Any way to send notifications to different Emails on success/failure of SqlServerAgent job?
You have to use tsql to do that.

in the job step after your main job step add 2 more job steps:



step 2--success email

EXEC msdb.dbo.sp_send_dbmail
    @profile_name = 'YOUR MAIL PROFILE',
    @recipients = 'COMPANYMAIL@COMPANY.COM',
    @body = 'Copy and Purge BAKs success !!',
    @subject = 'Copy and Purge BAKs success',
-- to send file attachments 
    @file_attachments = 'D:\logs\log.TXT',
  -- Change below if you want to include query results from a table in the email. 
  -- Note that below is not in HTML
    @query = 'select column1, column2 from table1';


step 3-- failure email

EXEC msdb.dbo.sp_send_dbmail
    @profile_name = 'YOUR MAIL PROFILE',
    @recipients = 'COMPANYMAIL@COMPANY.COM',
    @body = 'Copy and Purge BAKs failed !!',
    @subject = 'Copy and Purge BAKs failed',
-- to send file attachments 
    @file_attachments = 'D:\logs\log.TXT',
  -- Change below if you want to include query results from a table in the email. 
  -- Note that below is not in HTML
    @query = 'select column1, column2 from table1';


and then use tsql sp_send_dbmail

Note: If you want HTML email to be send out, I have a script for that to help you out.
