Thunderbird email client

Mozilla Thunderbird is best described as a free, open-source, cross-platform email, news, and chat client developed by the Mozilla Foundation. The project strategy was modeled after Mozilla Firefox.

Besides the capability to house a unified inbox for multiple email accounts, Thunderbird comes with built-in Do Not Track and remote content blocking, real-time contact chat, one-click address book, and more.

This truly is a lightweight email client that won’t bog down your computer, yet those countless themes and add-ons are perfect to change its look exactly how you want.
