FedEx Corp. customers will now have more flexibility and control over their delivers with its newly launched service, FedEx Delivery Manager.

The service, which is free to sign up for, is designed so that customers will have a better idea of when and where their packages are delivered. Customers can reschedule a delivery day, deliver to another address and request a two-hour delivery window for a small fee.

In addition, FedEx will allow customers to put a two-week vacation hold on deliveries and leave delivering instructions, such as which door to deliver the package, free of charge. Customers can also sign up for free delivery alerts via mobile devices and the web.

According to FedEx officials, the service launch comes from the growing popularity of online shopping. The U.S. Commerce Department reported e-commerce spending is up 16 percent year over year in 2012.

The new FedEx service and its prices mirror the UPS program, My Choice, which was launched in October 2011 and has attracted more than one million consumers. However, FedEx offers its program with the option of a “premium” plan at an annual cost of $40.

In Internet Retailer’s Top 500 Guide, FedEx assists 124 retailers, while UPS assists 146. In the Second 500 Guide, which includes smaller retailers, FedEx assists 184 retailers, while UPS assists 249.
