In WordPress you can set individual templates for pages, which allows you to easily include additional functionality. Unfortunately this feature is not available for posts. Here is where this plugin comes.
After installtion you will be able to choose a template for each post the same way you do with pages.
You can find <a href="https://codex.wordpress.org/Pages#Creating_Your_Own_Page_Templates" rel="nofollow ugc">how to your own templates</a> in the Codex.

Templates for Posts

The same as page templates, but for posts.

eTemplates simplifies the creation and delivery of dynamic emails. The plugin is best used in conjunction with custom coded application style websites that send out emails populated with dynamic data to users at specific points in the application logic.
Some examples of usage could be:
<ul>
<li>Shopping carts</li>
<li>Social media sites</li>
<li>Project management systems</li>
<li>Your custom application here!</li>
</ul>
Use eTemplates to create consistently branded emails with ease!
