apply, to each sentence of the email, the corresponding classifier to classify each sentence of the email to generate classified sentences;

an information extractor, executed by the at least one hardware processor, to
extract, from each of the classified sentences of the email, at least one entity; and

an email classifier, executed by the at least one hardware processor, to
