Muttator is a free add-on for the Thunderbird mail client, which makes it look and behave like the Vim text editor. It has similar key bindings and you could call it a modal mail client, as key bindings differ according to which mode you are in. For example, the same key can select the next message while the message list has focus or can scroll down an existing message when the message preview is selected. It also adds commands for accessing most Thunderbird functionality - e.g.
:contact -firstname Martin -lastname Stubenschrott firstname.lastname@example.org will add a new contact with my details.
Muttator was initially written by Martin Stubenschrott and has found many invaluable contributers who helped out fixing bugs and adding new features.

While Muttator offers already lots of cool features, we cannot and don’t want to include every feature directly in the core. Therefore you can enhance the Muttator experience by adding plugins which add new commands or mappings. Install these plugins by copying them to the ~/.muttator/plugin/ directory (or %HOME%\muttator\plugin on Windows) unless noted differently.
If you don’t care about features but just use Muttator for the sexy looks, you can also theme that by using color schemes. You can install them by copying them to the ~/.muttator/colors/ directory (%HOME%\muttator\colors on Windows) and use it with
Unexpected features - sometimes also called bugs - are listed in our issue tracker. You can also file feature requests there.
