What does GXG stand for in mailing services?

GXG stands for Global Express Guarantee, which is a service provided by mailing and shipping companies that ensures fast international delivery of shipments, typically in one to three business days to select destinations. This service is particularly valuable for businesses and individuals who need reliable, time-sensitive deliveries with guaranteed service levels, including money-back guarantees if items are not delivered on time.

The service typically includes online tracking capabilities and may also offer options for customs clearance assistance, making it a comprehensive solution for international shipping needs. This is an essential aspect of mailing services, showcasing the importance of reliability and speed in the logistics industry.

The other options mentioned do not accurately represent the GXG acronym as established in mailing services, as they either imply different meanings or do not correspond to recognized services in the context of shipping and logistics.
