In order to generate some business for my new company, I am sending out emails to a select group of prospects. I sent a bunch out, including one to my friend's email address just to see how my emails would look when they were received by the recipients. My sent emails are not going to the "Inbox" category of the recipients, instead they are going to the "Spam" inbox. Why is this happening? Is there any way I can make sure that the emails go to the "Inbox" rather than the "Spam" box. Any help greatly appreciated.
