Hi, For those who try co-reg leads, it can generate large list in short time. Even lots of "gurus" like ewen chia, Jimmy D Brown using it. The problem with co-reg leads is email deliverity problem. If you use the wrong autoresponder services your mail will end up in spam folders or even never get delivered. I shopping cart is one of the best option since they accept single opt-in (leads already double opt-in at the co-reg co) But recently 1shopping cart change their rule and doesnt allow this anymore though lots of co-reg company still show 1shopping cart is one of the autoresponder option.
