I strongly agree with this recommendation. Most sophisticated SMTP servers have the ability to parse headers for a multitude of reasons. In our case it would be to distinguish our broadcasts for statistical purposes. Using a unique header identifier on a per broadcast basis would make this possible. Thanks for considering this addition.

On page 120 of the manual, it says you can use any of the personalization tags in a custom header.
However one does not work for autoresponders. Can you enable this?
{MESSAGE_NUMBER}
Also I would like to be able to insert the subject line for broadcasts into a customer header.
Can you add this. It would be something like this:
{SUBJECT}
