Conduit, on every device.
Download the desktop app for macOS or Windows, or use Conduit in your browser with nothing to install. Native mobile apps are on the way, and this is where they'll land the day they ship.
Universal build for Apple Silicon and Intel Macs. Requires macOS 13.3 or later. Signed and notarized by Apple, with automatic updates built in.
Opens the latest release on GitHub. Download the file ending in universal.dmg.
64-bit installer for Windows 10 and 11, with automatic updates built in. It isn’t code-signed yet, so the first time you run it Windows shows a “Windows protected your PC” warning. Click “More info,” then “Run anyway.”
Opens the latest release on GitHub. Download the file ending in x64-setup.exe.
Native mobile apps are in early development. Until they land, Conduit installs from your phone's browser as an app — see below.
Desktop downloads come from Conduit’s official release page, github.com/ConduitMail/releases. Rather not install anything? The web app below is the same product.
No install required
Conduit runs as a web app right in your browser: any modern browser, always up to date, the same product the desktop apps wrap. It launches instantly. Install it for a dedicated window and an app icon:
Chrome / Edge (desktop)
Open in.conduitmail.app, then click the install icon in the address bar (or the browser menu → "Install Conduit Mail").
Safari (macOS 14+)
Open the page, then choose File → Add to Dock.
iPhone / iPad
In Safari, tap Share, then "Add to Home Screen."
Android
In Chrome, open the menu and tap "Install app."
Questions people actually ask
When are the mobile apps coming?
The macOS and Windows apps are available now, at the top of this page. Native iOS and Android apps are in early development. The web app already has everything.
Why does Windows show a SmartScreen warning?
The Windows app isn’t code-signed yet. The first time you run the installer, Microsoft Defender SmartScreen shows a blue “Windows protected your PC” screen saying it stopped an unrecognized app, with the publisher listed as “Unknown publisher.” That’s expected for an unsigned app, not a sign anything is wrong. Click “More info,” then “Run anyway.” Your browser may also ask you to confirm you want to keep the download. The macOS app is signed and notarized by Apple, so it doesn’t show this. Only download Conduit from this page or github.com/ConduitMail/releases.
Is the app the same as the web app?
Yes — same product, just wrapped in a native window with tray and notification support.
How do updates work?
The desktop app updates itself automatically. The web app and installed PWA are always current — there is nothing to install.
Do I need to install anything to start?
No. Get early access and open Conduit in your browser — install it as an app later if you want a dedicated window.
