Condition to Add CC email based on Keyword Match

A bundle that is passed on may or may not contain the word “Wellness”

Would the below formula be a proper way to add a CC address? If the Clinic contains Wellness, an email will be added into the CC section. If not, then the CC field will be empty. The problem I am facing is that the output is “null” if there is no match. I want the CC field to be empty.

{{if(contains(17.Clinic; "Wellness") = true; ""; )}}

^^ does all of the above refer to the same CC address, or are you refereing to a CC #, field and CC info array respectively.
