their investment over the next year. Despite widespread adoption, a significant gap exists between perceived and actual maturity—most marketers self-report as advanced, yet data reveals persistent challenges around disconnected tools, siloed data, and measurement. AI is accelerating progress, with 93% of brands and 94% of agencies agreeing it improves personalization, though only one in five have fully integrated it across channels. The findings highlight a growing divide between marketers who can execute personalization at scale and those still held back by foundational gaps in data infrastructure and cross-channel orchestration.
