This plugin will allow you to change the email from address and name that WordPress uses by default.
It is pretty simple and straight-forward, no complicated functions and forms. 
On activation you should see a new menu in your “Settings” section called “Mail Change”. 
In that page you can define 2 fields:
<ol>
<li>email address</li>
<li>email from name</li>
</ol>
That’s all there is to it… have fun!
