Email Privacy

Practices

Email privacy improvements:
├── Use email aliases for signups (SimpleLogin, AnonAddy)
│   - Real email never exposed to services
│   - Disable individual aliases when they get spam
│   - Some password managers include this feature
├── Disable remote image loading (tracking pixels)
│   - Gmail: Settings -> Images -> Ask before displaying
│   - Outlook: Settings -> View all Outlook settings -> Mail -> External images -> OFF
│   - Apple Mail: Settings -> Privacy -> Protect Mail Activity -> ON
├── Use end-to-end encrypted email for sensitive messages
│   - ProtonMail, Tutanota
│   - PGP/GPG for technical users
└── Unsubscribe audit
    - Unsubscribe from everything you do not read
    - Use unroll.me alternative (manually, as unroll.me reads emails)
