Email Checker
Verify if an email address is valid and exists
How does email verification work?
Our tool verifies the email format, checks that the domain exists, and that it has mail servers (MX records) configured.
This helps identify invalid addresses without sending real emails, although we cannot guarantee 100% that an email exists without sending a real message.
It performs three levels of validation: format, domain existence, and MX records verification.

Can I know if an email exists 100%?
It's not possible to confirm 100% that an email exists without sending a real message. However, our verification helps you detect clearly invalid addresses (incorrect format, non-existent domain, no mail servers).
What are MX records?
MX (Mail Exchange) records are DNS configurations that indicate which servers are authorized to receive emails for a domain. If a domain has no MX records, it cannot receive emails.
