I received an email from Avaaz, a social campaigning organisation (www.avaaz.org) where they asked me to reply to avoid their notification emails being classified as promotional. I don't know how accurate that is, but it seemed surprising they were confident that could change the algorithm's mind. It sort of seems vaguely reasonable - you don't reply to promotional emails, but it also seems like something that would cause a lot of false positives. That said, that email ended up in notifications which seems correct, and I haven't seen anything misclassified into promotions yet.
