Now you can send emails via command line! It doesn’t have to be installed though you could do so if you please. I give you Blat!

Here is a simple example from the documentation:

@echo off
:::::::::::::: Lets set some variables ::::::::::::::
set eMail=tim@blat.tld
set subj=-s “Test Blat”
set server=-server localhost
set x=-x “X-Header-Test: Can Blat do it? Yes it Can!”
set debug=-debug -log blat.log -timestamp
::::::::::::::::: Now we run Blat! :::::::::::::::::
blat %0 -to %eMail% -f %eMail% %subj% %server% %debug% %x%
