I had a student tell me that they had a list of non-responsive subscribers and wanted to know what they needed to do to make their subscribers buy. Well, the answer is simple, send http://abcnews.go.com/topics/business/black-friday.htm more emails!
I believe the more emails you send out, the more money you are going to make. The analogy I have used before is of a hotel. The more times that a hotel room is not booked out, the more money the company is losing. So therefore, think of your list the same way. The more you can book that room, the more you can send out emails, the more money you're going to make.
There are, however, a couple of things you want to look at in your analysis. One, if your subscribers are not opening up your emails, then it's obvious they're going to be unresponsive too, so you've got to write good email subject lines that have a good hook that's going to get them to open up the email.
Also, if you get them to open up your emails, then the next question you've got to ask yourself is how is your copy? Are people clicking on the links and going to the pages where you want them to go buy? Is your copy good enough? Are you enticing your reader? The copy itself could be the answer to the question. You also need to look at the sales letter copy and look at its strength. Then, if you find that none of these suggestions are really working, then you've also got to look at the quality of the subscribers that you have on your list. Where are you getting your traffic from? If you're using articles, you've probably got a good list. If you're using Google AdWords, you've probably got a really good list. If you're using joint ventures, you've probably got a really good list there too. So understand what you are doing and how you are getting those subscribers and make decisions based upon that.
Another thing as I have mentioned before, is to send them love. Let them know that you value them by sending them something, maybe even a free gift. However, don't train them that all they're going to get is free stuff from you. You want to train them that you're going to be selling them 2016 best cyber monday deals stuff. That's a really important thing for you to do.
Good marketing, constant contact and trust are key factors in making the sale.
