The notion of periodic "refresh" cycles for marketing tech stacks is a myth fueled by hype, not necessity. Instead, marketers succeed with incremental updates and modular integrations, especially AI-driven ones for agility in 2025. This approach saves costs, boosts ROI, and enables continuous optimization without disruptions.
Google's Agent2Agent (A2A) protocol, launched in April 2025, enables seamless collaboration among AI agents from different providers, akin to HTTP for the internet. It transforms marketing by automating tasks like personalization and analytics, despite security challenges. Marketers must adopt it for efficient, hyper-personalized campaigns.
