Email and webmail

There are two main types of email, client-based email and webmail. Client-based email is often used by business users and involves the email being downloaded from a server to an application (such as Microsoft Outlook or Mozilla Thunderbird) on the user’s computer. Webmail is accessed through a web browser and can be accessed from any computer with an Internet connection.
