Acceptable Spam Report Rate
This is inevitable, you are probably going to get marked as SPAM at some point, but how harmful can it be? The Acceptable Spam Report Rate shows you the preferred rate at which you can be reported as SPAM and be able to still mantain the reputation of your sender. As a guideline, you can consider a rate of 0.01%, or one SPAM report per 1000 email messages. You will normally receive a warning every time you go past this limit.
