Start with the purpose
Use a temporary address only when the communication is genuinely short-lived and losing access would not create harm. A permanent address or managed alias is often better for purchases, subscriptions, and account recovery.
Minimize risk
- Never share passwords, financial details, or identity documents.
- Assume an address may expire or become blocked.
- Avoid public inbox systems for private messages.
- Use unique passwords and multi-factor authentication for permanent accounts.
Choose the right tool
Disposable inboxes, aliases, secondary accounts, and masked-email services solve different problems. Select the least risky option that still meets your privacy needs.
