Sending email with list

Hi All,

Hope you are well. I am creating an app where users will have a list of items (with their own properties) attributed to them and they can add and remove to this list as they need to.

What i am looking to do, is email their full list to themselves with the click of a button. I have set up the custom action, but i can only pull the count of the items and not the list. Any suggestions?
