Noah Adelstein breaks down what actually works in outbound personalization. Skip generic details like schools or pets, and tie messaging to the value you provide. Start with one campaign, one hypothesis, and your sales team’s input on who to target. Layer in accurate data, from de-anonymized traffic to job changes and funding signals, then build your own triggers as common ones get crowded. Weigh audience size against effort, and remember billboards make ROI nearly impossible.
