๐Ÿšซ Email Unsubscribe Handler for Outlook

Description
This n8n workflow automatically scans recent email replies from your Outlook inbox and identifies unsubscribe requests. If a contact replies with any variation of "unsubscribe" within the past 7 days, the system performs two key actions:

Saves the contactโ€™s email address in a BigQuery unsubscribes table (for compliance and tracking).

Deletes that contact from the active leads table in BigQuery (to stop future outreach).

This flow can be triggered on a schedule (e.g. every 4 hours) or run manually as needed.

Key Features
๐Ÿ“ฅ Email Parsing from Outlook: Automatically monitors for replies that contain unsubscribe language.

๐Ÿง  Smart Filtering: Captures unsubscribes based on message content, not just subject lines.

๐Ÿ”„ BigQuery Integration: Logs unsubscribed emails and removes them from your leads dataset.
