A user can be assigned to one of a plurality of filtering profiles to filter the user's incoming email messages. Each filtering profile in the plurality of filtering profiles filters the incoming emails according to a different set of filtering rules. The filtering profiles are applied to incoming emails, and the emails are delivered according to the rules of the currently-assigned filtering profile. The user's actions on the received email is tracked to determine a first performance score for how accurately the first filtering profile is filtering incoming emails of the user, and if the first performance score is less than a score value, the user might be assigned to a different filtering profile.
