About this tool
Verify Valid Email Address Free runs in your browser with no backend of its own. Verify Valid Email Address Free inspects the DNS-level deliverability signals for a domain directly from your browser.

The MX, SPF and DMARC checks are DNS queries sent from your browser to a public resolver; this site has no backend and never sees them, and a connection is required.
