Many customers do not utilize email or may simply want to keep their identity private. Thus, many store owners create a false email address for the customer to use. One issue that often arises out of this is keeping them all straight. Although customer records are now allowed to have the same email address as another, if something goes wrong, the orders can get mixed up and cause plenty of confusion. Now, you have the power to generate a safe email address that is easily distinguishable from legitimate addresses and ensures that it is always unique.
To generate this email address, navigate to People > Customers > New or Edit Customer from the admin console. Next to the Email field for the customer, is a "Generate" button. Clicking this button will generate this customer's unique email address.
