+
+#### X-GitLab-NotificationReason
+This header holds the reason for the notification to have been sent out, 
+where reason can be `mentioned`, `assigned`, `own_activity`, etc.
+Only one reason is sent out according to its priority:
+- `own_activity`
+- `assigned`
+- `mentioned`
+
+The reason in this header will also be shown in the footer of the notification email.  For example an email with the
+reason `assigned` will have this sentence in the footer: 
+`"You are receiving this email because you have been assigned an item on {configured GitLab hostname}"`
+
+**Note: Only reasons listed above have been implemented so far**
+Further implementation is [being discussed here](https://gitlab.com/gitlab-org/gitlab-ce/issues/42062)
