• Keep your Message Unchanged

Unlike most spam blocker software products usually do, SpamArrow^TM will never modify your original email message. Most spam filter software will add a special mark such as '***spam***' to your email subject line and use Outlook Express internal Message Rules to move the marked junk emails to the special 'spam' folder. This will cause problem while some legitimate emails are mistakenly identified and marked as spam. For example, when you reply the email marked as ‘Spam' and forget to modify the subject line, the email receiver will never receive this email if he or she uses the same spam filter software. Obviously, this email will be automatically moved to the 'spam' folder as the result of the mail rule pre-defined by the spam filter software. If your friends reply to this email fortunately, you will find this email in your 'spam' folder too due to the same 'Spam Mail Rule' reason.

SpamArrow^TM spam blocker will never add message rules to your Outlook Express. Your email message will keep as the original. That's an exclusive feature of SpamArrow.
