Thanks Eric, that was a good email debuging sugestion. There were 3 Parse error: syntax errors in the WAUE_IPN.php email code. Because it was an ipn I would not see the errors and the page would fail.

My links should have been without the extra \, like this:
<a href=\"https://www.website.com/webpage.php\">Click Here</a>
So now the email is comming through to the customer's email (and mine temp. durring testing) as it should.
However, the next problem... the cart values for the item level: product SKU and the two ACTIVATION CODES are NOT BEING SENT IN THE EMAIL. As you will note in the code I generate (DA Random Password behavior) and update the db that Shipping Tracking number on the IPN page. In this case I need the values sepecific to each product item in the cart. The SKU is not important as the product name is sufficient, but the two Access Codes for the pass activation is very important. What is the best way to handle passing these values through PayPal? And where and how would I add this in the code at this point? Or does it need to go through pp?
