An anonymous encrypted mailbox lets someone send you a private message or file without learning your conventional email address or phone number. AliasCloak offers free generated mailboxes and optional paid custom aliases.
What is an anonymous encrypted mailbox?
It is an asynchronous receiving identity that can be shared instead of a normal email address. With AliasCloak, a mailbox can be reached through a generated identifier, a customized alias, or a public key. Message and file content is designed to be encrypted for the intended recipient’s private key.
Generated mailbox vs custom alias
| Feature | Generated mailbox | Custom alias |
|---|---|---|
| Price | $0 for core use | Optional paid upgrade |
| Name | System-generated identifier | Memorable user-selected alias, subject to availability and purchase |
| Messaging and files | Core encrypted workflow | Same core workflow with a customized receiving name |
| Best for | Testing, private one-off use, or users who do not need branding | Practices, projects, and repeat contacts that benefit from a recognizable alias |
Privacy advantages
- Do not publish a personal or staff email address.
- Create separate aliases or receiving identities for different contexts.
- Reduce linkability between unrelated conversations.
- Use a browser-based route for encrypted messages and large files.
- Limit server-side retention through deletion after delivery.
What anonymity does not guarantee
No tool can guarantee total anonymity in every context. Network information, timestamps, payment transactions for paid aliases, recipient behavior, browser configuration, downloaded files, and information typed inside a message can reveal identity. Do not promise patients, senders, or users that a communication is untraceable.
Healthcare use considerations
Reducing unnecessary identity exposure can support privacy, but a healthcare organization still needs to assess authorization, minimum-necessary use, device security, record handling, vendor status, and BAAs. An anonymous mailbox is a communication tool, not an identity-verification or patient-matching system.
Core generated mailbox use is free. Customizing the mailbox alias costs extra. The current price should be displayed before purchase in the AliasCloak workflow.
