When testing your Reloop integration, use these special email addresses to simulate different scenarios without sending real emails.

## First test after API key (onboarding domain)

During onboarding, after you generate an API key, use **Send email**. Reloop sends a message from the onboarding test domain:

| Field | Value |
|-------|--------|
| From | `onboarding@{ONBOARDING_TEST_DOMAIN}` (not `RELOOP_SENDER_DOMAIN`) |
| To | Your account email only |

You do **not** need a verified customer domain for this path. For production From addresses, add and verify your own domain.

## Simulated recipient addresses

| Address | Behavior |
|---------|----------|
| `delivered@reloop.sh` | Simulates a successful delivery |
| `bounced@reloop.sh` | Simulates a hard bounce |
| `complained@reloop.sh` | Simulates a spam complaint |

## Development tips

- Use the onboarding button or your own addresses for real inbox checks
- Use the simulated addresses above for automated tests that should not hit real inboxes
- Check the [Reloop dashboard](https://app.reloop.sh/emails) for send status

<Warning>
Never use real customer email addresses for automated load or bounce testing. Prefer the simulated addresses above, or a dedicated inbox you control.
</Warning>
