Will using the word 'Free' in the Subject Line of my Template case my messages to be caught in Spam Filters?
The word "free" can cause Spam Filters to flag your message as spam. Various ISPs use different levels of filtering. Even though the Content Analysis tool does not report any issues with the word 'Free' in the Subject line, a specific ISP may block an incoming message that uses that word in the Subject.
If it's not necessary to include the word "Free" in the Subject, it may be best for inbox placement to leave it out.
