It's not exactly a shocker to get spam from a marketing company. I'm pretty sure I've received spam from this group before, but long enough ago that they're probably doing that "OK, you're unsubscribed, but just for a year, on the chance you might forget you unsubscribed."
Setting aside that iOS 14 is old news, what's with the "Hey,"? The ubiquitous "Hey there," is annoying enough, but just "Hey," is on the road to "Hey buddy! Yeah you there! Pay attention, I wanna tell you something!"
