WordPress Integration

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.
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:

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.dev.
