Specifically, you’ll have to verify your email address, and opt in to marketing emails. You have until the end of June to do so. In fact, you have until 2:59p EDT on July first to do both of these actions. Having done this, you can receive a free Infernium Dwarven Spiderling pet.
To verify your email, you’ll need to log into the website. That’s pretty much it. If you’re able to log in, then you have a verified email address. For console players who have not verified their email address, check out this article. If you’re still having issues, you can recover your account here.
To opt in to marketing email, log in to your account, go to Options, and select Account. Next, under Marketing Preferences, enable marketing emails. This can also be done on the site, linked above. Do note that by opting in, you’re letting Zenimax send you news, trailers, and sales.
