Auto sending of survey response to specific individuals based on a directory contacts embedded data

Hi Qualtrics users!
I'm hitting a brick wall and I'm hoping I can some advice.

What I'm trying to achieve is as follows:

My company runs an annual NPS/relationship survey with our customer base
The directory holds around 6000 individual customer records of those customers who will take part each year in the NPS survey.
Each customer directory records holds lots of embedded data fields, including who their internal contract manager is at our company (name/email address, job title).
What I want to do is when the invites are sent and a individual customer responds and completes the survey I want that individual customers survey response (including the PDF copy) sending automatically to the internal contract manager at my company.
Now of course each customer contact may have a different internal contract manager…

I’m really hoping there is a simple way to do this, and maybe there is!
I can see how alerts can be set up based on survey response but I’m really struggling to make the connection of how I can set up the email alerts in the way I want it to work

Any help would be gladly received!
