Buy Button Adds Product to an Already Full Shopping Cart OR Overwrites Existing Shopping Cart Contents?

I am trying to add a Buy Button to my email campaigns for cart abandoners and would like to offer them a GIFT product if they continue with their purchase. From what I have seen with the Buy Button in the email is that it overwrites the previous contents of the shopping cart or create a NEW shopping cart with just the free gift in it. How can I make the button work so that it ADDS the free gift to their already inprogress shopping cart?

Thank you! :)
