        * `return_fields`: Request specific fields using [sparse fieldsets](https://developers.klaviyo.com/en/reference/api_overview#sparse-fieldsets).


        * `context`: This is the context your email template will be rendered with. You must pass in a `context` object as a JSON object.


        Email templates are rendered with contexts in a similar manner to Django templates. Nested template variables can be referenced via dot notation. Template variables without corresponding `context` values are treated as `FALSE` and output nothing.
