Classic email marketing is easy: There’s three parties, and everybody wants to get a piece of the cake:
- The Marketer is making money by selling products. They are paying their Email Service Provider.
- The Email Service Provider (ESP): Is paid by the Marketer, usually with a CPM-based model (the more emails are sent / delivered, the more money is paid).
- The Internet Service Providers (ISPs) are offering free mailboxes to end-users and make money with more or less personalized display advertisement.
