The answer lies in tracking. Tracking how well your emails perform is one of the greatest benefits of an email marketing strategy. Tracking how well an email does is amazingly simple and ESPs provide the necessary tools for you to be able to do all of that. Depending on the ESP you use, you have a great deal of data and to track and analyse. The kinds of data you can track include, but are not limited to, the following:
1. Email bounce rates
2. Who opened emails?
3. What links were clicked
4. Customers that unsubscribe
