 ## Advanced Features
 ### Custom HTML Layouts with Email Wrapper Hook
 The `emailWrapper` hook allows you to apply consistent HTML layouts and styling to all emails sent through the plugin. This is perfect for adding company branding, headers, footers, and responsive styling.
 #### Basic Email Wrapper
 ```typescript
 mailingPlugin({
  // ... other config
  emailWrapper: (email) => {
    const wrappedHtml = `
      <!DOCTYPE html>
      <html>
      <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>${email.subject}</title>
        <style>
          body { font-family: Arial, sans-serif; margin: 0; padding: 20px; background-color: #f4f4f4; }
          .container { max-width: 600px; margin: 0 auto; background: white; border-radius: 8px; overflow: hidden; }
          .header { background: #007bff; color: white; padding: 20px; text-align: center; }
          .content { padding: 30px; line-height: 1.6; }
          .footer { background: #f8f9fa; padding: 15px; text-align: center; color: #6c757d; font-size: 14px; }
          /* Responsive styles */
          @media only screen and (max-width: 600px) {
            .container { margin: 0 10px; }
            .content { padding: 20px; }
          }
        </style>
      </head>
      <body>
        <div class="container">
          <div class="header">
            <h1>My Company</h1>
          </div>
          <div class="content">

    }
  }
 })
 ```
 #### Advanced Email Wrapper with Dynamic Content
 ```typescript
 mailingPlugin({
  // ... other config

    // You can access email properties and customize based on content
    const isTransactional = email.subject?.includes('Receipt') || email.subject?.includes('Confirmation');

 #### Template-Specific Layouts
 You can customize layouts based on email templates:
 ```typescript
 mailingPlugin({
  emailWrapper: (email, context) => {
    // Access template information if available
    const templateSlug = context?.templateSlug;
    let layoutClass = 'default-layout';
    let headerColor = '#007bff';
    if (templateSlug === 'welcome-email') {
      layoutClass = 'welcome-layout';
      headerColor = '#28a745';
    } else if (templateSlug === 'invoice-email') {
      layoutClass = 'invoice-layout';
      headerColor = '#dc3545';
    }
    const wrappedHtml = `
      <!DOCTYPE html>
      <html>
      <head>
        <meta charset="utf-8">
        <title>${email.subject}</title>
        <style>
          .${layoutClass} { /* template-specific styles */ }
          .header { background-color: ${headerColor}; }
        </style>
      </head>
      <body>
        <div class="${layoutClass}">
          ${email.html}
        </div>
      </body>
      </html>
    `;
    return { ...email, html: wrappedHtml };
  }
 })
 ```

    if (email.requiresAudit) {

 - `email`: The full email document from the database
