# Inboxes

> Give Erdo an email address it can receive at — so an agent can sign up to a service, read the verification code, and keep going on its own.

An **inbox** is an email address Erdo owns and can receive mail at. Create one and
you get a unique address; anything sent to it (a verification code, a magic link,
a reply) is captured and readable — by you and by the agent that needs it.

The most common use: an agent needs to **sign up to a service or app** to do a
job, and that service emails a confirmation code. The agent creates an inbox,
uses the address to sign up, then reads the code and carries on — no human
relaying emails.

## How it works

<Steps>
  <Step title="Create an inbox">
    You (or an agent, on your behalf) create an inbox and get back a unique
    address like `inbox-ab12cd34@mail.erdo.ai`.
  </Step>

  <Step title="Use the address">
    Enter it wherever an email is required — a signup form, a newsletter, a
    service that sends a one-time code.
  </Step>

  <Step title="Read what arrives">
    Erdo captures mail sent to that address and surfaces the message — subject,
    sender, body, and any **verification code** or **links** it spots.
  </Step>
</Steps>

## Private by default

Every inbox is **owned by you**. Only you — and an agent acting on your behalf —
can read its mail. Addresses are unguessable, and Erdo only captures mail sent to
an address you actually created; it does not collect arbitrary mail sent to the
domain. Delete an inbox and its stored messages go with it.

## Agents and inboxes

Because inboxes are private and owned, agents can create and read their own
freely. A typical agent flow:

> "Sign me up for a free trial of that analytics tool and pull my first report."

The agent creates an inbox, signs up with the address, reads the verification
code from the inbox, completes signup, and gets to work — all in one [conversation](/concepts#conversations).

<Note>
  Inboxes are for **receiving** mail. To **send** email (a report, an alert), an
  agent uses its email-sending tools instead — see [Automations](/automations).
