# Overview

Email marketing is one of the most popular ways to reach customers. However, with a large number of emails sent out every day, how do you know the percentage of successful emails and failed emails? How do you know out of 1000 emails sent, how many have been opened and read by customers?

All of that is now integrated in the Nobita system. And in the overview tab, you have complete control over the status of emails sent to customers.
