add customer email preferences to bottom of emails

[alanrichardtex]

Hi, i created a code for my customer registration page that adds selection for customers to choose which type of emails they want. I am trying to figure out how to also add that code to the emails i send out. i am using shopify emails, so it gives the option to add "custom liquid". Can someone please help me adjust the code with the portion needed to make it work on the emails?

this is the current code i use for the customer registration, and the selections are toward the bottom. and below that is am image of how the options show on the registration. i want those same options to show at the bottom of my email by using the custom liquid option. 

Thank you
