Abstract

A method includes identifying, from a multitude of raw domain name system records of a source domain, a domain name system pattern corresponding to a raw domain name system record. The domain name system pattern is categorized, by a large language model to obtain a pattern category. A feature vector of the source domain is generated based on the multitude of raw domain name system records and the pattern category. The feature vector is compared to a historical feature vector of the source domain to obtain a feature vector difference. The feature vector difference is categorized to obtain an email stack change event of the source domain. An email volume index score is calculated based on the feature vector and the email stack change event for the source domain. The source domain and the email volume index score are transmitted to a user application.
