Just joined 1stepsystem 7 days ago I noticed in my 1step email my bulk were full of "mail return to sender or failure delivery" my email letters got to my prospects but when they signed up to listen to tele seminar, 1step follow up email never got to their inbox or bulk, they should change every now and then their mail server, how can we run an effective email marketing system if most of their follow-ups never got to our prospects,

if you will say some of my prospects emails have spam...
