This mini-plugin demonstrates that developers can extend **YayMail** using the newly introduced **YayMail API** to:

* Add **custom email templates**.
* Register **custom elements** inside YayMail builder.
* Register **custom shortcodes** for use inside email designs.

Once installed, you will see a new email template, a new element and a new shortcode.
