About this tool
Email Verifier Bulk Free is a static, browser-based client. Email Verifier Bulk Free validates an address syntax locally, then checks the domain MX, SPF and DMARC records over DNS-over-HTTPS.
The MX, SPF and DMARC lookups are real DNS-over-HTTPS queries, not guesses. 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.
