Editing the layout of emails sent to me via Enfold Contact forms

Where can I find the file that controls the output of emails sent from Contact Forms?

I want to add some extra info to the emails and add line breaks to make the email easy to read.

Example of existing output :-

First Name: Sean
Family Name: xxxx

Confirm Email: (Email address hidden if logged out)

What date will you leave Bangkok/Thailand?: 30 / 11 / 2016
Have you booked a clinic? If so which one?: Not yet
Do you need recommendations on clinics/hospitals: Possibly
Which procedure have you booked and how many days do you expect to be in the hospital/clinic?: Lasik. 1 day
How many days would you like to book one of our MED-Friends?: 1
And for how many hours per day?: 2

How I’d like to have it formatted :-
