gitlab sends notification emails email address used during registration. can change target email address gitlab uses send email notifications to? i've tried setting/changing email address on "profile settings" it's used display; doesn't change gitlab sends notification emails to. ok seems figured out causing issue. as turns out "email" property on "profile settings" does specify gitlab sends notification emails. problem bit more elaborate. there 2 gitlab accounts had same username! both belonged me; 1 regular user , other admin. 2 users had different email addresses; usernames same. this caused kind of anomaly; though action triggered admin user notification email went email address of other user; strange indeed. i changed username of 1 of users make them unique. after that, worked well. hope in future.
