## Why this matters

Privacy work done only after a breach cannot make already copied messages disappear. Privacy is easier to defend before this information is collected than after it has spread.

## The protection

An encrypted mailbox, account security, and site-specific aliases reduce several common paths to exposure.

## Take action

Move the next sensitive conversation first, enable two-factor authentication, and use aliases for new signups. Protection begins with the choices you make now. 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.
