Email app: say what you need, the assistant drafts the letter and the reply

Open Email on the app desktop. Tell the app assistant who to write, what to say, and in what tone — it drafts the body. Open a message and ask it to reply in a given stance. You review before it sends.

In user language: for people who need to receive, write, and forward mail inside a workspace. Open Email, tell the app assistant who to write to, what to say, and in what tone; the assistant drafts the subject and body into the current compose draft. After you open an incoming message, you can also say “reply in this sense” or “forward this to so-and-so”; the assistant writes a reply from the original, or a forward with the original quoted. You read it, edit it, then say “send it” before it actually goes out.

The takeaway (read this first)

Email appears on the apps desktop of the selected workspace. You send and receive with your own mailbox or a mailbox shared in this workspace. Mail still lives at each post office; what is saved here is how to connect, not a second inbox.

Unlike an ordinary mail client, the app assistant drafts mail from what you ask. You do not have to write the full letter yourself before saying “send it”:

  • Write a new message: say the recipient, purpose, points, and tone; the assistant generates the subject and body, and they appear in the compose draft at once.
  • Reply to incoming mail: open that message first (or have the assistant open it), then say “decline / agree / reschedule / send the extra materials”; the assistant writes a fitting reply from the original, with recipient and subject already filled.
  • Forward: after opening a message, tap Forward, or say “forward this to so-and-so”; the subject has Fwd:, the body quotes the original, and sending includes the original attachments. You can have the assistant write a note for the recipient first.
  • Another pass: if it feels too hard, too long, or a point is missing, say one more sentence; the assistant revises the current draft and still does not send.

In one sentence: you say how it should read; the assistant drafts; it sends only after you confirm.

Who this is for, and what it solves

It fits people who already get work done in a Cadau workspace and also handle mail: customer incoming mail, after-meeting confirmation, quote replies, a shared front-desk mailbox.

Typical situations:

  • You know who to write and which points to cover, but you do not want to start from a blank first sentence;
  • The incoming message is long, and you want to catch what they asked before writing a proper reply as “agree / decline / reschedule”;
  • You need to forward the incoming message as-is to a colleague, with the original attachments;
  • The same letter needs a tone change: more formal, shorter, with the delivery date spelled out;
  • The workspace has a shared mailbox (front desk, support); members can all send and receive, while a personal mailbox is only usable by whoever added it.

For people getting work done: tell the app assistant what you want done. For people who only ask “how do I add a mailbox”: they get the steps — “help me write a letter” is not answered as “please fill the compose page yourself”.


How to open

  1. Select a workspace in the top bar
  2. AppsEmail

After it opens, talk to the app assistant on the right (or the current one). The same kind of request to the help assistant in another module uses the same operations.

With no workspace selected, the apps desktop is unavailable. The first time an admin opens it, this app’s notes sync to workspace knowledge so the assistant understands the module.


Focus: let the assistant write the body

The assistant is not only filling boxes with words you dictate. You say purpose, points, tone, and length; it writes a letter you could send. Subject and body appear together in the compose draft, and you can change any word.

Say it like this:

You sayWhat the assistant does
“Write a post-meeting confirmation to 张经理@company.com, a bit formal. Three points: demo next week, ask them to prepare the list, we send materials before Friday”Drafts subject and body, opens the compose draft, and fills the recipient
“This is too hard; make it more polite, and put the delivery date in its own paragraph”Revises only the current draft, does not send
“Add a line: attachments tomorrow, body today”Appends to the existing body, still waits for you to confirm
“Save as draft, don’t send yet”Saves a local draft; the post office does not have this letter
“Send it”Checks recipient and subject, then asks you to confirm before sending

Until you say “send it / send”, the assistant will not send the letter. While a compose draft is open, recipients, subject, and body you mention are written into this draft and shown at once.


Focus: write a fitting reply from the incoming message

Reply is not the same as a new message: the assistant must read the original first, then draft from your stance, not start an unrelated blank letter.

