how to change the emails address that sends users their login info?

I’m ready to start adding users to my WordPress and I plan to utilize the function where that information will automatically be emailed to the new user the instant I add them. But during a test I noticed that the email came from “WordPress” and the from email address was wordpress@mydomain.com. The message arrived to my test account fine but I just want to minimize confusion. Is there a way to change the name and email address used to send automated WordPress communications? I can’t find it anywhere. Thanks.
