Is a privacy issue and some email clients block them 2. Does not work for non-publicly available gitlab instances behind firewalls 3. ~~Frankly, I consider it a security issue that an email client can display them without being logged in: gitlab-ce#51503 (and logging in in the email client would not be possible)~~ Edit: though this is still my personal opinion, this has been determined to "work as expected" by Gitlab engineers 4. Also does not work for Gitlab-specific **assets** of an instance between a firewall like e.g. icons: gitlab-ce#24859 The solution would be to embed all images into the mails directly. * This feature seems to have been implemented in gitlab-ce!373 but it is broken again. * The request has already been posted here some time ago: https://forum.gitlab.com/t/images-arent-showing-in-emails/6836
