I managed to change my login e-mail address some months ago. But still my notifications (from firstname.lastname@example.org) are sent to the old address (I initially signed up with this address at StackExchange about 4 years ago). Where can I change the e-mail address notifications are sent to?
You can change it at https://meta.stackexchange.com/users/preferences/current
This is the email address where all notifications are sent to.
