Customizing the email's from name and address

I am customizing the emails sent after a new user registers. I entered the email I would like, the name, chose plain text, the subject line, and the message. After testing it, the email message and the subject line is great, but the from name and email aren’t as I entered it into the settings. The email that it comes from is generated from our WordPress Bluehost instead. Is there another spot I need to enter the email address that I would like these new user emails to look like it’s coming from?
