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 email is used only for this check and is not stored. MX, SPF and DMARC results come from live DNS lookups. Breach checks run server-side (Have I Been Pwned when configured, otherwise XposedOrNot); 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.
