[Australia] Email Scam Yeti Outdoor Bundle

Hi all... I started receiving emails saying You Succeeded a Yeti Outdoor Bundle. I was ignoring them. Just now however I opened one up and scrolled to the bottom. It looked like it was promotional stuff from Buzzfeed, and I saw the Unsubscribe link and without thinking I clicked on it. I quickly realized and closed out of the window, but now I'm nervous about what I've potentially opened myself up. What steps do I need to take now?
