Open Rate: The percentage of recipients who opened your email. Click-Through Rate (CTR): The percentage of recipients who clicked on a link within your email. Conversion Rate: The percentage of recipients who completed a desired action, such as making a purchase. Bounce Rate: The percentage of emails that were not delivered to the recipient's inbox. Unsubscribe Rate: The percentage of recipients who opted out of your email list.
