Comprehensive Validation
Every email goes through multiple validation checks
Checks if the email address is properly formatted according to RFC standards.
Verifies the domain exists and has valid MX records configured.
Connects to the mail server to verify the mailbox actually exists.
Identifies temporary and disposable email addresses from known providers.
Flags generic role-based emails like info@, support@, or admin@.
Identifies domains configured to accept all emails regardless of validity.
Clear Result Categories
Every email is categorized for easy decision-making
Safe
Email is valid, deliverable, and safe to send. The mailbox exists and accepts emails.
Risky
Email might be valid but has risk factors like being disposable, a catch-all domain, or role-based.
Invalid
Email is definitely invalid. The mailbox does not exist or the domain is invalid.
Unknown
Could not determine validity due to server issues or configuration that prevents verification.
