Automation Rules can be run against one or more unshipped Orders. Orders can come from an e-commerce system, MS Excel, or manual entry. Depending on the parameters set for the Automation Rule, it can:
Set Shipment weight, Service, packaging, and other aspects
Rate shop and select the least expensive option
Rate shop and select the fastest option
Apply templates
Automation Rules can be run manually, or automatically using the Lights Out Automation feature.
Warning: Automation Rules can save you a significant amount of time. However, use them with care. They can do many things automatically, such as print shipping labels, and debit your postage and shipping accounts. Always test each Automation Rule on a small group of Orders (or on a few Orders that you created for test purposes) before applying it more broadly. Know and understand the Shipping Services in detail. Read all relevant documentation before auto-shipping orders.
