Get BC10 Mail
The Windows app is the full BC10 Mail. It installs for your user account only, needs no administrator rights, and checks for updates by itself (you decide when to install them).
BC10 Mail for Windows
Windows may warn you the first time
The installer is not code-signed yet (a certificate is on the way), so Microsoft Defender SmartScreen shows “Windows protected your PC” and names an unknown publisher. To continue:
- Select More info.
- Check the file name starts with
BC10-Mail-Setup, then select Run anyway.
Your browser may also ask you to keep the download. If you prefer, compare the checksum below before you run it.
Check it in PowerShell: Get-FileHash .\ -Algorithm SHA512

Questions
Which installer should I pick?
The main button picks the right one for your PC when your browser can tell. If you are unsure, “Both” works on any 64-bit Windows PC and installs the matching version.
How do updates work?
The app checks for a new version shortly after it starts and every few hours. It never downloads on its own: you see “Version X is available”, then choose Download and Restart to install. Your mail, settings and keys are kept.
Can I use BC10 Mail without installing anything?
Yes. Open the web app and sign in with your own mailbox (IMAP and SMTP, for example with an app password). It runs as a guest session: nothing is stored after you sign out, and features that need to keep running while you are away, such as snooze, rules and scheduled send, are only in the Windows app.
How do I uninstall?
Use Settings → Apps → Installed apps → BC10 Mail → Uninstall. Your mail stays on your mail server.
Is there a Mac, Linux or phone version?
Not yet. Windows comes first; on other devices, use the web app in your browser.