You can:

  1. Tell the assistant “open that RFQ from just now” or “search messages whose subject has quote”, or open it yourself in the inbox;
  2. State your stance, e.g. “reply for me: in stock, three working days lead time, price as last time, warm but professional”;
  3. The compose draft carries the original sender, a Re: subject, and the assistant’s drafted reply (the original is still quoted below for comparison);
  4. After you edit, say “send it”, or tap Reply and keep having the assistant revise.
You sayA fitting reply direction
“Decline moving to Friday, suggest next Wednesday, keep it steady”Acknowledge them first, explain this week does not work, give a usable new time
“Accept this quote, ask them to send the contract”Accept clearly, write the next step, avoid empty courtesy
“Acknowledge receipt for now; details on Friday”A short receipt that says when the formal answer will come
“One shorter paragraph; don’t repeat what the original already said”Compress; only add what they still lack

After you open a message, tapping Reply on the UI also brings a draft that quotes the original; saying “revise in this sense” to the assistant still works.


Focus: forward to someone else, with the original

Forward is not reply: the recipient is who you name, not the original sender. The subject has Fwd:; the body quotes the original’s sender, date, subject, and body; original attachments go with it (inline images used only for layout are excluded).

You can:

  1. Open that message, tap Forward, or tell the assistant “forward this to 李工@company.com”;
  2. Put what the recipient should see in front of the quoted original, or have the assistant draft it, e.g. “please look at this RFQ; we reply before Friday”;
  3. Check the forward-to address, then say “send it”.
You sayWhat the assistant does
“Forward that weekly report to Manager Wang”Opens a forward draft, fills Manager Wang’s address, subject Fwd:
“Forward to Li, and add a line asking him to check the lead time”Drafts a note in front of the original, still waits for you to confirm before sending
“Forward the one with the contract to Finance too”The forward draft includes the original attachments when sent

Usage examples

Example 1: after-meeting confirmation, from points to a letter

Sales finishes a meeting and tells the app assistant:

Write to customer Li, cc my manager. Subject: post-meeting confirmation. Body formal, no more than two paragraphs: Thursday afternoon we demo the online system; please prepare three trial users’ email addresses in advance; we send materials before Wednesday close of business.

The assistant generates subject and body into the compose draft. Sales changes “Wednesday” in the second paragraph to “Tuesday”, then says “send it”. The confirm box checks the recipients, then it goes out.

Example 2: an RFQ, reply from a stance

There is an RFQ in the inbox. Tell the assistant “open this RFQ and reply: model X in stock, three working days lead time, unit price as last quote, freight collect. Professional, don’t write too long.”

The assistant reads the original and drafts a reply: recipient is the original sender, subject has Re:, the body answers stock and lead time first, then price and freight, with the original quoted below. Purchasing glances at “freight collect” and taps Send.

Example 3: a shared front-desk mailbox, several people can reply

A workspace admin added support@company-domain as a shared mailbox. A front-desk colleague says “any unread”; the assistant reports the unread count. A support colleague opens the same mailbox, tells it on a complaint “apologize, promise a call back today, don’t admit compensation”; the assistant drafts a reply, then it sends after confirm. A personal mailbox is only usable by whoever added it; colleagues cannot see it.


What you can say to the assistant

Say what you want done, and it acts; ask “how / how do I” and it explains the steps.

You sayWhat the assistant does
“any unread” / “look at the inbox”Looks and reports accurately
“search messages whose subject has weekly report”Searches by keyword
“open that last one”Opens the body
“write to so-and-so, subject…, body along the lines of…”Drafts into the compose draft, does not send at once
“reply to this: decline the reschedule, suggest next Wednesday”Drafts a reply from the original, waits for you to confirm
“forward this to 李工@公司.com”Opens a forward draft and fills the forward-to address, waits for you to confirm
“send it” / “send”Sends after confirming recipient and subject
“help me add a 163 mailbox”Writes fields while the form is open; does not write the connection until you say save
“how do I add a QQ mailbox”Explains: enable IMAP on the webmail, fill the password field with an authorization code

Notes when adding a mailbox

For NetEase 163 / 126 and QQ Mail, enable IMAP on the webmail and fill the password field with an authorization code, not the website login password. If Gmail has two-step verification on, use an app password. For a custom post office, Receive method can be IMAP or POP: IMAP can see Sent and other folders; POP can only see the inbox.

Removing a connection does not delete mail at the post office. This release does not include Google / Microsoft account sign-in, and does not upload attachments while composing; attachments already received can be previewed or downloaded on the right of the message.
