Hi @Shambhu Rai .
Let me double check that what you want to do is if the file is not exist, send the e-mail.
You may use script task to first check the file existence and then drag Send email task and connect to Script Task.
Here is a detail tutorial you may take a reference to.

You may also use Foreach Loop Container to check the existence and then define a variable.
