The Notifications section allows changing general and project-specific e-mail Notification Preferences, which help monitoring builds. Access this section by pressing the Profile image at the top right corner of the screen, then choosing Notifications.
Default Notification Preferences
The available e-mail notification options allows users to receive messages every time a build fails, or more specifically, when a commit a given user pushed fails build. It is also possible to turn notifications off.
Email Preferences by Organization and Project
Settings can be specified on a per-project basis, the same way as the Default Notification Preferences. It is possible to set it to notify about all Failed builds, or more specifically, only for Own failed commits. Notifications can also be silenced for specific projects, by choosing the None option.
