Can I opt out of certain notification emails?
Currently there is no setting to disable this function, but it will be an added feature in the up-and-coming user interface.
Meanwhile, the current way to work around this issue is to create an email filter that filters emails from firstname.lastname@example.org with a subject line that matches the emails you DO NOT want to see. Then set those emails to go to trash automatically. This way, you can still receive other notification emails
