Email Security Check

Check whether an email address sits on a properly protected domain and, when configured, whether Have I Been Pwned has breach signals for it.

Privacy note: Your full email address is sent to VPN Advisor's server for this check. The domain is queried for live MX, SPF and DMARC records, and the address is sent server-to-server to Have I Been Pwned when configured, otherwise XposedOrNot. VPN Advisor does not intentionally retain the address or result; no API keys are sent to the browser.

What this email security check does

The tool validates the email format, checks the domain's MX, SPF and DMARC records via live DNS queries, flags common disposable or shared role addresses and searches known breach databases (Have I Been Pwned when configured, otherwise XposedOrNot). Results are not simulated.
