I have read documentation on how to make your own custom email template.
I have read documentation on creating an email using the drag and drop buit-in modules.
But how you you make your own email template and then use the drag and drop built-in modules?
Eg like making the ones in the market place where they are custom templates but use the hubspot HubL to insert the modules wapped in your custom code?
Is there a special HubL tag to use?
