Perhaps I'm confusing one kind of marketing spam with another kind of marketing spam.
It all makes me feel ill, to the very depths of my Soul.
"Order confirmations": not necessary. I should have a choice whether I use my email address to confirm an order.
"Transactional": I don't know what that means (I keep finding that term being used). I think it means that the email is being used as part of an agreed deal. Fine: if I've agreed to my email being used as part of a deal, no prob. Otherwise, leave me alone.
"Order confirmations": if I need my order confirmed, then I can opt for that, and give you my email. But in general, orders don't need confirming - you either order, or you don't.
"Password reset": My passwords are my business. I use a password manager. Please don't assume I'm a password slob. Passwords suck; they are an insane way to authenticate, they just don't work. So reset emails are not a good use-case for unsolicited email.
