SSIS – Using system variables in Send Mail Task

“Send Mail Task” is not the most flexible way to send out emails from a SSIS package. See my previous blog “SSIS – Auditing Strategy Through Package Event Handlers” to see how to use a XML Task and a Script Task to send out HTML emails.

But there are also situations where we just want to use the straightforward Send Mail Task to send out a notification if an error occurs.


Send out an email notification when error occurred in a SSIS package; Need to include the error description and the error source.


Step 1: to capture the error, create a Send Mail Task in the OnError Event Handler at the package level.


Step 2: In the Send Mail Task, try not to hard code anything, instead, use the Expression window to create expressions for the task properties.

I’ve created expressions for 4 very basic properties for the Send Mail Task, i.e. FromLine, MessageSource, Subject, ToLine.


The Subject property captures the machine name, which can tell you which environment the error is from. The MessageSource property captures the error description and the error source. Finally, the ToLine is set to a user variable which holds the email address you want to send the email to.

Because this task is in the OnError even handler, you will only receive the email if your package failed.

If you are like me, and do not write expressions in SSIS package everyday, the syntax can be tricky. Here is the syntax for the MessageSource property:

"Error Desc: " + @[System::ErrorDescription] + " Source Name: " + @[System::SourceName]
