Real mail, no gimmick
Mailboxes are operated by mail.sb —
send, receive, sign in from the apps you already use. The MX record of this very domain
points at mail.mail.sb. You just watched it answer.

😹.uz is a real, registered email domain: one laughing cat, four bytes of punycode, live mailboxes by mail.sb. Type your name on the stamp and claim it.
▲ made of particles — poke it, it knows both its names

← type your name on the stamp
DNS was frozen in 1983 — ASCII letters, digits, hyphens, nothing else.
Emoji arrived anyway. The trick is punycode: your browser quietly compresses
the cat into four safe characters and bolts on the xn-- badge. Every mail server
on earth does this translation without being asked.
flip 🤖 robot mode in the corner to read this whole page the way a mail server does. the particle cat will follow suit.
Every claim on this page can be checked from any terminal on the planet. This session was run against the live domain — replay it yourself, character for character.

mail.sb registers accounts without demanding personal information, and the domain ships
pre-wired with SPF, DKIM and DMARC, so the cat
clears customs at strict mail servers.
People forget names, companies, whole conversations. Nobody forgets the address with a crying-laughing cat in it. Your sender line does the marketing before the subject line even loads.
Internationalized domains are a real internet standard (IDNA). Modern clients render the
cat; older software falls back to the ASCII twin xn--038h.uz — same domain,
same mailbox, machine-spelled.
Yes. 😹.uz is registered, resolves, and its MX record points at
mail.mail.sb — the mail exchanger run by mail.sb. Addresses on it send and
receive like any ordinary mailbox. Section 02 above is a live replay of the lookup.
Modern browsers and mail clients render 😹.uz natively. Software that predates
emoji shows the ASCII twin xn--038h.uz instead — the same domain, machine-spelled.
That fallback is precisely why emoji domains can exist at all.
😂 has been the most-used character on the internet for a decade. 😹 is what happens when a cat hears the same joke. Cats already run the internet — giving them an email domain was the natural conclusion.
Head to mail.sb, the service that operates mailboxes on this domain, and pick your name. Registration doesn't ask who you are — only what you'd like the cat to call you.
One emoji. Four punycode characters. Zero forgettable emails.
free names at mail.sb — no personal information required at the counter.
