01 — Sound familiar?

Your inbox keeps borrowing your day.

You have work you care about. But first: find the thread, copy it into a chat, paste the answer back. Again.

  • The busywork keeps coming.

    Every thread becomes another round of searching, switching tabs and moving words around.

  • Help shouldn’t mean handing over control.

    You want an extra pair of hands, with clear limits on what they can read, change and send.

  • Your day deserves better.

    The longer you spend carrying messages, the less time you have for the work behind them.

02 — Meet your mail carrier

You call the shots. We carry the mail.

You shouldn’t have to ferry your inbox into a chat window. Kiewiet connects your email to your agent, so a simple request can become a finished task. Here’s what that looks like.

YOUR DAY, BEFORE

Find. Copy. Paste. Switch. Reply.

YOUR DAY, WITH KIEWIET

Ask. Review. Get on with it.

“What came in overnight that needs me?”

  1. list_messages
  2. get_message

Three need you: Thandi’s Thursday count, the Printwise invoice, and Sipho’s logo sign-off.

“Forward the Printwise invoice to accounts.”

  1. search_messages
  2. get_attachment
  3. create_attachment_upload
  4. PUT
  5. finalize_attachment
  6. send_message

Sent with INV-2207.pdf attached. Delivered.

“Draft a reply to Sipho. I’ll read it first.”

  1. get_message
  2. save_draft

Saved in Drafts. It goes nowhere until you send it.

Connection guides include Claude, ChatGPT, Grok, Claude Code and Codex. Claude Code is the currently verified client.

03 — Your way out of the loop

A little setup. A lot less back-and-forth.

  1. Request an invite

    Send us a line. We set up your address — on goukiewiet.com or your own domain.

  2. Make it yours

    Choose your password and add an authenticator app. Your mailbox starts with two locks.

  3. Connect your agent

    Connect an MCP-compatible agent, review its requested access, then give it your first mail task.

Request an invite

Start with a conversation.
We’ll help you get your address set up.

04 — Your address. Your budget.

Your own domain, for cents.

Custom-domain email at the domain you already own. $1.99 to set it up, once. After that you pay per use — for the mail you send and receive, and the storage it takes. A typical mailbox costs about a dollar a month.

05 — You stay in control

Help with your mail. Control stays with you.

When an agent connects, Kiewiet shows you where it is calling from and what it asks to do, and you allow or deny it. It gets a key for that — not your password, not your session.

2
locks on every sign-in. Your password and a six-digit code from your authenticator app, so a stolen password alone gets nobody in. A session lasts a week.
3
scopes, and no more. Read, send, or modify: each agent holds only what it asked for and you allowed, across the mailboxes you own. Browser cookies are never agent credentials.
0
third-party scripts. No webfonts and no analytics either — in the app or on this page. Nobody signs themselves up: it is invite-only.
25MiB
per letter, for your agent too. Up to ten files, through the same signed upload your browser uses.

Incoming attachments are signature-scanned with YARA-X, and a match files the letter in Spam with the reason. It is a signature check, not a sandbox: it cannot see inside archives.

06 — For you

When you want the wheel, it’s yours.

Your agent helps. You still have a fast, uncluttered mailbox for the conversations you want to handle yourself.

Swipe to trash. Undo if you didn’t mean it.

On your phone a row has no buttons — a swipe moves it, and Undo stays for seven seconds.

Primary and Other. Nothing hidden.

Newsletters and no-reply senders sort themselves aside, each with the reason. Other is one tap away, and one tap pins a sender back on this device.

  • Delivered, then opened

    Each letter you send shows whether it was delivered, and when its images were first loaded — usually, not always, someone opening it.

  • Conversations

    Replies gather into one thread, oldest first, with the one you are reading open.

  • Drafts that save themselves

    Stop typing and the draft is kept — and your agent can pick it up too.

  • Installs like an app

    Add it to your phone’s home screen or your desktop dock. No store needed.

  • Every mailbox, one sign-in

    Switch between all the addresses you own from the account menu — and your agent can reach each of them.

  • Keyboard all the way

    j k to move, # to trash, c to write, / to search.

Before you take flight

Good questions.
Straight answers.

Your inbox matters. Here’s how goukiewiet fits your day, your domain and your agent.

What is email for AI agents?

It’s a real email mailbox with a direct connection for your AI assistant. You can read and write in the goukiewiet app, or ask a connected agent to search messages, prepare drafts and send replies through the Model Context Protocol (MCP).

Can I use my own domain?

Yes. Use an address such as you@yourdomain.com. You keep your DNS provider; we help you publish the mail records for your domain. Moving incoming mail happens when you explicitly switch its MX records. See own-domain pricing.

What can my agent access?

You sign in and approve its permissions through OAuth, without giving it your password. Permissions apply across the mailboxes your identity owns. Sending requires mail.send permission; once granted, the service does not ask you to approve every send. Ending access requires a client that supports OAuth revocation; there is no in-app disconnect control yet. See how access works.

Which AI assistants can connect?

Claude Code is the currently verified MCP client. The app also includes connection guides for Claude, ChatGPT, Grok and Codex; availability and setup depend on the client. The connection uses the remote MCP endpoint at https://goukiewiet.com/mcp.

Can I sign up today, and what does it cost?

Access is currently by invitation. The published offer is $1.99 to set up your own domain, then usage-based charges. Per-use prices are estimates, and billing is not yet built. Request an invite to discuss your mailbox. Already invited? Follow the setup guide.

Do I need to install an email app?

No. goukiewiet works in your browser on phone and desktop. You can also add it to your home screen or dock as a progressive web app (PWA), with the same inbox and no app-store download.
