There have been requests for Mailspring to run on Windows ARM.
This is already possible, although performance has been a problem in the past. More info about Windows 10 Electron on ARM
This was suggested here:
For macOS ARM support, see: Mailspring for Apple Sillicon Macs
What about Arm for Linux? Devices like the Raspberry Pi could use a great email client
The way I see it ARM devices from MS and Apple plus ARM devices like RaspberryPi’s on linux make this support a must for such an essential app like Mailspring. Yeah the app will run emulated, but with so many people buying Apple Silicon, ARM devices will become more available and native support that will come with performance and battery improvements will become a really big deal in the coming months.
Please add arm64 Linux support!
