Offroad Zone is a fully automated email validation and engagement system built with n8n to clean, verify and actively maintain a large legacy client email database. The system consists of three coordinated workflows. The first workflow validates client emails and updates their real delivery status in the backend. The second workflow continuously monitors and analyzes real user replies using AI to update engagement status and reasons. The third workflow acts as an automated email sending engine that targets users based on their validated and engagement-based status.
