Get email notifications for issues and issues on my Github repository

How can I receive email notifications when someone opens a problem on a repository I own?
I have a small open source plugin that I manage and when a user reports a problem or sends a PR, it is important for me to be notified.

I can not find a setting that allows me to set up an email for my repo.
I can configure e-mail notifications for existing problems, but that's not what I need.
