Your own domain
Use @yourdomain.com and nothing about the address says Kazido. One TXT
record for DKIM, not three pointing at somebody else.
Masked email with a boundary
An email address only one company can use.
Give every service its own address. Kazido binds each one to whoever writes first, and holds mail from anyone else. When your address turns up in a breach or a list you never joined, the list is worthless — and you know exactly who leaked it.
Free for 5 aliases. No card required.

Most alias services forward anything sent to the address
That makes an alias a rename, not a boundary. Once it leaks it is as noisy as the address it was hiding. Kazido treats the first sender as the one the alias belongs to.
newsletter@stripe.com
Delivered — alias pinned to stripe.com
receipts@stripe.com
Delivered — same sender
offers@data-broker.example
Held — not the pinned sender
security@stripe.com (failed DMARC)
Held — claimed stripe.com, could not prove it
Held mail is kept where you can read it and release it. Nothing is silently discarded.
How it works
-
Make an alias
In the dashboard, or in one click on any signup form with the browser extension for Chrome, Edge and Firefox.
-
It pins itself
The first sender to use it claims it. Everyone after that is measured against them, and a sender who cannot prove the domain they claim never satisfies the pin.
-
Reply as the alias
Answer from your normal mailbox. The reply goes out as the alias, and your real address never reaches the other end.
The rest of it
Attachments up to 25 MB
Both directions, matching what the major providers accept.
Held, not bounced
Quarantined mail is readable and releasable. An alias that pinned to the wrong sender is one click to repin.
We do not read your mail
Support can see that a message arrived, who from, and what happened to it. Not what it said. There is no screen that shows the body.
