Nixt Mail

What Nixt Mail is, what you see in its window, and how this documentation is organised.

Nixt Mail is the email client in the Nixt Office suite. It connects straight to the mail service you already use — Gmail, Outlook, iCloud, Yahoo, any IMAP and SMTP server, or a server that speaks JMAP such as Nixt Server — and gives you one window for reading, writing, filing and finding your mail.

What makes it different

  • Your mail goes directly between the app and your provider. Nixt Mail does not sit in the middle of your mail, in any edition. Your provider is the server.
  • Sign-ins stay in your device’s keychain. Passwords and sign-in tokens are stored by the operating system’s secure storage, never in an ordinary file.
  • Nothing about your messages is written to disk unless you ask. Offline mail is off until you turn it on, and when it is on it is encrypted. See Offline mail.
  • Messages cannot phone home. Pictures a sender hosts on the web are held back until you choose to load them, scripts are removed, and links whose text disagrees with where they go are pointed out. See Reading mail.
  • Nothing sends mail without you. Rules can file, flag and mark mail, but they cannot reply or forward. Every message leaves because you pressed Send, and Time to undo sending gives you a few seconds to change your mind.
  • Most actions can be undone. Archiving, moving to the trash and moving to a folder all offer Undo, and nothing in Nixt Mail deletes mail for good.
  • Everything works from the keyboard. Single-letter shortcuts, a full menu bar, and a command palette on ⌘K (Ctrl+K on Windows and Linux).

What is in the window

On a wide window, Nixt Mail shows, from left to right:

PartWhat it is for
Title barThe Nixt Mail name, the menu bar on Windows and Linux, which view and account you are in, and a light or dark switch.
Module railSwitches between Mail, Calendar and, where your copy includes them, Documents and Team. The Autopilot button sits at its foot.
SidebarThe Compose button, the search and command box, All inboxes when you have more than one account, your folders, and your account.
Message listThe mail in the folder you chose, with a search box, new-mail notices and Load more.
Reading paneThe open conversation, its attachments, a toolbar of actions, and a box to write a reply in.
AI panelAn optional assistant that docks on the right when AI is set up.

On a narrower window the same parts rearrange: folders move into a drawer, and on a phone-sized window you see one screen at a time. The window walks through every part.
