Automated Email Validation and Domain Extraction Workflow

This n8n workflow automates email validation and domain extraction from email addresses. It is designed to be triggered manually via the “Test workflow” button, making it ideal for testing or ad-hoc processing. The process begins with a placeholder for data input, represented by a ‘Generate random data’ node, which in practice should be replaced with your actual email data source.

Once activated, the workflow passes the email data through a set of processing nodes. The ‘Set’ node performs two key actions: it validates whether the email address is correctly formatted using the ‘isEmail()’ function, and it extracts the domain part of the email address with the ‘extractDomain()’ method. These results are stored in designated fields.

This setup is particularly useful in scenarios such as email marketing lists, customer onboarding systems, or database cleansing where verifying the authenticity of email addresses and understanding their domain origins are crucial. It allows users to test email addresses quickly and extract key information for further processing or filtering.
