Your Methods on Extracting Site User Names + Email Addresses

As a newbie to both SharePoint Administration and PowerShell, I have introduced SharePoint to a smaller company in which I introduced its many obvious document security and navigation advantages.

REQUEST

Can someone provide more straightforward and simplified alternatives to extracting site user names and email addresses other than resorting to PowerShell?

My unsuccessful attempts at employing PowerShell are due to my current lesser programming expertise level that I am acquiring as time and projects allow.

Best regards,
