Let your AI agent untangle the bills, risks and news hiding in your inbox

What you will get

Over the years you've signed up for services, linked your card to subscriptions, and maybe have a server or domain about to expire. The notices are all in your inbox, just scattered across several accounts and thousands of emails that nobody goes through. This tutorial shows you how to use Mail Agent in NetEase Mail Master to connect your Gmail, Outlook, QQ and 163 accounts, then have it do three things for you: audit your subscriptions and renewal risks, turn a pile of newsletters into a weekly brief, and organize back-and-forth partner emails into a progress table. All of it happens inside the mail app, by tapping and talking to it. No coding needed. The article includes four prompts you can copy and paste.

Here's how the work is split: it reads, sorts and drafts. Sending, deleting and paying are always up to you. In step 2 we'll write this rule into its long-term memory before it touches your inbox.

Why start with your inbox

Subscription charges, invoices, security alerts, renewal reminders and partner quotes almost always arrive by email first. Your inbox is a personal database you've been filling for years. All it lacks is an assistant that reads every message and can pull them together across accounts. That's what Mail Agent does:

• It searches across inboxes. Once you add several mailboxes to the same app, it searches all of them at once.
• You can ask it questions. Just ask in plain language. It tries different keywords, reads the emails and answers.
• It can export files and drafts. You can export organized tables, and replies are saved only as drafts.

Step 1: Install the app and add your main inboxes

On your phone or computer, install or update NetEase Mail Master, then sign in to the inboxes you use most (personal email, work email, and the Gmail you use for the services you signed up for). After updating, the AI icon in the middle of the bottom bar is the entry point for Mail Agent.

Both images are from the official NetEase Mail Master App Store page. The screenshots are in Chinese. Check first whether your company allows third-party mail apps and AI to read work email. If it doesn't, connect only your personal inbox.

Step 2: Set the rules first, then let it work

Mail Agent has long-term memory. Open the menu in the top left and go to the personalization settings, where you'll see two sections: user profile and guidelines. The guidelines use the Soul.md format, which you can think of as an employee handbook for the AI. It reads them at the start of every conversation. This step matters most, so get it right before anything else.

In your user profile, write one or two sentences about who you are and what your inbox is for. For example: "I'm an indie developer and content creator. My inbox is mostly tool subscriptions, partner emails, user feedback and industry newsletters." Then copy the guidelines below and adjust them to fit you:

Why write this first: once these rules are in long-term memory, they apply automatically every time you ask, so you don't have to repeat yourself. The "save only to drafts, don't delete emails" rule matters most, because it stops the AI from acting right away if it misreads what you want.

Step 3: Audit subscriptions, bills and renewal risks

Open Mail Agent and send it this:

Check all emails in every inbox from the last 6 months, and make a subscription and account risk audit in three tables:
1. Active charges: all memberships and software, prepaid API credits, cloud servers and domains. List the service name, the amount in its original currency, the billing cycle, and the next charge date. If a payment has both a charge notice and an invoice, count it once. Keep amounts in their original currency, and don't convert them.
2. Risks: API key or login alerts, password resets, failed payments, and servers or domains about to expire. Put the most urgent first.
3. Unclear: quotes and promotions with no actual payment don't count as bills. If an amount or date is unclear, put it in this table and attach the original email.

It will search with different keywords while it checks renewal reminders and payment receipts to verify the details. If it can't find something, it will tell you. Once it's done, say "Export these three tables to Excel" and you'll get a file. Then go through the file and cancel the subscriptions you don't use, one by one.

Why ask it to keep original currencies and skip quotes: without those instructions, it can easily count the same payment twice or treat a promo email as a bill. The table looks clean, but the numbers are wrong.

Step 4: Turn a pile of newsletters into a weekly brief

A lot of firsthand information lives in email: industry newsletters, GitHub activity and keyword monitoring alerts. When you subscribe to too many, it's hard to keep up. Now you can subscribe freely and have Mail Agent summarize them once a week:

Turn the industry newsletters, GitHub activity and keyword alert emails that arrived in the last 7 days into a plain-English brief. Remove ads and promotions, then cover:
1. New tools, open-source projects or approaches that keep coming up this week. For each one, explain in plain language who it helps and what work it saves.
2. User complaints, controversies, or examples of people making money.
3. The 3 directions most worth looking into or turning into content. For each one, attach the original email so I can click back to it.

If you have ongoing partner or inquiry threads that span many emails, you can also have it stitch the progress together:

Go through the emails from the last 30 days about partnerships and projects. Group emails by partner, and list: terms already agreed on, who the deal is currently waiting on, and anything due in the next 7 days. Then list any meetings and delivery dates mentioned in the emails separately. For anything that needs a reply, draft it and save it to drafts. Don't send anything.

Every Monday, open Mail Agent and ask it what's urgent this week and what's worth reading. It follows the rules from step 2, so P0 items come first.

Notes

• Letting an AI read all of your email means handing over your privacy. Only connect the inboxes you're comfortable sharing, and check your company's rules first for work email.
• Check the amounts in the tables against your bank statements. It will mark unclear items [TO CONFIRM] as the rules require, but still verify everything yourself before you cancel or change a plan.
• Saving drafts only is the bottom line. Even when it writes a good reply, read it yourself before you send it.
• The app's interface is mostly in Chinese, and Gmail and Outlook work fine in it.
