Brief history of open rate

The concept of open rate as a metric for email marketing can be traced back to the early days of email as a commercial medium. In the early days of email marketing, the only way to measure the effectiveness of an email campaign was to track the number of emails that were sent and the number of emails that were opened. This led to the development of the open rate, which is defined as the percentage of emails that are opened out of the total number of emails sent.

Over time, the definition and calculation of open rate have evolved. In the early days, open rate was calculated as the number of unique opens divided by the number of emails sent. However, with the advent of email tracking technologies, it is now possible to track the number of opens per email recipient, leading to a more accurate calculation of open rate.

Today, open rate is widely used by email marketers to evaluate the success of their campaigns and make data-driven decisions about how to improve the effectiveness of their emails. It is widely considered to be one of the most important metrics for measuring the success of email marketing campaigns, as it provides insight into how many people are actually engaging with your emails.
