You can send something each week, or just once a month. Send a favorite new product for each customer. If you pick out a few different ones to start, you will be able to find a single favorite for almost every name you have.
If you send a favorite to people once every few weeks, you eventually get their attention and their business. It is amazing what this can do for you if you are consistent over time. Even if you just connect quickly about anything at all, many more people will later want to order from you later. See more work at home ideas here
