Clova.Email：只接受单一发件人的邮箱服务上线
Show HN: I wrote an email app that accepts only one sender per inbox
Clova.Email 推出只接受单一发件人的邮箱服务，单个地址在被首个发件人认领后其他来源的邮件会被直接退回。系统提供单一发件人、临时和前缀三种收件箱类型，并通过 MCP 让 Claude、Cursor 等 AI 助手完成建地址、取验证码、查收据等操作。
原文给出唯一发件人收件箱规则与 MCP 接入 AI 助手的实现方式，读者可以评估它与普通邮箱服务的差异。
Inbox types Pricing MCP Data Explainer
Zero Spam. Quiet by Design.
Infinite inboxes, so nobody ever gets your real address. Give every company its own — when one leaks, you delete it, not your life.
No card required
Three kinds of inbox
Pick one based on who you're handing the address to.
01 · One-sender
One sender, one address
The first person or company to write claims the address for good. Everyone else is rejected at the door — so a resold or breached list is worth nothing.
Chase Bank ✓ claimed it
Spamco ✕ bounced
List reseller ✕ bounced
chase@yourname.clova.email
created 24 h ✕ after
3 mails in then bounced · self-wipes
02 · Temporary
Gone when you're done
Set a lifetime — an hour for a download link, a month for a trial. When it's up the inbox turns mail away, and can wipe what it holds.
03 · Prefix
Invent one at the counter
Claim a prefix of five characters or more, then anything you add after it already works — no setup, and no dash needed. Each address still locks to its first sender.

MCP
Bring your AI assistant
Connect Claude, Cursor or any assistant that speaks MCP, and hand it the inbox chores: a fresh address for a sign-up, the code that just arrived, every receipt from March. It gets only the permissions you give it.

Signing in, and your data
Sign in with a Google account, a passkey, or a username and a password. With Google, Clova.Email receives only your email address, your name and your profile photo: the address is how we know it is you, and the name and photo fill in your profile, where you can change or remove them. We never use any of it for advertising, never sell it and never share it. The whole of it is in our privacy policy.
