Unified Contact Validation Function:

// Comprehensive all-in-one contact validation
async function validateBrevoContact(contactData) {
  const validationPromises = [];
  
  // Email validation for email campaigns
  if (contactData.email) {
    validationPromises.push(
      validator.validateEmail(contactData.email, {
        include_deliverability: true,
        include_engagement_prediction: true,
        platform: 'brevo'
      })
    );
  }
  
  // SMS validation for SMS campaigns
  if (contactData.phone) {
    validationPromises.push(
      validator.validatePhone(contactData.phone, {
        include_sms_capability: true,
        include_carrier_info: true,
        platform: 'brevo'
      })
    );
  }
  
  // Execute all validations
  const [emailResult, smsResult] = await Promise.all(validationPromises);
  
  // Create unified customer profile
  const unifiedProfile = {
    contact_id: contactData.id,
    email_valid: emailResult?.is_valid || false,
    email_quality_score: emailResult?.deliverability_score || 0,
    sms_valid: smsResult?.is_valid || false,
    sms_capable: smsResult?.sms_capable || false,
    preferred_channel: determinePreferredChannel(emailResult, smsResult),
    overall_quality_score: calculateUnifiedQuality(emailResult, smsResult),
