MailStick is a portable private email environment that helps you communicate securely without leaving your mail behind.

Private email you carry with you

MailStick gives you a portable email workspace on a USB stick. Your accounts, keys, archives, and settings stay with you instead of living permanently on someone else’s computer.

Your emails stay on the stick

MailStick’s biggest strength is simple: your inbox lives on your own encrypted stick. The server is also private and controlled by you, so your email does not need to sit inside Gmail, Outlook, Proton, Yahoo, or any other third-party mailbox.

Your secure mail computer anywhere

Plug in your MailStick, start your private email environment, and use your mail without relying on Windows, macOS, or a regular Linux installation. When you shut it down, MailStick is designed to leave no personal mail traces on the host computer.

Private server-only workflow

Your emails live in a private server-only workflow. No third-party provider stores your inbox. Messages move between your MailStick environment and your own MailStick server, keeping the full email workflow under your control.

Send and receive through Tor

MailStick uses Tor and onion services to protect your connection and hide the location of your mail server. Your email workflow can stay private even on networks you do not fully trust.

Built for private communication

MailStick combines encrypted storage, Tor routing, local mail tools, and safe defaults into one focused system. It is made for people who want email that is portable, private, and under their control.

Open and verifiable

MailStick is built on open-source components such as Debian, Tor, Thunderbird, and YunoHost. Its design can be inspected and verified.
