That means that our email filter thought it was spam. If this happens click on the link and enter the code to verify that it's not spam. Our spam filter will learn not to block those type of messages if you do this when it happens.
Did you update the subject line and body of the text? If the outbound spam filter is marking your outbound email as spam, it maybe something inside the subject line or body that it does not like.
