Jenkins offers a myriad of ways to set up notifications for build events. The simplest of all is the built-in email notification function. This article purports to delineate the steps to configure email notifications in a freestyle project.
1. Open the configuration of the project and scroll all the way to the post-build actions section.
2. Click on "ADD POST-BUILD ACTION" and choose "Email Notification". It may not be immediately visible on the list and you may have to scroll down to get to it.
3. In the newly-added segment, list the email addresses, separated by a whitespace, that should receive build notifications. Ticking the first checkbox cause email notifications to go out for every failed or unstable build and the second causes a separate email to go out to the commit author assuming his commit broke the build. Leaving both checkboxes unticked disables the notifications.
