Flag Bounced Emails in Google Sheets from Gmail Errors

This n8n workflow monitors your Gmail inbox (including spam) for delivery error notifications, such as bounced emails from failed campaigns. Upon detecting these errors, it parses the email content to identify problematic email addresses, looks them up in your Google Sheet (used for campaign lists), and updates a 'flagged' status to prevent resending to invalid addresses.

Key benefits include improved email deliverability, reduced bounce rates, and time savings by automating manual error checking. It's especially valuable for recurring email campaigns, ensuring cleaner lists without manual intervention and complying with best practices to avoid spam filters.

Ideal use cases: Marketing teams running personalized campaigns, HR for employee communications, or sales for lead nurturing. Requires a prerequisite email campaign workflow and a specific Google Sheet template. Setup involves configuring Gmail credentials, Sheet ID, and search labels for error emails.
