Disposable Email and File Privacy: Avoid Exposing Download Links
A download link can expose a file even when your main email stays private. Protect the link and recipient access separately from the mailbox.
A link can be the key to a file
Some file links allow anyone who has them to view or download content. If such a link reaches a guest inbox or is forwarded, hiding your primary email does not protect the document itself.
Separate two privacy decisions
Which email address is visible?
A disposable address can avoid revealing your main mailbox to the sender. It does not verify who is reading the receiving inbox or control what they do with the message.
Who is allowed to open the file?
Use the sharing service's recipient permissions. Check whether access is restricted to named accounts or available to anyone with the link. These settings matter more than the address used for a notification.
Before sharing a sensitive document
- Remove information the recipient does not need.
- Use a service appropriate for the document's sensitivity.
- Restrict access and verify the intended recipient.
- Keep access notifications on an email account you control.
- Review and revoke access when the work ends.
Where a disposable mailbox is reasonable
A non-sensitive sample file or public resource may not require lasting identity. Even then, verify the sender and avoid unexpected downloads. Temporary email does not turn an attachment into a trusted file.
Do not promise anonymous transfer
File services, network providers, and recipients may retain information about a transfer. Temporarly is a receiving mailbox, not a claim of anonymous or encrypted file delivery. Choose your sharing method based on the information involved.
