Getting your address

Sign up with an address you already have, and open the link we send to it. The link works once, for 14 days. Or choose Continue with CodeNav, which also signs you in with Google or GitHub, and skip the email.

Then you choose your name on corvo.cc and a password. A name is yours for as long as you keep it. If you leave or delete it, it refuses mail for 30 days and then anyone may take it, so move your accounts elsewhere to a new address first. On Free a name has at least 6 characters; Go allows 5, Plus 4, and Pro and Max 3.

Signing in

You sign in with the address you signed up with, your account email, and your password, or with CodeNav if you signed up through it. In Settings → Security you can add a passkey, which signs you in with Face ID, Touch ID or your phone and no password, and an authenticator app as a second step.

Forgot your password? Use Reset password; the link goes to your account email.

Verification codes

When a message carries a sign-in or confirmation code, the code sits on its row with Copy, and above the message when you open it. Fifteen minutes after it arrived, the message moves to the Archive by itself, unless you starred it or the conversation carried on. A code is only recognised in mail that passed its sender's checks, so a forged message never puts one on the row.

Images and trackers

Tracking pixels, the invisible images that tell a sender you opened their mail, are removed when mail arrives and never load. Tracking tags such as utm_source are removed from links. Other images wait until you choose Load images; then they come through our server, so the sender sees neither your address nor your browser.

You can always load images from a sender you trust, or from everyone, in Settings → Privacy.

Unsubscribing

Mailing lists that support it are unsubscribed in one click from the reader: we send the request for you. Lists that need a page or an email say so, and Corvo opens the page or writes the email for you to send.

Addresses for sign-ups

A tag needs nothing set up: mail to shop.you@corvo.cc or you+shop@corvo.cc arrives in your inbox, and the message says which tag it came to. For an address that doesn't show your name, choose New disposable address in Settings → Addresses, say what it's for, and copy the address it makes, such as quiet-harbor-27@corvo.cc. Tick Only the first message for a sign-up code or a receipt, or let it expire in 7 or 30 days.

When one starts getting mail you didn't ask for, open a message to it and choose the address above the message: archive or refuse what comes next, or pause the address. A reply leaves from the address the message came to. Free includes 3 disposable addresses, and paid plans as many as you like.

Using a mail app

On any paid plan you can send from Apple Mail, Outlook, Thunderbird or any app that speaks SMTP. In Settings → Mail apps, create an app password for each device; the page shows the server, port and user name to enter. An app password can send as you but cannot change your account, and you can revoke it at any time. Reading mail in those apps arrives later, with IMAP.

Your own domain

On Plus and up you can receive and send mail at a domain you own. Add it in Settings → Domains, and the page lists the records to add where its DNS is managed: one that proves the domain is yours, the MX record that brings its mail here, three that sign the mail you send, and a recommended DMARC policy. Each name and value has its own Copy, and each record shows whether we found it, so a typo shows up as the value we found instead.

Records are checked by themselves, so you can leave the page, or at once with Check now. Once the MX record is found, mail to the domain arrives; once the signing records are found, you can send from it too. Make its addresses in Settings → Addresses, and choose a catch-all if mail to addresses you haven't made should arrive in a mailbox instead of being refused. Plus includes 1 domain, Pro 3 and Max 10.

The calendar

An invitation from Google Calendar, Outlook or any calendar that sends one by email becomes an event. Answer it from the message with Accept, Maybe or Decline, and the organiser receives your answer as they would from any calendar. When the organiser changes or cancels it, the event follows.

In Calendar you can add your own events beside them, all day or at a time, once or repeating every day, weekday, week, month or year. To see everything in Apple Calendar, Google Calendar or Outlook, choose Subscribe from another calendar, turn the link on and paste it there. The link shows titles, times, places and notes, never who is invited. Other calendars check it on their own schedule, from every few minutes to a few hours. Anyone with the link can read it, so Reset link or Turn off if it leaks: the old one stops working at once.

When new mail names a plan you have, such as a booking, an appointment or a flight, the reading that sorts it also suggests the event. A suggestion waits on your calendar, marked Suggested from mail and linked to its message, until you choose Keep or Dismiss; it is not in the link other calendars read until you keep it. Turn it off with Suggest events from mail in Settings → Privacy.

The daily brief

In Settings → Daily brief, tick Send me a brief each morning and choose the hour. Each morning a message arrives under Updates with today's events, the mail from the last week that waits for your reply, and how much came in since the last brief. A day with nothing to say gets no brief.

It is written from what Corvo already knows about your mail and calendar, without another AI call or sending anything anywhere, so it uses none of your AI allowance. Without Sort and screen new mail with AI (Settings → Privacy) it still lists the day and the counts. The link at its foot changes or stops it.

Agents

An AI agent such as Claude can read and work in your mailbox under a grant you give it in Settings → Agents. You choose what it may do (read; read and draft; or triage, which also archives, stars, marks as read and moves to the Trash), which mail it sees (all of it, or only mail from now on), how its sends are handled, and when the grant ends, from an hour to 30 days. The page shows the token once, with the command that connects the agent to our MCP server; the same token works on the HTTP API.

An app that connects from the web, such as Claude or ChatGPT, needs no token: add https://corvo.cc/v1/mcp as a connector there. It sends you to Corvo, where you sign in, choose the same limits, and choose Allow; the app then appears in Settings → Agents like any other. When the grant ends, the app asks you again.

What an agent writes is shown on blue carbon, so it never passes for yours. By default its messages wait under Approvals until you send, edit or reject them; on Pro and Max you may let it reply to the people already on a thread without asking. Everything it does is listed in the grant's activity, and Revoke stops it at once. With a grant on the whole mailbox it can also see your calendar and propose events, which wait until you keep them. Free and Go hold one grant at a time; Plus and up, as many as you like.

The iPhone app

The app is built for iPhone with the system's own controls: swipe to archive or trash, press and hold for more, pull to refresh. New mail is announced by notification. A code copied from a row leaves the clipboard after 15 minutes.

Plans and limits

Free includes 500 MB, 50 messages a day (10 a day in your first week) and 10 recipients a message. Every paid plan sends 500 messages a day to up to 50 recipients and adds mail apps; Go has 3 GB, Plus 10 GB and your own domain, Pro 20 GB and five times the AI usage of Plus, Max 50 GB and twenty times. See Pricing. Settings → Plan shows what you use.

Limits on sending exist because every account shares the reputation of the servers that deliver mail. If many of your messages bounce or are marked as spam, sending pauses until we have looked; receiving never stops for this.

Mail from us

We write to your account email, never to your Corvo address, so it reaches you even if you cannot sign in: when you sign in from a new browser or device, when your password or two-step verification changes, when a passkey or app password is added, and when your plan changes. These cannot be turned off. If one describes something you did not do, change your password straight away.

Export and closing

Export and deletion are free on every plan. Settings › Your data downloads everything as one zip: your mail as mbox files, each mailbox's calendar, your contacts and your settings. Close your account at the end of Settings. For 30 days you can sign in, download your data and reopen it; then its mail is deleted, and its addresses refuse mail for 30 days before anyone may take them.
