Iamfreelancer, as u said as long as the visitors subscribe for newsletter by their own, but however, the mail server like hotmail, those are still categorize it as spam/junk mail as the user never add our email address in their contact list.

So, if there's necessery for sending out newsletter as you're doing online sales to your valued customers, which way will u do to avoid it categorize as spam?

Cause when up numbers of letter u've sent and all mail server like hotmail, msn or aol..they will detect the source and blacklisted. Once blacklisted, it's actually blacklisting your hosting's provider's mail server.

How to solve this problem?
