WordPress relies on email for crucial notifications like contact form submissions, password resets, and admin alerts. However, if emails from your site aren’t reaching recipients, you might face serious disruptions. This issue is usually caused by server misconfigurations, spam filters, or missing SMTP settings. Let’s look at how to fix it.


Why WordPress Emails May Not Be Sending

  1. Server Email Settings
    Some hosting servers are not configured to send emails via PHP mail().
  2. Spam Filters
    Emails may be flagged as spam due to improper headers or domain reputation issues.
  3. Missing SMTP Configuration
    Without proper SMTP (Simple Mail Transfer Protocol) settings, WordPress emails can fail to deliver.
  4. Plugin or Theme Conflicts
    Certain plugins or themes may interfere with WordPress’s email functionality.

How to Fix WordPress Email Not Sending

  1. Use an SMTP Plugin
    • Install a plugin like WP Mail SMTP to configure your site’s email settings.
    • Set up SMTP using your email provider’s credentials, such as Gmail, SendGrid, or a custom domain email.
  2. Verify Server Email Settings
    • Check if your hosting server supports PHP mail(). If not, use an SMTP service.
    • Upgrade to reliable hosting like Hostinger or Pressable for better email support.
  3. Check Spam Filters
    • Ensure your email headers are configured correctly to avoid spam filters.
    • Use tools like Mail Tester to analyze email deliverability.
  4. Test Plugins and Themes
    • Deactivate plugins and switch to a default theme to check for conflicts.
    • Reactivate them one by one to find the cause.
  5. Use a Third-Party Email Service
    • Consider using services like SendGrid, Mailgun, or Amazon SES for reliable email delivery.
    • These services provide detailed tracking and better deliverability rates.
