-## Why This Approach is Better
-
-- ✅ **Full Type Safety**: Use your generated Payload types
-- ✅ **No Learning Curve**: Just use `payload.create()` like any collection
-- ✅ **Maximum Flexibility**: Add any custom fields to your email collection
-- ✅ **Payload Integration**: Leverage validation, hooks, access control
-- ✅ **Consistent API**: One way to create data in Payload

+## 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.
