I have a highly visible Subscribe Form and several other links to my Newsletter Subscribe form on my website, but people always prefer to 'subscribe' using the 'wp_???' (I forget the HTML code they use) subscribe method which adds them to my site's Users list, but not my Subscribe Form List.
So I add them manually to my Subscribe Form List of Subscribers (Mailchimp) and send out emails, but no one ever opens them. Maybe one out of my 70 subscribers who have 'subscribed' this way.
Question 1: Why do people prefer to become Users, not Subscribers? What is 'in it' for them?
Question 2: Why don't they open my Newsletter emails, when they went to the trouble of becoming Users?
By the way: I know I don't have a freebie give-away to get more Subscribers via my form yet, but I'd like to know why these people even bother to become Users if they arene't interested in opening my emails.
