Identifying your target market is key. Your target market is the group of people who will buy your cards. Getting the word out about your product is your marketing plan. Knowing your target market will help you define your prices and determine where to market your cards. For example, if you sell cards which will appeal to hipsters, your target market is going to be very different than if you are selling cards for a kid's birthday.
The presentation of the cards—the packaging—helps make a successful handmade card business. A card that is neatly presented in a cellophane envelope looks more professional and can command a higher price than one that is unpackaged. Presenting cards in some form of packaging stops cards from becoming dirty or dog-eared and it also gives the ideal opportunity for further marketing. A label on the back with your phone number or website address could help you solicit further orders. Remember to consider shipping and packaging when factoring the costs per unit in your pricing formula.
