Conditional email sending

Hello -

I want to create a conditional script to send an email if a certain form field includes specific text. The form is already made to automatically be sent to a set array of emails when the user pushes the "Submit Form by Email" button, but I want to add a script on top of that that will submit the form additionally to another email address when there is specific information included in a specific field. Is there a way that I can do this? I'd really appreciate any help. Thank you!
