Gmail to Database Operations
Normalizes email events, classifies priority and stores messages plus attachments without duplication.
01 / Problem
Operational inboxes mix important messages, attachments and repeated events in one unstructured stream.
02 / System
Designed as a controlled operational pipeline.
An importable n8n workflow converts Gmail events into normalized database rows, assigns deterministic category and priority, stores attachments and creates alerts.

One email row and two attachment rows
02
Priority-aware notification
03
Replay creates no duplicates
03 / Reliability controls
