Email to users cancelled in progress, can I see who received it?

I started sending an email to all users today and then noticed I forgot to include a subject. I didn't see anyway to stop sending, so I closed the browser window instead.

I did get an email myself, so I know some messages where sent, but I was trying to figure out if there is anyway to see how many emails were sent and who received them. I don't want to send too many duplicate emails if I can avoid it.

I've searched the manual and these forums, but haven't found anything yet.

Thanks very much.

If it's anywhere it's Admin CP -> Statistics & Logs -> Control Panel Log, but I'm really not sure if it's something that is logged, especially on 3.6.
