Send result email

Hi,
I made a script to send backup from local disk to external FTP (with synchronize option)
It works perfectly.
But I would like to send an email to inform me in case of failure.

In documentation I found docs for sendmail.exe but this program has been abandoned..
I found blat but I hadn't found documentation to running blat with WinSCP.

Can you help me?
Thanks!

I forgot to add:

I'm already able to send mail in command line with blat.
I'm only not able to use blat in WinSCP.

I believe that the sendmail still works.

Anyway, I do not understand your question. You know how to send an email with blat command from a batch file. And you have an example how to execute a command from a batch file when WinSCP succeeds or fails:
https://winscp.net/eng/docs/script_email
So you have everything you need, don't you?

Also the documentation has now been updated to
1) Point to new maintained sendmail fork.
2) Show how to use PowerShell and its Send-MailMessage cmdlet.
