[Ghost](https://ghost.org) is a popular open-source publishing platform. While Ghost uses Mailgun for sending bulk newsletters, it uses a standard SMTP configuration for **transactional emails** (such as member login links, password resets, signup notifications, and staff invitations).

Configuring Ghost to route these emails through Reloop ensures that your login links and administrative emails arrive in the inbox instantly.

---

## Prerequisites

Before starting, make sure you have:
1. A verified sending domain in your [Reloop Dashboard](https://app.reloop.sh).
2. A Reloop API Key (starts with `rl_`).

---

## Step 1: Locate your Ghost Configuration File

In self-hosted Ghost environments, the configuration is stored in a JSON file in the root of your Ghost installation directory.

- Production file: `config.production.json`
- Development/Local file: `config.development.json`

---

## Step 2: Edit Mail Configuration

Open your configuration file in a text editor and locate or add the `"mail"` block. Replace the default settings with your Reloop SMTP credentials:

```json
{
  "url": "https://yourdomain.com",
  "database": { ... },
  "mail": {
    "transport": "SMTP",
    "options": {
      "host": "smtp.reloop.sh",
      "port": 587,
      "auth": {
        "user": "YOUR_RELOOP_API_KEY",
        "pass": "YOUR_RELOOP_API_KEY"
      }
    }
  }
}
```

> [!NOTE]
> Make sure to replace `YOUR_RELOOP_API_KEY` with your actual Reloop API Key. Both the `user` and `pass` values should be set to your Reloop API Key.

---

## Step 3: Restart Ghost

For the email changes to take effect, you need to restart the Ghost process:

```bash
ghost restart
```

If you are running Ghost in a Docker container, restart the container:

```bash
docker restart ghost_container_name
```

---

## Step 3: Verify the Integration

1. Go to your Ghost admin panel (`https://yourdomain.com/ghost/`).
2. Go to **Settings** → **Staff** and invite a new staff member or send a test email.
3. Check the inbox of the invited user to confirm receipt of the invitation link.
4. Verify the delivery status and headers in your **Reloop Dashboard Logs**.
