# Resend

> Send transactional email, manage contacts and segments, and react to Resend events.

Import Resend actions and triggers from `automate.ax/resend`. Resend supports
both OAuth and API-key connections; the platform selects a connection with the
access required by each action. Action inputs accept plain values or compatible
signals, while trigger options are static.

```ts theme={null}
import { automation } from "automate.ax"
import { onResendEmailBounced } from "automate.ax/resend"

export default automation("Watch Resend bounces", () => {
  const bounced = onResendEmailBounced()
  bounced.transform(({ data }) => data)
})
```

## Accounts

Leave `account` unset to use the project's default Resend binding, or pass a
named binding created with `resendAccount`. See [Integration accounts](/concepts/integration-accounts).
Trigger account selection must be static.
