That's another name for spam.
i.e. juggle between allowing allowing some paid spam and not being outright blocked by google/microsoft. That's the service they provide: VC-backed connections to get traffic unblackholed on behalf of their spammer customers.
The fact that you have to frame it your way speaks mostly to the fact that apparently your income depends on spam being seen as acceptable and not a scourge to humanity. But that's just my perspective...
But it almost never is, isn't it?
I'm sure you'll get mostly useful feedback.
Define "low quality" and "not liked". Each person will classify a given message differently. At least in the general case it's hardly realistic to expect a sender to classify a message from the perspective of a specific recipient prior to sending it.
On the other hand, it is reasonable to expect addresses to be acquired via legitimate means (ie collected only with the consent of the recipient) and to cease attempts at contact when requested. That's essentially the boundary between reasonable conduct and harassment.

Therefore: that's how I feel about my e-mail, meaning let's send a billion messages a day, surely a billion people also feel same as me about it.
Me personally I won't give a pass to business with an unsubscribe link, I have extreme disgust that we're in some make-believe pretend world that I asked for this in the first place
