mailniño Michal Foist
Use this command to install mailniño with WinGet:
winget install --id=MichalFoist.mailnino -e An e-mail client for Windows that starts fast, searches inside messages and builds its address book on its own. Unified inbox across accounts, labels visible in other clients too, snooze and send later, calendar with invitations, S/MIME digital signatures, full mailbox backup and tracking-pixel blocking. Czech data boxes (ISDS) sit right next to regular mail — received and sent, including documents. It logs in to them only on click, because logging in legally delivers the messages. Your mail stays on your computer: mailniño has no server and no accounts, and nowhere to send your mail. Passwords are kept in the Windows Credential Manager. Available in Czech, Slovak, English, Spanish, Ukrainian and German.
