What is Thunderbird Email Client?

Thunderbird Email Client is an email client developed by Microsoft and available for Windows, Mac OS X, Linux, iOS and Android devices. Thunderbird was originally released in October 2006 for Microsoft Windows and later for the Mac OS X and iOS platforms.

It was renamed Thunderbird Classic in 2012. It is partly based on the Mozilla Thunderbird email client, which itself is a descendant of the Mozilla Thunderbird email client (originally developed by Netscape).

Thunderbird was first released as free software under the GNU General Public License (GPL) version 2.0 in 2007. Since then, it has been commercially available as a commercial product, either free or paid, under the commercial Open Source Starter Edition or Standard Edition license terms.

Both versions are available from no cost to users whose machines are not running Windows XP or higher or Mac OS X 10.9 (“Mavericks”).Thunderbird’s web site describes it as: “Starring a mix of features from popular desktop email clients like Gmail, Outlook and Yahoo! Mail.”
