Organize Email Attachments into Google Drive Folders by Company

This n8n workflow automatically processes emails labeled in Gmail that contain attachments, extracting and organizing them into structured Google Drive folders based on the sender's company. It first triggers on new labeled emails, retrieves attachments, and cross-references the sender's email against a whitelist maintained in Google Sheets to ensure only verified sources are processed. Files are then uploaded to company-specific folders (e.g., by company name and date) with unique timestamps to avoid overwrites.

Key benefits include massive time savings on manual file sorting, reduced errors from disorganized storage, and enhanced security through sender validation. Ideal for teams handling invoices, receipts, client documents, or any high-volume email attachments, it eliminates cluttered inboxes and ensures compliance-ready organization.

Use cases span enterprises like accounting firms sorting vendor invoices, sales teams archiving proposals, or legal practices managing contracts. Setup requires Gmail labels, OAuth credentials for Gmail/Drive/Sheets, and a simple whitelist sheet—deployable in minutes for ongoing automation.
