Temporary email safety guide
Temporary email is useful, but a public disposable inbox should never be treated as a private mailbox.
Do not use it for sensitive accounts
Avoid banking, identity documents, medical data, account recovery, legal notices, or any service you cannot lose.
If you need ownership, audit logs, or long-term access, use a private mailbox you control.
Assume links can be shared
Anyone who knows the address or link may be able to view related mail while it exists.
Do not forward secrets, passwords, personal documents, or private conversations into a public temporary inbox.
Understand email tracking
9tem restricts previews and reduces common remote-content risks, but email from unknown senders can still be unsafe.
Be careful with links, attachments, and messages asking for personal information.
