There is one requirement to send an email upon unsuccessful web-jobs only. There are 16 web-jobs which are deployed and running successfully on azure portal. I have suggested to modify the code for existing web-job but client does not want to modify web-jobs. He wants to add something extra which does not require to modify web-jobs anymore. I am confused, without modifying web-jobs, how can I send an email? I searched a lot on google and stack-overflow but didn't get anything.
How can I implement this?
