Change from name and email coming from site email notifications

Hello,

Can you help me with changing the from name and email address that the site email notifications come from?

I have tried adding in code suggested in this post (https://premium.wpmudev.org/blog/wordpress-email-settings/) as well as changing php.ini code recommended here (https://my.bluehost.com/cgi/help/206). Neither of these worked.

Currently, emails are coming from housepz2@box748.bluehost.com, but need to come from cindy@houseofcindy.com.

Thanks!
