Order notifications?

Been sometime since I set up my Opencart 2.0 shop. Always get order notifications delivered to my email address.

Lately had an issue with the contact form not sending me anything but still getting order notifications.

Under Settings- Edit Settings - Mail, there is nothing filled in. Should it be required for this. If so, how am I still getting order notifications to my email address?

Confused.

Thanks!

It's hard to tell anything particular. You contact form may simply be broken.

Ok, but where are the details for my email address kept in Opencart to send order notifications to? Confused by that.

Your details doesn't mean everything related to email will work out of the box. Again, you CONTACT FORM may be broken.

Sorry, I don't get it. How can Opencart know where to send order notifications too without the email address?
