Email Validation for WooCommerce

Why Validate Emails for WooCommerce?

WooCommerce stores collect emails at checkout and registration. Invalid customer emails cause failed order notifications, poor support experiences, and inaccurate marketing lists. Validation at checkout prevents these issues.

Benefits

• ✓ Prevent failed order confirmations and shipping notifications
• ✓ Keep your WooCommerce customer list clean for marketing
• ✓ Reduce fraud from fake email signups
• ✓ Improve email marketing ROI from store data

How to Validate WooCommerce Emails

1. Step 1: Export customer emails from WooCommerce > Customers as CSV
2. Step 2: Validate the list to identify invalid and risky addresses
3. Step 3: Update customer records in WordPress database with validation flags
4. Step 4: Add email validation to the WooCommerce checkout and registration forms

API Integration

Integrate email validation directly into your WooCommerce workflow:

// WooCommerce - Add email validation at checkout
// functions.php or custom plugin

add_action('woocommerce_checkout_process', 'validate_checkout_email');
function validate_checkout_email() {
    $email = $_POST['billing_email'];
    
    $response = wp_remote_post('https://api.emailvalidator.com/v1/verify', [
        'headers' => [
            'Authorization' => 'Bearer ' . getenv('VALIDATOR_API_KEY'),
            'Content-Type' => 'application/json',
        ],
        'body' => json_encode(['email' => $email]),
    ]);
    
    $result = json_decode(wp_remote_retrieve_body($response), true);
    
    if (!$result['deliverable']) {
        wc_add_notice(
            'Please enter a valid email address.',
            'error'
        );
    }
}
