I built an intelligent mail automation system that streamlined business communication by eliminating manual scheduling, sending, and tracking of email campaigns. Using n8n, integrated with Google Sheets and the Gmail API, I designed the solution to automatically retrieve updated contact data and content, apply custom business rules, and dispatch personalized mails with precision timing.

To ensure transparency, I built the system to log each transaction back into Google Sheets, enabling full auditability and real time campaign visibility without manual reporting. It dynamically adapts to spreadsheet updates, respects Gmail's send limits, and ensures enterprise grade deliverability with 99.9% accuracy.

By controlling everything through the familiar Google Sheets interface, I empowered business teams to run campaigns independently, without technical bottlenecks. This automation reduced the customer success team's workload by 85%, improved delivery performance, and created a scalable, low maintenance solution ready for future growth.
