Subscribe by email notifications

Hi,

In my multi-site I have one site that is using the subscribe by email for newsletters. They are 2 issues:

1. I'm a super admin and I don't want to get alerts when someone subscribes or unsubscribes. How do I turn these off for just my account. The other administrator does want to receive these.

2. The email sent out is from the main website info@softwiredweb.net NOT from the website owners email info@q4intel.com. Is there some place to change this?

Thank you!
