I have a client who needs to send out email to large lists of opted-in subscribers.  Some of the email content contains words that would ordinarily trigger content-blocking filters and firewalls.  Examples are things like How to prevent sexual assault and Breast cancer awareness.  Overly aggressive filters and spam firewalls would obviously see some words there and prevent delivery.  Is there a way to avoid that?
Is there a way to get legitimate but spammy words past filters?
