Systems and methods can support change management thresholds within human machine interfaces. An operation or feature may be introduced into a multi-user information system where a benefit is conveyed to specific benefited instances of events. A user indication associated with the specific benefited instances may be initially disabled. A quantity of the specific benefited instances may be calculated or counted. The calculated quantity may be compared to a threshold quantity. The user indication associated with the specific benefited instances may be enabled in response to the comparison indicating that the threshold has been exceeded. The user indication may be presented via a user interface mechanism associated with the multi-user information system. According to certain examples, sender authentication may be added to an email system such that instances of authentication are not displayed until a certain number or percentage of messages is being authenticated.
