1. A method for managing email in an email system, the method comprising: providing a plurality of topics, a reference associated with each of the plurality of topics, and a defined importance value for each of the references; preparing a topic relevance algorithm for each of the plurality of topics, each topic having associated attributes, and each topic relevance algorithm formed by estimating a relationship value between a topic and its associated attributes based on defined relevance of reference, characterized by; preparing an importance algorithm comprising weighted importance attributes formed by estimating a weight for each of the importance attributes based on defined importance of the reference; assessing a target mail using the topic relevance algorithms to determine a topic relevance and against the importance algorithm to determine an importance; determining that a target mail has a threshold importance for a particular topic relevance; and based on a determination that the target email exceeds threshold importance, calculating a criticity of the target email and raising an alert, wherein a type of the alert is based on the criticity, wherein the criticity is a function of the topic relevance and the importance, wherein the types of alerts include: sending a text message to an intended recipient of the target email if the criticity is below a first threshold; placing a call to the intended recipient of the target email if the criticity is above the first threshold and below a second threshold; and dispatching a person to contact the intended recipient of the target email if the criticity is above the second threshold.
