 ## 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">

-## Handlebars Helpers
+## Template Syntax Reference
-The plugin includes several built-in helpers:
+Depending on your chosen template engine, you can use different syntax:
- `{{formatDate date 'short'}}` - Format dates (short, long, or default)
+### LiquidJS (Default)
- `{{formatCurrency amount 'USD'}}` - Format currency
+- Variables: `{{ user.name }}`
- `{{capitalize string}}` - Capitalize first letter
+- Logic: `{% if user.isPremium %}Premium content{% endif %}`
- `{{#ifEquals value1 value2}}...{{/ifEquals}}` - Conditional equality
+- Loops: `{% for item in items %}{{ item.name }}{% endfor %}`
 - Filters: `{{ amount | formatCurrency }}`, `{{ date | formatDate: "short" }}`
-## API Methods
+### Mustache
 - Variables: `{{ user.name }}`
 - Logic: `{{#user.isPremium}}Premium content{{/user.isPremium}}`
 - Loops: `{{#items}}{{ name }}{{/items}}`
 - No built-in filters (use variables with pre-formatted data)
-### sendEmail(payload, options)
+### Simple
 - Variables only: `{{ user.name }}`, `{{ amount }}`, `{{ date }}`
-Send an email immediately:
+### Built-in Filters (LiquidJS only)
 - `formatDate` - Format dates: `{{ createdAt | formatDate: "short" }}`
 - `formatCurrency` - Format currency: `{{ amount | formatCurrency: "USD" }}`
 - `capitalize` - Capitalize first letter: `{{ name | capitalize }}`

-### scheduleEmail(payload, options)
+## PayloadCMS Integration
-Schedule an email for later delivery:
+The plugin provides both tasks and workflows for email processing:
 ### Tasks vs Workflows
 - **Tasks**: Simple job execution, good for background processing
 - **Workflows**: More advanced with UI, status tracking, and immediate processing options
 ### Task Integration
 The plugin provides a ready-to-use PayloadCMS task for queuing template emails:
 ### 1. Add the task to your Payload config
 ```typescript
-const emailId = await scheduleEmail(payload, {
+import { buildConfig } from 'payload/config'
-  templateSlug: 'newsletter',
+import { sendTemplateEmailTask } from '@xtr-dev/payload-mailing'
-  to: ['user1@example.com', 'user2@example.com'],
+
-  scheduledAt: new Date('2024-01-15T10:00:00Z'),
+export default buildConfig({
-  variables: {
+  // ... your config
-    month: 'January',
+  jobs: {
-    highlights: ['Feature A', 'Feature B']
+    tasks: [
      sendTemplateEmailTask,
      // ... your other tasks
    ]
  }
 })
 ```
-### processEmails(payload)
+### 2. Queue emails from your code
 Manually process pending emails:
 ```typescript
-import { processEmails } from '@xtr-dev/payload-mailing'
+import type { SendTemplateEmailInput } from '@xtr-dev/payload-mailing'
-await processEmails(payload)
+
 // Queue a template email
 const result = await payload.jobs.queue({
  task: 'send-template-email',
  input: {
    templateSlug: 'welcome-email',
    to: ['user@example.com'],
    cc: ['manager@example.com'],
    variables: {
      firstName: 'John',
      activationUrl: 'https://example.com/activate/123'
    },
    priority: 1,
    // Add any custom fields from your email collection
    customField: 'value'
  } as SendTemplateEmailInput
 })
 // Queue a scheduled email
 await payload.jobs.queue({
  task: 'send-template-email',
  input: {
    templateSlug: 'reminder-email',
    to: ['user@example.com'],
    variables: { eventName: 'Product Launch' },
    scheduledAt: new Date('2024-01-15T10:00:00Z').toISOString(),
    priority: 3
  }
 })
 ```
-### retryFailedEmails(payload)
+### 3. Use in admin panel workflows
-Manually retry failed emails:
+The task can also be triggered from the Payload admin panel with a user-friendly form interface that includes:
 - Template slug selection
 - Email recipients (to, cc, bcc)
 - Template variables as JSON
 - Optional scheduling
 - Priority setting
 - Any custom fields you've added to your email collection
 ### Task Benefits
 - ✅ **Easy Integration**: Just add to your tasks array
 - ✅ **Type Safety**: Full TypeScript support with `SendTemplateEmailInput`
 - ✅ **Admin UI**: Ready-to-use form interface
 - ✅ **Flexible**: Supports all your custom email collection fields
 - ✅ **Error Handling**: Comprehensive error reporting
 - ✅ **Queue Management**: Leverage Payload's job queue system
 ### Workflow Integration
 For advanced features, use the workflow instead:
 ```typescript
-import { retryFailedEmails } from '@xtr-dev/payload-mailing'
+import { sendEmailWorkflow } from '@xtr-dev/payload-mailing'
-await retryFailedEmails(payload)
+
 export default buildConfig({
  jobs: {
    workflows: [sendEmailWorkflow]
  }
 })
 ```
 **Key advantage**: Optional `processImmediately` option to send emails instantly instead of queuing.
 ```typescript
 await payload.workflows.queue({
  workflow: 'send-email',
  input: {
    processImmediately: true, // Send immediately (default: false)
    templateSlug: 'welcome-email',
    to: ['user@example.com'],
    variables: { name: 'John' }
  }
 })
 ```

