Common Causes of WordPress Email Issues:

Incorrect SMTP Settings:

WordPress uses the Simple Mail Transfer Protocol (SMTP) to send emails. Incorrect SMTP settings are a common cause of email delivery failure. Ensure that your SMTP settings are accurate. You can find these settings in your WordPress dashboard under Settings > General.

Hosting Server Configuration:

Some hosting providers have restrictions on sending emails to prevent spam. Check with your hosting provider to see if there are any limitations on outgoing emails. They may provide you with specific SMTP settings to use.

PHP Mail Function:

WordPress uses the PHP mail function by default to send emails. However, some servers may have limitations or configurations that prevent the proper functioning of this function.

Blocked Emails:

Check if your email provider has marked WordPress emails as spam. This can happen if your site sends too many emails in a short period or if the content triggers spam filters.

Plugins Conflict:

Sometimes, conflicting plugins can disrupt email functionality. Deactivate all plugins and then activate them one by one to identify the problematic plugin.
 

Solutions:

Step 1: Check the Spam Folder

Before delving into technical solutions, it’s essential to rule out simple issues. Check your spam folder in your email account to ensure that legitimate WordPress emails aren’t being marked as spam. If you find them there, mark them as “Not Spam” to improve future deliverability.
 

Step 2: Verify WordPress Email Settings

• Log in to your WordPress dashboard.
• Go to Settings > General.
• Confirm that the “Email Address” field contains a valid email address.
• Ensure that “Membership” and “New User Default Role” settings are appropriate for your website.
• Save changes.

// Add the following code to your theme's functions.php file or use a custom plugin.

function customize_email_settings() {
    // Replace 'your_email@example.com' with your actual email address.
    update_option('admin_email', 'your_email@example.com');
    update_option('new_admin_email', 'your_email@example.com');
}
add_action('init', 'customize_email_settings');

 

Step 3: Test Server Email Functionality

WordPress relies on your hosting server to send emails. Follow these steps:

• Access your hosting account or cPanel.
• Look for email logs or an email section to identify any errors or delivery issues.
• Confirm that your server is configured to send emails.
• If issues persist, contact your hosting provider’s support for assistance.

// Create a test email function in your theme's functions.php file or a custom plugin.

function test_email_function() {
    $to = 'your_test_email@example.com';
    $subject = 'Test Email';
    $message = 'This is a test email from your WordPress site.';
    $headers = 'From: your_email@example.com';

    // Use wp_mail() to send the test email.
    $sent = wp_mail($to, $subject, $message, $headers);

    if ($sent) {
        echo 'Test email sent successfully!';
    } else {
        echo 'Failed to send the test email. Check your server configuration.';
    }
}

Execute the test_email_function() to check if your server can send emails. If successful, proceed to the next step.
 

Step 4: Implement an SMTP Plugin

SMTP plugins can enhance email deliverability by routing your WordPress emails through a dedicated mail server. Consider these steps:

• Install and activate an SMTP plugin such as “WP Mail SMTP” or “Easy WP SMTP.”
• Configure the plugin with the SMTP details provided by your email service provider.
• Test the email settings to ensure proper functionality.

 

Step 5: Investigate Plugin Conflicts

Conflicts between plugins can disrupt email functionality. Temporarily deactivate all plugins and test email delivery. If successful, reactivate plugins one by one, testing after each activation. Identify and address the conflicting plugin or consider alternatives.

// Use the following code to deactivate plugins for testing in your theme's functions.php file.

function deactivate_all_plugins_for_testing() {
    $active_plugins = get_option('active_plugins', []);
    
    foreach ($active_plugins as $plugin) {
        deactivate_plugins($plugin);
    }
}

Activate the deactivate_all_plugins_for_testing() function before testing email functionality. If the issue is resolved, reactivate each plugin one by one to identify the conflicting plugin.
 

Step 6: Assess Theme Compatibility

Some themes may interfere with email functions. Switch to a default WordPress theme like Twenty Twenty-One and test email delivery. If successful, the theme might be the issue. Contact the theme developer for support or choose a different theme.

// Switch to a default WordPress theme using the following code in your theme's functions.php file.

function switch_to_default_theme_for_testing() {
    switch_theme('twentynineteen'); // Change to the default theme of your choice
}

Activate the switch_to_default_theme_for_testing() function to test if the theme is causing the email issue. If successful, consider contacting the theme developer for assistance or choosing an alternative theme.
 

Step 7: Review Error Logs

Check your WordPress error logs for insights into the email issue. Locate error logs in your hosting account or use a plugin like “WP Error Log Monitor.” Review logs for any error messages related to email functions.

// Add the following code to enable WordPress debugging and log errors.

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

@ini_set('display_errors', 0);

// Log errors to the wp-content/debug.log file.
define('WP_CONTENT_DIR', dirname(__FILE__) . '/wp-content');
define('WP_DEBUG_LOG', WP_CONTENT_DIR . '/debug.log');

Check the debug log for any errors related to email functions. This information will help diagnose and address the root cause of the issue.
 

Step 8: Contact Hosting Support

If all else fails, reach out to your hosting provider’s support team. Provide details about the issue, steps taken, and any error messages encountered. Hosting support can investigate server-specific problems and offer solutions.
 

Additional Tips:

Use a Child Theme:

If you make changes to your theme’s functions.php file, it’s advisable to use a child theme to avoid losing modifications during theme updates.

Regularly Monitor Debug Logs:

Keep an eye on the debug.log file for any recurring errors or warnings, especially after updates or changes to your WordPress site.

Update WordPress and Plugins:

Ensure that your WordPress core and all plugins are up-to-date. Outdated software can lead to compatibility issues and impact email functionality.

Consider Transactional Email Services:

For high email deliverability, consider using transactional email services like SendGrid, Mailgun, or SMTP.com.

By combining these practical steps with code examples, you can systematically troubleshoot and fix the WordPress not sending email problem. Remember to test each solution carefully to ensure the problem is resolved, and your WordPress site can reliably send emails to users.
