Why Am I Not Receiving Email Notifications?

I’ve set up AnsPress and it seems to be working nicely, with one exception.
I am not receiving email notofications.
I added one question (as admin) and also one answer and one comment… but I have not received any email notifications. I’ve checked all folders (spam etc) and nothing.
Also, the option is enabled in plugins and everything looks ok within…
Amy ideas why this isn’t sending notifications?
