Problem Definition

Bitbucket Server has a well documented set of Notifications that are sent to their end users.

On Bitbucket Cloud, it is easy to go to your account settings and control what you are watching and even disable notifications to a user's email altogether. This is documented on Manage email notifications. Below is an example of the UI on my account:

Suggested Solution

It'd be great if we could have the same fine grained control over one single location in case a user believes to be receiving too many notifications.

Workaround

Stop watching PRs that send you messages. However, there is no way to completely stop notifications for one single user at this stage.
