i do a large amount of web forms for a vehicle replacement company.

would it be possible to send specific information to the client and different information to the agent instead of sending [_form_results_] to both parties.

the agent only needs specific information from the form and the client needs different information from the same web form.

Yes, You can customize the confirmation and notification to send specific variables.
If you open each within the form builder you click on the pencil at the bottom right. That will open a new design window where you can add the individual form variables listed in the drop down at the bottom.
