Using an email client such as Thunderbird (which is similar to Microsoft Outlook but free) is particularly useful when you have multiple email accounts to manage, maybe multiple sites, personal and work emails, or different email accounts for just the one website. Thunderbird will allow you to view all your email accounts in one place. Once configured you simply open up the Thunderbird application and view any email account you have added to it. You can then send emails from one place from each account. One login, for multiple account management. Notifications when a new email comes into ANY of your accounts. Far easier than web based mail which is only really suitable for accessing one account at a time.
