# `email.sent_context`

Reads `email.sent` outside a test.

Area 16, [Built-in services](../topics/built-in-services.md); not declinable; the next step is usually the agent's.

`email.sent` is what a test sent, caught in place of sending it, so only
a test reads it; outside a test an email goes out once its action
commits, and nothing keeps it to read:


```jadpo
/// Stops early once an email has gone out.
action stop_after_sending() -> Unit {
    if (list.count(email.sent) > 0) {
        return
    }
}
```

  |                    ^^^^^^^^^^ not in a test
  reason: `email.sent` lists the emails a test sent, which `jadpo test` catches in place of sending them; outside a test an email goes out once its action commits, and nothing keeps it to read.
  next: Read `email.sent` in a test, after the action that sends the email (agent)
