It is just a regular link pointing to a named position in the email rather than a full URL.
	 
	<a href="#product1-link">Product 1</a>
	<a href="#product2-link">Product 2</a>
	 
	and so on
	Then define the tag where the section starts
	 
	<a name="product1-link">
	Please keep in mind you need the # sign to denote it is an internal link.
