Separate important accounts from casual signups
Use your permanent email for accounts you need to keep. Use a disposable inbox for low-value trials, downloads, and tests.
Watch for tracking
Marketing emails often include tracking links and remote images. A disposable inbox reduces the connection between your personal identity and those campaigns.
Use stronger security for permanent accounts
For important accounts, use a password manager, unique passwords, and multi-factor authentication. Temporary email is a privacy tool, not an account recovery strategy.
