The Thunderbird e-mail client has been around for several years and is one of the more dependable email clients available completely for free. Originally, the program was meant to replace the Outlook Express client provided by Microsoft by adding features that had been requested by users and being much more efficient in sending, receiving, and organizing e-mails.

Today, Thunderbird has a strong following that has utilized its customizability and created many different e-mail themes that can be easily applied to the client to give it a unique and sometimes more functional look.
