Connect 163 Mail to Muse

Updated 29 October 2026

Yes — Muse can read, search and reply to your 163 Mail through Mailopoly. Connect 163 Mail to Mailopoly with a NetEase authorization code, add Mailopoly to Muse as a custom connector, sign in and ask. One connection covers 163 Mail and every other account you own. 163 Mail requires an authorization code generated in NetEase's settings; your mailbox password won't work in mail apps.

This guide also covers NetEase Mail, 126.com, yeah.net and 188.com — the steps are the same.

Before you start

A Mailopoly account — 7-day free trial, no credit card.
163 Mail requires an authorization code generated in NetEase's settings; your mailbox password won't work in mail apps.
Access to Muse — Meta is rolling it out country by country.

Connect 163 Mail to Muse in three steps

1 Connect 163 Mail to Mailopoly

Start a Mailopoly account at mailopoly.com/sign-up — 7-day free trial, no credit card.
In 163 Mail on the web, open Settings → POP3/SMTP/IMAP and switch on the IMAP/SMTP service.
Create an authorization code and complete the security check NetEase asks for. Copy the code.
In Mailopoly choose Add email account, enter your full 163 address and paste the authorization code in the password field.

2 Add Mailopoly to Muse

This part is the same whatever you connected in step 1.

Add Mailopoly to Muse

These steps are taken from public documentation, and we haven't yet checked each one in Muse ourselves. If a label doesn't match what you see, Muse's own help page, linked below, has the current wording.

Open a chat in Muse — on the web or in the app — and ask it to create a custom connector for a remote MCP server called Mailopoly at `https://fastapi.prod.aws.mailopoly.com/mcp-server/`. Muse walks you through the rest.
Sign in with your Mailopoly account when prompted, then choose what Muse is allowed to do. Reading, making changes and sending are separate permissions.
Back in a chat, ask.

Mailopoly isn't in Muse's connector list, so Muse takes it as a custom connector — the same connection, added with one sentence instead of a tap. Muse connects from Meta's cloud, so there's nothing to install.

3 Ask about your 163 Mail

Whatever you've connected to Mailopoly is what your assistant can reach. Some things people ask on day one:

What's new in my 163 Mail Cleanbox today?
Find the delivery notice in my 163 Mail and track the parcel.
Reply to the last message from the supplier from my 163 address.

163 Mail server settings

Mailopoly fills these in for you when you enter your address. They're here in case you need to check them or your provider uses something unusual.

IMAP server	imap.163.com
Port	993
Security	SSL/TLS
Username	Your full email address
Password	NetEase authorization code

What Muse can do with 163 Mail through Mailopoly

Search 163 Mail — and every other account you own — in one question. By sender, date, topic, or the half-remembered phrase somewhere in the body.
Read your Cleanbox, not your whole inbox. Mailopoly sorts 163 Mail as it arrives: personal and important mail in Cleanbox, promotions and newsletters in Other. Ask for either.
Summarise a thread, a day or a week. "What did the school send this week?" comes back as an answer, not a list of links.
Reply from your 163 Mail address, in your voice. Save a draft to Mailopoly for review, or send — sending is a separate permission and a confirm-first action.
Schedule a send for later, and cancel it if you change your mind.
Pull out invoices, events and deliveries. Amounts and due dates, calendar invitations, parcel tracking — extracted on arrival and added to My Day.
Find an attachment. Every attachment from 163 Mail lands in PolyBox, so "find the PDF the accountant sent" just works.
Unsubscribe, snooze, file and mark read from the chat, on whichever account the mail belongs to.

Reading, making changes and sending are separate permissions you grant when you connect, and you can revoke Muse at any time from Settings → Security in the Mailopoly app. More on the security page.

What goes wrong with 163 Mail, and the fix

Your mailbox password won't work. Only the authorization code is accepted.
The code is shown once and can't be recovered, only replaced.
126.com, yeah.net and 188.com accounts use the same process on their own servers, which Mailopoly sets for you.
Muse doesn't offer to create the connector: say exactly what you want — a custom connector for a remote MCP server called Mailopoly at the address above — and that it signs in with OAuth.
Mailopoly isn't in Muse's connector list: add it as a custom connector instead. It's the same connection to your Mailopoly account.
