The open rate is a key email marketing metric. It tells you how many recipients actually opened your email campaign. Open rate is calculated by dividing the number of unique email opens by the total number of emails delivered.
Open rates are important because they help you guage interest. A high open rate shows that the subject, preheader and email content were well received by your target group. The open rate depends on several factors, such as the quality of your email list list, contact segmentation, and send time. Other factors such as spam filters or inactive addresses can also affect open rates.
Crafting effective subject lines, personalizing email content, and optimizing send time all help to increase open rates and improve the success of your campaigns.
