As you ship packages you should include a postcard or form that makes it easy for your customers to join your list. They can send this form back to you, and you can enter their email address manually. Another option is to explain the advantages of being on your list and direct them to a website where they can go sign up themselves.

This is a great strategy because you know that the people who are receiving a shipment are proven customers. That means there are a lot more likely to be responsive.
