About
Thunderbird is a free, open-source email client available on desktop and mobile that lets users manage email, calendars, and contacts in one place. It is funded entirely by user donations and collects no personal data, sells no ads, and does not use private messages for AI training. It is highly customizable and supports unified inboxes, tagging, and a wide range of extensions.
Problem
People waste time juggling multiple browser tabs and email accounts while sacrificing privacy to ad-funded, data-harvesting email services.
For
Anyone seeking a private, customizable, and free email client for desktop or mobile
How it works
Users download the open-source app, connect their email accounts, and manage all messages, calendars, and contacts in a single unified interface with no data collection.
