What is a private email alias?
A private email alias is a unique address that forwards messages to your real inbox. Instead of sharing your primary address with every website, you use an alias for a specific store, newsletter, account, or form.
The key benefit is separation. If one service leaks, sells, or misuses that address, the exposure is limited to the alias you used there instead of your real email identity.
How private email aliases work
Private aliases sit between the sender and your real inbox. Mail sent to the alias is routed to you, but the sender does not need to know your primary address. You keep the convenience of one inbox while using different addresses across the web.
This makes aliases useful for everyday accounts, newsletters, receipts, trials, and any place where you want mail to reach you without exposing the address you depend on.
When to use a private alias
Use a private alias whenever a site asks for an email address and you do not want that site tied directly to your primary inbox. Common uses include shopping, social media, software tools, event registrations, community sites, and mailing lists.
A durable alias is especially useful for accounts you may need later, because you can keep receiving legitimate mail while still retaining control over the address.
Why aliases help with spam and breaches
When every service gets a different alias, unwanted mail becomes easier to trace. If one alias starts receiving spam, you know which address was exposed and can pause or retire it without changing your primary inbox.

How CleanMail handles aliases during private beta
CleanMail is currently invite-only. The goal is to make private email aliases simple enough for everyday use: create an alias, route it to your inbox, and keep control over whether that alias stays active.
