Aside from the amateur mimicry of a legitimate Yahoo email and the boneheaded use of TinyURL.com to create the "UPGRADE NOW" link (something Yahoo would never do), the sender is clearly not aware of one little trick: hover over the sender name with your cursor and see the real email address.
In this case, it's "holyfparish@outlook.com".
Can't see that email going to anyone at Yahoo.
Again, nice try, bitches!
