How can the dead send us emails? The ethical dilemma of digital souls

I suppose there's a real ethical problem with someone setting up emails to be sent after their death. And this article does delve into that a little.

But this situation seems unlikely. It's more likely that there'll be some commercialized emails from dead celebrities or what have you, a lot like presidential candidate Herman Cain's twitter account. Even after Cain died of Covid-19, his social media team kept tweeting from his account. That's an immensely more likely situation than the dead guy in the article. And we'll have to deal with it because a commercialization will happen way more often, and it will make someone wealthy. Once there's embodied wealth, then there's lobbying of politicians and incentives to write laws to keep around what we would otherwise consider an abhorrent, macabre practice.
