# Preview & Testing Templates

Before sending templates to production users, test them with live preview data directly in the dashboard.

***

## Live Preview Data Panel

In the template editor, open the **Preview Data** tab in the right-hand inspector:

```json theme={null}
{
  "first_name": "Jordan",
  "plan_name": "Enterprise Cloud",
  "renewal_date": "October 1, 2026",
  "order": {
    "shipping_address": {
      "city": "Austin",
      "country": "United States"
    }
  }
}
```

The canvas instantly updates to display the template filled with your preview JSON variables.

***

## Sending a Live Test Email

1. Click the **Send Test** button in the editor header.
2. Enter your email address.
3. Choose whether to use the current preview JSON variables.
4. Click **Send Test**. Inspect the received email in Gmail, Apple Mail, or Outlook to verify formatting and mobile responsiveness.
