I took a look at your account and saw that you are using our newest editor. @Clique_Marketing is correct, the help page has not been updated to reflect that the spam check is not yet available in the 3GE editor. I apologize about that, and thank you for bringing it to our attention! Here are a couple links with information on how to optimize your email and subject line to avoid being caught in a spam filter. I hope those help and I'll post here with any updates on the spam check feature for the 3GE editor.
