Recently, I have been asked about how effective the email marketing is for CPA offers nowadays. Since I am not in this area, I cannot come up with valuable answers to my clients. Because of this, I have done some information gathering on the net. It seems to me that only the opted in lists are safe to market with email blasting method. Also, I could not find a really clear explanation on SPAM.
Can our fellow warriors give me some detailed info on this?
Thank you all in advance.
