An AI email client for Windows

The wave of AI mail clients grew up in a world where founders and early users sat almost exclusively on Macs. The products show it: the Mac app comes first, the rest arrives eventually, and the mailbox support is frequently cut to Gmail because that is what everyone around the makers uses. If a Windows machine sits on your desk, you therefore find plenty of apps that either do not exist for Windows at all, run only as a browser tab, or cannot connect your mailbox in the first place.

Yet the starting position on Windows is the same as everywhere: too many messages, too much marketing in between, too much time lost to sorting and replying. The need is there, only the supply is thinner. This page describes what BoxBee concretely delivers on Windows, and where the limits are.

The sentence that matters: this is not a special Windows edition with a reduced feature set. BoxBee is native on macOS, Windows, iOS and iPadOS, and the features are the same on every platform. Filing, dossiers and the daily brief look the same on the Windows machine as on the Mac next to it. If your team runs mixed devices, or you work on a Mac at home and Windows at the office, there is nothing to learn twice.

• Smart inbox: arriving mail is sorted ahead of you by kind and urgency instead of landing in one long list.
• AI drafts: replies are prepared in the language of the incoming message, in the tone you configured.
• Daily brief: a morning summary of what is still open and what needs attention.
• Autopilot: recognised mail is filed automatically, marketing goes into quarantine instead of sitting between the important messages.
• BeeCrypted: end-to-end encrypted direct messages, inside the same app.

BoxBee is a client, not a provider. It hosts no mailboxes and hands out no addresses. Instead it speaks IMAP and SMTP, the open standard virtually every mail provider understands: your domain host, a regional provider, Mailbox.org, Infomaniak, OVH or a server of your own. Your mailbox stays where it is, the address stays the same, the old messages stay put.

Setup needs an email address and a password. BoxBee finds the servers itself and verifies them with a real login before moving on. The only requirement is that your mailbox offers IMAP and SMTP; a mailbox reachable exclusively through proprietary interfaces is out. If you are unsure, testing is faster than researching: enter the address and see whether the login goes through.

The moment a mail app summarises, classifies or drafts a reply, the content of the message leaves the device and goes to a model. That is true of every AI mail client, BoxBee included. So the honest question is not whether processing happens, but where and by whom.

BoxBee uses Mistral, a model developed in France, and processes requests on servers in Europe. The vendor, TTA Technologies, is based in Luxembourg. Mail contents and passwords are not stored on BoxBee servers: the IMAP credentials stay encrypted in the Windows keystore on your device, and AI requests go to the model transiently, without being stored there.

This is not a certification and does not replace your own data protection assessment. It is a statement about the chain: European model, European servers, a vendor with a European address. For a law firm, a medical practice or a company with an active data protection officer, that chain is often exactly where the decision is made.

The search that brings many people to this page reads, in essence: is there a Superhuman for Windows? The short answer: Superhuman does offer a Windows app, but it connects to Gmail and Outlook and costs $30 a month, $25 a month billed annually. If your mailbox is on Google Workspace or Microsoft 365 and the price works for you, that is a legitimate choice. If your mailbox sits with your domain host or another provider, the conversation ends there.

For a large part of the market beyond that, the pattern holds: many AI mail clients are built Mac-first or bound to Gmail, and on Windows what remains is at best the browser. That is precisely the gap BoxBee stands in: a native Windows app that connects any IMAP mailbox. Detailed comparisons with the well-known names are on the comparison pages.

Entry is free: one mail account and 30 AI actions per month, with no payment method on file. That is enough to experience the smart inbox, the daily brief and the drafts with your own mailbox rather than judging them from screenshots.

The paid plans come with seven days to try for free. The exact amounts deliberately live only in the pricing section on the home page, so no stale figure is left behind here. For orientation, one comparison suffices: BoxBee sits clearly below the $30 a month that Superhuman asks.

Whether an AI mail client carries its weight on Windows is not settled on a landing page. Install BoxBee on the Windows machine you actually work at, connect the mailbox you actually work with, and watch for seven days how much the autopilot and the daily brief take off your hands. If nothing sticks after that, you open your mailbox with another app and everything is there. A client does not hold you.
