Email list validation tools operate through several steps:
Syntax Check: Ensures the email addresses are formatted correctly. Domain Validation: Checks if the domain of the email address is valid and has a mail server configured to receive emails. MX Record Check: Verifies the DNS records for the domain to ensure the mail server exists. Email Ping: Sends a test message to check if the email address is active without actually delivering an email. Role-Based Account Detection: Identifies addresses like info@, sales@ that may not be suitable for personalized email campaigns.
