EmailValidator tools typically use a combination of methods to verify email addresses:
Syntax Checking: Verifies if the email address follows the correct format. Domain Validation: Checks if the domain of the email address exists and is active. Mailbox Verification: Pings the email server to confirm that the email address is valid and can receive messages. Role-Based Account Detection: Identifies addresses that belong to a role (e.g., info@, sales@) rather than an individual, which may not be ideal for personalized marketing.
