About this tool
Bulk Email Verifier For Free is a static, browser-based client. Bulk Email Verifier For Free validates an address syntax locally, then checks the domain MX, SPF and DMARC records over DNS-over-HTTPS.
Proving a specific mailbox exists requires sending mail, which a browser cannot do, so Bulk Email Verifier For Free focuses on the DNS signals that genuinely can be checked. 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.
