Before you get all uppity, I'm talking about these:

Now I hear you say, "It's because you bought, downloaded, or otherwise interacted with or supported this developer and/or their game," and no, I have not. "You may've forgot you had," no I did not, I've thoroughly checked through my activity. I've no form of previous interaction with these developers or games whatsoever.
I get probably two to three emails similar to this a month. From a developer I don't know, about a game I've never played.
You can unsubscribe from them, but you only unsubscribe from that specific developer's mailing list, not all communications like this.
I've gone so far as to reach out to a few of these developers over time to ask how they got my email, and the responses have been mostly similar confusion. As far as they've been concerned, I was on their own curated email lists, despite having never touched their game in my life.
The only thing I can think of are bundles. If you buy a bundle— one with a thousand items— is your private email put on every single one of these developers' email lists? And is there no way to not have that happen to even remove yourself from all of these new lists you're on?
