The preview pane in the template editor will show you an approximation of how your template will render, using the properties that you've set within the state pane as inputs.

If you need to adjust the properties that are used in the preview, or see what the template will look like for a different recipient or tenant, editing the data in the state pane will automatically cause the preview to update.

Sending test messages

You can send a test message by clicking the "Run a test" button in the top right of the template editor. From here, you can select a recipient and provide any of the data that you'd like to pass to the template.

Debugging template errors

If Knock cannot render your template, you'll see an error message in the preview pane. Most commonly, you'll see this error when you've got invalid liquid syntax in your template that's preventing the template from being rendered.

Frequently asked questions

If you're seeing the "Powered by Knock" branding appear multiple times in your email notifications, it's because you're double wrapping your email template in HTML.

Remember that an email template is wrapped by the email layout, which already includes <html> and <body> tags.
