<li>3 user values: public name, email, id</li>
</ul>

Adding Data to the subject and body 
This plugin allows you to add the data for current post and/or user to the email subject and body. To do so, you have to use the format: ((dataType.value | DataID)) 
 For example: 
 Hello, John Doe! would be written as: Hello, ((user.nameDisplay | PostAuthor))
<pre><code>Here are the available values:
 * post title: ((post.title | UpdatedPost))
 * post title, unfiltered: ((post.titleRaw | UpdatedPost))
 * post content: ((post.content | UpdatedPost))
 * post content, unfiltered: ((post.contentRaw | UpdatedPost))
 * post id: ((post.id | UpdatedPost))
 * post url: ((post.url | UpdatedPost))

 * user public name: ((user.nameDisplay | PostAuthor))
 * user id: ((user.id | PostAuthor))
 * user email: ((user.email | PostAuthor))
</code></pre>
