itβs likely an extremely low percentage of users
its not, its actually a pretty high percentage, the conversion rate of pop up email form to static forms in the footer or header are like night and day. Static email sign up forms are lucky to see a 1% conversion. The average pop up conversion rate for emails pop up with incentive (like a discount code) in 2024 was 7%.
If people stopped filling out the pop up forms they would go away, but people still continue to bite so they live on.
Happened to my mom IRL too, way back before I was born, in like 1970 her sister gave her a set of three elephants that she displayed on a shelf by the front door. People coming over thought she liked elephants so people started gifting her elephants. By the time I was born she had a full fledged elephant collection, multiple shelves worth. I even added to it when I was a kid because I thought the same thing until she told me one day that she doesn't really have any type of interest in elephants, it was a collection that other people made for her.
