Include the item the customer bought in an Email

I’m using the shopify reviews app but since it doesn’t have an ask for a review via e-mail feature i thought i’d create one with the shopify e-mail app but there is no segment to display the item(s) the customer bought. Would it be possible to do this with liquid and if so how?

Would it also be possible to check whether or not the customer left a review or not so i can send a coupon?

This is not possible. You need to use some other reviews app that offers this functionality.
