Built an automated email validation workflow using n8n to process and verify email addresses at scale.
The workflow fetches user email data via an API, sends each email to a third-party email validation service, and updates the validation status (valid, invalid, risky, etc.) back into the database automatically. It is designed to efficiently handle large volumes of users with minimal manual intervention.
Automation Summary
Developed an automated Email Validation Workflow using n8n to verify and maintain email data accuracy at scale. The system automatically fetches user emails via backend APIs, validates them using a third-party email verification service, and updates validation statuses back into the database. This automation significantly improves email deliverability, reduces bounce rates, and eliminates manual data cleaning for large datasets.
- Automated validation of large email datasets
- Integration with third-party email validation services
- Backend API-driven database updates
- Scalable n8n workflow for bulk processing
- Improved data quality and email deliverability
-
Many databases contain a large volume of email addresses, but over time it becomes unclear which emails are still valid and deliverable and which have become deprecated, inactive, or invalid. This leads to poor email deliverability, higher bounce rates, and wasted resources during communication campaigns.

Designed and implemented an automated email validation workflow using n8n to continuously verify and update email statuses at scale. The workflow fetches email addresses from the database via a backend API, sends them to a third-party email validation service, and updates each user’s email status (valid, invalid, risky, deprecated, etc.) back into the database automatically. The system is optimized to handle large datasets efficiently with minimal manual effort.
