In general, the system requirements will be dependent on the current version of .NET used in eM Client. At this time, it is .NET 6.

Windows

• Windows 10 or higher - systems with up-to-date security from Microsoft are recommended, but with some tweaks (like manually enabling TLS 1.2 Win 7) eM Client can still be used on older systems, it is not blocked from our side, but we cannot guarantee it
• 350 MB of free space for installation.
  • You will need additional space for data, which can be stored on a different drive if needed! Since eM Client has no limit on the number of emails/data stored in its database the only limitation is the capacity of the hard drive installed in your PC. Shared folders or network drives are not recommended due to potential database conflicts.
• Minimum of 2 GB of RAM and 1.6 GHz CPU
• Recommended for memory and processor - the more GB and GHz you have, the better :)

Terminal servers

eM Client can, of course, be used in a Terminal Server environment as well. Windows Server 2012 and newer Windows server versions are supported.

Mac OS

We officially support only the last three macOS versions.
