Need emailing help landing in the inbox

hey guys hows it going, I'm not sure if this is the right section but since the mass emailing section isnt here any longer I decided to post it here

Well im running a campaign with POF and was getting a pretty high epc until I started landing all my emails in the spam folder rather than the inbox.
These people are emailing me first so I feel like there is no reason that my responses should be going into the spam folder...

Does anybody have any knowledge on mass emailing, or have any methods that can help my responses go into the inbox rather than spam folder?

thanks a lot guys
