Once you have created your email accounts via cPanel you can either acces your email via an email client installed on your Computer/Phone or by using our Webmail.
Direct your broswer to http://www.yourdomain.com/webmail (replace yourdomain.com) to check your Webmail.
If you wish to setup a local email client (Outlook, MacOS Mail, Andrios/iOS etc) please login to http://www.yourdomain.com/webmail (replace yourdomain.com) and click your email address (top left) then "Configure Mail Client"
From here you can either download a script to setup your email client or get the required IMAP and SMTP server details.
