Let's use a scenario where we want to send HTML email each time a new node article is added.

To be able to embed code snippet using your favorite WYSIWYG editor in Drupal 8, you will need to do the following.

By Default, each time you created a new node, you will be shown a message saying something like "node {title} has been created".
