Is it possible to determine what OS an email was sent from? I'm hoping it would be more probable if it is sent from an email client? I don't need specific details on the OS, just whether it is Mac, Linux, Windows, etc.

In general: NO, you can not tell.
But sometimes you can. Have a look at the headers and look for something like: X-Mailer: if it says something like X-Mailer: Microsoft Outlook 15.0 it is probably Windows. But these headers can be spoofed easily.

1It may be possible to tell from the
User-Agentmail header - but this can be spoofed ... without the mail headers it is impossible to tell ... – DavidPostill – 2014-11-20T14:10:16.953
