I've found that on occassion during my daily tests of email blasts I'll inadvertently click the unsubscribe button, which of course moves my contact onto the DNM list. However, it remains on the Test List, which means I'll send myself a test and wait and wait and then contact Chat and ask them to send the test...only to discover I've been DNM'ed. I suggest that if a name is placed on the DNM, it should be removed from other lists.
