Pop ups should be easy to close. Nothing is more annoying than having a pop up appear and you do not know how to close it. Sometimes your visitor may not be interested in what you have to offer and so will decline the offer by closing the pop up. If the ability to close the pop up is difficult, such as the exit link is not visible, you can lose visitors. Therefore make sure that your pop up can be easily closed to avoid losing readers.
After you have entered your "List Name" you will need to enter a "List Description." Here is where you will describe the kind of information you'll be sending from this list. There is a 400 character limit for the "List Description." Subscribers will see your "List Description" on the unsubscribe page if they ever go to unsubscribe from your list. Once you are done entering your "List Description" click the "Next Step" button.
