Troubleshooting WordPress Email Delivery Issues

WordPress email delivery issues can be frustrating, especially when important notifications, such as user registration confirmations or password reset emails, fail to reach their recipients. If you’re experiencing email delivery problems on your WordPress site, there are several steps you can take to troubleshoot and resolve the issue. In this guide, we’ll walk you through the potential causes of email delivery problems and the solutions to address them:

1. Check Your WordPress Email Settings:

  • First, make sure you have access to your backup files. This typically includes:
    Verify that the email address specified as the “From” address in your WordPress settings is using your domain (e.g., Using generic email addresses (e.g., Gmail, Yahoo) can lead to deliverability issues.

2. Test WordPress Email Functionality:

  • Use a plugin like WP Mail SMTP to test whether your WordPress site can send emails successfully.
  • The plugin will allow you to run a test email to see if it’s sent and received properly.

3. Check Email Deliverability:

  • If the test email does not arrive, check your spam or junk folder in case the email was misclassified.
  • If the email still doesn’t arrive, move on to the next steps.

4. Configure SMTP for WordPress:

  • By default, WordPress uses the PHP mail() function to send emails. This method can be unreliable, leading to deliverability issues.
  • Instead, configure your site to use SMTP (Simple Mail Transfer Protocol) for sending emails. SMTP provides more reliable email delivery.
  • Use a plugin like WP Mail SMTP to set up SMTP settings for your email service provider (e.g., Gmail, SendGrid, Mailgun).

5. Check Your Hosting Provider’s Email Configuration:

  • Your hosting provider’s server settings might be affecting email deliverability.
  • Check if your hosting provider has specific email sending requirements or limitations, and adjust your WordPress SMTP settings accordingly.

6. Examine SPF, DKIM, and DMARC Records:

  • Properly set up SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) records for your domain. These records help prevent your emails from being flagged as spam and improve deliverability.
  • Consult your email provider’s documentation for instructions on setting up these records.

7. Check Plugins and Themes:

  • Sometimes, a plugin or theme can interfere with email delivery.
  • Temporarily disable plugins and switch to a default WordPress theme to see if the issue persists. If it resolves the issue, reactivate each plugin one by one to identify the source of the conflict.

8. Monitor Email Logs:

  • Email logging plugins, such as WP Mail Logging, can help you track the emails sent from your site.
  • Logs provide information on whether emails were sent successfully and can help you identify patterns or potential issues.


By following these steps, you should be able to identify and resolve common email delivery issues on your WordPress site. Remember that email deliverability can be impacted by various factors, so it may take some experimentation to find the right configuration for your specific setup. If you continue to experience problems, consider reaching out to your hosting provider or email service provider for further assistance. Contact us to get more information about it.
