Install Mailspring silently
The unattended switch below is the one Foundry 376, LLC declares in the installer manifest, not one we guessed by trying flags.
64-bit · user scope · publisher-declared
.\MailspringSetup.exe --silentRun it from the folder holding the downloaded file, in a terminal opened as administrator when the package installs for all users. Silent means no window and no prompts, so check the exit code rather than waiting for something to appear: 0 is success and 3010 means it worked but wants a reboot.
Download Mailspring for Mac
The macOS build as Homebrew declares it, with the same treatment as the Windows side: the publisher's own URL and a hash to check it against.

Is Mailspring safe to download?
The installer comes from a recognised distribution platform rather than Foundry 376, LLC's own domain. That is normal for this kind of software and not a red flag by itself.
The installer on this page comes with the SHA-256 Foundry 376, LLC declared, so you do not have to take our word for it: hash the file you downloaded and compare.
What this does not tell you is whether the software itself is any good, or whether you want what it does once installed. A publisher can ship something you would rather not run and the download is still authentic. We answer the question we can measure and leave the other one to you.
If Windows says “Windows protected your PC” when you run it, that is SmartScreen reporting reputation, not a malware verdict — it shows up on perfectly legitimate software from small publishers and on releases that are simply new. The reverse matters more: no warning does not mean the file was checked.
How the 95/100 score is calculated · why the source matters more than the reputation
Install Mailspring with winget
Windows ships with a package manager, and this program is in it. The identifier below is the one Microsoft's repository uses, which is also where the download URL and hash on this page come from.
Install
winget install --id Foundry376.Mailspring --exactUpgrade later
winget upgrade --id Foundry376.MailspringWhy --exact: without it winget matches on name as well as identifier, and a search that returns more than one package makes it stop and ask rather than install. Pinning the identifier is what makes the command safe to put in a script.
Not installing anything, or getting an error back? The commands that actually come up covers upgrading everything at once, what --include-unknown is for, and why winget can be missing from a machine that should have it.
Old versions of Mailspring20 with hashes
The version history of Mailspring, each release with the download URL the publisher declared at the time and the SHA-256 to check it against. Useful when an update breaks something and you need to downgrade to a build that worked.
We do not host any of these files and never re-upload them, which is the difference between this and an old-version download site.
