Hello,
I received the following email from my webhost regarding my first email blast of 2500.
Why did this happen? How do I avoid this on my next mailing?

"The mail was delivered to undisclosed AOL email addresses. As you can see from the content of the message, this could easily be considered spam by a recipient who had not requested such information."

Received: from undisclosed@undisclosed.com
X-Mailer: 9.0 Security Edition for xxxx@aol.net
