There are several metrics commonly used to measure recipient interaction:
Open Rate: The percentage of recipients who open your email. High open rates indicate that your subject lines are compelling and your sender name is recognizable. Click-Through Rate (CTR): The percentage of recipients who click on one or more links in your email. A high CTR indicates that your content is engaging and relevant. Conversion Rate: The percentage of recipients who take a desired action, such as making a purchase or filling out a form, after clicking through your email. Bounce Rate: The percentage of emails that could not be delivered to the recipient's inbox. High bounce rates can indicate issues with your email list quality. Unsubscribe Rate: The percentage of recipients who opt out of your email list after receiving an email. Monitoring this can help you understand if your content is causing disengagement.
