With the help of the Mass Mail Prevention module, you can protect your company mailboxes against mass mail. Mass mail refers to email messages that are generally sent by email marketing services in large numbers by subscription and are not detected as spam. For example, newsletters or marketing emails are detected as mass mail. If you consider messages containing business offers unwanted, they can be optionally treated as mass mail.
