Which advantage did email provide as a mass notification tool?

Answer

The ability to send multimedia content and long text blocks.

The introduction of email into notification systems brought significant capabilities beyond the limitations of paging and sirens. Unlike short alphanumeric codes sent to pagers, email permitted the inclusion of attached documents, images, and comprehensive text, allowing organizations to provide context-rich information rather than just a simple notification of an emergency.
