I am using SQL server email client.
I am sending mails using
EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'Mailer_Profile',
@recipients = @Email,
@copy_recipients = @ccRecipts,
@body = @MESSAGE ,
@body_format = 'HTML',
@subject = @SUB
In the @MESSAGE we are putting some information , when the mail will be opened , it has to be downloaded from our Database end. We need to track this. i.e. when it was downloaded or which mail ID it has downloaded.
