I hate receiving an email ad from a company that I recognize when I can’t remember for certain whether I signed up for email or not. Did they just reactivate an old list that I’d forgotten, or have they been acting shady, picking up email addresses but not permission?
If it’s an old, forgotten list that I really did sign up for, I should just unsubscribe and have done with it. Reporting them as spam would be irresponsible and would actually make spam filters less reliable.
On the other hand, if they harvested or bought my email address, I should report it as spam…and I shouldn’t trust the unsubscribe link.
