I'm trying to preview email adminhtml template to front-end but its not working, I have tried below code.
{{block class='Magento\\Framework\\View\\Element\\Template' area='frontend' template='Magento_Sales::email/shipment/track.phtml' }}
If you want to preview your email template created from the backend of Magento 2.
Please navigate to Marketing>Email Templates
I hope this will help you.
