Northmail

The mail program Outlook should have become

Three panes, dense rows, keyboard shortcuts you already know, and every account as an equal: Workspace, Exchange and Gmail side by side. Free, without ads, with an assistant that runs on your own computer and never sends a word out.

Download for macOS or Windows Free, for macOS and Windows

What makes it different

AI that never leaves your computer

The assistant runs locally, with an open model you download once. Rewrite a selection in another tone or language, turn a few keywords into a draft, get reply suggestions. No mail, prompt or index ever goes to a cloud, and nothing is sent without you seeing it first.

Classic Outlook, 2026 edition

Folder tree per account, message list and reading pane, reading pane where you want it, the shortcuts you remember. Dense by default, so a whole day fits on one screen.

Every account is a peer

Binadit Workspace, on-premises Exchange and Gmail in one window, each with its own folders, calendar and contacts. No primary account, no compromise.

Move anything anywhere

Drag a folder of five thousand messages from Exchange into Workspace and it arrives complete, with dates, flags and attachments intact. The transfer resumes after a lost connection and reports what it did.

Offline first

Your mail, calendars and contacts are stored on your computer for the sync window you choose. Search, read, write and organise on the train; it syncs when you are back.

Finds your settings itself

Type your address and Northmail finds the server. Passwords go into the system keychain, updates are signed and come from binadit.work.

Profiles: work, private, or one per client

Group your accounts into profiles, each with its own icon and colour in the bar on the left. Choose a profile and Northmail shows only the mail, calendars, contacts and tasks of those accounts. One click on All brings everything back together.

  • Unread counts and notifications for incoming mail per profile, so a quiet evening stays quiet
  • Choose the profile when you add an account, and drag profiles into the order you like
  • Profiles travel along through iCloud to your other Macs and to Northmail on your iPhone
  • Calendar, contacts and tasks follow the active profile too

How it works

  1. Add an account

    Enter your email address. Workspace accounts are detected automatically; Exchange and Gmail take a minute more.

  2. Mail arrives in the background

    Headers first, then the bodies, for the window you chose. Everything stays on your computer, encrypted by your system.

  3. Switch on the assistant if you like

    After the first account Northmail asks once. Choose a model that fits your computer, wait for the download, and it works, even without internet.
