cPanel is among the preferred website hosting Control Panel instruments and it's used by millions of users globally. Its popularity is due to its convenience and intuitive interface, which will enable you to access a lot of features with just a few clicks. You are able to move, copy and upload files, set up new databases and add users with various stages of access, create e-mail addresses, enable spam security and SPF validation, view account usage statistics, and much more. cPanel is used by many reseller website hosting providers, because it contains a reseller-level Control Panel named WebHost Manager (WHM). The latter is a powerful instrument which will enable you to create website hosting packages and to select all of their features. You can also generate and modify client hosting accounts, access and modify a lot of server-side settings and DNS zone records, install modules and apps, and many more. cPanel and WHM can be used with many billing applications.