 ## API Reference
 ### `sendEmail<T>(payload, options)`
 Type-safe email sending with automatic template rendering and validation.
 ```typescript
 import { sendEmail } from '@xtr-dev/payload-mailing'
 import { Email } from './payload-types'
 const email = await sendEmail<Email>(payload, {
  template: {
    slug: 'template-slug',
    variables: { /* template variables */ }
  },
  data: {
    to: 'user@example.com',
    // Your custom fields are type-safe here!
  }
 })
 ```
 **Type Parameters:**
 - `T extends BaseEmailData` - Your generated Email type for full type safety
 **Options:**
 - `template.slug` - Template slug to render
 - `template.variables` - Variables to pass to template
 - `data` - Email data (merged with template output)
 - `collectionSlug` - Custom collection name (defaults to 'emails')
 ### `renderTemplate(payload, slug, variables)`
 Render an email template without sending.
 ```typescript
 const { html, text, subject } = await renderTemplate(
  payload,
  'welcome-email',
  { name: 'John' }
 )
 ```
 ### Helper Functions
 - `getMailing(payload)` - Get mailing context
 - `processEmails(payload)` - Manually trigger email processing
 - `retryFailedEmails(payload)` - Manually retry failed emails
 ## Migration Guide (v0.0.x → v0.1.0)
 **🚨 BREAKING CHANGES**: The API has been simplified to use Payload collections directly.
 ### Before (v0.0.x)
 ```typescript
 import { sendEmail, scheduleEmail } from '@xtr-dev/payload-mailing'
 // Old way
 const emailId = await sendEmail(payload, {
  templateSlug: 'welcome',
  to: 'user@example.com',
  variables: { name: 'John' }
 })
 const scheduledId = await scheduleEmail(payload, {
  templateSlug: 'reminder',
  to: 'user@example.com',
  scheduledAt: new Date('2024-01-15T10:00:00Z'),
  variables: { eventName: 'Launch' }
 })
 ```
 ### After (v0.1.0+)
 ```typescript
 import { renderTemplate } from '@xtr-dev/payload-mailing'
 // New way - render template first
 const { html, text, subject } = await renderTemplate(payload, 'welcome', {
  name: 'John'
 })
 // Then create email using Payload collections (full type safety!)
 const email = await payload.create({
  collection: 'emails',
  data: {
    to: ['user@example.com'],
    subject,
    html,
    text,
    // For scheduling
    scheduledAt: new Date('2024-01-15T10:00:00Z'),
    // Add any custom fields from your collection
    customField: 'value',
  }
 })
 ```
 ### Benefits of Migration
 - ✅ **Full TypeScript support** with your generated Payload types
 - ✅ **Use any custom fields** you add to your email collection
 - ✅ **Leverage Payload's features**: validation, hooks, access control
 - ✅ **One consistent API** - just use `payload.create()`
 - ✅ **No wrapper methods** - direct access to Payload's power
