The open rate of a newsletter is the number of recipients who have opened an email. A distinction is made between the total open rate, where all the opens of a single recipient are counted, and the unique open rate, where only the number of recipients who opened the email, but not the number of opens, are counted. The latter is calculated as follows

Unique opens : (number of recipients - bounces) * 100.
