Automated Email Validation and Verification Workflow

This n8n workflow automates the process of verifying and validating email addresses from a Google Sheet, enhancing lead data quality. It begins by fetching email data from a specified Google Sheet, then cleans and prepares the input data by filtering out invalid emails and extracting relevant contact information. Each valid email is then sent to Hunter.io for verification via their API, which returns detailed metadata including status, score, SMTP checks, and other useful indicators. The workflow then processes and formats the Hunter.io response, providing a clear summary of each email’s validity. Finally, the enriched verification results are appended or updated in an output Google Sheet.

This workflow is triggered automatically on a daily schedule, making it ideal for lead management, email list cleaning, or marketing campaigns where accurate contact data is crucial. By integrating Google Sheets and Hunter.io, it streamlines the data validation process, saving time and reducing manual effort while increasing email deliverability rates.
