An n8n workflow automation that triages incoming Gmail messages by extracting sender, subject, and intent keywords, then routes them through IF-based classification. Billing emails create Notion follow-up pages, support requests generate Zendesk tickets, and unclassified messages are posted to a Slack ops channel — all with a centralized Google Sheets audit log.
