Your account has a set of features called "Advanced Tools". You can read more about them here: https://elasticemail.com/support/user-interface/settings/elastic-emails-advanced-tools/
The Advanced Tools are enabled by default on your account. A green check mark in your settings indicates that they are enabled. Should you wish to disable or re-enable Advanced Tools, visit the "Other" tab in your Account Settings. There you can manage this setting.
