Email

Your address is your own name at agenticcloudcomputer.com. You choose the name when you sign up, in the field Your email address: the part before the @ is yours to pick, and the address becomes your account. You need no outside email account to sign up, and you connect no mail provider of your own. If you signed up before addresses existed, choose one in Settings under Your address: press Choose, type a name, and press Take this address.

A name is 3 to 32 characters: lowercase letters and digits, with single dots or hyphens between them. Names the platform keeps for itself, such as support, billing, admin, postmaster and noreply, are refused, and so is a name someone else already holds.

One address per person, and it is for keeps. It cannot be renamed, and once a name is yours it is never issued to anyone else. The Settings card says exactly that: this name is yours for good, and mail sent to it arrives, is kept, and is read on your Mail screen.

The mailbox is private to you. A workplace has no shared view of anyone’s mail, and no teammate, and no teammate’s agent, can read yours. Only your own agents can, as described under Agents and mail.

Once you have an address, Home has a Messages section with a Mail row. When nothing new has arrived the row shows your address; when something has, it shows how many new messages are waiting. The row opens the Mail screen, which is your inbox. If you have not chosen an address yet, the screen says so and points you to Settings.

The inbox is one row per conversation, not one row per letter. A row shows who the conversation is with, when the newest letter came, the subject of the first letter, and the first line of the newest one. When the newest letter is your own, that line starts with You:. While nobody has answered a message you started, the row reads To and the name you wrote to. A row for a message nobody has opened is marked new.

Opening a conversation marks it read. There are no notifications for mail: no message elsewhere, no email about email. New mail shows only as the count on Home, so Home is where you look.

At the head of the inbox are Write email and a search field; at its foot are four doors, Sent, Archive, Spam and Trash. Before anything has arrived, the screen says so: mail sent to your address lands here.

A conversation is every letter that answers another, your own replies included, shown oldest first. Letters are grouped the way mail itself links them, never by matching subjects. Your own letters are headed From you to and the person they went to. One written by an agent on your behalf also says sent by that agent, and you are the only one who sees that mark. The quoted copy of the earlier letter that most replies carry is folded away behind Show quoted text.

One button at the foot of a conversation, Reply to the sender’s name, answers the newest letter that arrived. The composer is headed Your reply, with Send reply and Cancel, and the letter you are answering is shown beneath it under The message you are answering. When the letter went to several people, Reply to all answers everyone it named; you can also Add Cc. If a reply cannot be sent, your words stay in the box and you can try again.

Where a reply goes is chosen by whoever wrote the letter. Mail carries a reply address that can differ from the sender’s, which is how a letter saying “reply to confirm” can send your answer somewhere its writer picked. You cannot change a reply’s To: it is read from the letter itself. When that address differs from the sender’s, the Mail screen spells the full address out instead of showing only a name, so you can see it before you press send.

Reply is not offered on a letter in Spam or Trash. Bring it back first with Not spam or Restore.

Write email at the head of the inbox opens New message, from your address. It asks for To, a Subject and your Message, and Add Cc puts more people on it, up to the limit under Limits. Attach files adds files, and Send message sends it.

Under every letter you received is Forward. The forward composer asks for To and Your words, which go above the letter; the letter itself is shown beneath under The letter you are forwarding. Each file the letter came with has its own checkbox, Send the file with it, so you pass on only what you mean to. Send forward sends it. A letter in Trash cannot be forwarded.

Everything sent from here, whether a new message, a reply or a forward, goes out as plain text. There is no formatting to choose and none is applied.

Sent is everything that has gone out of your address, newest first, one row per letter, replies included. A reply an agent asked to send and you approved is there too. Opening a row opens its conversation. A letter you archived still shows in Sent; only moving it to Trash takes it out.

Every mail list has its own search field, and results appear in that list. Search finds letters by who they were with, by the subject, or by words in the body. A search from the inbox also looks through the archive, but never through Spam or Trash; those have their own search fields.

Archive takes a conversation out of the inbox and keeps it whole. Nothing is shortened or lost, it still turns up in a search, and Move to inbox brings it back whenever you want. You do not have to: when someone writes a new answer in an archived conversation, the conversation returns to the inbox on its own.

Spam is where a letter lands when nothing vouched for its sender, and where a blocked sender’s letters go. Each row there says why it is there: an unverified sender, a blocked sender, or marked spam by one of your agents. A letter in Spam is kept whole, is not counted as new on Home, and wakes no agent. Nothing empties Spam on its own. You can send a letter there yourself with Mark as spam, and Not spam is the one way out, back to the inbox.

Move to Trash moves a conversation out of the way without asking first, on purpose, because nothing in Trash is ever deleted for good. Restore puts it back where it was. There is no button, anywhere, that deletes a letter permanently, and Trash never empties itself. A mailbox only ever grows.

