For the sake of this article, let us just assume that you already have a subscriber list of several thousand, and have been mailing them regularly.
Initially, your list was relatively responsive, and you were making a nice sum from your list each week.
Unfortunately, though, as your list has grown, your list has become less responsive.
First off the bat here, let me tell you this - the responsiveness of your list will go down as it ages.
So there is no cure-all.
What we can do, however, is try to rejuvenate the list, by getting the people on it excited about the subject matter of your list again.
But you still must recognize that some people were looking to buy something specific when they joined your list, and at this time they are no longer interested.
You cannot fix that.
What you can do is improve the responsiveness of the people on your list who are no longer opening your emails.
One of the things that I have found to be very productive to increasing the responsiveness of my list is to send them free gifts.
I buy or create short ebooks to give away as free gifts, and use the 'free gift' in my subject on my email campaign, and my response rate goes up - and not just for that email, but for following emails.
Another thing that you can do to help improve the responsiveness of your list is to ask questions of your list.
Ask them what they want to learn more about.
Answer the questions mailbag style - all at once in one big email - you really create the illusion of a very responsive list and since people tend to do what others do - if they see that the rest of the list is responsive, they might do the same.
