Shipping Rules are if/then statements that enable ShippingEasy to take actions automatically. A good example of a Shipping Rule would be something like:
The Total Weight of the Order is less than 1 pound
Assign my First Class Saved Selection
Put the Order in my First Class Order Category
Automation Rules can be created that do almost anything to make life easier. The more familiar you are with what Rules can do, the more efficient and streamlined your shipping process will become.
