Email validators typically work by performing a series of checks to confirm the validity of an email address. Some of the checks include:
Syntax Check: Ensures the email address follows the standard format (e.g., user@domain.com). Domain Check: Verifies if the domain name exists and can receive emails. MX Record Check: Confirms that the domain has valid MX (Mail Exchange) records set up to accept emails. Role-Based Account Detection: Identifies generic roles like info@ or admin@ that may not be suitable for personalized email marketing.
