WordPress, the world’s most popular content management system, excels at creating dynamic and engaging websites. However, occasionally, users encounter issues, such as WordPress not sending emails. This frustrating problem can hinder communication, notification, and overall website functionality.

In this comprehensive guide, we’ll delve into the intricacies of WordPress email delivery, exploring the common causes of email delivery failures and providing step-by-step troubleshooting solutions to restore your website’s emailing capabilities.

Understanding WordPress Email Functionality

WordPress utilizes the wp_mail() function to send emails. This function can be used to send various types of emails, including contact form notifications, password reset emails, and administrative alerts.

By default, WordPress attempts to send emails using the PHP mail() function, which relies on the server’s mail configuration. However, this method can be unreliable due to server-side limitations or security restrictions.

To overcome these limitations, WordPress offers alternative methods for sending emails, such as using a dedicated SMTP (Simple Mail Transfer Protocol) server or a third-party email service.

Causes of WordPress Not Sending Emails

Several factors can contribute to WordPress not sending emails:

  • Incorrect Email Settings: Improperly configured email settings in WordPress can prevent emails from being sent.
  • Server-Side Issues: Server-related problems, such as mail server configuration errors or security restrictions, can block outgoing emails.
  • Plugin Conflicts: Incompatible or buggy plugins can interfere with WordPress’s ability to send emails.
  • Theme Conflicts: A poorly coded or outdated theme can disrupt the email sending process.
  • SMTP Misconfiguration: If you’re using an SMTP server, incorrect SMTP settings can prevent emails from being sent successfully.
  • Email Blacklist: Your website’s IP address might be blacklisted by email service providers, causing emails to be flagged as spam.

Troubleshooting and Resolving WordPress Email Delivery Issues

Before diving into technical solutions, it’s crucial to rule out simple causes. Check your inbox for sent emails, ensure your email address is correct in WordPress settings, and ask recipients to check their spam folders.

If these basic checks fail, follow these troubleshooting steps:

1. Verify Email Settings in WordPress:

  • Access your WordPress dashboard and navigate to Settings > General.
  • Check the “Email Address” field to ensure it’s correct and matches your email address.
  • Review the “Site Title” and “Admin Email” fields to ensure they are accurate.

2. Check Server-Side Email Configuration:

  • Contact your hosting provider to verify your server’s mail configuration and ensure it’s properly set up to send emails.
  • Check for any server-side restrictions or limitations that might be blocking outgoing emails.

3. Disable Plugins Temporarily:

  • Deactivate all plugins to identify if a plugin is interfering with email delivery.
  • Reactivate plugins one by one to pinpoint the problematic plugin.

4. Switch to a Default Theme:

  • Temporarily switch to a default WordPress theme like Twenty Twenty-Two to see if the current theme is causing the issue.
  • If the issue persists, switch back to your original theme to confirm its involvement.

5. Configure SMTP Settings:

  • If you’re using an SMTP server, ensure the SMTP settings in your WordPress configuration are correct.
  • Use a plugin like WP Mail SMTP to simplify SMTP configuration and troubleshooting.

6. Check Email Blacklist Status:

  • Use online tools like MXToolbox or Blacklist Check to see if your website’s IP address is blacklisted by email providers.
  • If your IP address is blacklisted, contact the email providers to request removal.

7. Seek Expert Assistance:

  • If none of the above steps resolve the issue, consider seeking assistance from a WordPress developer or your hosting provider.

Preventive Measures:

To minimize the risk of future email delivery issues:

  • Regularly update WordPress core, plugins, and themes to ensure compatibility and bug fixes.
  • Use a reputable SMTP server or email service for reliable email delivery.
  • Monitor your website’s email sending performance and address any issues promptly.
  • Implement email authentication protocols like SPF, DKIM, and DMARC to improve email deliverability and reduce spam filtering.


WordPress email delivery issues can be frustrating, but with careful troubleshooting and preventive measures, you can restore your website’s ability to send emails effectively. By following the steps outlined in this comprehensive guide, you can identify the root cause of the problem and implement the appropriate solution to get your emails flowing again.
