The text that email clients display is actually the body text of the email. Adding a special preview text, aka a pre-header, actually involves adding a hidden element at the start of the body, that contains the preview text. MJML provides the mj-preview tag for this purpose.
This PR adds a custom field named newsletter_preview to the demo site's ArticlePage model and renders it using MJML in the email body. I think this is something users should add themselves, it's not necessary to add support in the library.
