New Members notifications

When a new member signs up I dont get any notifications about it or a confirmation email that they have paid. So far i have several signed up and there is nothing in my mail or spam about them signing up. 

I cant find any setting to manage that or any info in the forums. Feels like that should be an automatic feature so im wondering if its me or something isnt working. 

Appreciate any help I can get form yall. 

agreed this is a key feature thats missing the only way to monitor a membership purchase is in the commerce area..way to cumbersome!
