## Why this matters

A site-specific alias in a breach report tells you which account needs immediate attention. Privacy is easier to defend before this information is collected than after it has spread.

## The protection

Monitoring and unique aliases work together: the alert points to a specific service rather than a generic inbox address.

## Take action

Change that service's password, review sessions, and replace the alias if necessary. Do not assume a leak is limited to email addresses. Email protection depends on the route and settings. Ordinary mail involving outside providers is not automatically end-to-end encrypted, and email metadata is not universally hidden.
