Creating XML body for alerts , basic alerts

All of those are part of out of the box

^^ 100% what donrobert5 said. These are out-of-the-box alerts, however, like any out-of-the-box alert, I encourage you to examine the trigger conditions and refine those if needed, especially if you feel the alert is firing too much. 

Also, if you have not done so already, consider taking the Platform Alerts and Reports class on the customer portal to help you understand the best practices for optimizing and building alerts so they do what you want when you want and minimize fals positives. This and other classes are available on-demand on the customer portal, and we will be delivering that class live at the end of June if you prefer a live class. 

Hope that helps!
