What type of mailing service is specifically designed for bulk mailings?

The correct option is specifically tailored for large-scale mailings, allowing for cost-effective delivery of numerous items at once. Bulk mailings, which are often used by businesses and organizations, take advantage of discounted rates through the postal service. This type of service typically involves sending advertisements, promotional materials, or other forms of communication to a large audience, making it efficient for marketing campaigns and other outreach efforts.

Standard Mail, while associated with bulk mail, refers more broadly to a class of mail that includes various types of marketing materials but does not concentrate solely on bulk rates or the specific requirements of bulk mailing. Priority Mail and Express Mail serve different purposes, focusing on faster delivery rather than bulk rate considerations. Therefore, the term that best encapsulates the idea of mailing services explicitly designed for large quantities is the one highlighting bulk mailing.
