I am going to start building a new list soon and me and my friend have decided to share our Awber account to cut the costs. Now I am not sure if this is a good idea or not. I am scared that in the future if he decides to stop paying for Awber, the account will shut down and I'll lose my list. Also, he is planning on building lists targeted to different niches, so I am not sure if that will look good to my list. Also, there is a possibility that he sends an email to the wrong list, he is not so good with computers and the internet so I am not sure if he will know what he's doing.
Is this a good idea or not?
