How to label GitLab notification in Gmail by headers?
📨 How GitLab sends notifications? GitLab allows you to stay informed about what’s happening in your projects sending you the notifications via email. With enabled notifications, you can receive updates about activity in issues, merge requests or build results. All of those emails are sent from a single address which without a doubt makes it harder to do successful filtering and labeling. However GitLab adds custom headers to every sent notification to allow you to better manage received notification and for example, you could add a label to all emails with pipelines results to mark them as important.
