Product marketers are expected to validate messaging before launch, but many teams lack the time, budget, or access to formal research. This session presents a practical, real-world framework for message testing without research budgets, showing PMMs how to identify the meaningful variable in their messaging and validate it using tools they already have. Drawing from hands-on experience as a senior product marketing leader and fractional CMO, the talk covers how to test hooks, claims, and positioning through landing pages, ads, sales conversations, and behavioral signals—without over-interpreting noisy data. Attendees will leave with a lightweight, repeatable approach to message validation that builds confidence, speeds GTM decisions, and helps teams know when a message is ready to scale.
