Why would you want to cease all Jake emails? I don't mind them, makes me feel like a valued customer.
I get many, many spam emails that I wish I could easily stop. I don't even look at them, just keep hitting the delete key. We just need to understand marketing emails are here to stay and it can be very effective if managed well. I think Amazon have a good balance. I get emails most days from Amazon and they are advertising what they think I would like based on what I have viewed or bought. I don't delete these and in fact welcome them.
I also noticed that many web pages I go to have a Jake advert with a 10% discount. When I need more Jake, I just click the buttons that get me the 10% off.
