WordPress No Longer Sending Email Notifications

After the auto update (which now makes me dislike this feature) WordPress has stopped doing a lot of the basic things like email notifications. Emails are not being sent out to myself (the admin) or users when a new user is made, it was a nice feature and one that I hope WP is not abandoning. Also I had some plugins that notified certain emails whenever post status’ were changed to pending (a very useful tool with multiple authors and editors) and that is no longer sending emails from the website. I am not advanced in my WP/HTML skills so please don’t come in here and tell me I need to go through and mess with a bunch of stuff, I had a working website (to my taste) yesterday, and no longer do today. I can tell by the large amount of angered people with complaints that I am not alone, and hope WP is doing something to rectify this problem.
