FTPCaller and Emailer question

I am using FTPCaller. If I add the Emailer to the rejected port will it send me an email if the output gets kicked to the rejected port? I would have the Emailer already configured to send me an email. 

I want to double check with the Community since my workbench will stop running if the FTPCaller output is rejected. 

Here is a screenshot of a mock up workspace (note I have not set up the transformer parameters yet hence you see the red gear icons.)

Not shown below, I know it will send me an email if the FTPCaller output is sent to Output.
