1. Open Rate: Indicates the percentage of recipients who open the email. 2. Click-Through Rate (CTR): Measures the percentage of recipients who clicked on one or more links within the email. 3. Conversion Rate: Tracks the percentage of recipients who completed a desired action, such as making a purchase. 4. Bounce Rate: Shows the percentage of emails that were not delivered successfully. 5. Unsubscribe Rate: Reflects the percentage of recipients who opt out from the email list.
