A disposable inbox is useful when you only need to read a short-lived message. An alias usually forwards mail into an existing inbox and may be better for a relationship you want to keep. A permanent email account is the appropriate choice for long-term access and recovery. HaruMail is a receiving inbox, not a forwarding alias: messages appear here, and are not forwarded to your personal email.
Keep the same browser and its cookies to use your inbox for 24 hours. Creating a new address or clearing cookies removes access to the previous inbox. Use a permanent email account for banking, important accounts, and password recovery. Access expiry does not mean all stored copies are immediately deleted.
Make the choice before signing up
A one-time test notification can suit a temporary mailbox if the service allows it. A newsletter you intend to keep reading is better suited to an alias that forwards to a mailbox you control. Purchases, work and account recovery need an address you can keep accessing. An email alias still depends on its forwarding provider and destination account; check what happens if either is closed.
Check the recovery path
Before creating an account, ask whether a password reset or future security alert will be sent to the same address. If yes, use a durable address from the beginning. If you already used a temporary address, change the external account’s contact email while you can still sign in and complete any required confirmation. Creating a new HaruMail address does not update that external account.
