Your email, your way

Mozilla Thunderbird is a free, open-source email client and productivity application for managing email, calendars, contacts, and tasks across multiple accounts.

What is Mozilla Thunderbird?

Mozilla Thunderbird is a free and open-source desktop email client developed by the Thunderbird project. It allows users to manage multiple email accounts from a single application using standard protocols such as IMAP, POP, and SMTP. Thunderbird provides email organization, powerful search, filtering, address books, calendar and task management, extensions, themes, and support for encryption technologies. It is designed to give users local control over their email experience rather than requiring them to use a webmail service. Thunderbird is available for major desktop operating systems and has expanded to mobile platforms with Thunderbird for Android.