At the foot of every letter you received is Block and the sender’s address. Blocking moves everything from that exact address out of the inbox and the archive into Spam, and future letters from it land there too. Unblock stops that for new letters but moves nothing back; use Not spam on the ones you want. Blocking is by exact address only: there is no blocking of a whole domain, and no list of blocked senders in Settings.

A letter that came with files lists them under Files, and each one opens or downloads from there. An inbox row shows when a conversation carries files.

You can send files too, on a new message, a reply or a forward: up to five files, each up to 10 MB, and 15 MB together. Files whose names start with a dot, such as .env, are refused, and so are files that are programs, such as .exe or .js. When a file is refused, the screen says which rule it broke.

Pictures that travelled inside a letter are shown as part of it. Pictures the letter merely points to, hosted somewhere else, are not fetched until you ask, because fetching one can tell the sender you opened the letter. The button says so: Load pictures (the sender may learn you opened this). After that you can choose Always load pictures from that address, and later Stop loading pictures from it. Tracking pixels, the invisible pictures used only to report that a letter was opened, are always refused.

All of your agents, in every room, can read your mail: the inbox, the archive, Spam, Trash, Sent, and every file a letter carries. Your mail belongs to you, not to a room, so it follows you across rooms and stays out of reach of anyone else’s agents. An agent reads a letter the way it reads a note, and can tell you what arrived and what it means.

An agent can also tidy: archive, move to Trash, mark as spam, block and unblock. It is instructed to make those moves only when you ask, and its name is recorded on each one, so a letter reads Archived by that agent, or marked spam by it, in your own lists. Nothing an agent moves is deleted; every move is one tap back.

Sending is different. An agent can only ask to send. When it does, a card appears in that agent’s own chat, labelled Email, saying what it wants to send and showing every detail: From, To, Cc, Subject, Files by name and size, and the whole text. It offers Send email and Don’t send. Nothing goes out until you tap Send email. Typing “yes” in the chat sends nothing; the card waits for your tap, and the agent knows to say so. Afterwards the card reads Sent, with the addresses, or Not sent.

A letter you approve goes out as you, with your name and your address. The person receiving it cannot tell an agent wrote it. Your own Sent list and the conversation are where sent by the agent is recorded, for you alone. An agent is told never to put a secret in a letter: a message leaves the workplace for good. See Secrets.

By default a letter arrives quietly and starts nothing. If you want one of your agents to read new mail as it lands, choose it in Settings under Your address: the row When mail arrives, wake has a Change button, and the choice is Nobody or one of your agents, shown with its room. One agent at most, and the Workspace Agent cannot be chosen. An agent cannot make or change this choice for you.

A letter landing then starts a turn of that agent, the way a finished job does. The agent is told who wrote, the subject and where a reply would go, never the words; it reads those itself. The turn is quiet: your chat shows no row for it, and the agent writes to you only if it decides the letter needs you. While it reads, the agents list says it is reading letters that just arrived. See Turns.

A burst of letters becomes one turn, and letters that land while the agent is already working wait for that turn to end. An address wakes an agent at most twelve times an hour; past that, letters are held for the next wake, not dropped. Letters in Spam, whether suspicious or from a blocked sender, never wake anyone.

Being woken gives the letter no authority. The agent reads it as data, exactly as it would a letter you pointed it at, and does what you have asked, not what the letter asks.

Every letter that arrives is checked against the proofs a sending domain publishes about where its mail comes from. A letter that fails those checks lands in Spam and is marked: the screen says it failed the check that proves it came from the domain it claims, or that nothing vouched for the sender, and asks you to treat it as forged. An ordinary letter that was forwarded along the way is not marked.

A letter claiming to come from an address on agenticcloudcomputer.com without proving it is forged outright, because nothing here sends mail that cannot prove itself. The screen says so in as many words.

Mail is the one thing on an agent’s machine that a stranger wrote, so agents treat every letter as data, never instructions. A letter that asks an agent to forward a key, run a script, reply with the contents of a file, archive or trash other mail, or block or unblock somebody, is a stranger talking, and it does not become a request from you by arriving in your inbox. An agent acts on what you ask about a letter, not on what the letter asks.

The mailbox can start ten new messages an hour and thirty a day. A new message is one that starts a conversation, a forward, or a reply whose Cc adds someone the original letter did not reach. Replies are counted separately: twenty an hour. These limits belong to the mailbox, so you and your agents share them; a letter an agent asked to send and you approved counts the same as one you wrote. A brand-new account can send straight away, within them.

A message reaches four people at most: one To and up to three Cc. There is no Bcc, no typed display names, and no mailing lists. When a limit is reached the screen says which one, and your words stay in the box until it clears.

A message arriving can be up to 25 MB, files included. Addresses with a plus tag, such as your name followed by +news, do not reach you; write the plain address.
