Hi Talend Folks,
Yes, it is, using tSendMail components, in the Internet section of component palette.
As there can be many places where a job fails, and it's usually important to know more than just that it failed, I normally attach a tSendMail via an On Component Error Trigger to any components which could possibly fail, and most can. I then build a meaningful email body with plenty of information about exactly where the job has failed, and include any variables etc. which might be relevant. By doing this I get useful feedback if any unattended jobs fail.
At the end of my job, I also have a tSendMail component connected via an On Subjob Ok Trigger to the last sub-job, which sends an email confirming that everything has completed successfully.
Just re-read my reply, and it sounds like I attach a tSendMail via On Component Error to pretty much everything, but unless I expect the actual data to be a serious problem (and I'd normally handle this properly in the job) it's usually just database, Internet and file input/output components, plus anything which runs externally like tSystem and tSSH.
