By default, WordPress sends transactional emails (like password resets, user registrations, and order notifications) using PHP's built-in `mail()` function. These emails often lack authentication and end up in the spam folder.

Using **Reloop SMTP** ensures your WordPress emails are fully authenticated with SPF, DKIM, and DMARC, leading to high inbox delivery rates.

## 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 (which acts as your SMTP username and password).

---

## Step 1: Install an SMTP Plugin

To route WordPress emails through Reloop, you need to install an SMTP plugin. We recommend **WP Mail SMTP** (the most popular free option), but any standard SMTP plugin will work.

1. Log in to your WordPress Admin Dashboard.
2. Go to **Plugins** → **Add New**.
3. Search for **WP Mail SMTP**.
4. Click **Install Now** and then **Activate**.

## Step 2: Configure SMTP Settings

1. In your WordPress dashboard, navigate to **WP Mail SMTP** → **Settings**.
2. Under the **General** tab, configure the following:
   - **From Email**: Enter a verified email address from your Reloop sending domain (e.g., `info@yourdomain.com`). Check the **Force From Email** box to ensure consistency.
   - **From Name**: The sender name you want your recipients to see.
3. Scroll down to the **Mailer** section and select **Other SMTP**.

4. Enter the Reloop SMTP credentials under the **Other SMTP** settings:

| Setting | Value |
| :--- | :--- |
| **SMTP Host** | `smtp.reloop.sh` |
| **Encryption** | `TLS` (or `STARTTLS` depending on the plugin) |
| **SMTP Port** | `587` |
| **Auto TLS** | **ON** |
| **Authentication** | **ON** |
| **SMTP Username** | *Your Reloop API Key* (starts with `rl_`) |
| **SMTP Password** | *Your Reloop API Key* (starts with `rl_`) |

5. Click **Save Settings**.

## Step 3: Send a Test Email

Verify that WordPress can successfully connect and send emails through Reloop.

1. In the WP Mail SMTP menu, go to the **Tools** tab (or **Email Test**).
2. In the **Send To** field, enter your personal email address.
3. Click **Send Email**.
4. Check your inbox (and spam folder) for the test message. Once received, check your **Reloop Dashboard Logs** to see the delivery metrics and headers.

## Troubleshooting

### Email Bounced with "Domain Verification Required"
Verify that the **From Email** configured in WP Mail SMTP belongs to a domain you have added and fully verified (with valid MX, TXT, and CNAME records) in the Reloop dashboard. Reloop will block emails sent from unverified domains.

### Connection Timeout (Port 587 Blocked)
Some shared hosting providers block outgoing port `587` to prevent spam. If the connection fails or times out:
1. Try changing the port to `2525` or `25` with `TLS` / `STARTTLS` encryption enabled.
2. If those are blocked, contact your hosting provider's support team to request that they open outbound connections on port `587` for `smtp.reloop.sh`.
