An automated API synchronization layer and light-themed analytics workspace connecting email performance and sync health with Google Sheets.
Context
What needed to improve.
The challenge
Email activity lived outside the client’s reporting sheet, requiring repeated manual updates and making engagement history harder to analyze.
Constraint
Campaign and subscriber data came from external API endpoints
Constraint
Source fields needed safe mappings into Sheet columns
Constraint
The team needed visible synchronization health and recoverable errors
The system
One clear path through the moving parts.
